Hello
I've been having some battery problems with my sgs2. I've bought it in june of 2011, it is my first smartphone and I was immediately pleased with it. great phone, everything working properly. since it was my first phone I was a light user and the battery could last me 2 days, sometimes it even got to last 3 days. However, at the beginning of the year I felt a sudden drop in battery performance, coming to last only 12-15 hours with light use. by this time I became more of a medium-heavy user and under "normal" use the phone would be dead at 10 hours, maximum.
I bought a new battery, official samsung 2000 mAh, and the performance became slightly better. It would at least last a day of work, but the performance was never as good as the original 1650 mAh battery when I first bought the phone.
by this time I began experimenting with ROMs, ressurection remix, miui, and now pfittech. but as time passes the performance is always dropping and today something strange happened. I locked my phone at 17% of battery, and after a while I checked it and the battery was at 18%. I checked again and is now at 19%. Right now it's 21%. What the hell?
can anyone help me? any help would be much appreciated.
p.s. i've tried calibrating the battery and I've read in the forums that on JB it's not necessary because the phone now clears battery stats when they reach 100%. I've also changed the stats with extweaks to absolutely no effect. I've been reading many topics on this but nothing quite seems to fit my situation.

Thank you for your advice I will try that. I'll let you know if it works. btw, when you say kill the battery you mean let it drain to zero right? sorry if dumb question, I'm a newb at this hehe

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 .

you tryed installing betterbatterystats and check which app causes wakelocks? most apps that cause battery draining wake up your phone all the time.
there is a free version of it on xda

I have cm9 so of course my phone consumes a lot of battery but sometimes it uses 2% in a night, but just a while ago i had 5% left of my battery, i go to get the charger and when i come back in 30 seconds, I have 0% of my battery left

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 .

My Samsung Galaxy S2 Battery drains heavily all of a sudden. I noticed that suspend backoff is consuming battery. It doesnt go into deep sleep either. Using ICS 4.03.I have attached Battery Stats dump file. Please advise.
Hi everyone master..
My tab's battery suddenly running out very fast..I put at home (59%) then go to work. Come back home (20%). About 12 hour 14 hour interval loss 39% without processing anything.
Also, the wifi,bluetooth GPS is disable. Do you know what is the problem. I didnt have this problem before and suddenly feel the battery getting die faster on last saturday.
Can i claim from Samsung? and what is the procedure of claiming?
really need your consultation.

Did you just flash a rom, kernel or model? You usually have to let it go through a few battery cycles before the true battery life is known.
You can also download better battery stats from xda, and cpu spy from play store to see your wakelocks and if your tab is deep sleeping

Hi Bro, thanks for your prompt reply.
FYI, I didn't do anything on my tab, is just that its battery suddenly drain very fast. I will try the suggestions of yours.
rapid battery drain
Hi,
I was having the same problem on my unrooted Tab 10.1 a couple of weeks ago. This progressed to it barely keeping up with the amount of battery discharge during use. At first I assumed the cord was wornout. B ut when new corde arrived no better. Now determined to be bad female end on tab itself as charging was positional, while it still worked at all. Upside? New tab arrives tomorrow. Hope this helps.
I've been using my s3 for the past one week and my device shows 99% assoon as i remove my charger! i've tried changing the rom, erased my Battery stats, recalibated my battery using playstore apps. even though it shows 99%. please help! by battery life is worst!
All GS3's are like this only. The battery actually never charges to 100. Its purely cosmetic.
Please tell me you've actually tried searching for this before posting since there are literally dozens of threads and discussions revolving around it.
Physically it's very simple. If a battery is 100% full, it's as full as it can get. This is not true for everything but for most consumer-related stuff. (Airplane turbines, reactors and other industry-machines see it as a maximum value for long-time usage but can go quite a bit above)
If you unplug it, your phone starts draining battery since -surprise,surprise- it needs power. So the battery cannot stay at 100% if a (however tiny) part has been removed.
Phones that remain at 100% after unplugging for some time are lying to you to make them look better. And you don't want a manufacturer lying to you, do you?

Better check of you have rogue apps in the background or your screen brightness, my batterylife is quite good (about 2 days with medium/heavy) use. Running stock firmware.

That's perfectly ok. Relax Been discussed here already...
PS absolutely no need to calibrate the battery
This happens to me as well but don't fret over it.... Calibrations should be done regularly but not overly or it'll stress your battery more than necessary.
You do not calibrate your battery regular the year is 2012 not 1995 .
Battery auto calibrates itself use it ignore it .

I'm amazed how people can get nearly 2 days with medium usage. Do you have any apps installed? How many hours screen do you get?
It seems it's pot luck with battery life..
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 hard reset it once again. Now is on charging. After that, I will provide you a screenshot with battery stats. Thank you for your help! I try to borrow an othe battery from an other LG L9 phone to see if is the battery or the phone! I hope to find someone with that kind of phone.

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?

I guess your signal quality isn't good enough because cell standby is eating up more than 40% of battery. Cell standby in my phone is only around 5%..

I removed the sim card, but in flight mode is the same problem... The last solution is to change the rom with a custom one. Any recomandation?
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.

your screenshot shows 1hr21m on battery with 97% left. whats the problem? charge phone to 100%. use normaly until you get down to about 10% and then take a screenshot of system settings/battery and post.
Punctuation is your friend. One lonely question mark at the end doesn't count.
