So, I made a switch from HD2 running android to Amaze hoping it will have a better battery life coz of its juicy more 1730mAh battery, more power efficient s-lcd screen and the fact its an native android device (which the hd2 wasn't) but its been barely 2 days and I'm seriously disappointed with it.
I'm have a moderate usage which includes calls, pandora, youtube and net surfing but it barely lasts till evening and the usage is actually less than what i did on HD2 coz I don't have put any games on Amaze yet. I had lots on HD2. With HD2 I could easily pass through the day and still have about 10-20% battery left at night and this was on its anemic 1230mAh battery
I do realize the HD2 was rooted and was running CM7 and had all kinds of custom kernels and stuff. So is stock Sense and HTC kernel the culprit here ?
I've already ticked in the setting for Power efficiency under power settings which turns off auto sync (I have google and facebook sync same as I had on HD2) and using auto brightness with the least setting, but neither of them are helping
One thing I noticed in current widget log and current widget display, is the power drain in standby hardly goes below 100mA anytime ? According to me, this seems to be the issue hogging the battery as on HD2 it used to be <10mA most of the times with occasional spikes...but in Amaze every value is like more than 100mA. Does the faux kernel and custom ROMS helps with this, a lot ?
Ideally I should try it myself and see, but don't want to unlock the bootloader and stuff just yet as if the things are going to be like this, I may as well sell it and put in some more money and switch to other side (sgs2)
The other theory I have is the CPU on HD2 is single core 1GHZ while Amaze is dual core 1.5ghz. Gingerbread doesn't have proper dual core support so things will improve when ICS comes ?
Also on a side note, is there a problem with earphones having L shaped jack on Amaze ? My primary headphones monster turbine pro which have L shaped jack don't have a very good fit in it and small amount of force seems to disconnect the headset from phone. Its really annoying, although my other earphones which have a straight pin don't have this issue. But its not the earphone problem either as I don't have this issue with turbine's in my mp3 player and HD2 ?
The stock battery was horrific for me so I bought the Anker 1900mah battery from ebay and It's far better than stock...I'm at 15 hours with 47% left...Tasker is helping a lil also.

Hmmm didn't think i would have to upgrade the battery just after buying it, although seems something wrong is with the battery though...maybe HTC just bloated its spec to 1730
Yea, I have advanced task manager with auto-kill, but its really the same with it or without..

Try letting the battery discharge completely until phone turns off, and then plug it up and let it charge to 100% without unplugging it.
My stock battery last 12-16hrs depending on use. I also have an Anker 1900mAH last a good 18-20 if I charge it inside the phone. If I charge it with the Anker charger it last about 8hrs.
Guys what about the current widget numbers ? Have anyone of you got it or can get it to see how is the drain like for you guys?
No matter how strong the battery, if its going to [email protected], it won't last very long. 18-19 hrs on after market 1900mAh battery isn't very impressive figure either
I'm not quite sure of this drain, is the fast 4g on Amaze the culprit just like LTE
Also let me know if you guys have stock or custom ROM ?

i assume youre talking about cell standby? you WANT this number to be high on the list
You should use a battery saving app like juice defender or battery fu.
Personally, I use battery fu and I have gotten more than 20 hours of battery, on stock battery, running on stock phone, unrooted.

I havent had any battery life issues with mine. Before rooting I could go the whole day on a charge but it would be close to dead around 10PM. I'm still getting used to the new ROM I flashed but battery life has definitely improved.
I would recommend opening the task manager and killing off some unneeded apps.

Is it bad if I use the HTC task manager, I only use it to kill the browser which stays open even if you hit back

Using task managers to kill an app that you don't want running isn't bad, I think its the continuely killing all apps every 30 minutes that makes it worse.

