The issue regarding charging the battery to keep the battery life as long as possible has always been debated for several years. There are many out there who either believe that it's now safe to charge however you want because of the modern technology and safety mechanism implemented on the phone. I still have this uneasiness though, particularly my battery health is about 85% after just one year of usage. I used to charge over night but I have dropped that habit about one or two months ago. Now that my phone is rooted, I wonder if there's a way to set the limit when we're charging the battery so in case I forget to plug it out or I want to leave it overnight but I still don't want it to charge to 100% I can do it.

Find app called " Battery limited charged" on Android and game app section at xda. It does good job.
i'm using this... propably the same as @tiennhu89?
it does need root but it works perfectly for me on poco eu miui 10.3.8

Interesting
I just use a budi charger - I set it to charge for an hour as I go to bed. I wake in the morning and my phone's at 80-90% when I wake
Bingo
Edit
This would do the trick
There this Magisk module called IPC "Input Power Control" that basically automatically switches charging off when battery level reaches a certain disable threshold and back on as soon as it drowns to enable threshold.
Look it up here in Github if you want to know more

To all people who helped me, thanks a lot. Now I don't have to worry about charging my phone to 100% anymore if I forget. It works like a charm. 10/10 would customize something else again.
No matter how far battery technology has come, it is STILL a bad practice to keep a phone plugged in over night. The constant trickle charging deteriorates battery faster. Also never fully charge a battery and also never let a battery fully drain.
I charge my phone to 80%
And never let it go below 20%
If you need my sources for proof, let me know.
There are two scientific studies done specifically on this.

One of the worst things you can do to a lithium battery is discharge it completely. They don't suffer from "memory" yet every time someone here in the forums complains that they are getting crappy battery life the instruction to discharge and recharge to 100% before clearing stats pops up.
For those who are interested here is an article that explains in detail.
batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
My main question- Is there some function in android that looks at the maximum depth of discharge level of the battery or is it that most people don't understand the characteristics of L-ion and confuse them with those of Ni-Mh or Ni-Cad?
I want to know because if I need to completely discharge to get better perfomance, despite the reduction in charge cycle lifetime, I will do it but only infrequently.
I've only let my battery discharge completely once, and it wasn't on purpose. From the posts I see here I think I get above average battery life. About 18 hours miui before I go for the charger and on 2.2 roms I'd get 20 hours and still have 40% or so to go. So no I don't think completely discharging your battery does anything for battery life.

I have never run mine down completely. Gotten it to about 6% but that was because I was fighting ROM flashing problems. I usually call 25-30% enough for me and plug in then. I am also getting 30 hours out of my 2.2 with a good deal of use. I used to have a Motorola and their batteries are total crap. If you EVER let it get down below 10%, it took some real work for it to charge correctly and boot up. Even as much as a hardware mod where I have had to cut the wires on a USB charge cord and charge it rigged up with the wires pressed against the battery and prongs in the phone. Very dangerous, but worked for a last resort.
Discharging the battery is not for the sake of the battery,but more so for the ROMs data and how it acquires the battstats usage. I only run it up and down and clear stats when flashing a new ROM, but I do use my phone moderate to heavy daily and have had great success in battery life the way I calibrate it.
The solution I think is to use a larger capacity battery and regulate it to narrower window of operation never fully charging or discharging.
The fastest killer though seems to be heat.
I have read several times that your phone does not fully discharge the battery...that there is still a minimal amount of charge,not enough for the phone to opperate but enough to not damage the battery when it shuts down
Maybe the batterystats file can be saved after being calibrated once and then restored after every wipe oor flash.. that would save some time aabd according to you guys, batt life too
Sent from a cell tower to the XDA server to you.
I've only ever calibrated my a few times and only after flashing a new rom. I never run my battery down after resetting the stats. I just use my phone as I normally do. My understanding of calibration is that it's not about squeezing more life out of the battery despite what most people think but of getting a more accurate measurement of the battery's actual charge. Also while it's true that the phone will shut of before the battery is completely discharged damaging the battery, allowing the battery charge to drop that low shortens your battery's life and decreases the amount of charge your battery can hold.
What gets me is I also read somewhere that for optimum battery life you should keep your battery level somewhere between 70%-40%. Of course that doesn't stop me from charging my phone to 100% everyday. I don't remember where I found that article but I'll post a link if I can find it again.
The reason this bad advice about completely discharging your battery persists is probably the same reason people keep recommending automatic task killers.

