Hey guys,
I'm a new Galaxy S2 owner, since I was able to get a real / near new condition galaxy S2 for cheap I'm having an issue with screen on. I have seen loads of posts, tried loads of things, but haven't been able to get over 4 hours screen time. Now before people say 4 hours is enough, it isn't. I use my phone for everything and I need it to last at least 6 hours with screen time. My standby time if I leave it is around 12 hours. That's it.
Now before you go and say go and get a bigger battery. I have. I have the extended Samsung Galaxy S2 Official 2000 mah battery some people I know have been able to get 5 - 6 hours screen time no problem. I'm lucky to get around 3 hours.
It seems screen related and if I put the screen to auto brightness my battery is halved from the 3 hours I get. I just don't get it. I have tried Stock Samsung Firmware, to The latest and greatest Neat ROM. I was able to get 5 hours and 49 minutes some how, once. But now I can't reach anything like that. It's killing me as it is such a great phone and I don't want to get another stupid bulky battery.
Any ideas on kernels? Different ROM maybe? I want to stick with jelly bean but if people can better screen on time with different ROM's I'd be happy to switch.
Thanks for the quick read, Hope you can help me before I just sell this phone again, Which I don't want to do, it's a great piece of tech

Smartphones are battery hungry fact. But im abit like you where battery life is important.
I came across Neatrom, Im now getting 7hrs screen on time. I also use greenify from google play which stops apps running in the background which helps abit.

Hate to say it but I am on NeatROM, the latest version. And I understand they are battery hungry but my Acsend G300 could easily pull 9 hours of abuse. And this phone has a bigger batter and what I was originally told a more power efficient screen :/

Neatrom lite? Is your battery new? Have you done afew battery cycles? As it takes afew cycles to settle. Power saving mode enabled?I highly doubt you will get 9hr screen on time with the s2.

Yeah it's neatrom lite 5.2, battery was brand new and sealed. Battery cycle as in fully charge, fully discharge? I have done every time since I have got the battery. I have power saving enabled. I would be happy with around 5 hours screen time, That'd be perfect. I use spotify in the car every morning for an hour and in the evening for an hour and two and from work related travel. But apart from spotify I use facebook, whatsapp, but that's mainly it, i don't see why it has to just drain so quickly. I also have green power switching off data when I lock the screen and it re-switches it on every 10 minutes to sync my stuff. That kind of helped. But not a huge deal.

Hi guys,
So for the past week or so, I've been noticing really bad battery drain on my GS2, and I think I have finally pinpointed the problem.
"BetterBatteryStats" has told me that there are 2 specific wakelocks running in the background, which prevent the phone from going to 'deep-sleep'. These are the "suspend" and "events/0" processes. They are on for hours, preventing the phone from going into a proper 'deep-sleep', and keeping it awake.
My question is, how would I stop these processes from running? I know for a fact that it is not such a common 'bug', because tons of people are getting >18 hours on their GS2 with moderate/heavy use, while I'm only getting about 10 with light/moderate usage.
So in short, why are the "suspend" and "events/0" processes running while the phone is supposed to be in sleep mode, and how do I stop them from running and draining battery?
Thanks everyone!
Well I don't have that problem so can't say. You should ask it on the BBS dedicated thread,

This is the famous "Android OS" bug, which happens only on SGS2. Search the forum and you'll see quite a few threads about it. There is no solution, but keeping wifi off when not in use or setting is to sleep when screen is off helps quite a bit.

It's not only a bug on SGS2. I've been fighting this problem for quite a while on my Nook Color with CM7. Here's the thread I started.
hmm, I am having this problem as well, I'm used to my iphone, where i can use it all day and still remain above 50% meanwhile every time i pop the screen on my GS2 the percentage is down from last time. its horrible, very much considering going back, I love this phone, but this battery draining situation is out of control for me.. midnight -8:30 i lost 45 percent battery.. screen off..

well for me, installing the siyah 1.8 kernel has sorted it and my battery life is pretty damn good now.
Others will tell you its not fixed and the extra battery life im getting is a placebo. But all i know is i used to get 3 hours screen on time and lose 15-20% battery overnight. Now i lose 2% overnight and get 5-6 hours screen on time. If thats placebo then so be it.

hmm, ok, I will look into kernels, I am using an AT&T SGS2 so its a little different kernel wise. I have yet to find anything in my specific forums though.. just switched from an eperimental kernel to a stable, so maybe this will help
I think I just read somewhere in the Galaxy S2 forum that AOS isn't exactly solved on the .14 kernel (which siyah 1.8 is based on)..... it just merely not include suspend and events/0 into the Android OS count for the battery.....
Anyone can shed some light on this?

is siyah 1.8 better for battery life compared to siyah 2.1 or the newer one?
I tried 2.1, but I still have high android OS.
Using bbs, I see that suspend and events/0 is still around 1 to 3 minutes each day.
I have turned off:
Accounts and sync > background data & auto-sync,
Privacy > back up my data,
Location and sec > use wireless networks.
Any other advice?

