[Q] Battery Drain - Galaxy S III Q&A, Help & Troubleshooting

Hi,
I would like to ask for some help regarding battery drain. Im currently using S3 with CM10.1 and the battery drain is quite high.
Using BBS, i have gathered some stats and i would like to request for some help in analysing it.
I see that multipdp is taking up a huge chunk of the kernel wakelock. my signal strength is at -85 mostly.
In the battery stats, it also shows that android OS is taking more than 50% of battery, that's unusual right?
Any advice would be greatly appreciated!

Hi,
Any help please?
Really need help! Appreciated thanks!

all the cm roms have the problem of battery drain. i get around 15 hours on a normal usage and around 10 hours with a little bit more usage. try changing the kernels.
:good:

Cyanogen mod roms are known to drain battery much faster than touchwiz.so you cant really expect the battery life to be the same as on stock or stock based roms. you may improve the battery life by using an app called Greenify. it hibernates apps so that they will not run in the backround. this can help considerably. also make sure to turn off gps , bluetooth, wifi. and mobile data when not in use. also battery should improve after three charging cycles

Do not bump before 24 hours of inactivity on the thread. It is against the rules that you agreed upon when signing up for this forum.
CM doesn't have the best battery life, I see some Facebook related things. Facebook is a known battery drainer. Their app coding is atrocious.

Thanks for all the feedback. I accept that CM can drain more battery than stock.
What im quite bemused by is from seeing how other people's battery usage do not have the OS taking more than 50% but mine in fact does.
I just have a feeling that's unusual?
Sorry for not abiding by the rules, my anxiousness to find a solution :crying:

Just read the ten million identical help battery drain posts for clues .

Standby current and identifying problem processes.

Those of you using a battery app, what is your usual standby battery drain? I have been having some issues lately trying identify what's killing my battery on standby. I get pretty decent battery life using the device, but it seems to drain quickly on standby.
I am seeing 100ma+ with Wifi on, after turning all radios off and rebooting I can get it down to ~20ma or lower. It seems in the battery usage screen in settings that "Android OS" is using a lot of the battery, but it's hard to tell what actual service or process it is. Is there anyway to pinpoint the exact service or process munching the battery?
Thanks.
I'm no expert on this app, but Betterbatterystats might give you some useful information.

Thanks! That actually helped me narrow it down, it seems to be the "locationfriendservice" part of google maps, and a quick search indicated that this is a big problem for lots of folks.
It's possible I just had noticed it before when I was all stock, so I was thinking it was a result of a new kernel or something.
I have done what I can to mitigate the battery-hungry maps processes and will see tonight if I can retain better battery life (was losing like 10%+ in 6 hours on standby!).

[Q] Battery drain problem - or is it just me?

Hi there,
just in advance: Yes, I have read quite a bunch of battery drain threads, but non of them seemed to help me.
Compared to GB, my SGS2 doesn't even seem to last more than a day in terms of battery life.
Now I wonder - is it just me playing around with (otherwise awesome) CM9 and battery life is actually normal or is there some kind of battery drain going on?
Running CM9 14-04, stock kernel, LPS baseband.
Attached please find BBS stats and other battery stats screenshots.
Help very much appreciated

Awake over 2 hours, 1 hr 43 min screen on, down to 62%. That's on track for 5.5 hours awake time, and about 4.5 hours screen on time. Looks pretty normal.
You MIGHT be able to squeeze a bit more juice out by playing with your sync and display settings, but that otherwise doesn't look that bad.

Sync is pretty much off completely and display brightness was on 'auto'...
the graph looks pretty good without gsf and alarm manager wakelocks
Have you tried to re-calibrate your phone? I once messed around with my battery and i lost 70% battery overnight when it was on 100% because i was unplpugging, plugging my phone in randomly.
How do I do that?
Just bought a 2000mA battery and it seems I still got the same 'issue'...

Download battery calibration app from play store, put phone on charge, wait untill will be 100% charged, open battery calibration app, click calibrate, unplug you phone. Done.

Did you try to wipe your battery stats? Also, I noticed that playing around flashing the Roms, requires 2-3 full charging cycles before the battery was "stable" again
I've also read the following but didn't try it (I imagine it does the same than wiping the battery stats in the recovery, but you never know, you can try it):
Delete batterystats.bin in data/system, after full charging (with Rootexplorer or another app)
Then, use it until to 90%, and full charging.
Good luck!
When is it a good idea to wipe battery stats? When it's empty or at full charge?

The CM9 has some battery drain problems because is still developing maybe try wiyth another rom and see if the problem remains

Stats seem fine to me. Your phone shouldn't drain much when idle, but once that big screen is lit up the power drains much faster. The SGS2 stock battery is not huge to begin with either. Your 2000mah will be better though, especially after using it for a few cycles. You can also try flashing a different stock kernel or custom kernel (Siyah, etc).