Discharging the Battery & Running the Battery Dead is 2 Different things!
We recommend running the battery dead ( Phone Shuts Off ) & recharging while off to train the Android OS from Full > Empty..
Running the Phone until Dead is not Going to hurt the Battery in anyways shape or form despite what you may think or read!
The Reason is, the battery is never fully Discharge & still holds Voltage.. The Calculations of Charged / Dead is at the Kernel Level, so even when dead it still has a 3.4v still or roughly..
As long as the kernel isn't tampered with, discharging the battery via the Phone will never hurt the battery period!
Now, Based on the link you posted you would have to run the battery down past the safe discharge point.. Via some other means of killing the battery, other than using the Phone.
To help ease your mind, Remember this:
~ Charge levels is controlled by the kernel
~ Even when Phone powers off, there is still plenty of charge in the Phone's Battery
~ Battery is never Fully charged, as this also hurts lithium batteries
Roughly every Android kernel does not let lithium battery get below 3.4v and at most 96% charged.
Hope this helps,
~Eugene
If you are still concerned wait until your phone turns off and stick your battery on a meter. You will see there is still power left in it...
My original battery that came with the phone got great life, then couple of months later it was discharging in like 2-4 hrs(froyo), so I called, they sent another one free...5-6 months later that one started doing it as well, so I pulled out the old one from the drawer, it powered on at like 85% ! and I was getting crazy ass life out of it on miui over 30 hrs one time...now that one is acting up again, so I'm going to try to swap again..lol...maybe there's something to not using them for a while...
I've used diff roms and combinations of draining/recharging...calibrating, not calibrating...it's always different results..honestly I don't think there's any rhyme or reason to it other than the fact that many vibrants have diff hardware and there will always be some weird quirk on a per user basis...
As far as hurting it by draining it all the way, I hardly think that's the case seeing as with both batteries I've always let it run down...not on purpose but there has been many many times I've plugged in at 1% or had to power back on because it died...charged it up and got 20-30hrs no prob..usually issues come up when flashing a new rom...
i think it all comes down to luck of the draw. ive had my vibrant since launch day, and i still manage great battery life. my battery is actually stamped 7-02-2010. every 2 weeks or so ill drain the battery completely, turn it back on and allow itself to die again, and finally allow it to fully charge overnight or 4 hours. i usually get a good 7-8 hours of constant use on cm7, or over 24hours if let on standby.
im still debating if i want to grab an epic 4g touch battery as well to increase it even more.

hi I've heard plenty of times that you should charge your phone once you get it or charge overnight..is this true in anyway? I always go straight to playing with my new phone and then charge once battery dies..any thoughts on this myth?
Hi. I have heard a few different things about this. I think there is a thread on here I read about it as well.
First is that it won't matter because batteries no longer need to have that memory thing.
Then there was one that said let it deplete, charge it and then when the light goes green unplug it and replug it in. The light will go red for a few more minutes and then green. That will set the battery.
Then I also read that you shouldn't charge it completely or let it completely deplete because that will lessen the charge over time
The last I heard is that (and this was under the discussion about extended batteries if I remember correctly) the batteries are made so that the battery meter tells us it is dead even though there is still a little bit of a charge on the battery that way it doesn't do anything bad to it.
So I really think it depends on who you listen to. I did the let it deplete and charge it thing once so far. I get decent battery life. I tested it and got 10 hours out of it with medium usage and I usually get more when I toggle off the 4g when not using it but haven't timed how long for that yet.
Hope that helps until someone who knows more specifics posts something.

