Hi,
I feel that my battery is going bad after about 8 months of usage. I'm not sure if i still have the warranty (it was bought in different country).
I changed to fully stock rom but it's the same.
It get's fully drained in about 8-10h. Light usage. Even with all the stamina mode/low brightness etc...
The worst thing is that when it's down to about 30% or less, it starts acting up. The % would drop to 0% and the phone would turn off, then after i would turn on the phone again, i would see 70%, then 22%, then 30% again, something like that. After that it might "hold" and work for a few more hours or it might just keep on turning itself OFF.
What the hell is wrong with it...?
How do i replace the battery on this non battery replaceable phone?

You open it up search for Xperia P service manual.
Maybe it's not the battery just the stats? How long do you charge it?
hi, thanks for your answer
i charge the phone overnight and in the evenings
from 7am, until 16:00 it is almost empty with virtually no usage since i'm at work...
sometimes i need to charge it couple of times a day if i use it frequently
battery stats have been deleted, new rom and all...don't know what more to do

No software installed?
Post bat stats along with CPU Spu Plus free(check enable charger events at settings) and Wakelock Detector (check the statistics since unplug in settings) screenshots and we'll see if it's the battery or something else.

thanks, i'll give it a shot and when i'll have all info i'll post it here
For Less battery, go for Custom ROMs
I don't find this kind of drain now.. I felt it in my previous ICS. Now am in Enigma 6.1. This ROM has some mod, which will makes the phone enter in to deep sleep mode after 5 minutes. This makes it more battery friendly....
MoonBreaker v3.5 also a good choice.
sorry guys, i forgot to post my results, i will try to get that info by tomorrow
Anyway, i found this on ebay and i'm thinking on giving it a try. Do you recommend i buy somewhere else? Is there a more quality product out there?
I also found a dissasembly video on youtube how to get to the battery and it doesn't seem that hard + the battery on ebay comes with all the needed screws which is nice.
I have tried 5+ roms and none of them changed anything.
But something troubles me...i spoke with a guy from the Sony repair shop and he says that it's not necessarily the battery, it might also be a problem with the motherboard.
I do not have the warranty anymore so motherboard would be the worst option. Phone works normally though...
I hope some results from the mentioned apps might shed some light on this.
HI
Why dont you try DU Battery App , it will help you to charge it fully. What i observed is that even though the battery status will show as 100 % but when you check Setting --> About phone --> Status --> Battery status it will still be showing charging & if i keep it plugged in for another hour or so it turns to battery status --> Full. So using this App DU Battery you will be able to actually fully charge the battery . Also if you try a custom rom with custom kernel like nemesis 6.3 you will be able to change the cpu govorner settings and can save more battery.
thanks, i'll check it out
i have locked BL so no possibility for custom kernel

Hello everyone,
From yesterday i started facing a strange issue due to which i am experiencing serious battery draining issues.
My battery started draining 1-2% every 5 min in idle mode after i played a game named crazy fist . next day i factory resetted my phone. In idle now it is not consuming any power but when i do some work on my phone , it consumes alot of battery and it.drins like 1% every 2-2.5 min.
Charging time is normal. But discharge is pretty fast.
So i checked thr battery usage inside settings.and noticed that my display is consuming about 41% of the battery and android os arnd 13%. I am not sure qbout os usage but thr diaplay is consuming too much power. I think initially it used to consume 13-20(max)%.
Or is the usage correct? I am using sgs2 stock midel and have no intentions to root it.
Kindly assist and reply asap. Thanks in.advance,
Siddhanth
the display on the galaxy s2 does drain alot of battery if your using it for quite a while..thats what they call screen on time..my battery was draining fast and i panicked... when you do use your phone how long do you use it? say do you use to browse like for a good hour non stop?
if you was rooted i could of gave you some options but here is a link to help you read and give you some tips on battery life...
http://forum.xda-developers.com/showthread.php?t=1234264
charge your phone fully and drain it without switching it off..charge it again without taking it off charger i say leave it for a good few hours...do the same thing for a few charging cycles and see what the battery like is after that..but check the link
But this strange thing happened to me aftrr 1month.
I wss never rooted.
I mean this is the first time my display is consuming 59-61% of the overall battery. is this normal and does it hsppen to u too?

i thought the same as you buddy. never realised it in the start when i had my s2 but then checking the battery usage and i panicked...its normal for the display to drain the battery alot..
change your brightness to auto and there is an option in settings and display where you can tick to have the display autoadjusted. thats for brightness..
or do what i do and have your brightness on the lowest settings and see how it goes from there...fully charge your battery let it say for 6 hours then let it drain till it dies down without any breaks and then charge it again to the max..do the same thing for a few times and check whats the battery after a few days...

