Android Battery Life, a pretty successful website has been made in order to help android users achieve better battery life while still using many functions and apps. All of these guides are available, with screenshots, at www.androidbatterylife.com
It's my 2000th post here on xda, and I wanna make it special
PORTAL! http://www.xda-developers.com/android/battery-saving-mega-guide-celebrating-users-2000th-post/
A lot of users are thinking that everything mentioned should be applied. You don't have to apply all of them, just apply what you think works for you. This is more of an index of guides, if you will.
Yes, this is in the Android Q&A, Help & Troubleshooting because of the word "Troubleshooting"... I'm shooting your "Low battery life" trouble in the face.
So let's begin:
The guide is split into 3 parts: Easy, Medium, and Advanced.
First up is... you guessed it..
Easy
Screen / Display LINK
If you go to Settings>Battery, you’ll clearly see that “Screen” has the biggest bar of about 40-60%. The bigger the bar (and the number), the bigger the battery drain. We’ll try to lower that bar as much as we can.
Brightness
First of all, to reduce the battery drain caused by the display, click on the Screen button, then click display (it’s the same as going to Settings>Display), then click on brightness, untick Auto-Brightness if it’s ticked and lower the brightness to minimum.
Explanation: A brighter screen means the screen is emitting more light, which consumes more battery. So lowering the brightness makes the screen use less battery juice.
Wallpaper
Second thing to do to reduce the “Screen” battery consumption is having a Static Wallpaper, and not a Live Wallpaper. So go to Settings>Display and click Wallpaper, and pick any wallpaper you want except the wallpapers from the Live Wallpapers list.
Explanation: Live Wallpapers use the CPU (and possibly the GPU) to make the image move. So the phone is using the CPU to process these images, which means more battery sucking, and we don’t want that.
Sleep
Again, go to Settings>Display, and click Sleep (aka screen timeout) and set that to something less than 1 minute. I personally use 30 seconds and it’s good enough for day-to-day use.
Explanation: The more time the screen is on, the higher is the battery usage, because the screen won’t be using the battery when it’s off…
Framework Animation
Fourth thing to do is disable the Framework Animations. Framework Animations are the animations you see when you switch from an app to another app, or when you press home, or back, or recent apps buttons. To turn those off go to Settings>Developer options (if you don’t see that, then go to About Phone and press the Build Number button 8 times, then go back), scroll down to drawing section, and set Window animation scale, Transition animation scale, and Animator duration scale to “Animation off”.
Explanation: Framework Animations use the GPU (and possibly the CPU) to draw the frames of the animations, so by turning them off, you’re pulling some load off of the GPU and CPU to make the battery life better.
Widgets
Believe it or not, widgets can greatly affect battery life, it's because they update themselves regularly. This can wake up the phone a lot of times. So the best way to prevent this is to remove all the widgets on the homescreen.... and maybe keep the ones that don't update themselves much.
Remember, everything that’s shown on-screen that isn't app related is registered as “Screen” in the battery window. So to lower that, you have to compromise every little thing that’s shown on the screen.

Google Services LINK
One major issue you may face with Google Services is the location battery drain. This was born in Android 4.2.2 and can be easily fixed by just unticking a button.
Problem
The real problem is, in one word, Location.
Google Services such as Gmail, Now, Maps, and Google+ constantly polls your location using your wifi (if you're connected) or your cell network. And every time Google Services poll your location, your battery gets affected. So what's the solution to that?
Solution
Further research by Galaxo60 proved that going to Settings - Location Settings (or Location on android 4.4), and unticking WiFi & mobile network location (or setting the Mode to Device Only) prevents Google Services from polling your location, thus preventing the battery drain
So disable the WiFi & mobile network location option, and actually tick and turn on GPS satellites. (It's just like setting the Mode to Device only on KitKat)
But why do that? Why should I turn on GPS?
Picture taken using Android 4.4 KitKat
Explanation
Google Services don't use your GPS to poll your location, so your GPS actually stays offline most of the time; and the reason you should enable GPS is to "Let apps that have asked your permission use your location information".

Go Dark LINK
Some devices have AMOLED or SAMOLED (Super-AMOLED) screens, like the Samsung Galaxy SII and the Motorola Moto X. The following method is helpful for these kind of devices.
You may check what's your screen type to see if it's AMOLED or not. If it's not, this method won't help you achieve better battery life, but may help your eyes
What's AMOLED?
AMOLED is a screen type designed to get the highest contrast a screen can get to. Black pixels turn themselves off, unlike the IPS screens that always require a backlight. So AMOLED has less battery consumption than most screen types.
What to do?
Try turning everything as dark as you can. So make the wallpaper have as much black areas as possible, and use dark apps. The best way to convert most apps to dark apps is downloading Team Black Out Updater. From that app, download the apps you want to make them darker and install them. Some apps require having root because you have to flash them via recovery.
This consumes less power
This consumes more power
Explanation
By turning most things dark/black, more pixels in the AMOLED screen will turn off, thus lowering the power consumption caused by the screen.
Remember, this is only for AMOLED screens, IPS/LCD screens will still consume the same power from the battery.

Turn Off Auto-Sync LINK
Auto-Sync constantly checks the data on the phone and the data on the cloud, and adds the missing files. In other words, Auto-Sync = wasted battery.
Turn off Auto-Sync
Go to settings, scroll down to you google account, tap it and tap on your gmail. Then uncheck all the items on the list.
This is wrong. Now untick them!
Explanation
Auto-Sync consumes a lot of data and battery. By unchecking the items, Auto-Sync will turn off, and thus saving battery AND data!

Turn Off NFC LINK
NFC is wireless, and wireless consumes battery. So turning off NFC will make the battery life slightly better.
NFC off when not needed
If you don't use NFC, go to settings > more > and turn it off. Android beam will grey out because it needs NFC, we don't need that either.
Explanation
NFC consumes a lot of battery if you keep your screen on most of the time. So by turning it off, we're improving battery life while the screen is on.

