My galaxy s2 has had battery issues the day i got it.I was getting around 6-7 hours then, thought it was some issue with firmware checked the battery usage and everything seemed fine expect for few times the android os seemed a little high , so i installed a custom rom , tried sensation and villianrom and a few others .Villianrom seemed to help battery a little but few days in and battery is again draining like fuel in a f1.So i decided its nothing about the firmware and all , maybe i have a bad phone or battery cause its draining like 1% every 2 -3 mins while browsing or doing anything as a matter of fact i get about 4-5 or at best 6.5 hours but thqts rare.I mostly use wi-fi so it definitely uses less battery than 3g . So now my question is ... As i have rooted my phone do i get
The warranty assets as my phone is like 4 months old.I know about unrooting but will that do the trick ?
And btw apart from battery issues , which seem like i have a unique case , my experience with the phone has been amazing this is definetely the best phone on market ;-)
Please respond....and also share your experiences with battery backup of s2 .....thankyou. cheers B-)
*i forgot to add that another thing that i have been noticing is the high battery usage by the display , it sometimes is as high as 80% even on low brightness to which i have found no cure...no matter what i try it lowers sometimes to about 30% or more and is back again to higher, this has furthered my doubt that i have a faulty piece. Pls comment.

I'd say 1% every 2-3 minutes sounds about right if you have screen fairly bright.
Did you do a back up before installing custom rom?
If so install original rom back, then I think you need a usb jig, which is available from ebay. This will reset your custom binary counter so the warranty peeps won't know you've flashed a custom rom at some time.
I'm quite new to this so hopefully someone else may reply and correct me if wrong.

Display uses the largest amount its relative all the figures say is that of the battery percentage used display has used xx amount . Could be battery used 5% of that 5% display used 50% as little else was used .

on regular use, my batt wear off in a day or a day and a half, but when my kid play a HD game, the battery drained in just 3 hours.
I've only tried 2 custom roms, miui and criskelorom, and I think using criskelorom combine with neak kernel is my best so far
I used the trick of battery calibaration by ram3n and battery seems to hold up a little better. Betterbatterystats was really helpful as well as battery monitor and cpu spy . But still i guess yhe phone will suffer on heavy usage or even medim .

Don't talk without knowing what you're saying. As desperate as he is, making a joke would lead to him taking it seriously.
Anyway, calibrate your battery by CWM or just let your phone charge to 100% full. When it SAYS 100%, it doesn't mean it. Leave it charging for about 1 more hour after it says 100%.
Dont be too serious man...
hmm.. that strange.. i'm using infinity v2 by nims11 but doesn't face such problem.
tried using battery calibration didn't work and potentially made it worst, how do i do it in cwm because i read that's the proper way of doing it

Infinity is based on cm7 roms. Cm7 is a battery sucker. U can try SGSII by robinandroid. It is based on stock, but gud battery life.

trying that method tonight.. wish it would help extend my battery power much further than 1 1/2 day..
The information is really screwed up. First my phone was just sitting there overnight at 90 % woke up and now it was about 50%. Phone was down to 17% plugged it in to charge it jumped to 60%. This is really infuriating and i cant even get a hour on moderate usage. Tried calibration didnt help or did something wrong i really dont know i give up

Battery percentage isn't that accurate. You need to see how long it actually lasts, mine goes down to 80 % in the first 1/2 hr of 3g use then stays there for a while, but in the end i can have it last for 17 hrs with pretty high usage. Try and see! And remember battery is fully charged when in settings/info/ status is displayed "charged"
Sent from my Galaxy Ace on Ice Cream Sunday Final
mine only get 8-10hrs normal usage. go down to 80% fast, slower down to 40%, and 20%, but much much slower down from 15% to 5%.
touchdown sync every 4 hrs, internet browsing, whatsapp, twitter.
on the battery use, its always cell standby, phone idle, and display take top three.
you can save the battery for about 24hrs when you use 2G only. with 3G, i don't think so. (I haven't tried this tweak http://forum.xda-developers.com/showthread.php?t=1436367 ).
Try charge to full 100% with the phone on...about - status say full
Power off, enter cwm recovery not while phone on enter cwm manager, use the home+power button method
Wipe battery stats, power on the phone (usually battery now 95-97%) then charge it to full 100% again...unplug n enjoy
I get 17 hour with this method with heavy usage...

doesn't work for my ACE.
when phone ON, I charge it until 100%. then I turn off the phone, and keep charge it until it say FULLY CHARGE. go to CWM, and wipe battery status.
my ACE's battery still run for 8-10hrs only.
or may be my battery need to be replaced with the new one...
You don't have to wipe battery stats every time... after deleting them you have to do some full charge/full discharge cycles. If you don't do this the calibration won't be useful.

