[Q] SGII CM9 Battery Problem - Galaxy S II Q&A, Help & Troubleshooting

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?

It isn't ICS, i flashed it on a friends GSII at the same time and his last 1-2 days like usual.

i´m test ics roms, and have much differences between them.-
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.

Yes, gmail, facebook, etc... Remember that I said screen off, obviously screen on drain is considerably higher.

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.

There is a free version of better battery stats on xda in the android section, just look for it. But, do consider supporting the dev, BBS is a great app.

It's always better for everybody to support the developer by purchasing it on the Play Store, I did it.
It's a thing of principles, if you support developers they will keep improving apps and making our lives more enjoyable with our beloved SG2.

[Q] "Suspend" + "Events/0" Processes Draining Battery?

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.

New user - surprised at poor battery life - help?

I'm a new Galaxy S II (and new Android) user, and am a bit disappointed in the battery life of my new phone. It was running down extremely quickly yesterday, only lasting about 12 hours with relatively normal use (sending half a dozen texts, downloading 2 apps, checking Facebook and Twitter once an hour or so for a couple of minutes throughout the day). I allowed the phone to discharge completely and charged it fully last night, but this morning nothing seems to have improved. I burned up 10% of the battery in half an hour sending 2 texts, checking my emails, Facebook and Twitter and downloading and trying out a couple of apps.
I'm anxious to know if there's a bit of a burn-in time with the battery on this thing - does it get better after a few charges? I see a lot of people saying they can have the phone on for a few days in some cases, but that's definitely not my experience thus far.
I've installed JuiceDefender (balanced profile), AutoKiller Memory and Advanced Task Killer to try to sort things out but none of them seem to having too much effect and to be quite honest I'd rather not have to compromise my experience by running a number of apps like this to try to extend my battery life at all (nor do I want to have to turn the brightness right down to an unusable level, or set black wallpapers for example).
Does anyone have any real advice on this? I'm starting to think that switching ROMs might be worthwhile? I see that the leaked 2.3.4 ROM seems to have better battery life - is this correct? I'm a bit reluctant to switch to any other unofficial ROMs as there are so many I wouldn't know where to start. It seems they all make a lot of changes but I'd want to keep as close to the stock feel as possible, just with better battery life.
no one uses stock roms/kernels nowadays. u should flash a custom rom or kernel since they provided optimizations to batt life.

It is argued that task killers and memory killers will only make the problem worse. Juice Defender might be useful if you are using it for scheduling sync and turning WI-FI off when the screen is off, but this feature is only present in the Ultimate edition and you can turn off sync and WI-FI manually if you want. Also beware of rogue apps which are syncing all the time. It is normally the main reason of poor battery life.
Other reason, is that whereas powerful tech specs for phones were rapidly developed, battery technology didn't followed the pace. Our simply batteries cannot cope with our beasts.
Also, there is a thing that it's called "new phone battery blues" which is described as poor battery life due to excessive use of a new powerful toy. After you use your phone normally, for the purposes that normally people use a phone, your battery life will became better.
That said, personally I have a spare battery and a spare charger, and when the battery being used is low, I replace it with the charged one. Sometimes it is necessary, sometimes not.

They also have a tendency to look very tacky I think though. I think Samsung's skin and widgets are pretty nice and don't care too much for the mods I see in the screens of most ROMs. I'm really looking for something very similar to stock, except with better battery life if there are any suggestions? That's why I was thinking of just jumping to the leaked 2.3.4 if it had any noticeable impact on battery life...
Try using better battery stats, link in my sig, to see if you have any wakelocks, the thread has a good howto on using it.
The biggest thing that uses the battery on this phone is the screen, you will get between 4 and 6 hours of screen on time depending on usage and screen brightness.