Use a 2.3.4/2.3.5 based ROM such as CheckROM HD or Hyperdroid-Androidmeda with Darknight-Siyah Kernel.
I get 3 days of use if i keep data off . With Data on and normal usage i get on average 0.7-1% drop per hour compared to 3-4% of 2.3.3 ROM.I think it's a combination of kernel and ROM that solves the problem.
Earlier CPU Spy used to show lots of time spent at 800Mhz which is what android OS bug does. Now i see it spending 1-2% time in 800Mhz and most of time in deep sleep.
thanks for the reply.
now I am using CRv3.1.1 with speedmod 18test3.
but it seems that from day to day, events/0 & suspend are getting bigger and bigger.
do you know why?
I upgraded to KI3 a long time ago, and froze the hubs + wifi sharing / wifi sharing manager (i never even used the hubs anyways), and what do you know; my battery can now easily last me a LONG time, after 16 hours it still always has AT LEAST 40% remaining, and that is with a few hours screen-on time, data sometimes on, wifi usually always on! I'm extremely happy now!
So in short, for those of you with bad battery life, the least you could do is upgrade to XXKI3 or XXKI4 (they're pretty much the same thing) firmware/kernel. Even completely stock without root/frozen apps is A LOT better than any other 2.3.4 / 2.3.3 ROMs.
CRv3.1.1 is already based on xxkj3, and I have already frozen most of samsung bloatware.
However, I have just found out that kernel is an important factor in high suspends and events/0.
Now I use the previous version: speedmod 17 test 1, and suspends & events/0 decrease a lot.
Hi, I just recently flashed the LPG ICS Rom to my phone 2 days ago. I did the wipe and flashed through mobile Odin. I restored some of my apps and data with Titanium (also uninstalled most of the samsung apps)
I already did a battery recalibration (pulling the battery at 100% etc.) but I am getting pretty bad numbers. Just 7 hours tops, I guess a lot more if I dont turn on the phone but I guess this is really wrong.
Am I missing something? Should I uninstall or disable something more? This exact configuration gave me minimun 12 to 14 hours on a stock not ICS ROM.
Also I should mention that I am using Juice Defender Ultimate with connection intervals of 5 minutes, pretty average settings.
Any suggestions, tips or guesses?
Thanks a lot!
PS. I dont have any strange apps, just the normal (facebook, twitter, whatsapp, Talk...), My display brightness is set to auto.
What really matters is screen on time and you are getting barely 2 hrs and that is indeed awful but in line with all the complaints I've been seeing in the forums.
The update I got was not LPQ but rather LPE (Trinidad & Tobago) which was released the same day as LPQ. I am getting 4.5 hrs screen on time (around 15 hours with my usage habits). This is barely acceptable as I usually got 5 hours 15 min of screen on time with my stock 2.3.4.
Hopefully Samsung will fix this soon, it was supposed to be the other way (battery life improvement).
Soo...
So I guess I'll just have to wait the next rom releases, as it seems that they are improving the rom every new release? Does that make sense? the roms are being released almost one day apart from each other, arent they the same?
In case that for example a new rom comes out tomorrow and the fellows here say that it really improves battery life. What should I do? wipe and install just as this one? or would I be fine without wiping?
Thanks a lot!

Their is no normal battery usage and you have not given battery any time at all to recalibrate .
Just read the battery posts and use Better Battery Stats .
If their is a problem a full wipe is always best .

Ok, so after a couple of days using it.
The battery now lasts almost 9 to 10 hours with normal use. but I deactivated Juice defender.
Now I have disabled all of google location stuff, and some of google services autosync (like google photos and reader). And will turn on juice defender to see how it goes.
Ill update my findings.
Thanks.

