Samusng Galaxy S2 horrible battery. - Galaxy S II General

Hey guys, I recently got a Samsung Galaxy S2 (over 2 months ago)
At first it was really good with battery life, lasting over a day with medium use.
It started to get really bad, draining down from 100% to 50~ over night with no use at all.
I searched the problem and came across these forums, which said 2.3.3 was a problem sometimes.
Now this is also my first android phone, so I'm not sure exactly how to do all the tinkering around with it. Long story short, I found that changing to 2.3.4 helped a lot. It did, for 2 days, now I'm getting the same problem again. Maybe I didn't do it right? Need help! (also this forum is huge, not sure if I'm in the right spot)

Have you tried flashing a custom ROM and kernel? Pick out a ROM that you like and then install a nice kernel like Speedmod. Lite'Ning ROM v6.1 and Speedmod T39 together really increased my battery life.

Is there like a "how to" section on this site somewhere?
As I said, this is my first Android phone, so I'm a little lost as to how it all works

FOLLOW INSTRUCTIONS AND LEAVE ODIN AS DEFAULT. DO NOT UNPLUG USB CABLE DURING UPDATE OR YOU CAN BRICK YOUR PHONE. YOU ALSO NEED SAMSUNG KES INSTALLED FOR USB DRIVES CLOSE KIES WHEN USING ODIN

Thanks for the help guys.
I "think" I rooted my phone and got a version of 2.3.5, which is also supposed to be better on the battery?

just download 'start up manager' from the market, disable useless stuff that is not need ed, I get more then, a day now worth normal use.

Or also get titanium backup, and freeze all the useless crap on the phone that you dont use. I did that and it went from 7% every hour (despite the fact that there were no wakelocks) down to 0.5% every hour
EDIT- on standby/very little use, that is.

Also after you flash charge your battery to 100percent and calibrate your battery there is a good free app in the market

Well if you're using its smart phone capabilities it will really drain quickly. Specially when on data. What I did was to get an extra variety and an external battery charger-best investment for this phone ever.

You can also see what drained your battery by going into battery usage: Menu - settings - about phone - battery usage. or create the shortcut on your desktop.

download betterbatterystats to check what processes are burning your battery and stuff. helped me a lot, this app.

Given that you are getting decent performance for a bit, which then drops off, I'd say it was far less likely that the cause was the hardware or the ROM and far more likely that it is something you are doing with the configuration or software.
Try removing any widgets you have added - does that improve battery life? If so, add them back one at a time until you find the culprit. Also, make sure you are not signed into stuff like Latitude - that is an absolute battery killer.
You have seen that you can get decent life from the battery, now you just need to work out what affects that.

It was the 2.3.4 OS draining the battery. I wouldn't touch my phone, and in 8 hours it went from 100% to 20%, with the status saying Android OS 100% in battery usage.
Now I'm on 2.3.5, battery is at 95% after 4 hours.
I'll give it a few days, and see exactly how it goes and if there is a substantial difference in battery life in relation to use.

I almost had the same problem with the battery but i flashed omega rom and so far i have no problems! I always have wifi on when i am at home and 3g when i am not at home and the phone can run up to 2 days!

Have you tried doing a basic search and looking at one of the 100's of other threads crapping on about battery life?

galaxy s2 i9100 Battery Problem!
I am using Samsung Galaxy s2 for a while and I am facing an extremely low Battery Back up. Around 9-10 hrs to the max. I got the battery changed from the Samsung service center and have tried changing alot of different firmwares.
KE4 -> KE7 -> KF3 -> KH3 -> KI3 -> Simple and clean 1.2 KI4.
Nothing works.
I am attaching my "Battery Usage" images along. Please find a solution for me. Thank you.