Fair point - not all of the roms are everyone's cup of tea. My advice, as a starting point is to flash the stock XXKH3 variant for your area, and then flash a custom kernel, such as Ninphetamine's or Hardcore's Speedmod. This will greatly help with battery life, and also give you the ability (via root access) to use Titanium Backup to freeze apps and services you're not using, which is often the major cause of battery drain through 'wakelocks'; apps that prevent your phone from entering Deep Sleep, or continuously wake it up.
Update to the latest version in your area, uninstall those task killers and whatnot or do a factory reset, install the apps that you are going to use normally like facebook twitter and install better battery stats, decrease brightness to your most tolerable level.
use the phone normally and when the battery is low, use the tool provided in android to check if your phone is sleeping when the screen is OFF, if you are having wakelocks, then use better battery stats to find which apps are causing the wake locks.
No need to install battery management apps, or task killers or memory optimization apps (or as custom rom as yet), that would only compound you problem which may be a very small one to begin with
Thanks for the help so far guys. I've installed XXKH3 and flashed hardcore's Speedmod kernel, and am just getting things set back up the way I like them again. I'm going to uninstall the battery saving apps for now and see how the battery lasts the next couple days.
I'll install Better Battery Stats and keep an eye on any wakelocks too.
Thanks for pointing me in the right direction - it was all very simple and quick to get set up; the sheer number of kernels, ROMs, etc. is all a little overwhelming to me right now, being new to Android!

there are other tweaks with custom roms that aren't found in the stock rom (which provides better functionality).

wow, good for you
I used HTC Desire before this device, and the roms on there actually hindered battery life, even with all the fancy underclocking, so I am betting, without even attempting to brick my phone, that they are just as overhyped on this phone too.
I get two to three days out of my phone, using it as a PHONE. I can send and receive emails and texts all day, along with phone calls and the occasional browsing and still get at least two days before it dies. I turn off data when I dont want it and stick it in 2G mode and it dares me to kill the battery.
Just let usage settle down and it's fine

Q:I'll do anything if you can help with my battery life

ok so i am on ginger 2.3.3 with a day one x10a baceband 71 rooted with Custom boot loader so i can literally do anything except gain more battery life. i have tried ATK in the past and ditched it for Battery doctor cause i found when you charge with battery doctor i get about 6 more hours out of my phone. ad that to my 1800mAh battery from mugen power and i'm getting about 12 more hours then i did when i got the dang thing. killing tasks all the time deferentially helps. all in all i get about 24 hours...
what i'd really like is a custom rom that is Ginger that's whole point is battery life... i'd really like to forget to plug my phone in and not panic in the morning cause i'm at 10%
i have looked though allot of roms but can't seem to find anything with all the battery eating junk ripped out it seems most of them are putting more junk in
Are there any good LITE roms out there?
Define anything.
Try ThGo2 v7.0
Best ROM in terms of battery.Using it.I charged my phone fully and slept (11PM-9AM). Received 5 SMS and 3 Missed calls,but battery still at 100%.

try team rom it has decent battery life and is very fast and responsive
Sound to me more like it your habit rather than ROM/Hardware .
I wound't begin the debate here about ATK, but since your post doesn't provide any technical info. Let's try this..
> Seriously, stop using ATK.. it would just HIDE the real problems.
> Remove all unnecessary widget... clock, time, weather, photo, blah blah
> Wait for a few hour, is it significantly better?
> Remove some background-apps; viber, whatsapp, skype, trillion, imo, msg, brb, blah, blah, blah
> Wait for a few hour, is it better?
Well, it should... (definately )
Some geeks down here... skip it if you're lazy.
Actually, you will need to understand something that it's not really about ROM.
Most custom ROM provide you some 'minfree' tweak. Let's make it simple.
Case 1, minfree is 60MB (most custom ROMs)
> droid will just fill the memory with lots of apps till RAM is 60MB.
> droid will start killing the task aggressively when RAM is below 60MB.
Case 2, same thing with 30MB (Stock ROM)
> droid will just fill the memory with lots of apps till RAM is 30MB.
> droid will start killing the task aggressively when RAM is below 30MB.
So, using ATK means....you shot everything to pieces, and droid just recovers it back..
or.............................you and droid trying to shot everything down.....
doesn't sound useful.. does it?
ATK is then.. useless.. unless there are some legacy no brainer app eating CPU and tell droid that 'I'm busy doing my (stupid) job, go away and don't kill me'.
Alright, that's NOT the point about ATK.
My point is, if you having too much apps, beyond 'minfree' level, there is no way you can save the battery whether using ATK or droid itself.... ATK just hide it, and make it worse.
This is why most people get a decent battery life with stock, since it provides lowest minfree level (around simple 30MB), with a cost of system performance, which is one of the reason that stock one is the slowest one.
So, what you need to do is to adjust number of your running apps, close to the minfree level.
Or adjust the minfree level (autokiller memory optimizer?) to match your current usage.
So, all in all, if you're using custom ROMs, stop using ATK, uninstall any stupid apps till free memory is running around 60-80MB. This will give you 'optimal' (not best) battery life.
384MB is not decent enough for X10 to become a multitasking speedy beauty with decent battery life.