when calibrated your phone you leave it on of course and charge it without any interuptions...when you let it drain with out any breaks like switching it on and off, once it dies down then plug to charge it.....it will charge and it will give you the battery icon...once its fully charged you can see by the battery when its fully green switch your phone and your good to go...

hey buddy sorry for the late reply..go to market and download the battery calibration app by Nema..once you installed it charge your phone fully go into the app and just follow the instructions and then you should be fully calibrated..
but download the app first
Thanks, i tried it todsy but it says root needed.
I have a stock rom. and i dont want to change the rom before my warranty period gets over.
Install BetterBatteryStats from the Android Marketplace. Run it and see if there is/are any app(s) gone rogue abusing CPU power other than the display.

Hi XDA
I have some questions regarding the gs3 battery.
1) Does overnight charging the battery harm the battery?
2) To which percentage should the battery percentage drop before charging it?
3) How can it be that my phone is awake often, dropping the battery more than normal, while I always close all apps and innternet?
Thanks in advance and good sources for the answers are welcome.

1. I have never had an issue charging overnight infact this is the only time I charge my phone. I may get corrected hear but I think once the battery is full the charging stops.
2. You can charge your battery at any percentage a common misconception is that this harms batteries, that was true in the old days with but with the newer batteries these days I dont think it is. Also You should not let your battery run right down everytime and your device switch off before charging. I normally do this once a month but everyone has a different opinion with batteries. I am not saying I am right and they are wrong because I no expert these comments are purely my own opinion.
3. Even with apps closed there could be an app still causing a wakelock if you install BBS (BatterBatteryStats) you should be able to see what is causing your battery drain.

1. Depends on your definition of "harm" - ANY form of charging will "eat" a little out of the "battery health" (for phones, notebokks and anything else) - however I believe that a well-planned charging strategy would be a great thing for a phone! And one at night seems to be perfect
The major trick IMHO is to avoid recharging with high currents - I believe the stand-alone recharger is pushing about 1000 mA while you will get like 475 mA from the USB port of a computer - that last one will generate a slower but MUCH HEALTHIER recharge (and will also avoid overheating). In order to control that you can run a custom ROM in the phone (in such a ROM for instance with the Siyah kernel it is possible to set those values above - and many other - with a program called STweaks). Of course that a smaller recharging current will mean a longer time to 100% but overnight that should not be a problem.
So the bottom line is that you should recharge as needed, and if possible plan for overnight recharging with the smallest current and at the longest possible interval (I try to do it every 2nd or 3rd night - but that is rarely possible - I need to get one of those 4200-4500 mHz batteries ).
2. Lithium can be generally recharged from any percentage - HOWEVER it is recommended to avoid always recharging from the same (high) percentage - that is a well-known problem with notebook batteries that are kept always plugged-in and are going 100% -> 95% -> 100% -> 95% -> 100% forever - that generates an aging much larger than expected, and some companies like Lenovo have a special mode of battery recharging strategy specifically to avoid that.
That being said I doubt that you keep your phone in the charger at all times, so that should be less of a problem. However I would avoid recharging too often from above 80-90%.
3. I understand you have found your "bad app"
A bit of a spaniard in the works here .
Just a warning we have had a number of posts >>> phone on charge all night dead phone in the morning .
Why i dont know but all have been motherboard jobs .
In theory it should turn off at full charge .

Hello! I bought this phone last month. Since I got it, I've never experienced any problem with it. For four days, I noticed that the battery drains very quickly, without any logical explanation for this. The data connection is turned off, Wi-Fi is turned off. Last evening, I charge it to 100%. This morning,I found it turned off, with 0% battery. What solutions do you have to solve this problem? Have you encountered this problem?