Calibrate your battery, but you must have root access. When you have root than load the calibrate app.

i am quite heavy users on my sgs2 at first i had battery problem lasting only 5 - 7 hours... i got juice defenders free version from market and well it didnt boost my battery life to 48+ but it did made me last 1 and half day

New battery stats!!
Alright I experimented with the battery to check whether there is a problem with my battery or my firmware/kernel.
I tried the same battery on 2 different Galaxy s2. Battery stats below :
DEVICE 1:
Firmware : Stock KF3 Rooted
Kernel : Stock KF3
Battery Usage : 14hrs
Display : 45mins
Voice Calls : 1hr50mins
Battery remaining: 50%
DEVICE 2:
Firmware : Simple & Clean v1.2
Kernel : SpeedMod k2-18 test3
Battery Usage : 12hrs
Display : 45mins
Voice Calls : 2hrs
Battery remaining: 19%
Now in the above case I have used the same 1650maH battery in 2 different handsets. So why so much difference in battery life on an almost similar usage when I also made sure that the Brightness levels of both the phones also remain same.
Please help me out on this.

Awful Awful battery life since Darky's ROM

I have always had stock ROMS with my i9000, ending with JS7. I read the battery problems people had and I always counted myself very lucky that my phone had a pretty decent battery life.
Daily I would SMS (a lot), the odd phone call, quick blip on the internet (3g), lots of angry birds and doodle jump! I would get at least a couple of days before it went into the red.
Then I made the big mistake of installing Darky's ROM, it looks nice and feels a bit snappier, but now the battery is in the red in the evening after a full nights charge. This is even after severely curbing my phone use to try and extend the life. I have tried all the wiping tips and tricks too.
Same apps, different ROM. Darky's is an absolute nightmare for me and I will be going back to stock.
So is the ROM just another variable in the mix of battery issues, or the main offender?
Hello. I've the same battery drain, and I think it's very annoying when at evening you need to charge it again without using strongly the phone. Otherwise the Darky's rom, (I'm on 9.3) is very nice and marvellous, but this battery drain issue makes it worse.

This and:
have you let the phone drop below 10-5%?
Flashing screws up the battery indicator (how much depends) and it calibrates itself while in use. Letting the battery fall, or even the phone shut down by itself can speed up the process quite a bit. This helps only if there is no battery hungry app that's eating all your powrz though.
I haven't tried to see if there is an app sucking the life out of it because I never had any issues under the 3 or 4 stock roms and I haven't d/l any other apps. The battery deterioration started instantly I flashed with Darky's. I don't know which gallery it is, it came with the d/l. What ever it is, it doesn't work! No, didn't use the configuration tool.
I must admit I haven't let it run under 10% as I want my phone with me working. But wouldn't this manifest itself when I updated the stock firmwares?

ok mate, firstly search the market for the Darky Rom Configurator, shoudl be easy to find, you shoudl be able to reflash without wiping all your apps, run the config app first and pay special attn to the 'Lockscreen wallpaper' of the tool, there aint many options to choose. Got the gallery drain bit mixed up, sorry tired
If i was on my own PC id give a bit more detail but its pretty straight forward.
Im running 9.3 and get a full days mid-heavy use, i normally go to bed at 10-15% which is fine with me
cheers for the advice mate, I've just grabbed the app so I will do the flash in the morning.
I will report back my findings!
Just a thought but Darky's Rom uses JS5 and wondering if has something to do with the modem? Just a theory but wondering if you could replace back to JS7 and see if that helps. Just a thought. I'm used to a day's worth of battery myself these days.
The faster you make the phone go the more power you use darkest Rom are ok but messed with too much
I got really bad battery life for the first few weeks using darky. But now the battery life seems to be longer and more stable and average. I did do calibrations a few times tho.

You won't get better battery with Darky ever.
I played around quite a lot, 9.2, 9.3, calibration, fresh system, darky rom configurator, different kernels, lagfixes, no matter what, my battery drain was mad. It's a quick and smooth rom, but that's the downside of it.
I switched back to Doc's rom via kithen with same kernel, and quess what? No calibration, no playing around, nothing special I did and battery life is brilliant! Of course it lags here and there, that's Doc's drawback(no lagfix applied tho)
You will often find that if you flash a number of roms you get battery drain . Apart from the actual rom itself you need to flash to a clean firmware reset battery stats use a suitable modem charge battery once using bump charge method then wait a few weeks for it to settle down .
I am using rom kitchin since Darkys killed my battery life months ago .
JPY and JPY modem no complaints about excess battery life .
But i did flash back to clean stock before custom rom and wipe everything .