NO Task managers/Hibernators LINK
Yes... I know... Weird right? Don't be misguided, and understand what's happening inside android before doing anything.
Uninstall / Disable Task Managers / Killers / Hibernators
If you have any Task killer, or Task manager apps installed, either disable them if you can, or uninstall them.
Explanation
Android learns the way you use it. It knows which apps you like best and pre-opens them and puts them in RAM so that they get opened faster. Android keeps a log of how much time you've been spending on an app.
By using a Task killer, you're breaking this log, thus preventing Android from learning how you use it. The results?
Android will be loading every app you open from scratch.
Android will get slower.
Android will be wasting battery.
So uninstall those "battery killers" and let Android do the work instead.

Use ART LINK
Yes... ART... Not art, but ART... It's an Android 4.4 KitKat specific thing...
What is ART?
ART is a runtime replacement of the Dalvik runtime. It's the way the phone handles apps. Dalvik used to install apps fast, and conserve some space after the installation, but it compiles the app as soon as you open it, and runs it on a Virtual Machine (if it's not a native app).
ART pre-compiles the app on installation, which takes up a little bit (teeny tiny) more space, but makes apps faster to open, and over all performance better.
Switch to ART
Go to settings, developer options, and tap on select runtime, then use ART and reboot. It'll take some time to finish booting the first time it's running ART, but when it's done optimizing apps it'll be worth the wait.
Explanation
ART demands less CPU power to process things over time. It pre-compiles apps just once so that when you open an app, the CPU won't work as much to compile the app just-in-time (JIT). So, less CPU work, less battery consumption, more battery juice, and more performance!

Pick the correct charger LINK
I can't put direct links to chargers, so go HERE to the relevant page and see the chargers from there.
Is a fast charger better? or is it the slow one?
Use the Right Charger
A slow charger relaxes the battery, making it last longer when it fully charges. So, for a better battery life, use a slow charger at night when you're sleeping, or when you don't need to charge it quickly.
I recommend using this charger*: it's small, looks good, and it's slow with a 1A power output... Perfect for what we want.
If you're in a hurry, and your phone's battery has little juice left, you may want to charge it pretty quickly. In this situation, you won't care about the relaxation of the battery, so you should use a fast charger.
Something like this charger* should help a lot in achieving what you need. It also has a second slot it you have to charge another device. Use the A slot to charge faster with its 2.4A power.
You can also use a car charger if your phone's battery suddenly dies while you're not home.
This car charger* is perfect because it's fast enough to revive your phone and gives you enough juice to save the day.
So be wise and use the right charger for the right situation, so that you can achieve the best battery life possible.

Have a Spare Battery / Power Bank LINK
Sometimes, your battery will die, whatever you do...
Have a Spare Battery
In that case, if you have a phone with removable battery like any current Samsung device, equipping another spare battery could be very useful. If your battery is almost dead, just turn off the phone, open it up, and put your spare battery in. Voila, insta-charge
Have a Battery Bank
One great gadget to own with your phone is a backup power bank. This portable power bank (see link of the page HERE) is awesome because it's universal, and has a 13000 mAh capacity which can charge your phone about 5 times!
So if you don't want to scratch your head to do tweaks, you can use spare batteries or power banks to save the day

Know How to Use Android LINK
It's all about how you use it...
We see a lot of users that use Android the wrong way. We see people setting their screen timeout to 30 minutes because "whenever I want to chat, the screen keeps turning off". We also see a lot of users, even devs and power users, constantly pressing the back button to go home.
Know How to Use Android
If you have the screen problem where whenever you want to interact with the screen, it turns off, don't turn the screen timeout up. Turn it down, so that the screen turns off sooner, and saves battery.
And to go home, there's a button for that for a reason! Use it! Pressing back over and over again closes the app, and clears it from your device's RAM. When you re-open the app, it will open from scratch, so your phone will be slower, and will consume more battery since it's using more CPU power.
So use the home button, try to keep as much apps in RAM as possible, stop "clearing all" apps from RAM, and save battery!
Explanation
RAM, either full or empty, consumes the same amount of electricity, unlike RAM in computers.
The CPU copies data from storage to RAM and then runs the app. If the app is already in RAM, the CPU won't reopen it, it'll directly use it.
So making the RAM full of opened apps helps the CPU. The phone becomes faster, and the need of electricity running through the CPU to open the app is now nonexistent.
Also, Android keeps a log of how you use your phone and pre-opens the apps you need. If you constantly kill and clear out apps, you're breaking that log. So when clearing apps, you're not letting Android learn the way you use it. This results in a slower experience, and more battery drain.

Deactivate Auto-Rotate LINK
Auto Rotation isn't always needed... right?
Disable Auto Rotation
Go to Settings, Display, Rotation, and turn off Auto-rotate.
Explanation
Auto-rotate uses the phone's G-Sensor to see how you're holding the phone. By turning off Auto Rotation, you're using less hardware, thus using less battery

Turn on Airplane Mode LINK
When in low signal places, it's a hassle trying to find that precious signal...
Turn on Airplane Mode
Whenever you feel that the mobile signal is getting too low, turn on airplane mode if you don't need to call someone. Go to settings, More, and check Airplane mode to turn it on.
Explanation
The phone wants you to stay connected to a cell tower whenever possible. On low signal places, the phone will try harder to find a tower to connect to, and that drain a lot of battery. So turning on Airplane Mode makes your phone rest and not search for any tower, thus saving battery.

Use a Light Theme for LCD Screens LINK
AMOLED will consume less battery on the dark theme, LCD isn't affected by that...
Use a Light Theme for LCD
Using a lighter theme with more white in it helps your eyes, because you can lower the brightness even more and still see the screen just fine.
Explanation
The lower the brightness, the better the battery life. So a lighter theme is what we want, so we can reduce the brightness and still see everything.

Charge You Battery Correctly LINK
It's called a battery cycle, not a quarter of it
Charge it correctly
Don't let your battery go down to 0%, charge it while it's about 50%.
Explanation
No matter what charger you're using (either a slow or a fast one), the battery is greatly affected by the frequency of the charges. Our phones have different batteries than past devices had, so battery life cycles are a bit different as we used to think.