Thanks guys!
So charged my 2000mA battery up to 100% now and wiped the battery stats. Hope this helps.
I really wanted to stick to CM9, because I don't wanna do a factory reset every couple of days when flashing other ROMs, because I'm tired of setting up all my stuff over and over again...
Are the other ROMs really that much better? Thought that CM9 would be best, because most popular...
Or could it be the baseband/modem too?
I am on LPS right now... I've searched the forums forever, but can't seem to find an answer for:
What is the best baseband/modem for battery life?

[Q] Need assistance for battery drain

Hey guys, I've been having some battery life issues with my SGS II for quite awhile now and decided to seek help now as I can't quite take charging twice a day anymore. I've uploaded the BBS as well as screen shot of the battery usage for a full drain (part 1), as well as an overnight drain (part 2). I appreciate any help given in deciphering what is the cause of the drain.
My current ROM is Slim v2.9.0 using CM10 Kernel.
Let me know if there's any more information needed, thanks in advance!
You don't have any serious battery drainer.. Have you thought about getting a second battery though?

I've tried changing batteries with my brother's phone (1 day charge rate with heavy usage) and still achieved pretty much the same battery life when on my phone.
I've noticed that I have this problem with AOSP/AOKP roms. While I'm on some Samsung based custom, battery is excellent. All with same kernels!
Maybe you should try flash something like Neatrom as Second rom and see how long the battery lasts.
Sent from my GT-I9100
thanks for the advice, I'll give that a try!
I fully agree with kilometers4 (post #2), looks like poor battery capacity. However, as you already changed the battery without significant effect, it must be something else.
Looking at the logs you provided I would run the exact same "tests" but with the data connection disabled. These results could help in further debugging.

[Q] Need expert help in analyzing my battery consumption

Hi Everyone,
I know there are thousands of threads regarding battery consumption on the SGII - I have tried many many suggestions and I still have terrible battery life. I was hoping someone could give me a hand in analyzing if my stats are normal or if there is anything I could do to make it last longer - my battery life is just terrible.
I'm running RootBox 3.2 Jelly Bean.
Please find attached my BBS and Battery graphic. Let me know if there is any other detail that I can attach in order to troubleshoot my battery consumption.
Thanks a lot in advance!
Try using 2G networks when you don't need big bandwith. 2G is enough for WhatsApp, WAP sites, messengers.

I have tried being on 2G the whole day with very similar results
Disable all data connections for a while and compare how much battery was used.
Try GetRIL to get a match baseband and see if it improve it.

Your log is not looking that bad considering your screen on time of about 2 hours and the CPU usage.
The cause of the largest wakelocks seem to be your music player and synchronization software. Maybe you could get less wakelocks by reconfiguring them.

So you are saying 2 hours of screen on time draining over 70% of my battery is decent? Not sure how much its supposed to give

No, this is not what I'm saying.
First the battery draining is not over 70%, it is 64% (according to what your BBS log says). Second, the amount of time the phone spends running with a 'high' CPU frequency is quite large, or, in other words, the amount of time your phone runs at 'low' CPU frequencies or even better, is in deep sleep, is quite small.
Taking all this together I think you do not have abnormal or excessive battery draining.

How good is my battery?

This is my battery stats for today's use. How is it? Thanks.

In order to get an accurate response, you'd need to post more screenshots from BBS - things like wakelocks, kernel wakelocks and app activity will help greatly to diagnose your phones battery consumption.
By the looks of the 1 screenshot that you have provided, I can only assume that you are a pretty heavy user...as the device did not have much deep sleep time (only 25%) and the battery per hour rate is 7.2% .

Yes I use my phone a lot during the day. Next time I will do a 100% to 1% and post more shots.
I updated my op with more information. How is it now?

BBS Review
Here is my dump. How is my usage? Is 12.5 hrs till 4 percent good or bad? Note that the awake time is higher because I was listening to music with the screen off. Don't refer me to the BBS thread because my idle battery life is great. Thanks again!

You need to actually read the BBS thread..
If your idle battery life is "great" then it boils down to how you are using your phone. Are you letting it sleep or are you using it a lot?
Getting rid of GoChat will improve your battery life as it is creating a wakelock.
You will gain still more battery life by going into Settings->Sound and unchecking all the boxes towards the bottom. This is yet another known issue..
Looks like you are using it a lot, and getting the battery life associated with a heavy user.
Do you have a more specific question? I'm not sure what you are looking for here really. The main thing you need to do is research this stuff so that you are familiar with it.

I read the BBS thread and have already posted an idle log there. I only posted a log instead of a screenshot cuz I was lazy and didn't feel like taking 5 screenshots. The time that the wakelock was on was the amount of time I used GoChat, meaning the screen was on as long as I was using it. I just wanted a yay or nay of my battery life. I usually play videos from youtube for a solid hour, browse the web intensively, take a couple of photos, use 3g, and send some texts, if that helps in putting a figure on my battery usage from the screen on time vs the deep sleep time, so thanks for answering my question.