but this is true even if i use a kernel mod.. instead of a full flash? i think that a stock rom with custom kernel made for battery lasting is better... or not?
Have u all tried Battery Bump Charging?
Hi, I am not a Galaxy S owner but I am doing a research on this issue for a friend.
I am a Milestone user and I am a ROM slut (I flash many ROMs back and forth)
So I am very familiar with cases where after flashing a new ROM, your 100% fully charged phone is actually 60%/
Here is a posting on a few ways you can do a battery bump charge. When you perform this battery bump charging technique, u will be surprised to see that your 100% fully charged battery is actually not 100%

Does anyone have any quick advice to fix this? Bit under time pressure due to job at the moment and don't have much time to research this. Any advice to fix this easily and quickly?

I too have almost the same problem with Darky Rom 10.1 - but I've heard that it has been fixed in the new beta version. I'm gonna flash it at the end of the week and after a few days of observing, I'm gonna tell you the results.

It's been through quite a few cycles.
I think I figured it out.....I think it was Skype. If you sign in the app is always on...it doesn't have an exit feature. There is, however, an app to close it. I used it and got normal battery life today!
We'll see if it keeps working like it should.
So I've upgraded to 2.3.4, (Ficeto.Deodexed.XXJVP) and Android OS battery drain stopped. Now it shows 70% battery usage on display (before it was 70% android OS). I recommend updating your system too
with darky on medium use never had more than 14 hrs )
I've given up for the moment and gone back to Darkys 9.5
Now at least I can get through one whole day and have about 40% left

Are you willing to flash the rom again? or you can try to use the speedmod 15g t11 for the kernel to replace the JVP kernel.
it's said that when you use the USB connection to your PC, you need to reboot it. So this battery drainage will not happen.
In the ROm 2.3.3 JV5 and JV6 for Asia, I do the same to keep the batter alive.
Try backing up everything and then factory reset phone. Generally this happens because of a few unwanted applications excessively using ur processor, in turn draining battery or there may be a malware that stealthily connects itself to the net. This will almost certainly cure the disease. If it doesn't, then there is a serious defect in ur hardware or some of ur system app required for properfunctioning of the phone is corrupted, causing excess pressure on the processor
It is a big problem to everyone, I charge twice per day for this.
Calibrate your battery
Let the battery go down to 0% and turn off
Then turn the phone on, it'll turn itself off again cause battery is low
Keep doing this until its totally 0%
Plug in the charger, charge it to 100%
Turn the phone on
Download SGS Tools from the android market place
Run the app
Go to "scripts"
click delete battery stats
Unplug charger & you're done
battery should be more stable now

check what you have in the background
close them down if they're unecessary
I get through the workday with only 10% loss
If you have an really old SIM card, try and replace it with a brand new one. This may also help. I had bad battery run time with two LG Optimus 2x phones (about 10 hours) and not so stellar 20 hours with the i9000. Finally I stumbled over some advise to replace old SIM cards. Since mine was over 12 years old, I ordered a new one. It is not gonna change the world, I know, but it was worth a try .