Use Widgets with Manual Refresh LINK
Widgets update themselves a lot... but there's a solution for that.
Use Manual Refreshed Widgets
Check every widget you have, and see whether you can set it to refresh whenever you click on it, or do something to refresh it.
Explanation
Auto-refreshing widgets make the phone wake up a lot and do some processing which can use the battery. By making them manual, you are controlling the frequency of the refreshes, and you are forbidding the widgets to refresh while the phone is asleep.

Do Not Rely On Battery Discharge Rate LINK
Look! Left it overnight and only lost 2%! This is about 0.25%/hr!
WRONG!
The battery acts like a capacitor (not exactly like it, but very similar to it), so whenever its charge is changed, the discharge / charge rate will change with it.
So, if you leave your phone overnight at 100%, you'll get a rate of x%/hr. If you leave it at 50%, you'll get a rate of y%/hr where x and y are very different.
It's only a matter of experimenting where is the sweet spot of battery percentage that you should have when keeping it overnight.

Do Not Wipe Battery Stats LINK
Some people do that a lot... but why?
What's Battery Stats?
Battery stats is basically a file in Android that stores the battery history. The longer the battery stats is, the more accurate the battery percentage reading is.
Why not wipe it?
Wiping battery stats is like tinkering with the fuel gauge in your car: you won't get more gas if you glue the gauge's needle at Full.
The problem is that wiping battery stats will give you wrong readings. Users thought that wiping it will make the battery "hold the charge better". This is wrong because doing so will break Android's battery reading, and that's why it will show you a higher percentage for a longer time.

Do Not Buy Cheap Batteries LINK
Wow! A 2500 mAh battery for my Galaxy Ace! And the same size of the original!
The problem here is that some users order a battery with a higher mAh value for a very low price. They get their 2500 mAh battery and put it in the phone. The device would last a lot longer now before its battery dies.
Now let's not forget why they ordered such a battery. It's most probably because their old battery is just exhausted and isn't lasting much. So no matter what battery they get, they'll notice a big difference in battery life.
Usually these cheap batteries are advertised as 2500 mAh, while they're actually a lot less.
So if you want to replace your old battery, try getting an original one.

Thanks to all of you who gave me more ideas on how to achieve better battery life
Medium
Undervolt LINK
The CPU is the biggest battery consumer, and it needs voltage from the battery. If we decrease that, we'll gain some battery life.
Undervolt your CPU
Assuming you have TricksterMOD, launch it and go to the specific window. Scroll down to CPU Voltages, then click Profile, and save the Profile as Default.
Now hit the minus/plus button right above where it now says "Default". When the window pops up, hit the minus button JUST ONCE. Every time you hit the minus button you undervolt by 12500 mV, and we'll call that a "step"; so undervolt by one step.
Hit the check mark button to apply.
Explanation
Every time you undervolt by a step, the CPU will demand less and less from the battery to run. This improves the battery by just a bit. It's mainly to avoid temperature throttling, but it also improves battery.

Increasing SD card Read-Ahead Value LINK
Whether or not you have an SD card, this helps...
Increase readahead Value
Go to TricksterMOD, swipe to general, and click Read Ahead Buffer Size under the I/O Control section. Set it to 3072 (Value is in KB, so it's 3MB)
Explanation
The bigger the read-ahead buffer is, the better the SDcard can predict what command would come next. It prepares itself to do a command before it's even issued. This gives you better performance, and a potential increase of battery life because generating 3MB is nothing compared to the performance benefit.
Check out this Spreadsheet from broodplank.net for more info on the benefits of read-ahead.

Advanced
Underclocking LINK
One major battery drainer is the CPU, so if you don't really use the phone much, and you don't care about games, you should probably consider underclocking it to get that precious juice back.
Requirements
You must be rooted and have a kernel that supports overclocking. You may find out how to root by doing a little online research because every device has its own rooting method (for example, I wrote a fully detailed guide on how to root your Nexus 4).
CPU Underclocking
Warning: Underclocking the CPU too much could result in an SOD (Sleep Of Death) which makes the phone sleep and not turn on without pulling the battery.
First of all, we need a controller, or a daemon to control the CPU's clock speeds. So go ahead and download TricksterMOD from the Play store, we'll be using that to underclock the CPU.
Now enter it and grant su permissions, swipe from left to right and select the general menu, scroll down to CPU frequency control and tick frequency lock, then click on the number next to the min button, and choose the smallest number in the list.
Then, click on the number next to the max button and choose something a little less than you CPU's stock frequency... on a Nexus 4, the stock frequency is 1.5 GHz (or 1512000) so I picked 1.2 GHz (or 1242000).
Now swipe down to CPU Governor Control and click the button next to the Governor Button, and select conservative. If you don't have conservative in the list, pick ondemand. Now hit the check mark button at the top of the app to apply the settings.
Explanation
We are lowering the CPU's clock speed which makes it a little slower, but consumes much less battery. We are also changing the way the frequencies are handled: with the conservative governor, the CPU will prefer staying at lower frequencies.
MP Decision
We're not done yet, swipe again from left to right and click specific, then look for MP Decision. If it's there, turn it off, if not then it's probably already off. Hit the check mark to apply the settings.
Explanation
MP Decision sees how you use the phone, and clocks the CPU relatively (if you're just chatting, it'll underclock. If you're playing games, it'll clock it to normal). We don't want that since we want to force underclock the CPU, so we turn this off to prevent it from playing with our settings.
GPU Underclocking
On that same screen, scroll down to GPU max frequency, and lower that just one step below the default clockspeed (400 MHz being the stock frequency on the Nexus 4, so let's set that to 320 MHz). Don't forget to hit the check mark button to apply the changes you've made.
Explanation
The GPU draws almost everything you see on the screen, so it's always active. Lowering its frequency has a big positive impact on battery life, which is what we want.
So that's basically it for the underclocking part, have fun playing with different governors and frequencies to get that precious Performance/Battery life point.