I flashed CM9 on my GSII on Friday and ever since it's had 5-6 hours on usage. I've tried doing the battery calibration stuff, seemed to be better Monday and today it had 50% after a few hours of gaming so that seemed normal but then i reset it and it dropped down to 10%. I tried calibrating again and still 5 hours.
I've been using that Battery Calibration app and it game me 40% charge at ~3500mV. I'm not sure whether that is the battery volume but seeing as 100% was 4200mV something seems wrong.
Anyone have any ideas?

maybe the kernel makes the difference.-
But is a fact that GB has better battery management, that ICS

I have an LG GT540 as well with ICS on it and that would get 8 hours regular usage with it. My GS2 get's less then that without me using it.
Ok you compare with other device, i Spoken to Galaxy s2, Ics have bad battery management, in sleep mode.-
But I´m still test the slim rom with neal kernel and have 53% battery after 30hs. with a general purpose.-
try it this rom an kernel,.-
As was already pointed out, bad battery life is almost always a rogue app keeping the phone awake, install Better Battery Stats and CPU Spy to monitor wake locks and deep sleep, if you find a problem with an app keeping your phone awake, uninstall it and your problem will likely go away. Personally, I've been running CM9 and other variants of ICS for months and I get less than 1% per hour of drain while the screen is off and the phone is asleep, this is better than Gingerbread was.

Right, but background sync can still hit the battery, even with screen off. I was just curious.
Ive had days with horrible drain but it was almost always an app doing something dumb and keeping the phone awake, bad cell reception or a noisy wifi router. The trick being to identify wake locks that seem suspicious and track them down.

first of all it should be spelled "serious"
and now if you are coming from a different OS like symbian or ios then here is the hard truth all android phones pretty much have comparatively(to symbian) low battery....
and give it some time,a few battery cycles will improve battery life...
ps:i am on stock 4.0.3 rom my s2 only lasts 1.5 days max only if i don't play games.....

so you are facing problems only after factory reset??
did you install any particular app, maybe that is causing the drain...

I will never use TouchWiz on an android/galaxy phone, I will always use custom ROMS

Generally most people will agree that Resurrection Remix is a very good ROM for battery. But most ROM s that d not use the touch wiz is probably better.

Really? That is so much good news to hear, Can any one tell me what should i do after flashing new firmware in my s2 , Some peoples saying dont delete battery stats files its cause some fuel alert wakelocks and some are saying only deleting battery stats files can give you correct reading actually i was thinking that the cause of android Os high battery usage will be the incorrect reading of battery what you say ?

Incorrect.
ONE complete battery cycle will re calibrate the fuel gauge chip. Once when i cycled my battery it stuck on 1% for over 4 hours. It does NOT give you longer battery life, rather it re calibrates the battery indicator.
OP if you want better battery life try this:
Use a custom rom, or a frankenrom if you like the stock feel, or a rom modded for better battery life
Look into what services are running and remove the ones that are running when not expected
remove the facebook app,
use less widgets (since they use more battery),
choose a darker background (AMOLED screens use the most power for white),
turn down the brightness,
have GPS, WiFi, and Bluetooth off when not needed,
turn off auto updates,
anything that automatically checks for stuff, turn that off or increase the delay,
Use a kernel that supports under-volting and under-clocking. You have a powerful phone which rarely needs to use all the power. Under-volting and under-clocking can help you get even several hours longer out of your device without a noticeable impact
Turn off those damn task killers. Its more efficient to not have a task running than to close it every 5 minutes and have it auto start up again. task killers were great for android 1.3, not so great for 4.0
In my class there is one other guy with an S2 and every day i hear his battery beep at him that its dying. I can go about 2 days of similar usage with no battery problems. Why? Because i spent time and effort to learn why my battery was draining and how to make my device run as smooth as i can.
TLR Do some research. If you want everything given to you buy an iPhone.

Brother i am suffering from a very sereus problem i dont know my android system and android os battery usage goes to high i celibrate my battery many times but its not working for me
zain, dont fret yourself over the battery backup duration. With frequent usage, you will have to charge twice a day at the most. Your battery will still last 2 years.

