Phone: Galaxy S3 (international)
ROM: cm10.1-20130711-Experiental -i9300-MEMCPY
Kernel: 3.0.64-CM-gf79dbef
I had phone-freeze problems on stock ROM so installed CyanogenMod to see if the problem would be fixed.
Love the ROM but the problem persists and now the battery drains really fast. With very little use, by noon it is depleted. Some strange looking battery profiles attached for reference.
Would love to fix this, don't see exact problem described in other threads, any advice would be appreciated.
Cheers, Greg
Have you read the "Ultimate unusual freezing thread" in general? If not, that's your first stop.
Yes, I read that and ran the Dummy File Generator, ironically the phone freezes each time and cannot get through the cycle (16GB). I saw that Chrome and/or swiftkey might be the problem so I'll uninstalling these. I'm doubtful though as these both worked fine when I first got the phone.
Try using better battery stats to help detect if there's anything funny draining your battery, specially wakelocks.
I'd worry more about the freezing than high battery drain, which is fairly normal on CM.
If the freezing still happens on a fresh install of the latest stock rom then I'd suspect motherboard failure -warranty repair required.
Usually screen uses most of the battery but in your case its Android os , I suggest you try some kernels like siyaah or googy max and configure sTweaks to get better battery life

Its supposed to freeze. You're supposed to leave it and let it unfreeze itself. Could take an hour.
Try to shut down the MediaScanner, required rooted devices.

fixed - kind of
Status report: after an unsuccessful attempt to flash a new kernel I reverted to stock rom. phone-freeze and battery-drain problems are gone.
After trying android 4.2.x, I like it and want to get it back without the above problems. I've read that cyanogen mods are battery hungry, but is this also true for other roms on which they use cm as a basis, eg. paranoid android?
cheers for above comments.

Paranoid Android variants are hungrier than cm IMHO

Exactly the same
I exactly got the same here. My phone freezes sometimes on a Samsung based Rom. So I tried a lot of different CM and AOPK Roms and kernels.
On a Samsung Rom the battery is quite good (well not as good as others report but 2h Screen On are always achieved) but on all CM Roms I got a huge battery drain. Android OS is causing it. But by looking into BetterBatteryStates nothing is unusual. It looks like on a Samsung Rom.
Any help? WiFi, Bluetooth are always off. Sync: push: one email account, 2 accounts one an hour

Use GPS when needed . if u got stweaks , set as : UV -75mv . dual core mode + max_CPU = 1200 MHz should give decent battery life .

Well there are GPU tweaks as well which I'm not familiar with but people report better battery life. Personally I get through the day with above setting may it be aosp/sammy. BTW I suggest UV because it deals with avoiding heating it doesn't affect battery performance

Well actually the problem is that the battery behavior is just strange. On Samsung it's ok but the phone's freezing.
On CM it isn't freezing but the battery life is quite poor. The phone doesn't get hot, BBS is just normal. Who knows what causes this. I think a bad chip or what?

Bad chip , I don't want to scare you or anything but yes that's a possibility. Refer freezing threads they've got some info . personally I'd flash full stock firmware and test it a whole day before concluding anything

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.
After upgrading to ICS (via kies) the battery really sucks. Last for a whole day if im lucky. Is this normal??

From what I've heard, it's usually improved - BUT some power management bugs that affected stock Gingerbread kernels but were fixed in all custom kernels are still present in ICS, such as the good old fuel_alerted wakelock - so while it's better when working well, it's more prone to breaking.
I'm happy if my battery lasts for a day as i'm always messing with it(one of these days I might use it to make a phone call)! Have you tried putting it on charge at bedtime? I find that helps a lot.

I would try to avoid over-charging it, it's not good for any battery. Once it hits 100% (so long as it's correctly calibrated) unplug and use as normal.

same here i upgraded to ICS xxlpq and have been using it for 3 days, im struggling to get a day out of it ... its exactly the same setup as when i ran XEU (KI4) 2.3.4 unbranded UK. I noticed ram usage has increased as well as the amount of system processes. both times I rooted and removed bloatware. when my contract runs out in 6 months I will be looking at either a pure asop phone or an iphone 5, The galaxy s2 has a great screen but the batterylife if weak no matter what custom rom and custom kernal is running. Also I can get a wifi signal in my bedroom with my laptop and my old iphone 3gs but nothing with the s2.
Also please can anyone advise what the best pure and minimilistic asop rom will be for the galaxy s2 ive read cm9 mite be soon but is there anything thats great for battery life ? ...... thanks for you time in advance :=)