what worked for me
Hi
I wanted to thank for Zoe Rom on its thread, but i cant write on developer's threads yet (altough i clicked thanks button there).
Im glad i finally got rid of my memory hogging default rom and now i have a properly working phone again!
Also i wanted to reply there (to some people also complaining about battery endurance on GT540 on Zoe Rom) how i fixed my battery main problem.
Pic of current battery drain:
http://postimage.org/image/d8o8uusd7/
As you can see i am aproximatelly at 50% battery after 1day and 11h of not charging.
I had 2 problems:
1- Battery lasted aproximatelly 5 hours on standby (and i mean i wouldnt even touch the phone and the battery was gonne after that time)
2- During intense battery drain usage, the battery was reporting to have less energy than what it actually has.
1st problem solved by simply turning off the wireless after im done with using it. No idea how could that be taking away so much energy, but it was. Somewhere during the period i was using my default rom i got used to have wireless always on, and my battery on the later times was going away faster than normal (i also like to listen to music on the phone). At the time i didnt correlate the 2 things, and i just put in my head that it probably was the battery dieing on me. It wasnt! The wireless (i suppose because of the Sync function also being on) has been draining my battery like mad between charges.
2nd problem persists. As you can see on the pic, those 2 spikes down correspond 2 diferent aproximatelly 1 GB file wireless transfers with Wifi File Browser app. This transfers (PC->Phone) make the phone CPU have to unzip the two 1GB files to the SD, so they are very CPU and SD card read/write intensive (i can force this battery drops with other instense battery use like playing a 3D game for example). The thing is if during that temporarly drop on the battery level measurement, the level hits 5%, the phone will shutdown. But to be honest, this problem is minor comparing to the 1st one.
There is one other minor problem with my battery, wich is the reading being inconsistent (drops 10%, then gains 15% then drops 5% again etc), but is this a problem at all?
I read a post of a guy that had made extensive testing to his battery cycles, providing loads of graph of battery levels (cant find link) . I didnt read through all of it, but i remember the guy saying something in the end like "Dont be too paranoid with your battery levels, as they arent accurate. Instead use your phone normally and you will gain an idea of how long will it last with certain types of usage"
By the way, he also said for people to just charge their battery whenever they could/wanted as it has no negative impact on battery life. I also read a bit of a paper on lithium-ion batteries stating the same, so no more forcing full-discharges for me!
One last thing! Deleting the batterystats file is as simple as disconnecting your phone from the charger.Why? because that file serves solely the purpose of suplying the UI with info of the battery drain usage on the current battery cycle.
http://www.xda-developers.com/android/google-engineer-debunks-myth-wiping-battery-stats-does-not-improve-battery-life/
And you can confirm this if you unplug your phone while looking at yout battery stats.
I hope this helps
PS: pls notice that it could have been not the wireless itself that causes the battery drain, but some service using the wireless. Finding this would require more extensive testing.

Update
Hello again
I just wanted to give an update on the situation since i noticed this post is linked from the Zoe Rom thread.
Two days ago i bought a new battery, an unbranded one (cost me 15€ here in Portugal). The shop had a legit LG battery for 37.50€ but i tought it wasnt worth the money. This battery has the same specs as the original, except it is 1300mAh compared to the 1500mAh of the original.
I dont have any battery related problem any more. Yesterday i woke up (100% battery), unplugged the phone, let the wireless on all morning, listened to 2-3 hours worth of tunes, browsed the web a bit, tested some messaging apps etc. Today i woke up, didnt charge during the night, and im sitting on 45% battery. Wish i had gotten a new battery sooner lol
With my old battery the phone wouldnt shutdown. It would always automatically restart. I had no ideia a malfunctioning battery could cause this.
I've have had similar problems with the battery on my GT540 with all cyanogenmods - 2.3.7, 4.0.4, 4.1.2. There were no such problems with original 2.1 I think it is the price for the newer versions, I can live with that, I don't have to buy new phone

Battery life decreasing...

Ok, so I've had my SGN for little under a month for the first few weeks I had it I was getting great battery life, almost 6 hours screen time full day of battery etc.. Then I rooted it using one click root because I wanted some more access, since then battery life has seemingly been slowly getting worse. I have tried changing back to stock roms and custom roms, I've fully discharged the battery and charged while it is off a number of times but I'm down to 3 hours screen time and can't get a full day out off it anymore.
Is this something to do with the way I rooted, what can I do test and try and get back my battery life, this is the main reason I got this phone..
It's hard to say if it was the first update I installed/rooting or something wrong with the way I'm charging but it's certainly decreased even on a stock ROM without installing anything..
Anybody else encountered this?

I have the same "feeling" with my Note. I have installed System Panel to monitor usage but I can't find anything specific that seems to be sucking the power. But it certainly "feels" like my battery is draining faster than before.
It's probably as the phone gets older, you install more & more Apps. Some of these are probably working in the background sucking your battery.

Even with a clean stock rom, it doesn't seem as good as it was without root or any updates.. Wish I remembered what the phone came loaded with, I'd give that a go..