I don't think it matters any more. I plugged mine in after I did initial setup and let it charge to green light, didn't do any special bump charging or charging while off. The battery is designed to be used as is, without any tricks. Always overcharging to 100% or completely draining to 0% is probably worse than just using it normally and plugging it in when you notice it's relatively low.
There's a battery log that Android keeps regarding voltage and reported capacity that it uses to adjust the percentage display that you see on your phone. This changes over time as it gets a better idea of how the battery discharges, so built into your phone is a mechanism to make sure the reported capacity is accurate. If it gets "off" a bit, like if you see a huge spike up or down in battery capacity after a reboot, it's just adjusting itself.
But, as you know, Android users love to control everything by themselves, and not leave anything to some process behind the scenes. Hence the clamor for root so we can install whatever we want. So some people like to trick this adjustment mechanism by force charging the phone to full when it's off, which gives the battery capacity adjustment mechanism a "true" full charge to base its reporting on. Also, I don't believe the kernels in stock ROMs will charge to what it believes a full 100% charge is, to protect the battery life. Bump charging kind of gets around that, if I understand the process correctly.
Also, I don't charge overnight (lack of outlets in bedroom) so I make sure it's topped off before I go to bed. Even if it's not, it can make it through the night just fine, since it's not being used. So that's not that much of an issue anyway.
TL; DR: Just use it, plug it in when you need to.
I really enjoyed the S2 guide(somewhere here in xda) about tweaking the phone so as to maximise potential battery time.
With the increased battery of the S3 I know its not as big of a deal but I'd still love to see a few tips on how to go about getting as much juice as possible from the battery on the S3?

I think the first few charge cycles to any battery determine how well they perform, I have put my S3 through 4 full charge cycles so far and the longest life I've had out of it is a smidge over 36 hours with fairly frequent usage, I'm looking in to optimisations for it but I think the charge cycles are key to good long term performance.
Would you mind explaining what a charge cycle is?
Sure..
Basically when I first got the phone I put the battery in and left it charging for ~16-18 hours before I even turned it on, next morning unplugged, turned it on, went through set up etc.. hammered it all day until battery died, went through the same process again (repeated x4 so far, on 5th full charge now)
It is important to charge fully then discharge fully a few times to allow the battery to exercise and calibrate its maximum potential.
After this partial charges are fine, but worth doing a charge/discharge/charge at least once a month to allow the calibration to remain good
Hope that helps,
R.

It's not necessary to charge up the phone before using it the first time I was told. If you drain it first time then proceed as you said afterwards its still basically the same thing imo.
Cool. Thanks for the responses. I'll definitely try one of these methods.

That is not true, a technician told me that newer batteries doest have to be drained and fully charged to perform optimal. It WAS neccesary back in the day with the older devices and no smartphones etc.
It is clearly marked on the directions to charge fully before use
I have this doubt since purchasing the Xperia Z!
As soon buy my Xperia Z2 and the store where I will buy it is difficult to leave the charging device 30 minutes before turning it on to test it!
As difficult as it was I let mine charge for an hour or so before I used it. Not sure if I needed to but was in work at the time so had a few things to keep me busy while charging

My phone had 62% battery when I recieved it. Probably my contractor that installed some apps and charged it. I didn't charge it untill it was empty.
I wonder what is the need to leave charging for 30 minutes before turning on the device for the first time since the other brands of devices do not need it!

Mine also came with 60% battery when I got it, I think its normal to keep a charge in the battery because it helps battery life.
I let mine drain right down that first day then I charged to 100% overnight.
I currently get to end of day with around 50-60% left
You should always charge them to full before first use. The charge that's in there is only a manufacturing charge, which is enough to keep the cells active.
Also, you shouldn't drain it completely. Lithium works best from around 30%-80% charge.

What I find strange is why other brands of devices do not have this rule??
Li-ion batteries don't need to be fully charged before first use. They don't suffer from "memory" like Ni-Cd. But it is true that for best life you should charge it between 20/30%- 80%. If you plan on storing the phone without use for a long time, best is to charge it to 50-60% (not 100%) and put it away.
Go use and enjoy your phones!
PS: A few laptop manufacturers (like Samsung) have an "extended battery life" mode that you can enable where the battery stops charging at 80%.

You're right, they don't have the memory effect, but they do need charging before use. But yea, storing with at least 2/3rd charge is best.
BTW I sell batteries for a living, have done for 15 years.
Ok so is the correct answer yes, charge for 30mins or not necessary? Seems both sides of argument has support

As an electrical engineer I have to say: You should charge it before first use. 30 mins charge should be fine.
Well, it might be not so obvious for the battery in Z2, as it was manufactured not a long time ago, but it could end up in battery degradation, if the battery has been stored for a long period of time without usage.
Ok so with the Z2's being manufactured within the last month it probably isn't needed then

Well, it's hard to say. Precharging the phone won't hurt.
I charged my first z2 for half an hour, and my second one was up and getting flashed within ten mins. I actually found the second one to be better on battery. I do agree that if the phone has been sat dormant for a long while you should charge, but as these things have literally just been made it'll make zero difference.

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.