Detecting Wakelocks VS Installing Battery Saving Apps LINK
The most cliche thing to do when your battery doesn't last a day is install a battery saver app. However, I don't do it myself. I prefer detecting wakelocks in order to reduce battery consumption.
What is a Wakelock?
A wakelock is the moment where you turn the screen off, but the CPU stays awake doing something. It is the phenomenon when the CPU isn't asleep when the screen is off and it shouldn't be doing anything. Wakelocks usually drain battery because the CPU is kept awake and working while it should be resting.
Detecting a Wakelock
To detect a wakelock, install Wakelock Detector. Charge your phone, then unplug it and leave it with the screen turned off for about an hour or two. Then open the app and check the list of wakelocks.
The bigger the red bar on the top, the longer the wakelocks are. The top app is the number 1 culprit, and should be removed. If the top app is Google Services, it's probably the Location issue. If it's another app, check if there are syncing issues, and try making the sync interval a little longer, or turn off its notifications.
Explanation
We're trying to minimize the wakelocks caused by some apps to prevent the phone from being awakened. By doing that, we let the phone go to deep sleep faster, and longer. So, more battery life for us!
Another way to detect wakelocks (a little more pro)
Download and install betterbatterystats. It's basically a more pro version of Wakelock Detector. It also needs root for some functionality to work, but it gives you a more in-depth info about the wakelocks, CPU states, and network usage.
msm_hsic_host is the 3G... not to worry about that
So that's it for the wakelocks! Keep testing with different app configurations to achieve the best deep sleep mode for your phone, and get the most out of your battery.

Undervolt Even More! LINK
Undervolting once is fine. Undervolting twice is better. But undervolting a million times isn't good... So let's undervolt as much as we can.
Download Stability Test, run it, and hit the Scaling Stability Test button (root will be needed). Wait about 8 to 10 minutes while it's doing the process. If it doesn't crash, stop it by pressing the back button. Your phone is stable, you can undervolt even more.
So go to TricksterMOD and undervolt another step (remember to save a profile indicating how many steps you've undervolted). Then test again using stability test....
Keep doing that until something bad happens like the app crashing, or Android itself rebooting. When it does crash, "overvolt" back one step. At this point your CPU is running good while on the lowest voltage.
Explanation
Every time we undervolt by a step, we test the stability of the CPU so it doesn't crash. When it crashes, we overvolt back to the last voltage set that was stable, so that we get the lowest voltages our CPU can handle without going crazy, and thus, getting that slight push of the battery life.

Tweak Kernel Governors / Schedulers / KSM LINK
These tweaks only apply to certain kernels, since not all kernels allow you to modify these settings.
Governor, Schedulers, and KSM Tweaks
If you have a kernel tweaking app like tricksterMOD or faux clock, you are 90% free of all trouble of tweaking kernel governors.
First, find a kernel that has a specific and optimized governor. Turn off MPDecision if the kernel has an alternative (anything like "Intelli-Plug" will do). Now let's tweak!
We cannot cover the options for every kernel and every governor in the universe since each one has its own options and settings.
I am currently using faux kernel on my device. This kernel has intellidemand as the optimized governor. The aim of the kernel dev was to replace MPDecision with something better.
The links below provide some info about that kernel. These settings include tweaking the governor, schedulers and the KSM:
http://forum.xda-developers.com/nex...ernel-ver-031-mako-kk-4-4-uv-otg-cpu-t2008222 (the second post shows the recommended settings for faux kernel)
https://plus.google.com/+PaulReioux/posts/WFcjPqMEZgJ
Have fun tweaking!

Great guide, and great usage of your 2000th post! I've featured this on the XDA Portal
Great post!
I like using Screebl to prevent screen turning off and on unnecessarily. And use One Power Guard by onexuan. It really lessens the drain over night. I use Condi to automatically disable mobile data when connected to wifi at home as well.
very great guide! Just note something for people with HTC Sense. If you use the weather clock with current sensor, setting the location to GPS only will disable the location service (even if it's seems on, the widget will say it's off since it doesn't want to use the GPS). Because of that, you loose that feature if you do that.
Um, there's a problem with this guide. Instead of underclocking, overclock the processor. The faster the processor, the faster it gets jobs done, the faster it can go to sleep. These reduces long wakelocks and in general improves battery life.
I used to think the same way, but thinking that way is false.
What about Greenify?
idk about you, but greenify is useful.
EDIT: And for the fast charge/slow charge, do you have any proof?

So you're saying that it's better not to underclock and just use default values?
Hmm kind of skeptical about the home button thing. I usually back out of an app to prevent it from running in the background and consuming battery. Can anyone comment on this?

the fact that the app opens from scratch again makes the CPU work more and thus using more battery
if it's kept in the RAM, it'll stay paused, it won't use the CPU and makes your phone faster sincr it resumes the app, thus making your battery usage less.

you have a point if the user is a heavy user. But for normal users, the CPU won't be doing much; so underclocking it won't affect time, but it greatly improves battery life.

greenify freezes the app if you're not using it, so the phone will start it from scratch... it's a good app if you use it on apps that you barely use, but don't greenify the apps that you use frequently, it will badly affect your battery life.
as for the fast/slow charge, I have no proof since this is what i usually have as a personal experience, but i find out that my battery lasts longer when i charge it slower...

ah, you see, here's where it does make the good difference, keep doing that because you won't use the apps for about 8 hours, so it's better if they're closed.
i just posted this because i see people constantly closong the apps that they always use, but if you're not using the apps much (like when sleeping) it's better to kill them

First of all thanks! battery life is a never ending issue in any smartphone using the no animations, less widgets and device only location... hope it'll prove useful
I got a question... I use go power master which has a "screen off optimization" and i noticed that my battery barely drains itself while the phone is idle... it's not what you count as a task killer right?
I ask for an opinion to experts.
I installed the app Battery Life Repair
https://play.google.com/store/apps/details?id=com.BoshBashStudios.batterydoctorrepair
I can't understand if this app is really effective or if it is a fake. In both cases, if you want to give your opinion can you justify it with technical considerations?
It's strange to see so many high ratings, but it is also strange that there are no tests or in-depth reviews.
Sorry for bringing a thread from the dead but I am also very curious as to how this app works (or if it does at all).
Such apps don't work.. They're usually fake and earn money through ads. Battery life is purely hardware and can't be increased by a software other than changing kernel features...

what a load of crap.
You can increase the length of your battery time betweeen charges by lessening the load on the cpu(which causes ups in voltage usage).
we reduce cpu load by reducing ram usage too.
also, turning the display brightness down and turning off unneeded features like bluetooth or wifi.
the kernel can be made more efficient like you said. so i agree there.