Can you please provide some more details on this?
I.E. What is it plugged into to charge? Laptop, Desktop, AC, etc etc.
- I ask this because I had a phone that would actually consume more power than a USB port could put out. when turning off the laptop, it actually allowed a back drain for some reason, and the next morning the device was dead. (Not this phone)
Also, what applications are running? Any?
Finally, you can try to retrain your battery... Wiping stats does not work, ever. So despite what anyone tells you, don't do it. You're just wasting time. SOURCE
So, how do you retrain your battery? Let it die completely. Then plug it in to charge. Don't use it while it's charging if you can help it. DO NOT remove it from the charger until it's at 100%. Once this is done, use it til it dies on it's own. Then yet again, charge it fully and then go back to your normal use.
In some cases, these batteries can go bad, for various reasons. A quick test, but is not always trustworthy is to spin your battery on either side. If it makes more than 2 full rotations, it's swelling and going out. Replace it.
The best alternative is to take it to a battery shop, and let them put it on a Cadex machine. (Pronounced Kay-Dex) ... This machine will charge and discharge the battery several times over a few hours and truly test the current life -vs- the life it should be. Anything rated less than 80% remaining life should be replaced.
SOURCE: I work here
I charge it only from power outlet, with stock charger.
Trib wrote 5 paragraphs on info you need to provide and you come back with a small sentence? Pretty much if you use your phone a good amount it will only last you a day per charge. Unless you give us an explanation on how fast it is draining it's impossible to even start helping

6 hours 40 minutes from 100% to 10%, and the phone in stand by! Cell standby - 45%, Phone idle - 48%, Screen - 7%
And all this after a hard reset and retrain battery! The battery is almost new (aprox 1 month)!
I want it to make a screen shot of battery drain, but I have no clue how to do that on LG L9...

I attached a screenshot. Yesterday I changed the battery. Same problem! I take it this screenshot this morning, after I fully charged the phone ... Same problem, a new battery.
Can you please tell us what applications you have running in the background?
Also deactivate google now.(or the google services in google maps). download and install GSam Battery Monitor and after a cycle tell us what applications are eating your battery the most. It's clear that you either use yout phone(screen on time) allot or there is/are some applications that prevent your phone from going to sleep.
I use battery widget reborn and it shows me wneh the phone woke up,when the phone had the screen on,wi-fi on,gps on. Try it as well.
I also had battery issues when on JB. I downgraded back to ics. It's much more reliable when it comes to battery life. And the performance is about the same.
I don't have any app installed. After i replace the battery, i made a hard reset and I did not installed any app. I will install cpuspy and betterbatterystats for more results. I will back tomorrow. Until than, maybe you can provide me more advices. It can be from a damage sim card?

It's not that. Not the signal. It's the firmware. JB has these problems. In ICS Display is the major consumer followed by Phone Idle and Cell Standby.
I also had these problems in JB and reverted back to ICS .
I would advise you to install CM 10.1 on the phone. The battery life is better than stock. I get around 12-16 hours normally. The latest RC4 has fixed almost all the bugs present in older CM 10.1 variations. Give it a try.
I will root the phone and I will give a try with CM 10.1 or I revert to 4.0.4. If all this will be for nothing, I will sell the phone!

On ICS you will get great battery life Telling from my experience as i have reverted back to ICS after trying JB and CM 10.1( both have very poor battery life ) . So instead of wasting time just flash ICS and forget about battery issue :good:
Where can I find a tutorial to revert to ICS?
Same question. Can some one please give a step by step guide on how to revert to ics for l9

Use the offline flash..
I also reverted to ICS and the battery drain keeps like a countdown
I have the p769, and I offline flashed up to V20D (and rooted). Removed some tmobile bloat, and I have pretty decent battery life. I guess I'm lucky.

This is a topic I started on Xperia Support Forums: http :// talk . sonymobile . com/t5/Xperia-X10-mini-pro/Performance-Issues-of-Battery-BST-38-on-Xperia-X10-mini-pro-U20i/m-p/402537
My Battery BST-38 is discharged so fast that I cannot even tap OK button on "Battery Power Status 15%, 10%, 5%" messages.
I have managed to open Service → Service tests menu and applied Battery Test. After some hours spent on battery test:
Result
REDUCED CAPACITY
I have stock software and hardware. Only some apps installed from Android Market. Nothing flashed, nothing rooted, nothing hacked. Maybe some cracked apps (for trial, for sure :angel: )
Nothing modified.
And my battery died after 10 months. All I have been doing to my U20i is daily recharging for sure.
So, the question is:
How can I get my batterie's health, fitness, performance back?
Or you can recommend other things, you are the pro.
(PS: I'm living in Türkiye.)
Peace and love.
Just remember- never discharge device completly
Charge it with the wall-charger only, NOT through usb.
Make it charge for about 3.5 hours every time, even when it says it's full.
Recharge it when it's somewhere between 15 and 20 percent left.
If you don't see improvements this way, you may need a new battery.
I should say thanks to you.
Now I just need one more question to be answered:
When I am going to buy new battery, how should I prefer it to get best strength / stamina / durability / performance? What kind of battery should I choose in manufacturer , #value of mAh, #value of Wh, etc. categories?
Note: Stock U20i battery says

Sorry I couldn't understand what exactly you meant, so I'm giving lots of answers:
Test results are being saved as */LOG files on SDCard with date informations without any need to overwrite.
On the phone, no hardware (including battery and inner-case) or software is modified after factory.
I have tested ex and newer batteries and ex one took 1,5 - 2 hours to test but new one took more than 3,5 hours. Then I got the same "Reduced Capacity" results for the tests on each battery.

