Okay so every time you flash a ROM, people say you should calibrate your battery, that is fully charged it, let it drain, then recharge back to full to optimize battery life.
My question is, why the heck would that affect the actual battery consumption? Sure it makes sense that if it's not calibrated, it may incorrectly report the wrong % of battery left but how does that change how long the battery lasts. It would make sense that after a calibration, the phone would more accurately report the percentage of battery left but I don't understand how it changes the rate it at which battery juice is being consumed.
No one knows?
just a guess: could there be build in shut-offs when the % reaches a certain level? So if the % says 0, the phone shuts off even if there is more juice there?
Calibrating the battery doesn't affect battery life, period. Calibrating the battery can however affect the accuracy of any kind of battery percent monitoring apps you may have.

That's what I thought too! It's just that, there's always so many people complaining about bad battery life and then other people telling them to calibrate the battery and they come back saying "oh yayyy, my battery lasts forever now!"
Doesn't make any sense
Just draining it and fully recharging it is NOT calibrating the battery. That is not the procedure to do a calibration.
It *can* lead to better life by recalibrating the full point and empty points. If the ROM isnt reading the battery life properly then it can look like you have much less battery than you do, or that it is draining much faster than it is.
By my understanding, because of the way modern phones are set up to display battery life, sometimes the meter will read differently from the actual battery life. Your meter might read 100%, but you really might only have 85% or 90% charge. Calibrating helps to bring these measurements back into parity, increasing the perceived battery life of your device by allowing you to use a full, accurately read charge.
One thing I do know, the bit about letting your battery run to empty and then recharging is outdated information. The batteries we use nowadays don't benefit from that kind of behavior.
Calibration is for the phone not the battery, the phone needs to adjust itself to the battery %, seems to fix itself for me over time, through reboots, etc seems to get really good battery life, placebo effect is in motion....

I will edit the post as other suggestions come in.
This is what I am doing and it works very well for me. Keeping all things equal... meaning keeping your screen brightness the same, keeping you live wallpaper if you have it you should see major improvement in battery life.
Draining a new battery to 0 and charging to 100 percent several times will help extend the battery life.
Anker 1930mah I find add 20 percent better life.
I have stock HTC 1 by 1 widgets on my home screen that allow me to easily manage wifi, mobile data, sync and airplane mode. I suggest turning off backround data and auto sync.
New Energy ROM and stock videotron kernel is the best battery life by far and it a awesome Rom.
OC_daemon comes with energy rom.. i use it to drastically reduce your cpu speeds when screen is off and even can reduce when the screen is on if you do not run a lot of widgets / high demand apps...
Let me know how it works for you...

for the last time, lithium ions have been out for over a decade now...they do not have memory so there is no need to cycle these batteries...draining the battery and overcharging it is actually bad for lithium ions...lithium ion batteries must be in a constant state of charge and discharge to extend battery life...draining to 0 and 100 only recalibrates the accuracy of how much battery that your phone shows that is actually left in your battery. also draining the battery and overcharging lithium ions is a very bad idea and will significantly decrease the life of the battery...
the other points are absolutely true and valid and recommended

I never suggest overcharging your battery and battery memory is not the reason for a full charge and discharge.
Fully charging battery helps the phone properly read your battery and use the battery output evenly. The batteries drains at a more constant rate.. I would say it settled down.
According to Anker... to reach the best performance, full charge and discharge your new battery for 4 to 5 times.
I know you do not agree but that is my experience and that is what the maker of the battery suggest. So this should be done.

I know what you're talking about. It's an old mentality that refuses to Die form years of using Ni-Cd batteries. I have a post about this somewhere I just can't find it. search up battery university lithium ion on google. It'll tell you lots more. If this was true all companies with lithium ions would tell you to charge and discharge multiple times...but newer companies like samsung and sony don't even recommend this and they just ell you to charge until full, on many of their products with lith ion now.
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
Li-ion does not need to be fully charged, as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge, because high voltages stresses the battery. Choosing a lower voltage threshold, or eliminating the saturation charge altogether, prolongs battery life but this reduces the runtime. Since the consumer market promotes maximum runtime, these chargers go for maximum capacity rather than extended service life.
there are more articles in other places just got lazy lol