Upgrading to custom ICS roms is usually a great way to enhance your battery life, because they're always containing tweaks and optimizations!
This worked for me
Device: GT-I9100 (Samsung Galaxy S2 international)
Carrier: Smartone
Country / Language: Hong Kong
OS / Browser / build number (if applicable): ICS 4.0.3/IML74K.ZSLPE
I can confirm that I have resolved the battery drain issue after upgrading to ICS on my device. The problem was partial wake locks caused by the exchange service.
One of these measures fixed the problem for me (it might have been any of these, although I have a strong suspicion that the factory reset is the only relevant one):
- factory reset of phone; didn't restore the settings and accounts, but set them up manually
- wiped cache
- did not reinstall ADW launcher
Hope that helps.
The good news is that now the battery life is definitely better than it was on Gingerbread.

This isn't really true. Once it hits 100% it pretty much runs off the charger.
By depleting it all the time you are ruining the battery that way

Leaving your phone on charge longer than is absolutely necessary ie taking it off charge as soon as it gets to 100% will not affect your battery life and there is also no need to manually calibrate the battery. I installed DXLP7 and was getting poor battery life due to a wakelock, I found and dealt with the cause and immediately battery life improved. In my experience battery life on ICS is as good as it was in gingerbread. Better battery stats is your friend.

I had upgraded my sgs2 to ics yesterday. The new version is draining the battery very seriously. In the previous version, my sgs2 could last for about 12 hours from a fully charged state. But now the version can only last for 6 hours, which is really unacceptable.
Is deep sleep? You can check with CPU-Spy. If not, remove the battery a few minutes and then returned.

I had huge battery drain issues from exchange and email waking the device and constantly doing something. Removed the accounts and then set them up again. Like night and day now, better than gb. On LP7 and never wiped.
Cheers

Keep a look with BetterBatteryStats, and see if there are any apps messing up.
I have better batterylife with ICS by a margin.
And about leaving the charger on during night, these are kind of myths really, you can keep it on without any worries, and also charge it without being totally drained.
Most of these thoughts come from the old Ni-Cd times with memory effect.
I had removed the Exchange Account yesterday and the battery drain problem disappeared. The account was added back after about 10 hours. The battery usage is now back to normal (a little bit better than the situation before the ics upgarde). Thanks for your hint.
Cheers.
SG S2 ICS Battery drain issue
Had upgraded to ICS when it launched in India and literally went berserk due to the battery drain issue. Googled and googled, found a lot of things, tried most of them (except for changing ROMs).
Then, Voila, last 4 days - a complete twist to my sorry tale. I first disabled the phone backup option (to Google), did a factory reset, said No to most of the options that are asked on restart, and didnt install the earlier applications from the Play store en masse (earlier, had a number of games and other 'what I thought was useful' apps). Now, only have the basic apps plus Poweramp, Shazam and NQ Mobile added. And the result - the battery is back to normal. Phew....big relief as I use the phone pretty much for mails, music, phone.
I want yo add some thing very annoying, I discovered today after upgrading to Resurrection ROM.
In fact, even with the device connected to my car power supply and using Copilot for about 1 hour, the battery continued it's discharge instead of charging.
So what to say and what to do?
Cheers
I have been struggling with trying to figure out if the battery life I am seeing is what my Atrix is really capable of. I am occasionally a heavy user, but on weekends I am a very light user. I'll start at 8am with 100% and be almost dead at 6-8pm. I have searched around and seen other Atrix users with 24 hours of battery life and even if I tried my hardest to not use my phone I wouldn't get those kind of numbers. I feel fairly confident in saying i scoured search results and tried everything i could find to extend battery life.
Am I doing something wrong?
Is there something I can do to help?
I know it's been asked before, but I am hoping to get some current answers for this question: what kind of battery life numbers are you getting on your Atrix? Which rom are you using?
Atrix 4G running CM7 RC3. If the answer is "keep it charged as often as possible", it is what it is. It would be great to find an answer to why battery life is so much shorter than others though! Many thanks in advance.
Just noticed CM7.2 stable was released, upgrading to that now to see if battery life improves. Might try a full wipe to see if battery life is better without email, syncs, etc. etc. if the upgrade doesn't help.
i would recommend getting cpu spy and also download and install as a zip 'blue sleep fix' (blue sleep zip can be found in the CM7 thread). This has greatly improved my battery life.