You can wipe the battery history using for example: THIS app.
It will completely erase everything android thinks it knows about your battery, resulting in it treating your battery like new. It may change the opinion android has of your battery and thus give you a more reliable estimate, instead of working with, (what may be), old or invalid data.

Thank you for the trick, sir. I will try it.
I would like to inform you about new battery:
Altough new battery failed at the test (Battery Test in Service menu), it does just fine without anything abnormal.
I fully recharged it 18 hours ago, and since that I'm using my U20i as a casual user, my battery's status is 48% now. (in 18 hours: with mobile data traffic on, texting for ~1 hour, calling for 20 minutes, web browsing for 30 minutes, background services off and brightness full.) I think that performance is just good but I have no idea battery failed at test (as you mentioned, maybe test results needs to be wiped) OR just maybe it has less mAh (930mAh) than stock one (970mAh).
So I will find out what causes this.
Now I have one new question: How should I use my battery? I will charge it when it reaches 20%~15%, while recharging I will try to use not it as possible as I can. Any more tips or tricks?

Now I have one new question: How should I use my battery? I will charge it when it reaches 20%~15%, while recharging I will try to use not it as possible as I can. Any more tips or tricks?

48% left after 18 hours with the usage you specified is not bad at all.
You can use it when it's charging, that's not a problem, but try to charge it through the wall-charger as much as possible, and not through usb.

Some people told me it's bad to discharge battery while recharging it, and I found it legit. But recharging is not a problem for me, because I will recharge it when it's night.
Can you or anyone recommend me anything more about battery health? Any advice will be appreciated.

The wall-charger will deliver more juice than the phone needs when you use it, so it's not really discharging, just charging slower. That said, if you don't need to it's better to just let it charge.
As far as battery health is concerned, just don't let it go below 10%, emptying it completely is not good for this type of battery. There's not much else to it.

Thank you a lot, sir. I will always remember your advices. :good:
Oh - I almost forgot to ask - What should I do about overcharging? I mean, what to worry about?
Device: Samsung Galaxy S2 (GT-I9100) T-mobile carrier- unlocked, Rooted ,Running stock rom with a Philz touch recovery
Problem occurred after about a week of purchasing a new battery since the old one got swelled... but i have two brand new batteries now both are not original but good quality (1 Year Warranty) With both batteries I had the Problem
Let me explain the problem :
______________________
Device would go off in at a certain battery level from 30%-50% (as for my experience):fingers-crossed:
To turn the device ON plugging in is compulsory... but then the battery would be Completely drained..
Also if you try to do a restart at a battery level which is closer to the sudden death the after re boot the battery will be at a extremely low level and wont rise...
I searched all of i can to find a cure to this because the last thing u expect in a situation is your phone dying?
Apparently the problem seems to be that the phone is reading the battery wrong? about a 40% so simple do a calibration Nope Nothing not even a change...
Here is what I tried
_________________
Calibration Methods - Apps and manualy
Reset the device
Let the battery chip reset
and all other methods
but finally i decided to reflash another stock rom :silly:
and I Downloaded This file I9100XWLSD_I9100XENLS1_XEN Since it was a Genuine Netherlands version but i decided not to go with T mobile this time:fingers-crossed:
I Wiped all the phone in Recovery then went to download mode and using Odin V1.85 I flashed the stock rom:fingers-crossed:
Turned it on using a Fully charged battery that i charged separately and i used it for some time max brightness max vol radio and gps wifi bluetooth etc. to drain the battery and at 38% phone started to flicker and turned off again:crying: (no Sim or Memory inserted no apps downloaded)
But i decided to go again i plugged it in ( never changed the batt) and let it charge for about 95% and turned all on again and this time i put on my simcard and memory and did all what i did except that i downloaded whats app and instagram. and also when it reached below 55% i Played some music and locked the phone (NO SCREEN LOCK USED) and after some time i checked batt was at 38% :fingers-crossed: immediately i locked it back and left it again....
Viola !!!!!!!:laugh: last time i checked it was 15% low batt warning came ( haven't seen it in weeks) and then the battery drop was a bit fast and at 12% the screen got a little flicker so i plugged it in.. I think the problem is halfway solved, ill let the battery go some cycles and update soon.. also i will attach some screen shots off the battery level too and take a close look at the time and battery level after 15% on the pics
:victory:
Here is the original thread i created