Trying to do that the battery app takes more battery by being in the background always. sometimes it also steals data.. There's no point you're better of without it.

Of course the battery does nothing.
thats what the settings > battery
function is for anyways. to see the resource hog of the system.
so it works in identifiying the problem.
but your right, the battery app is unnecessary since we already have a stock implementation.
but that wasn't my point. my point is that you can modify the userspace for more battery between charges.

At the end of day we agree that battery apps are not required... Android is pretty optimized by itself.
Decrease screen brightness and timeout it takes the highest amount of battery.

"At the end of day we agree that battery apps are not required.." obviously.
"Android is pretty optimized by itself. " its not about android(I didnt mention android being optimized, I figured that it was pretty obvious and didnt need discussion), it was about android having the tools to find the problem. see the following:
"Decrease screen brightness and timeout it takes the highest amount of battery. "and this brings me to MY POINT.
We are talking about app hogs which ARE a problem.
I would expect the OP has enough of a brain to reduce the brightness.
You have app services that use tons of ram and cpu. Why can't you accept that?
The theory behind a battery app is legitimate, but the OP just has to use the builtin android application.

Confrontation Much
The original posting he said was that software does not have impact on hardware in that it can not fix physical damage on the battery such as dead cells.
Such apps are just fake.
I purchased a new phone and same day I installed repair battery life. It showed 8 low cells and one inactive. It claimed it will increase my battery life by 18% (WOW, LOL)
After that I tried again and it showed me all green cells.
I cleared the app's cache, cleared data and uninstalled the app.
Later on, I calibrated the battery with another app called "battery fix" which needs root and deletes batterystats.bin file
I once installed "repair battery life" and guess what? It showed again 8 low cells and one inactive.
It's just another fake crAPP
Number of cells shown suggests fake.
I tried Battery Life Repair by "Extended Apps " and I remain very sceptical. Nowhere it is explained what the app actually does.
A normal Phone has one or two cells. This app shows 100 cells and claims that some are broken or damaged and the software can repair it through some extraordinary (supernatural?) process. It Claims it repaired these problematic cells (like 5 out of 100), although it physically makes no sense considering a phone has one or two cells, which are usually either working or broken. Then it also requests access to media, identity and accounts, which is suspicious given what the app claims to do.
Comments in the app-store just prove to me that placebos work. On the other hand, some people figured that if the "battery repair" is done, the app data is deleted and the app run again, it again shows the same amount of "problematic cells".

I strongly suspected myself this app is complete bull twaddle, but I was also curious so installed it just to see what it makes of the battery "analysis".
It magically 'fixed' the problem cells, but unlike you on a subsequent retest the previously 'faulty cells' had still be 'fixed'.
I wonder how this app is polling the 'cells'? Or is it just making up some fancy graphics and not actually doing anything at all under the hood?
I also wonder what would happen if I switched batteries or took the existing one out and in again? Maybe I'll try at some point.
This is my experience.
I thought this is impossible but i installed it just to try..
In that time i first tryed it i had Galaxy 3 Apollo. Battery was so bad that percentage was going low when you were looking on it and after some short period of time phone just shutdown by itself.. I decided to try it so maybe i save money for new battery. With few shutdowns i finally did it and something happen. Battery didn't go low that way and phone stoped turning off by itself!! It could stop while i was washing dishes but it was "fixed" after i used that app, so i dont know. I don't personally think that some app can fix hardware issue but i think it works as some "refresh" or something like that. I don't know really but in my case was money saver what ever that is. Oh and i'm talking about "Extended Apps" app.. :/
I'm also skeptical about these things but unlike others in here, I tried before drawing conclusion with my awesome rational brain. And yes it works marvelous. My Galaxy Note 3 battery is working as brand new, giving 3 to 4 days without charging and it was 1 to 2 days before the app. I don't think that is placebo effect and I have absolutely no idea what the app does, and too bad the dev doesn't have a website, but the app is good. Also using the other app from the same dev, called Advanced Battery Calibrator and letting the phone charge till 100% while off did wonderful things.
I still wonder how it can fix hardware of it simply erase data from the battery increasing risk to catch on fire, but it does work.
As far as I know, the software keeps data of the battery in other to avoid charges over 100%. With time that will effectively make the battery charge till 99% then 98% and goes on, till u have a battery on 70% for example but the software say its 100%, because it wont charge more than that to avoid the risk of fire. Perhaps this app erase that data and increase the risk of mal function. But I have no idea.