Give up on Samsung ROMs and try some custom ROMs
Battery life on ICS is worse than gb but I can get 3 hour screen time and the phone lasts for over a day which is more than fine
Sent from my GT-I9100 using Tapatalk 2
quick tip
kernel settings or rom settings and quick qovernor setting switch it to ondemand
4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this
5) Read about jb settings/issues.
Sent from the little guy
Hi OP,
I haven't been on the i9100 for that long, but have also been annoyed with short battery life. As have many others from what I read. A 12% drop over about 8 hours of sleep, I'm sorry to say, doesn't seem that bad actually for an SGS2 with stock jb 4.1.2 and stock battery.
Personally, I tried different lightweight ROMs that are known to spare your battery. The advice to turn off 3g and other core functions never made sense to me, as I want an operable phone, not some sort of deflated piece of junk.
After reading on xda I went through Slimbean , Liquidsmooth, and other ROMs to see if they would increase battery life.
My current ROM is NeatROM 4.8, which actually seemed to give better results. Please note that this is purely subjective, though, I have no fancy battery analyses to back up my statement.
What REALLY helped was getting a replacement battery.
I tried Qcell 1950 mAh batteries. Stay away from those. They are clearly not 1950 mAh. Now running with a genuine Samsung 2000 mAh which is worth every dime.
Now I imagine you would be frustrated having to buy a new battery just because you updated your firmware and I do understand. I never owned the SGS2 before jb, so my choice was simple I guess. That having been said, though, the 2000 mAh battery really turned the phone into a whole new sort of usable. It easily lasts through the day even with regular use.
Just my 2 cents.

yea.. u said it...even i have tried several custom roms ( NeatRom, WanamLite,RR etc) all give 15-19 Hrs max.. and this also by tweaking all the settings..
S2 is a undoubted beast, but the cost in terms of battery is very hight..my previous Android Motorola Defy was a Mammoth in itself..huge custom fanbase and loads of ROMS + Awsome battery.
Any ways i got no regretts for having a S2..but battery s a lil concern..
Currently am on Asnet MIUI V5 and its going good..fast, responsive, smooth and decent battery of 18 hours avg..
@jsiv - i wanted to ask u a question.. which country u hail from ?? because the stock 2000 mah battery is not available in India, my region.

What exactly is battery calibration here? Please pardon my ignorance. I did a full charge when my phone hit got switched off the day after upgrading the OS. Is there something else I must be doing here?
I've had this problem right after the upgrade. So, I don't think it's an issue with my battery per se. It could just be JB.
How good is the Cynaogen Mod ROM in terms of battery life?
Or would it be wiser to switch to Android 4.0/ ICS?
I live in Denmark. I ordered it off Ebay, but I see now that the UK shop I got it from doesn't ship to India.
You searched Ebay for "Samsung genuine 2000 mAh battery" or similar?

Cyanogenmod roms are very fast ROM they are good as hell
Ur problem is genuine go to the playstore and download battery calibration app and follow the instructions in the app charge or battery up to 100 % and caliberate the battery u should have made an nandroid backup before upgrading

This has to be done every time you do a ROM upgrade or change ROMs.
CM has excellent battery life when compared to other ROMs.
If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.

As reported before, it seems that many official JB ROMS are not as optimized as other national versions and are battery hungry. It was suggested to upgrade to the French release (XEF).

I did this... and unfortunately, it did nothing in my case.
I went to the CM site, but I didn't find any stable build for SGS2. Is there a thread on this site I can refer to for the same?
Also, what's the best way to go about installing a different ROM? I have so many apps, sms messages, pics, mp3 files, 3gp files, etc. Sure I can take a back-up onto my SD card. But won't I lose all the apps once I flash the current Android installation and install a new ROM? Any article or video on YouTube that addresses these points? Please point me in the right direction. I practically don't use my phone even half as much as before and I'm having to charge it twice a day, as against once a day earlier.
Also, the rapid battery loss seems to be causing the phone to heat up a lot if I'm on a call longer than 15 minutes or having the screen on for 2-3 minutes straight.

There is no stable version of CM 10 on I9100 because of the some issues. You can flash one of the nightly builds.They might not be necessarily unstable.
No you wont be losing everything when you install a new ROM.You lose once you do a data wipe.It is suggested you wipe everything before you install a new ROM.
With a data wipe you'll lose the following - SMS,contacts,call logs,apps installed and respective data.
What you wont lose - Anything stored in the sdcard partition - Pictures, Videos, Music, Apk files and Anything stored on the Ext SD card.(unless you format them specifically)
Best solution is to use titanium backup app(You need root). This way you can backup your apps and resp. data,wipe data-install ROM,and restore the previous backup on the new ROM.

As far as the battery issue is concerned,do a clean ROM install through Odin.