Hi all, after a lots of pots from a lots of users claiming their battery is great or their battery is ok and even that their battery is a crap... I decided to open this thread to share my opinion with you all and see how many of you think like me.
Here it comes:
For me, BATTERY LIFE is how GOOD-OK-BAD our battery behaves and how much it lasts WHILE USING THE PHONE.
Having looooong periods of deep sleep is just the Stand-By 640hrs that Samsung itself offers with its ACE.
Under heavy use, ACE is supposed to last at least 11hrs using 2g and 6hrs using 3g.
Me just quoting Samsung and GSM ARENA
Click to expand...
Click to collapse
If you do the math, most of the people that claim to have a HUGE battery life have their phones on DEEP SLEEP (Stand By) MOST OF THE TIME, plus they don't use 3g but WI-FI.
So, when they say: HEY BRO, I unplugged my phone 1 day ago and my battery is still at 30% and then they put a graphic on it you can see that about 20 hours the phone have been deep sleeping. Then you use it and PUFFF!!! A huge percent down...
I don't know if you know what I mean, english is not my first languaje... But what I'm trying to say is...
Battery life is most of the times the same WHEN USING THE PHONE!
Dude stop worrying too much abt battery... Simple battery rule. Charge it when its less than 20%... Let it drain by its own.. Then charge again... There s something called life explore it...
WOW!! What a superb reply... Great, wonderful, splendid...
You're so wise... OMG I can't even believe you took time to reply my request... Thank you Oh Lord!!!
Sigh!
My battery drains so fast on my home wi-fi I tend to browse whilst charging for most of the time (I'm sure it's not recommended). Wish I knew where people get the improved stats for wi-fi over 2g/3g from.
Of course samsung is gonna claim great battery life, they have to sell.
On my experience, i use the phone constantly with 3g for whatsapp and music all the time. I still charge it every night and thats ok. Its a smartphone, a micro computer. Unplugg your lap top and see how long it lasts! If you cannot get a day of battery, youre using your phone too much. The biggest battery hog is your screen, turn it off when not using, lower brightness, dont use 3g and 2g at the same time. Otherwise, get a stupidphone and marvel at your 5 day battery life.

The point about WiFi/3G/2G and battery stats is that if the phone isn't having to work hard to get its connection then it won't drain so much battery. So for example, I have almost no 3G coverage and no WiFi hotspot for miles, urgo if I have them both on the phone will search hard for them and drain battery. I have only 2G allowed and that works for me.
Technically if I had a WI-FI hotspot I should use that because it should provide better coverage than either 2G or 3G, and so the phone won't have to work so hard to get connectivity.
How strong is the signal for your WI-FI, is it very changeable?
I sit about 2m below it and it locks in seconds, varies between 2 and 3 bars on indication. Perceived drain is battery falls from 100% to charge warning in 3 - 4hrs approx.

Data switches off automatically when you are connected to the internet thru wi-fi!
my ace drains battery fastest when i play games,when playing any game 10-15 minutes my battery drains for like 10%
i have good battery life ,,about 36hours when using wifi
the problem of my battery life only happens when the phone is on. I've tried turning it off for a few days and the battery held up too long. So my advice for the battery last long, its always keep the phone off, and use it to shoot on someone's head (devs?). You may even withdraw the battery, lasts longer without recharging.
I suggest that someone makes a rom that doesnt work and keep the phone off, and we will have long battery life

In my case, I've had the best battery life duration with StockRom Lite, AceOne (this seems to fly in my phone).
The AceOne rom seems to "survive" between 16- 18 hours in my chase listening music, checking some emails with 3G (not 16 hours, time by time).
I've installed a rom made by Nathan (TouchWiz) and I was worried about the battery's duration, but since I've installed nims kernel it works better, I'm gonna view how it works
Hello all
I am using Mega 5.8 for 15 days now, everything is great. . Battery too is fine works for the whole day and some more but I find it strange that after reaching 20% the battery dies within minutes and phone shuts down. I thought that might be due to new battery but after 10+ recharge cycles this behavior have not changed.
Can anyone confirm that its a common thing with Mega 5.8 or there's some issue with my device.
Also while we are at it any idea when we might get 4.3 update for Mega?

Thanks for the heads up gx3k , but just to clarify i am not new to rooting . Have galaxy S2 which is full blown modified .
I downloaded battery calib app and deleted stats like 10 times...tried to manually delete the stats bin folder....but nothing has worked . I feel the culprit is the rom .
Haven't rooted the phone but don't believe this to be a calibration issue.
May be its firmware but how to confirm unless we get an update.
Sent from my GT-I9152 using xda app-developers app
Same problem with me
Just try this . One you are in middle of your discharge like around 50% just remove the battery for 20 secs and put it back . You will see in battery you have already lost 10-12% of battery . I think this is the case of either wrong battery reporting or bad batteries. Just have to wait for a custom rom to cross check this .

Same thing here. Already tried calibration. Didn't help.
Was charging it. Removed it from the charger at 60%, I removed the battery and put it back in. The battery % then showed 74%.

2.drain your battery to zero
3.short all your battery terminals to make sure your battery is totally dead..
4.then charge your battery to 100%

Whatever you do "DO NOT SHORT YOUR BATTERY TERMINALS UNDER ANY CIRCUMSTANCE" That's a fire hazard. Lithium Ion batteries can generate massive heat very quickly and have been known to explode on occasions.
Practise good battery management by charging your battery whenever possible and keep it on charge for as long as you can. This will condition it to give maximum performance.
Remember you can't get a battery to give any more power than it has from the charge you give it.
Calibration does nothing to the battery it only allows the software to monitor more accurately.
Lithium Ion batteries should never be allowed to discharge below a preset level as they will then die and will not charge again
lol im about to create a thread about this issue, i thought its only me who experienced this issue,, i've encounter this problem as well,, everytime the battery reach the 15% or the low battery warning, it drains very fast from 15 to 1% it just like about 2 minutes then my phone shuts off due to very low battery level
oh yea,, try the *#0228# it shows the real battery %. in my experience,, from 40% battery suddenly drop to 18%. btw for the calibration apps from the playstore, it just delete your batterystats.bin which have no benefit at all. anyone who encounter this problem please share your experience
I installed Battery Notifier and adjusted the low battery alarm at 25% . It is just a workaround but it serves the purpose.

Hardware or software I don't really know.
As I use the mega 5.8 as my daily phone I see to it that I dont go below 20%. And evry other day or a maximum of 3 days I always recharge my phone. Perhaps other users have a similar routine so very few if any, complain about the issue on this thread.

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? ?