Try Rocket Rom v17 or latest XXLA1 firmware and your battery life will come back even better than before, just me
Same "feeling" here! I will try LA1 firmware....
So I'm currently sitting on 4.30 hours screen time, 15 hours uptime with 20% battery remaining.
Running la1 firmware and la3 modem, been using stock browser. Taking lots of photos with flash too, so I think this combo has rectified my issues but I know there's more potential as this is roughly the same stats I got on my dhd, although that was underclocked and tweaked to the clappers.
Faith is resetored in my device, hopefully it improves.

Battery drain

Hello!
I rooted my phone as of yesterday, I charged it all night and when I took it off today the battery went from completely full to dead withint 3 hours of no use. I did not use the phone at all.
Any ideas?
If you just rooted your phone, you should not have battery drain... Try to temporarily disable root (with Voodo OTA RootKeeper for exemple)
Use better battery stats to nail down which app is causing the drain
Did you try wiping your battery stats in CWM - advanced?
There's also an app, Battery Calibration, on the Play Store that may help with that.
Not uncommon to get weird battery readings after changing rom's or rooting.

I rooted my phone as of yesterday, I charged it all night and when I took it off today the battery went from completely full to dead withint 3 hours of no use. I did not use the phone at all.
Any ideas?

This is soooo strange. Not a normal behavior!! Before you root your phone, how the battery lifes goes??? Are you in a stock or modified ROM? Wich kernel are you using?
I faced this issue a couple weeks ago. Android S.O was the culprit and it was driving me crazy. I was using a custom ROM (RemICS-UX). I solved the problem returning to stock and erasing everything, then i reflashed the ROM and the kernel, in my case Devil3 0.79. If you want to give it a try!!
After that my batterys life is pretty fine, during at least 2 days!
Feel free to ask anything you want! Cheers mate

Go through a couple more full charge cycles, if android os usage isn't very high then, it should be fine.
Edit: on second thought, draining the battery without use in 3 hours is extreme, and would suggest that the CPU is running at max speed all the time. If it doesn't solve itself or improve a lot after a few more charge cycles, reflash everything.

Did you just root your phone or did you flash another ROM? Some ROMs have horrible battery life.
The stock battery usage monitor (Settings>Battery) should be enough to tell you what ate your battery. If it's a particular app you're running, try disabling that and see if it improves. If the usage is mostly "Android System", "Mobile standby", or something like that, then you have a tougher problem. The free app CPU spy will let you know if something is keeping your CPU usage high. Better battery stats is pretty cheap and will give you much more specific information.
+1s for BetterBatteryStats and waiting a few charge cycles before judging/debugging your battery drain, especially if you changed your kernel to root or flashed a rom.
I find that after flashing a new rom or kernel my phone, the battery level shown in recovery mode is higher than in the rom's settings, for a couple days. (You can see batt level in semaphore's recovery). I once dud a lazy search about this and found nothing, but I figure that's what is meant about waiting a few cycles gir your battery to calibrate.

There's no such thing as "calibrating your battery". It's a myth. Wiping your battery stats file doesn't do anything other than reset the tracking of what's using power. It doesn't magically fix your battery meter. Flashing a new ROM doesn't leave left over data, again a myth.
Battery life is never consistent after flashing because your ROM needs to "settle" for a day or two first and during that time your ram and cpu usage are all over the place.
The rest is a placebo effect.

I think I may know what is happening to you as of now. Try to bring up the Battery settings if you are on ICS and take a screenshot and post it here. If my 'spider' senses are correct, your phone did not go to 'sleep' and remained awake.

Currently I'm experiencing a huge battery drain too. I used both tools which where mentioned here in this thread and when the drain occours, CPU spy reports that my SGS didnt go in deep sleep at all with turned off display, it was at least at 100mhz all the time! I attached 2 logs from better battery stats and it seems like the NotificationService is causing it?
I'm using JW6 PDA JW4 Modem and JVC CSC in combination with the MNGB 0.5.8 Kernel.
Definitely, now you got to find out what is causing it!