Also, use ROM Manager or equivalent to stop all non essential apps from starting on boot.

You should turn wifi off when not in use, that will save battery life.
Badass battery will let you know how you spend your battery by % and let you know which app takes the most battery. (Lets you get a really readable easily understandable battery read out.)
I can help you get even better battery if you use this app and give me some numbers (it has a share via gmail/etc)

turning off wifi is not going to help him that much. I leave my wifi on all the time no problems, make 2 days light usage no problem.
More likely he's got some apps running around in the background. I suggest he pick through what he's got installed and start turning off the things that like to sync all the time in the background.
I think step number 1 would be to install a non-stock ROM and startover fresh.
Blur-based ROMs (Nottachtrix was really good) then the faux123 kernel then slowly start installing the apps he likes to use and monitor battery life. It might take a month but he's definitely got an offender here or there causing these problems.
also install Juice Defender. My mom's Galaxy S2 was having tons of problems with battery life even though she wasn't using it at all, 60% battery life at 3pm without using it at all, installed that and immediately helped her a lot, like 80% by 3pm WITH use.
Also, clear your dalvik cache. After installing lots of stuff and not using it, it just fills up with sometimes poorly written code. Clearing it always makes phone faster in my experience.

I think this is what I will do today! I'll do a nandroid backup, and try Nottachtrix with no extra stuff installed or setup. I will report back! I appreciate all the help to get my phone performing where it should be.
Just wanted to report in. I tried a clean ROM as stated in my previous post with no luck. I just couldn't get past the battery life I was getting with cyanogenmod WITH all of the apps and syncs enabled. Should I try another ROM maybe?
Maybe your battery is just a bit old? After ~2 years, you can expect that battery life drops dramatically. if you are a heavy user this might happen earlier. Maybe check with the battery of a friend of yours whether it's a software or a hardware issue
Nvmd
You could be right, the battery might be dying.
I was on vacation the past few days so I got the opportunity to not use my phone most of the day (job requires me to use the phone a lot). The battery lasted about 12 hours and looked like it had about 4 hours left. So maybe I am expecting too much, but I'm not trolling...no.
If you aren't going to be helpful, go somewhere else. You could have said "Your phone screen was on for probably longer periods than the average user and that's why you can't hit longer hours". Based on your previous comments, I shouldn't expect much from you though.
Many thanks to all who are helping me. You're all awesome.

11-12 hours.
I also have 11-12 hours with 1 charge. And it is not enough for me. I use only Whatsapp ( a lot usage ), a little bit browsing, 20-30 minutes phone calls. These are all. And 11-12 hours is sooo bad for them i guess.
I have an "suspend linux process" drainage issue. Maybe because of it, I'm getting this result.
How can I extend my battery life. PLEASE Help!
I love S2 for every feature in it
But thats my 3rd mobile which is causing Android Os High Battery Usage problem and there is still no cause i find yet
tomorrow i bought a used s2 of o2 carrier which was unlocked for my country everything was fine i check that in market android os and system was on 2 %
but i just did factory reset for deleting data which was of old owner
and BOOOM here comes the android os high usage problem again
now i am trying everything like factory reset,firmware changing but still no chance and its draining battery its my 3rd mobile which cause my same problem and 3 of them was s2
i also try to find one click gremlin remover for s2 but its not available because that thing was my last hope please tell me what to do

The android os high battery usage could not be a problem though.. I think that if you keep your screen on for sometime, the screen on time will go to the first place.. and I suggest you to try ParanoidAndroid Jelly Bean

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 would suggest to do a factory reset once more and check without installing any app the battery life
TouchWiz gives high battery drain compared to custom ROM's, probably due to the bloatware.
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