So yesterday I plugged the device until it reached about 85% and unplugged it when I was going to sleep, and at about 8 o'clock this morning i noticed that the battery level has risen to 96% , I think that is because the phone slowly gets to know the battery level correctly.. and right now it 11.08 am and I had turned on Mobile Hotspot and Data from 8 am , battery level is 82%.
I'll update again tonight when the battery drains completely

Can you also share the SoT ? I know it depends on how a person uses the phone but still I want to have an idea. I might also try this to have a better battery life. I also once tried that exact stock rom but without even charging completely, I went on to another ROM. So I am gonna give it another try today . :good:

Hello Eren ! Whats SoT? and you also have the same problem?
So... Now the problem is still there.....
Phone went off at 43% and also figured that there has been a near vertical drop of battery from 40 % to 12% and thats when the device was standby,
phone goes off only when im using it?
Can a Expert please look into this matter and help me please. looks like all what I did has been useless

SoT=Screen on time. And no I don't have this problem. But I want to try the stock rom so I wanted to see what your screen on time is.

btw its charging now so ill give you a number when the battery drains completely
I have the same problem. when I reboot my device in most of cases the battry level showed is a 10/30% lower than before and also my phone shuts off showing 10% percent or less and the sreen brightness goes a bit crazy for 2 secs before it shuts off. I have the original Samsung battery but I also bought the 2000mAh extended kit but now this issue happens in both of them I've read that I have to callibrate battery so I will try this and post results
1. Turn off your phone.
2. Fully Charge.
3. When getting 100% signal, unplug quickly.
4. Pull off the battery and put it anywhere.
5. Wait for 180 seconds exactly (be careful )
6. Meanwhile, take this opportunity to dust off the internal compartment.
7. Put back the battery on the right side.
8. Turn on the phone.
9. Pray the Battery god
10. ... and voilà !

I did it and my results were this. My phone shuts off at 5%, slightly less than other times. I rebooted it once while 80% percent and remained the same. Battery lasted 2h and 40 mins with medium/high usage
I would say it fixed something for me but not a lot. Now im going to try it with the 2000mAh samsung battery
Edit1: now after another full cycle the battery lasted for more or less 3 hours with medium usage and shutted off at 8% now im going to try on my 2000mAh battery that had an 8% and it shutted of normally with the shutting off screen and without weird screen brightness tweaks

Well I think it worked for you because you had a Original Samsung Battery Right?
In SL a Original batt would only come with the phone :crying: Fakes have invaded,,
So i read some where that fakes dont have the original capacity? so if it is then it would match perfectly !
so now im in hunt of a original hopefully this is not a phone problem
No its not definetly a phone problem and it isn't a big deal to find an original samsung battery for sgs2 however the Samsung 2000 mAh battery kit its waay harder to find and the ones that I found are more expensive than when it came out
Yeah, I definitely think the problem is with your battery, so you just need to replace it.
Btw guys, what is your general Screen on Time with your standard 1650mah battery (not extended)? I'm running CM13 and I barely get 2h on a single charge, but then I read reviews from the early days of S2 and for instance here they have 4h24 browsing time (with screen at 50% brightness) or 8h video playback.
Is it all related to being a different ROM, or my battery just needs a retirement? Being a different ROM would impact so much on the Screen on Time? Also, I have auto-brightness always enabled, would that have such a significant impact?
Greetings
EDIT: Since I generally use the phone indoors I don't think that would be the difference in such a different Screen on Time

With 1650 mAh and on CM13 nightlies, my best so far is 2h and 28 mins with brightness at between %0 and %25 and only wifi is on.
That 4 hour SoT is probably on gingerbread though.

Being gingerbread would make so much of a difference? It's like twice as much SoT...
Thanks anyways

Never used SGS2 on gingerbread but it is possible I think. I remember reading on forums that people started to get worse battery life with ICS and with JB it got even worse. So yeah probably possible.

Hi Bolshoi! I will definetly update the SOT on the stock rom after the new battery arrives! I asked one of my friends who is in Netherlands to buy and send me a batt. Regards!

Im From Sri Lanka Achimakulo its so rare to find a Genuine Samsung battery for a older device like mine and even if i found one its either old or way too much priced
I think its because my device is so rare in this country
Is it fixed now??
See attachment
battery level drop is natural? ?