I'm not sure why this should be high
It should be low ? A high number would mean its losing more power during standby...
Guys, There are 2 school of thoughts about task manager...I agree task manager may consume more battery if you look into the theory how android works...but I've tried with and without task manager it doesn't make much of a difference from what I observed
Also what about L shaped jack earphone issue? Is it fine for everyone else?
I have the same issue my battery lasts 6-8 hours MAX with intermediate use....juice defender, tried every rom and different kernels.
My brother Easily gets 16-18 hours with intermediate use (galaxy s2) same processor. I know his battery is a little bigger but I didn't think his battery life would triple mine -__-

Hi Glacier,
Thanks for the update That seems reassuring...
I've been researching on Amaze battery quite a lot, I think current widget numbers are misleading because even in Airport mode it shows more than 100mAh drain, which is not possible..
I've found out another app...My battery drain analyzer written by a fellow member here at XDA
https://play.google.com/store/apps/details?id=com.WazaBe.android.BatteryDrain
It basically calculates the drain rate in %/hr, basically measures how much time does it take for battery to take 1% dip...
I've found for my amaze its close to 1.6-3%/Hr when in standby, when phone is not woken up during the period...I think its on a higher side but acceptable still...Can any member with a custom ROM/kernel also report his/her number..
BTW I've seen the numbers on TMO SGSII in their forum, this number is roughly the same there too ~ 2%/per hour for most users...
you guys might think i'm crazy for asking this but i think there is an option is STweeks in Siyah's kernel. I'm only asking those who just use their phone for daily usage and not for heavy game playing (i am one of those). Just wondering what the experiences are and if battery life increased much. As of now the battery life is great for me, without turning any cores off.
On that note, i know there is a S3 version with 2 cores with 2gb of ram.
Personally I wouldn't expect it to make any noticeable difference, but Samsung's power management should do this anyway for normal usage, and you may find intensive tasks take longer actually adversely affecting your battery life.

hey, so i have ran pretty much every "jelly bean" rom out there for this phone for about 2-2.5 months. maybe less. note sure..
anyway, the battery has been horrible! on every rom.. I have a 2700 mAMP battery, and a regular Samsung battery. I have to use both once a day for this phone.. now I have no idea what is making the phone loose percentage after percentage of battery as fast as it has for me, but everytime i post i get about 0 luck from people that either have the same issue, or just people saying they have heard it a million times. i probably should have put this in the "Q&A" thread, but maybe i forgot. can someone, preferably more than one, help me out here?? i don't get how other people say they have 8 or more hours of screen on time with half the battery left. it just doesn't make since. I am loving the android system. but this could be anything! the apps in the background. the kernel, maybe I didn't clean my cache or something. i can't raise my brightness up to far or it'll drain my battery, jamie in the paranoid thread said he had his batter on 100 percent and had excellent battery. so I'm far from confused here. do I need to get another phone, or what. very much apprentice the help from as many people as possible. I love my phone, but I hate that i have to focus on using two battery a day with this phone.
Same here battery draining pretty quick on all jb ROMs.

Battery usage is highly subjective..
It's nearly impossible to determine a baseline Usage expectancy, simply due to the untold number of variables that drain the battery.
We know the obvious power users ....the display, wifi, data ..
But it gets far more difficult to track the Usage after that.
We know that JB is not optimized for our device, but it's getting better, and until we see a true JB kernel with the rom matched to it, the battery is going to suffer.
Then of course we have the many services that users run, along with countless apps ...
Long story short ....maybe a more stable choice would work better? ?
Like ICS, At least until JB calms down a bit ...
I'm actually running Saurom as I type this ...and my battery life is excellent.
JB just isn't quite there yet ...IMHO ....g
to get better battery turn brightness to lowest usable setting, turn off sync for any non essential apps, turn off soft key lights, flash a kernel that lets you under volt and under clock, try different govonors and io schedulers, turn off gps, put in airplane mode when not using. these should help. keep in mind cell signal strength will also impact battery and 4g will kill it faster then 3g. i am on cm9 stable under clocked to 1.18 undervolt all by 25mv( not much change but i like to be safe) ondemand and sio and get amazing battery life.
What's your screen-on time? 4 hours is the close to the limit on ANY rom for our Notes. You have to make sure it's not some sort of confirmation bias going on here.

thank you so much man! i actually went to at&t and they mentioned that too. they said the kernel im using isn't fully optimized for the phone yet. other words. the phone wont support it. he said basic stock ics is the best thing to do now. he also said. these forums are for phones from Europe as well. not just for AT&T in the us. again, the ROMS these devs are making are not supported for the phone, and is kinda like a mimic of something its not. he said jelly bean was out, but i don't know where to get it. can someone tell me how to install ICS, because when I download it, and use KIES, it installs the system, but never fully completes the process.