Those test mean very little because in the real world those batteries have to work our phones and not a artificial charge / discharge cycle... Meaning fully charging and discharging you battery allows your phone to properly read your battery and use the battery output evenly.
I would also point out that in that article does not say that a full charge and discharge of only 4 or 5 times will reduce service life. Yes doing this habitually will...

correct...the only thing that cycling a lithium ion does it to read the battery life properly...it will not affect battery life at all, unlike older ni-cd. its a race between getting a longer battery life or a longer runtime...if you want you battery to last...then i suggest you don't charge to 100 percent and you don't let you phone die...if you want more runtime which is what everyone wants, then you have to charge to 100...but as many people notice...going from 80 to 100 takes a long time while going from lets say 20 to 80 takes the same amount of time...also battery drains very quickly from 100 to around 80 percent..
my only point was that you do not need to cycle your battery multiple times. Once time should be enough for you phone to get a good handle on your calibration...besides you can always recalibrate the readout using an app.
If I have lots of widgets, can that suck more battery, also, my network is off all day, turn it on whenever I need it, and sync is off too.

I have seen lots of threads about people complaining about very poor battery life after flashing roms. Sometimes battery charges to 100% quickly and discharges very quickly.
So, these are the solutions. These solutions are IN ORDER. If the first one has no effect, then try the next one. If the second one doesn't work, then try the third one.
Now-
1) Try reflashing your ROM.
2) If reflashing your current ROM doesn't work, that probably means the ROM itself has poor battery life and you should change it. Stock ROM's have the best battery life.
3) If you are on stock ROM and still having problems, switch off your phone, take off the back cover and remove the battery. If the battery is swollen or the shaped weirdly, this means your battery is dead and almost useless. You need to buy a new one.
I recommend buying only stock batteries manufactured by Samsung because other batteries can be fake, incompatible, or just used batteries sold to you. Don't buy anything else unless you're absolutely sure of what you're doing.
Hopefully I helped.

General tips for saving your battery-
1) Switch off mobile data whenever you're not using the internet.
2) Change your wifi sleep policy. This can be done by going to wifi settings, pressing menu button and then select advanced.
You can change your sleep policy so that your wifi sleeps when the screen is off.
3) Decrease your brightness! Your screen is responsible for most of the battery drain. Increase your brightness only when you are in bright sunlight or when you're watching videos etc.
4) Switch off GPS. Keeping it on all the time also drains a lot of battery.
5) There is an app called 'Greenify' which hibernates the apps running in the background. This app has increased my battery life. Here a link https://play.google.com/store/apps/...e=google&utm_medium=organic&utm_term=greenify
6) Don't charge your phone when it's at 70%. Wait till it is between 20-30% and then charge it continuously till it reaches 100%.
7) Let your battery completely discharge once every month.
8) Don't use task killers. They use more battery life than they save.
9) NEVER charge your phone overnight. Your phone takes only about 4 hours to charge. Overcharging reduces your battery life
10) If you use a Bluetooth headset, switch off Bluetooth whenever not in use.
11) Using setCPU profiles. This is one of the most effective ways of saving battery. You all know about overclocking, but do you know about underclocking or undervolting? Using profiles, You decrease the clock speed of your CPU when certain conditions are met. These profiles can be on the basis of time, screen off/on, battery etc. So when my screen is off, it automatically reduces the clockspeed which saves battery

Using these tips, I have gotten almost 2 days of battery life on stock Roms and a whole day of battery life on custom roms like CM10.1 and CM7
If you have your own battery saving tips, please share and help expand this list.

Are you sure about these? Because I've read that phones only take how much ever charge that they need, so charging overnight isn't a problem. And i've also heard that letting the battery charge fall below 40% actually reduces the life over time.

Yes, I am sure and it is something I have verified.
Overcharging kills the battery.
I saw a video once of an evo 3d. The battery almost completely died after it was charged for 3 days
And you should always charge only when your battery is low.
This will ensure longer battery life

Normally, when the battery is fully charged, the chip that controls the charging process reduce the current exponentially to 0: this avoid the overcharging.
I think all smartphones have the charging chip control integrated (an USB cable is simply a power source, not a battery charger), so I hope we can leave the phones on charge all the night without any problem. I do that always and never had problems.