If your battery has dead cells im sorry but no app will fix it, unless its magic! It must replace the cells somehow magically! Omg do some basic research these apps are fake garbage! Maybe it can fix my dead s3 battery hahaha NOT!

ofc is not gona revive a battery,but even that it can be made,in some cases,i saw that of ppl proving that live,they took a dead battery and test it to show that it is dead and just used another same model battery that it was working and hold them connected like 5 min toghether,after that it just put the dead battery at charged and what u know?it did revived it,no idea how the battery actually work,but it seems that they can actually get stuck somehow and they can get a "forced" revive,like a CPR for humans,but like i said,not working with all,same as like on humans,not all can be revived with CPR,but i guess that this app has to do something coz like some in here i did used it and ... the magic worked,not on a dead battery,so scheptical as it sounds,on some batteries it works even tho maybe is not something hardware but maybe just something software,why i say that,i had a tablet and a few times when i was restarting the tablet,after a min was turning off coz of battery 0%,and that after i got the recharger plug off,so it was 100% for sure,after a few times restarting the tablet it was showing again 100 % as it should be,so i guess that not even android is always reading the data correctly
Of course is a full fake. Uninstall them, becouse they can do bitcoin mining or whatever gain trough pupup and promotions., as well as getting your data.
1) Ion litium or polymer batteries cannot be repaired.
2) cells are 1 or max 4 not 256 as those apps shows
3) clearing the cache brings different fault cells
4) reinastalling shows other broken cells
5) strangely the application after "repair" stays open in background. So at least the word "repair" is a joke fooling people.
6) dynamic ram and ddr are always powered and refresh cycles are required in all the address space generally, so saying that freeing ram allow more battery duration is a fake.
7) whatever the app does to have battery least more is just sw and tricky. I would not rely on that and remove the app.
Wow...

Didnt notice this was my brothers account he uses my phone
Hello, there's a way to calibrate your battery without root.
to calibrate your battery, i found by my self a way to(when i did it, the battery time left was increased):
1)charge your phone to 100% battery.
2)turn on- wifi, auto rotation, bluetooth...(everything that is consuming battery not including apps)
3)leave your phone with screen off.
4)discharge much as you can.
5)when you finished, charge your phone and don't use the phone.
optional:
if you want a proof that this is worked- open settings and see how much time left for your battery(you will see that it had been increased).
FYI I just finished testing Battery Life Repair 2018 by running it on a new Android tablet with a huge 8000+mAh battery. It reported about 14 weak or bad cells out of a total of 120 cells. When told to fix those cells, it requests you to download another of their apps to help support them. Just say YES, then kick back out without downloading and the fix finishes. I had hardware "USB Safety Tester" connected during this test (it displays various info including the charging voltage and amperage). With about 12% of the cells reported bad, after the fix the Tester recorded zero increase in Volts or Amps. So it maintained a steady watt draw from the charger even after 14 more cells were now drawing watts to charge. Next I cleared storage on the app, ran it again, and got 12 different cells reported to have problems. Fixed those cells, and again, no change in charge draw.
I also found it strange that it would use WIFI and Cell Data and run in the background. Why?
The Battery Life Repair app reports that my Galaxy S5 also has 120 cells in its battery. Seeing as almost 99% of phones and tables have a SINGLE cell in their battery (one or two phones have 2 cells), the display of a 120 cell grid seems rather fishy. Having a 120 cell battery requires cell balancing hardware and software that that would add to the cost of the phone, plus make the battery physically larger. My electric bike has about 80-90 cells in it and it weighs about 15lbs and is 30,000 mAh and 47 volts. Hard to do in one or two cells. That is a good example of why a multi cell (3.6 v each?) battery is needed. But not a cell phone or tablet.
I know my test is not the most scientific, but at least I did check for a change in wattage draw before and after fixing cells, and not just ecstatically claim my battery has improved.
So I call Battery Repair Life 2018 to be a steaming pile of BS that is probably robbing you of your contacts and other personal information while running in the background sucking up your data plan. But, hey, that's just me.
I want to know how everyone else uses their phone because people that call and text all day with minimal display settings might get decent battery life out of the battery in the Note 8, but I am finding that the way I use the phone..... Multiple email accounts, some android games here and there, various IT Tools to make sure people at work aren't connecting un-authorized devices to the network, etc. Basically I am using my phone all day.
And I am not able to keep the phone plugged into a charger all day. Then I will get responses like use the wireless charger. Well wireless charging is wonderful if you don't need a charged phone with you at all times. Wireless charging is slow and the phone still needs to be on the wireless charging pad. Not on me or in my hand all day. All wireless charging does is keep people from damaging the USB port by yanking the charging cable.
So in my case this battery thing is becoming a serious problem.
How do you use your phone and is the battery fine for what you do?
I am on web sites, playing games, listening to Pandora, messaging, and a few phone calls, some email, and downloading apps. Usually get over 24 hours a charge and over 5 hrs of screen on time.
I dont play any games, mainly forums and websites and news apps, BBC, RT, Press etc I dont watch youtube on it either much. I get 7 hours screen on time, wifi, bluetooth, AOD off.Also some bloat disabled. USA TMO version. black wallpapers also.

I'm constantly using my phone throughout the day for both work and personal. Have my exchange email setup to push notifications (I get a lot of emails) and gmail synced. All my social media accounts (FB, IG, Snap, Twitter) are synced as well. I can usually get through the whole day before charging the phone to 100% before bed around 11pm then taking off the charger. Depending on if you use the features you may want to turn off features that require a sensor. Since I'm not sure what exactly your setting are, here's how mines setup:
- At work, wifi-off and bluetooth on. At home bluetooth off, wifi-on
- location is high accuracy all the time
- AOD is on from 7am-11pm
- I have "block accidental touches" on which turns off AOD when in pocket, etc.
- I have edge panels on but edge lighting off
- turn off "nearby device scanning"
- In advanced features, I have the following settings off since I don't use (and could help batter since they require a sensor to activate): smart stay, direct call, smart alert, easy mute,
There's probably others I'm missing but I recommend going through each and every setting in the menu including sub-menus and looking over everything. You'd be surprised how many different settings there are and features that you may never use that could be using up some juice. Hope this helps!

Interesting observation, aod ON in conjunction with accidental touch ON with my leather folio wallet case that I use ( edge clock ) works a treat as it shuts down the aod when I close the case.
I noticed this as I was telling my wife she should turn her AOD off as she has a wallet case also, she duly told me to bugger off.

I've had no luck in improving my battery life until I enabled Data Saver (Settings > Connections > Data Usage). I went in and enabled a few apps I wanted to run in the background but overall didn't need much enabled. I went from 16hr on battery, 3.5hr SOT to about 28hr, 5hr SOT
Battery life has been pretty good but you have to control how some apps work when you're not near a charger.
The biggest battery drains are obviously the screen but often overlooked is data sync.
If you're using your phone to take pictures syncing with Dropbox, One Drive, Google Photos really can drain the battery quickly.
If I'm out and about without a charger I shut off automatic sync and might use the Mid power saving settings and haven't had problems 10+ hours.