Battery life is purely subjective. No two people will have the same experience.
Have you used an app like CPU spy to make sure the phone is going into deep sleep? Rogue apps keeping the phone in a wake lock can seriously affect battery life, but its hard to say if anybody's apps are doing that, because we all use different apps and there's no list of apps that keep a wake lock, so you need to use something like CPU spy to see if you are going to deep sleep when your screen is off.
Related to apps as well, don't use any task killers or constantly kill apps when you exit them. A lot of people think killing apps is necessary when it completely is not. Android, since donut or eclair, manages its RAM very well, so that when a properly written app (ie. It's not keeping a wake lock) is in RAM, it's just in a frozen state not using any CPU cycles. Constantly killing well written apps hurts battery life, because restarting the app fresh is much more processor intensive than pulling a frozen app out of RAM. Plus you don't have to deal with annoying loading/splash screens.
Also, like others have said, using the lowest brightness possible, and turning off sync for any unnecessary apps will help battery life. GPS doesn't matter so long as you don't keep something running that uses it. If an app isn't using GPS, then GPS isn't using battery. I always leave my GPS on and do not notice a difference compared to turning it off. If you're paranoid about GPS leave it off, but it's annoying to have to turn it on every time you want to use an app that requires it. You can also disable location access in most apps like Facebook, twitter, etc where you don't need GPS really, and that will make leaving it on even better. If you don't use GPS much anyways, leave it off.
Like somebody said, your cell signal can greatly affect your performance, so use WiFi whenever possible, and even put a data toggle in your pulldown so you can disable cell data when you don't really need it. WiFi in general uses less battery than cellular data, so I use it whenever possible.
I've also noticed that how you use your screen on time also has a great effect on battery life. When I have extended lengths of constant screen on time where the phone starts heating up and whatnot, I see much less battery life than if I just use my phone here and there intermittently. Long stretches of screen on time stress the processor and battery heating them up and making them less efficient, where as short stretches allow the processor time to stay at a cooler, more efficient temperature. If you game at all on your phone, you've definitely experienced this, as you know that your phone heats up due to the extended lengths of screen on time and heavy processor usage. Gaming is a no-no if you're striving for better battery life.
With following those guidelines, my Note sees about 3.5 screen on time with JB on Gubment Cheeze. I would get around that on ICS as well, and I don't remember what it was on GB. Fellow testers and teammates for Gubment Cheeze have seen up to 4 hours and a little more even on JB, so it's definitely possible to have decent battery life on JB.
It really comes down to your own personal usage.

I was not aware of this info....many thanks for the heads up...I always supposed that since the ram was consumed with applications, that those apps were pulling CPU usage from the device...
that is clearly not the case......g
Yep, no problem. If you go back to a touchwiz based ROM and go into the stock task manager, it shows you what's taking up RAM, as well as the CPU usage of each thing in the list. If the apps are working properly, pretty much everything will show very little to 0% CPU usage, and ones that are using it heavily will even be highlighted in yellow or red depending on their CPU usage %age. Unfortunately aosp based ROMs don't have that task manager, one of the things I miss from touchwiz.
Every time a non-techy friend buys a new android, it seems the overly aggressive sales rep that sold the phone to them 'helped' them get to know the phone and installed a task killer, specifically advanced task killer. I always just uninstall it without telling them and see how long it takes them to notice lol.
It's still useful in certain instances, for example if you have an app that doesn't run well but you still like/need to use, but in general practice android does a much better job of managing itself. Besides, if you have an app that you know runs poorly and hogs your processor in the background, but you still need to use it, with most aosp based ROMs you can set your phone so that long pressing the back button kills the current app, essentially making task killers useless.