Quoting Dianne Hacborn(Android Framework Engineer):
"Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away."
Its just a myth mate..
And also, it's a myth that you should let ur phone charge reach 10% or get fully discharged before charging. This actually leads to decrease in the battery life over time.

Think of your battery as a person working out and charging is like taking rest. If the person's ability is to do 100 reps yet he takes rest after only 60 reps and keeps doing that continuously, he won't be able to do 100 reps after a few weeks!

This! Anything about wiping battery stats is not a myth anymore, so please stop misleading people,
Also "6) Don't charge your phone when it's at 40%. Wait till is below 10% and then charge it continuously till it reaches 100%."
Not true! Charging your battery around 50% is the most efficient way to keep lithium battery alive longer. A discharge once a month is also recommended.
This is app is a must have and thought I'd share. Like everywhere I have read, they say battery should not be charged to 100%, it will hurt the battery somehow. This app "Battery Charge Limit" automatically (with root) stops charging the phone at whatever percent you want and starts charging back up at whatever percent you want. So you can always stop before it hits 100. It can be used without root but it only notifies you and you have to manually unplug the phone to stop charging. Better with root since its automatic.

Keep it turned off for a better batter longevity ??
Damn thos people are more preocupied of how to prevent the battery wear than actually enjoying this amazing phone
Well coming from an HTC device where after like what 6 months, my battery starts dying much quicker and hopefully this app and the nature of Samsung makes my phone battery last longer. Never owned a Samsung, so I don't know how the battery lasts over time.
This is a myth, modern phones already prevent damage from overcharging with the charge controller in the phone. Fast charging and slow charging also does not make a difference in battery longevity.
Just use your phone like a phone.
Yeah no
@nukeclears you need to bone up a bit more on battery chemistry before making statements like this. Overcharging is very different from charging to 80%. That's why Apple just implemented a charge limit in ios13 and Tesla strongly recommend charging to 80/90% max for daily use. Samsung just don't want to do this because they haven't felt enough pressure. I'll bet they implement it on the S11 and then for all phones by the end of the year.
Tab S4 has a setting to stop charging at 80%
You guys do need to go through all this? For what?
I have a Note 3 with battery since 2014 or 15, it still gives me the same power, sometimes it's better than it first was.
Charging fast/slow doesn't affect anything, I'm doing so for years.
I really don't think batteries die, if you felt it's weakening, just change OS, not the battery.
Samsung themselves, on the s10 series, suggest to charge from 30% to 80% everytime you need a charge.
In my daily usage, stopping charge to 90% is enough and I have all the juice i need till the next day.
If you are rooted, Battery Charge Limit app can be very useful to optimize the life of your battery (remember: battery is the first hardware component that ages your phone). On my 2015's Sony phone, they wanted me to pay 75 euros for battery replacement...
This thread is full of people who know nothing of batteries.
I bet your phone battery does "feel" the same after years when your os pushed that update that permanently limited your frequencys lmao.

Enjoy replacing it every year because phone batteries are becoming more commonly HARD GLUED into place. So go ahead, switch the whole phone out.
The previous generation believed that keeping the phone between 40-80% was the best way to ensure that your phone battery continues to perform at its optimum levels for months (and years) to come.
With all the optimisations for battery life on our new phones, does this advice still apply in 2019?
I would love to squeeze every drop of battery juice from my phone before having to charge it, and I'd also love to charge the phone all the way to the max 100% (never overnight though) but if these habits could compromise the health of the battery then I'll stick with the 40-80% range.
What are your thoughts?
Yep, still applies in 2019. Make good use as well of the battery care and set it to your sleep schedule so that it'll stay at 90% and fully charge by the end of the schedule you set.
Sony has been bundling a smart charge functionality in the phone to keep it charging up to 100% when you will need it so I stick to that. Having owned 3 Xperia phones so far i had no issues with battery life nor battery quality. I believe its a bad idea to let the battery drain or keep charging it at a specific % as it creates what most people call battery memory

This. Sony ALWAYS nails the battery stuff, and this device is no different. Once it figures out your resting pattern, it'll manage everything for you.