Hi everyone!
Some days ago I bought a new battery for my S3 (seller said to be genuine) and I am disappointed because its performance is almost the same as the one I was experiencing with my old battery (18 month-old battery). For this reason, I have been researching and I have done this until now:
*) Being honest, this comparison is somehow subjective since apart from the battery change, my S3 was officially updated from 4.1 to 4.3 almost at the same time I changed the battery. Then, I wonder whether this update may have affected my diagnosis on the battery duration.
1) According to the point * I decided to do a battery calibration "without root" consisting in draining the battery to 0% and charging until 100%. I haven't seen any improvement doing this.
2) As consequence I analyzed wakelocks. I have addressed two of them from the System:
- AudioOutLock. to fix this one I did as recommended: disabling sounds when typing and all of this.
- Backup. Fixed by disabling the backup from Google (I would like to have it enabled but if it is causing a battery drain...)
3) I let the phone the whole night turned on with the 3g connection on and I got a ratio of 2%/hour draining. I have read this is more or less under the normal parameters.
After doing all of this I'm still not happy with the performance. Usually, my mobile gets under 20% by the end of the day with the screen on in a range between 1h30m and 2h. If I remember well at the very begging (when I bought my phone), I was getting my phone at 20% by the end of the day but having the screen on for 4h or more. After buying a new battery, I was expecting to return to that situation.
Do you have any hint? As for example a better way to calibrate? Factory reset may help? Should I check a specific wakelock?
Thank you very much in advance!
I forgot to mention that when I let it charging over night, my s3 does not always charge until 100. Sometimes it's until 98 or 95. I don't know if this helps you guys as a hint but I want to provide as much information as possible.
Thanks

Thanks!, I will check. But so far I have briefly seen it looks like there is not a specific solution more than disabling gNow and some other things. Maybe a good option is to downgrade or using a custom rom in which there aren't these problem.
its same to me.
aftet update 4.2 to 4.3.

Hi, look for XDA-forum "Better Battery Stats", there is an excellent tool to analyse battery drain and the community in this thread provides very good support.

Thanks!. I have been using Wakelock detector but I will try with this one. I was wondering if using this kind of applications for checking the wakelocks may provoke some battery drain itself. I mean, should it be used just for analyzing when you experience a battery issue? or should they be permanently installed no matter whether you have battery problems or not?

Hi, Better Battery Stats is using an already existing process of Android to obtain it's information, therefore the influence of the app itself on battery drain should be negligable.

Thanks for the info!. I have not seen anything special in the partial wakelocks. In the kernel wakelocks, it is difficult to distinguish whether one entry is specially problematic or not. After what I have read so far it may be the mix of social apps I have now installed:
- Whatsapp
- Twitter
- Messenger (FB messenger)
- Line
I guess maybe I have too many of them reason why the battery is draining more than normally when the screen is off

Which firmware you are using. .Sometimes it's the problem with the firmware. .For example GML2 and ML4 version firmware has a pretty bad battery drain. ..

mk6 is fine with the battery...so firstly install an app called better battery stats search for it...install it and let the phone to be in standby mode for 4-5 hours..and then see in partial wakelocks and kernel wakelocks..and post those screenshots on bbs thread...someone will surely help you..
sometimes changing kernel could solve the problem..boeffla is the one i am satisfied with..and agni kernel is also one of the better kernels..:good:

Sorry for the delay to answer, I've been busy. Here I post the images of the battery stats. Sorry, they are not what you told me to be having them 5 hours quiet (that's difficult for me). However I can tell you that the 40minutes of screen on where just chatting on whatsapp or checking emails; no angry birds or need for speeds hehe... Are these images ok to be posted on the thread you told me? Thanks in advance!
I had a poor battery perfomance after upgrading from 4.1.2 to 4.3 until I've disabled fast dormancy. It seems that in v4.3 is enabled, and if your carrier doesn't support it, it will eat your battery. Donwload free from market "fast dormancy togle" by Siyah, and that's it

I have just rooted the phone and disable the fd. I hope this works!. Thank you very much for the info. However, now that I have it rooted, do you suggest to install a custom rom for getting a better performance? if so, which? there is a good one with 4.4 and multi-view?.
Thanks in advance!
Try flashing allblacksback mod it makes the whole system dark and saves battery on display and also I recommend disabling Google play services but this means there will be no push services but it saves a lot of ? ? ? ?

After giving a try to the idea of disconnecting the fast dormancy here I give you some reports on the battery consumption. I don't know why but statistics are wrong from the point of view of the duration (3 days).. since I disconnected it just 10 hours ago. I think its consumption is still huge. I hope you can give me a hint on it. Thanks!
Ive installed smartdroid. Battery perfomance seems quite better now! What do you think from the screens? However.. i find the screen too much consuming.... ive seen people managing 5 hours of screen in a day. Why i am not? May it be battery or configuration?
Thanks!
Do you have any hint on this? Ive seen that with the screen off the consumption is really good. However, with the screen on a doing normal stuff: chroming, feedlying or whatsapping it goes to a 20-25%/h.