Thanks for the suggestions Some of them, I will try, but others, I am not willing to give up. Things like full resolution display; Yes I can lower the screen resolution to save power, but shutting features off like leave me with, well, something that is not a Note 8. I would have stuck with my Note 3 if the display wasn't important. I use bluetooth all the time, wifi, not so much and never use NFC so I can shut 2 of the 3 antenna's off. AOD is on, and accidental touches is on.
Go into the battery settings and see which apps are using the most battery. Most apps sync and depending on how often and how much data can affect battery life. Putting some apps to sleep can really help.
T-Mobile sometimes suffers from weak cell signals, when that happens it can really be a battery hog.
It's a learning process on finding the right balance for your usage and battery life.

I started using Naptime and 2 days of battery on a single charge on the 1st day since then it has been pretty steady. As of now at midnight my battery is at 54 percent and I have been using the phone all day.
My battery life
I have always had 2-3 hours of SoT until I did 2 things. I deleted the FB app and started using the mobile site and I installed accubattery. This was my usage today....Keep in Mind, I have accubattery tell me my phone is fully charged when it hits 80% to save battery cycles. I did plug the phone into my laptop to transfer the pictures over to it hence the blip at the end but it was just long enough to copy the photos, upload them to tinypic and post, etc.
Definitely missing the battery life from my mate 9. Gonna take awhile to get used to that. Only had the phone for a few days, so hoping it settles in more.

Hello,
I got a battery issue on my Samsung Galaxy Core Prime for at least more than a year.
The problem is: almost everytime, my phone crash when arround 40% battery level. It's not an informatic crash but... I'm not sure. The phone just suddenly shut down, not as it ran out of battery, displaying the shutdown logo and going to sleep, it behave like I pulled off the battery.
This is not a battery misplacement problem because the shutdown doesn't happen a totally random way: it never triggered over 50% for now.
Moreover, the battery level goes wrong after such crash. Even after waiting some time with battery out of phone I got randomly a new battery percentage that will be either lower, same or even higher than when it crashed. So maybe the whole problem is due to a shift between real battery percentage and what phone determined.
I also noticed that when rebooting after the crash the phone speakers make a weird sound, a kind of "shhhhhhhh" even with silent mode enabled and no system sound, and when it happens phone recrash on booting (system) logo.
I personally don't think it's system's fault, because between the first time it happened and now I may have flashed at least 6 times my ROM and made various wipes. Also somebody getting the same phone model than me never got such problem, even tough he is not rooted and has recent firmware. In the end the problem getting worse and worse again (=more frequent) so I'm almost sure it's a material problem.
But which one? Is this directly battery's fault or is it captor's fault? Actually I threatened the battery very badly, it's true. But everything I did — overcharging, emptying battery at the time I thought that was a good thing because of a suppoesed memory effect like nickel batteries, using charger block from an older device with a bit different configuration — should have shortened the battery's life, however it's just like the battery is now discharging a bit faster but got a kind of danger zone where you're not sure that it will keep behaving normally, so much that some measurements and developing apps determined that my battery have a good health, that is maybe absolutely FALSE.
Talking about this danger zone, I also noticed something even stranger over all.
Depending of what I do, I got higher or lower chance to have my phone crashing under 40% level:
- If Wifi is enabled, the phone got arround a half more chance to shut down unexpectedly.
- This is worse when using data consuming app (i.e. Youtube)
- Using more hardware also increase this phenomenon (when using camera) and enabling flash instantaneously and almost everytime crash the phone.
Here are what I reported.
What do you think?
It has happened to me many times. So i normally keep it charging all the time to be safe.

All the time for real? Be careful, that's not a good practice. Unless you removed the battery first, this will get worse if you do that.
I have a similar but possibly unrelated problem.
If i charge upto 100%, the battery goes directly to 0 after around 50%.
If i charge upto 50%, then the battery drains rapidly after around 20%.
I don't think its a battery problem because its the same with two replacement batteries and a stock battery. (Or maybe I have a bad luck and bought ****ty batteries)
Will post a screenshot soon...
I have the Same problem i changed the battery twice but i still have the issue

This is weird that after buying two more batteries the issue still occure...

My device goes at 60%, 40%, etc. and then it starts repedeatly pressing the right side of my screen and not letting me tap the screen, so I lock it and unlock it very fast and I can use the touchscreen for a few moments, before it shuts down without the shutdown screen and makes a *tick* sound, almost like there was an electrical shock inside the battery. I have a PRF and TWRP 2.8.7.0.

Got exactly the same problem. You can try to change the battery but in my opinion the only good solution would be to buy another phone. This is personally what I did, as this model gets old really early.

I have this same exact problem and the only fixes according to me is to buy a new phone or replace the battery. Also I noticed that the battery of my device has bulged.
RIP, I have the SM-G360T1, stock based custom ROM with TWRP 3.0.1 and this thing's started to give up. Same issues as the people above encountered. The phantom touches are getting wayyy more repetitive, the battery all of a sudden goes down to an extremely low percentage, even at medium to high percentages (such as 50-60%) and even shuts off without any notification. I also had cases where the phone would completely turn off with no shutdown animation AT ALL, plus a spontaneous but audible *TICK* that follows it. Device performance in general also started to horribly depreciate.
Well, to be fair, I had this device for 3 years and I guess it had its day. Time to upgrade.
My device has started to shut off at 80% battery levels and even worse the device gives just about 25-30 min of SOT. Also stressing the device in any way.. games, YouTube et al just causes it to shut down. I now permanently have a battery pack connected to it at all times. But even after all this, the gives good standby time. Notably the device stand for 3+hrs on 3% battery.
Still my phone is in a pathetic condition. ?
Edit - I just got a new battery (aftermarket brand though) and the ghost touches along with sudden shutdown has gone. Also the OG battery was never touching the connectors properly or the battery placement design was not proper, cause the new aftermarket battery was not connected to the connectors properly.
Peace ?
i also got this problem on my sm-g360HU , try chaging different roms and buying a new battery pack, but still this sudden drain battery still exist, it seems like it's the hardware problem already.
When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the OnePlus 8 Pro's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
Most my phone's besides my Huawei Nexus 6P have all lost 0-1% overnight.
Even with tweaking I can only manage at best 1-2% which I know compared to other users is excellent but it's definitely worse than my previous phones.
Without tweaking for stamina and good hibernation the device uses about 2-10% depending on what's installed, which wasn't any difference to previous devices (app wise)
I'm happy with it, I'll keep tweaking and see if I can hit that magic 0%

Any tweaking tips? I've turned off 5G and that helped quite a bit.