This is true. What kind of signal strength do you get where you are at? Does your phone bounce back and forth to lte. I have noticed when i go from a strong signal to weaker signals or band switching a lot, my battery drains rapidly.
Use cpuspy, as mentioned, to verify you do see deep sleep. Also, i find if rooted, that seting the min speed to 192 helps quite a bit.
Hi there. I have an iphone4s and I'm quite happy with it, except for the fact that I hate Apple. So I want to move back to Android. Things that I like about the iphone is the mail app and. mostly, battery life (battery consumption when screen is locked is superb, and that is the phone status usually). I'm not going to use the phone for games, but for calls, whatsapp, twitter, g+, music (lots of music playing), some video and gps navigation. I would like to ask people for recommendations on a good terminal based on (most important to less important):
1.- Battery life (I give importance to battery life when idle)
2.- Fast processor
3.- Fast charging
4.- Support for external storage (microSD)
5.- Cyanogenmod compatible
6.- If possible, the terminal sould allow me to replace the battery
Please do not comment on things like switch off wifi when not browsing the web, or switch to 2G when not using 3G to improve battery life. I do not do that now and I have power for 36 straight hours with my iphone. I'm not looking for workarounds for bad battery life. I'm trying to have the same battery performance I have on my iphone on a phone with Android without switching things on and off.
Thanks so much for your help

The pimp my Rom scripts for Android devices works also good for battery improvement.
But all you need is the Samsung s3 dude. Root it and script it with PMR.
Just lose the freaking Apple dude, you will be fine XD

Hello, welcome to droid! I'm surprised at your iPhone battery life. My friends 4S is always running out of juice.
Anyway, recommendations are hard as it also depends on your hand size and preference. I would say Samsung Galaxy S3 or Note II. They both allow battery removal and micro SD and have fast processors, I have an S3 and it charges fast. I currently use the SuperNexus ROM (cm10) and its excellent. For me the idle battery life is excellent, but much improved when rooted and using an app like Juice Defender Ultimate. This saves the faffing of turning WiFi on and off as it does it for you based on training with your nearby cell tower. The app saves juice from adjusting your CPU speed while idle too. There are quite a few features and once setup it does everything automatically, just pick your preferences first.
I use international version of the S3 btw. I'm going to say avoid HTC One X it has a smaller battery and no micro SD option.
Android is great for music playing. Not sure of the iPhones offering as far as equalizers but there are many choices on droid. I recommended the PowerAmp app.
Hope this helps you!
Funny, its excect the way around for me: hate Iphone, like Apple.
Thank you so much for your answers. I will probably go with the SGS3 or the Note II. My brother has a spare SGS2 that I'm going to test with cm10. I know battery is quite worse than SGS3, so if I'm happy with the SGS2 I will be definitely happy with either of the other.
Ignacio
If battery life is important for you, you might also look at an extended battery.
Seidio offers a 3500mAh unit for the S3 (stock is 2100mAh, so it's more than half-again as large). It does add a bit of bulk though and will prevent you from using any case except their cases.
Good luck in getting 36hrs out of any Android phone (with no power management regime) - it just isn't going to happen. Except for maybe a Razr Maxx or Note 2.
Just bought a s3 ,and im pretty happy with it ,just leave you time to understand your phone ...

Hello,
I am very much curious to know why android's battery management is so damn poor when compared to iOS. I have a Galaxy S4 and my friend has an iPhone 5. Agreed about the battery drain while on using it, leave that. But if I keep it idle without using it, still it drains , provided I have turned off location service, all account Sync and minimum display. Lets say while on 100%, if I keep my phone not using for 2 hours, still I could see battery percentage might gone to , let say 95%. On the other side, the iOS devices, while they are sleeping for 2 hours, it would be mostly 100% or 99%. I know one reason is samsung's additional service, but even the AOSP running Nexus 4 is not efficient as iPhones while its idle.
I was wondring if its possible , architecture wise, not via any software or rooted fix, but for Google itself, to change Andriod Power management efficient like iOS ?
I was wondering once, why apple is not going for big capacity battery. Their Power Management is so efficient that they are competing with others , let say the high end Galaxy S4 with 2600 MAh Battery with Just 1430 MAh Battery.

Since Droid requires many processes to be run in background eventhough if it is in sleep then the battery will be drained....

That is not problem of Android, an app is keeping your CPU busy, avoiding it to enter to deep sleep mode.
iOS better? Old analog iiiphone is even better, it has no battery!
Android gives you ability to control battery by yourself. Check what process wakes up your phone.
If default tool is not enough - you can download System monitor, or any other
I think because on iPhones the apps are frozen in the background when its not being used, whereas Android apps are still running on the background and not frozen. Freezing helps consume ram.