Try installing JuceDefender from the market. If after trying it for awhile you find an extreme difference in battery life then your problem is probably with one of your apps accessing Wifi / Wireless data all the time.
Another thing that could be causing it is if you're in a very low signal area. Where I used to work, I was lucky to get 12 hours out of my phone. Right now, it's been off the charger for 11.5 hrs and I'm down to 82%. In this case shutting of wifi and wireless data will help.
Sorry I can't offer any more suggestions. Good luck man.
I use battery Dr. for killing tasks as it helps by doing calibration charges when you charge your phone from under 20%. So I get more battery life than I did with juice defender
Also I get full bars on an hsps network at both home and work

I agree, I use JiuceDefender and if you take the time to set all the profiles it will help alot. Service area signal is also a key to battery life. Also try Battery Calibration App from the market, it will reset your battery stats. Make sure and leave the app open untill battery charges to 100%. Then let battery go till phone shuts down and charge again to 100%, That has been the best fix for me, plus Wolfberak's 2.3 rom's.
Ya using wolf note and I'm liking it.it's giving me my 3 days so I'm good.... I'd like to point out that juice defender as a few cool features but battery doctor seems to work better it has full cycle charging built in as well

[Q] Reasonable expectation of battery life?

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.

Which kernel? Flash Faux 1.0GHz and undervolt across the board by -50mv. Instant battery life!
Also, use ROM Manager or equivalent to stop all non essential apps from starting on boot.

Test your settings for a few days. If the phone stays stable THEN you set at boot.
Big thanks to everyone! Battery life has improved a ton (see picts)! It was hard finding the blue sleep fix, here it is for others to easily find: http://forum.xda-developers.com/showpost.php?p=25437046&postcount=436

Err, that is not good battery life at all bro. I can tell you barely used the phone. Atrix should be able to provide up to 2 days standby time...
I wouldn't undervolt either, I read on these forums that the battery gained from undervolting barely makes a difference

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!

JB battery life

Don't want to add to Omega ROM's 2000+ page thread.
I've been running the last few Omega JB ROMs and they're very decent speed-wise, however my battery life has basically gone to hell compared to the ICS ROMs. Are all JB ROMs like this? Can you suggest a different JB ROM?
And before anyone makes suggestions, thank you, but I have already done all the usual checking to make sure it's not my apps causing the problem.

Media scanner goes crazy keeping the device busy, like... at full 1,4GHz speed for long periods of time, some people reported about an hour of this behavior.
The easy way around is disabling it with Rescan Media Root
You can identify this issue using BBS, look for partial wakelocks.

Don't think I'm suffering from that. Since boot 10h 41m ago my biggest partial wakelock is Google Maps NetworkLocationLocator 25m 50s, 4% of my battery. Thanks for suggestion, hadn't heard of that issue.

The Google maps thing is related to Google now I'm pretty sure, it adds a bit of drain but imho worth it for the usefulness of it, downloading bus timetables is a thing of the past now

No JB rom, be it AOSP-based like Cyanogenmod or Samsung-created, are out of dev-preview/beta so give it some time to mature and get better.
ICS battery life has greatly improved from the first ROM, you cannot expect Jelly bean to be at that point just yet.

So basically they're all pretty bad on battery life then? That's fine, all I needed to know - I'll not waste my time flashing loads of different ROMs, and just stick with Omega for now

Omega was horrible for my battery, then I switched to wanamlite.
In the meanwhile i cleared my user data and performed a heavy cleaning of the rom by means of ROMCleaner and removing even more stuff than mentioned in the ROMCleaner thread.
Therefore I cannot guarantee whether it is a problem in omega's rom or in my data.
After a night the results were satisfactory, as shown in the screenshot. Soon I will start a thread to explain my approach.
Maybe I'll give Wanamlite a try then...
Hi Guys,
You might wana use the Better Battery Stats XDA version. you will see what's eating your battery.

On my phone battery life went down from 20+ hours on stdby to 8 hours on stdby with JB update!
I'll go back to ICS.