Change 5G to 4G
Remove Facebook use web based
Remove Facebook messenger use web based
Remove Twitter use web based
Remove any ad based apps pay for the pro version
Turn off gestures like lift to wake
Change from QHD to FHD (No difference)
Allow auto brightness
Turn off WiFi overnight
Turn all updates to manual not auto (play store)
Remove any so you don't use
Change back up to once a month (WhatsApp)
Turn off location history (Google)
Use titanium to remove any system apps you don't need
Don't allow anonymous usage statistics for any app ever.
Don't allow tracking cookies on any website
Use adaway (root needed)
Don't open web pages in Google app (I use Samsung browser)
Don't use xposed.
If you game you will not get high SOT scores, period.
Don't bother with battery saving apps or monitoring apps.
Streamline your apps, if you don't use it, remove it.
Don't allow WiFi scanning (as in letting other apps use it when it's not on)
Never allow personalised ads.
Never allow notifications from websites
Always decline cookies unless your absolutely have to allow some tracking (common sense prevails here)
Optimise as many apps as possible unless it affects performance.
Don't allow apps to remain open in the notification area.
Change your launcher, my preferred launcher is lawn chair and this did actually burn up some battery when compared to the OnePlus launcher.
Don't use live widgets (yes they look cool, but they annihilate your battery)
Live wallpaper, again very cool, but battery burners.
Again! Don't charge overnight, make a note of your percentage then see what it is in the morning, you shouldn't be losing more than 5% really, if you've done well then it'll be reflected here, the good SOT results will follow.
Turn off live read outs of network speed, RAM usage in the status bar.
Turn off NFC unless in use.
Leave location on in quick settings.
Don't overcharge your phone, IE: overnight
Don't allow your phone to fully deplete the battery.
Whatever anyone says, this does 100% damage batteries, there is no argument here and I won't entertain anyone who says otherwise, Ive seen through real life tests what this results in, bloated, inefficient, possibly dangerous lithium batteries.
Keep your phone out the sun.
Keep it out of extreme cold.
Keep your device clean dust free.
Snapchat, Viber, house party, apps like that tends to use more battery as they don't have great dormancy periods.
Apps like speed test by Ookla tend to have location tracking, similarly they tend to turn themselves on and off when they feel like it, my advice, install test and uninstall.
Allow a couple of battery cycles between tweaking sets, to give you an idea of how much of a difference you've made.
Use BBS to see what is being used, once you've removed problems, remove BBS.
I've just written this from the top of my head so o probably missed some things, the general idea is to keep your device clean and fresh, remove files you don't need any more.
Keep an eye on apps that misbehave or aren't wanted, index your folders so they aren't a mess.
The more good things you do means the more potentially bad apps you can have on your phone, eg if you really need Facebook, you could keep it so long as you clean up other areas of your phone.
Good luck.

Cracking game though, I find android 11 open beta 1 charges really slow on a normal charger that's my only gripe with it, but battery is wow
I have a great screen on % ~13%h.
But standby sucks.
I also have removed/disabled stock apps, location of, only enable it when I use it, same with Bluetooth. But I still have 1-3% standby /h. Over night I loose 2-5 % and the same again right after I wake up and use it..
My standby time was so bad 3-4%h, that I rooted it and change doze with an app.
3% h over an day (12h) makes up 36% battery uses. Just laying in your pocket and doing nothing... That would be ~3h screen time.
Still can not get the standby time to 1% what it actually should be!

I'd look in alarms / wakelocks for the cause of your battery drain.
I have more like 0,7% / hr standby, 1,5-2% over night.
Uninstalling Facebook and Messenger would probably take me to 0,5 / hr and 1,5% overnight. This app is a f**** disaster, but unfortunately it's required in my company (Fb groups).

Wake gestures, like lift to wake.. Keeps the phone from sleeping..
Also don't worry about location, maintaining a location is now efficient than obtaining it for all apps in one hit.
I've never turned location off besides for Google, I pause location history, far too creepy.
I have no facebook, instagram or messenger, the only social apps I have are telegram and snapchat.
I use betterbatterystats but there is just no app that keeps the phone awak all the time. I have no f*** idea why it sucks so hard.
It's super annoying.
Android 11, drain is worse, SOT is worse and I've changed nothing compared to android 10.
Disappointing to say the least.

How's yours now?
I've just sent through all my apps and optimized all the ones I don't need running at full chat, also deleted some apps that may have been causing issues.
At the moment it's looking ok
3 hours up
1 hours SOT
92%
That's heading for 10 hours if I'm not mistaken, so may have been one of my apps or poor optimization on the phones part..
I'll keep an eye on it, have Gsam running as BBS simply wouldn't accept I'd granted app_ops permission?
Maybe an android 11 thing.

It's 120hz FHD. I honestly can't see much of a difference between QHD and FHD so taking a battery hit doesn't seem worth it.
I'm currently heading for 12 hours here. Have just been using XDA and watching some videos. No gaming today, WhatsApp and telegram.

I'm running blu-spark. Never used it before but it's idle performance is brilliant.
Very impressed. Also extremely low clocks 300mhz
Great tips from many members. My phone drains very minimally while standby.
