Hi guys. My SIII's battery life is horrible. How can I have a good battery life ?
You can always do the obvious things like turn off mobile data, wifi, sync when not needed and you could also turn brightness down to reduce screen power usage,
The other option you have is to flash a new kernel such as siyah kernal, which you can underclock your cpu and gpu to prevent battery drain.

Better Battery Stats and check for wakelocks first.

Thanks I will do these settings. What about batterie ? Do you guys suggest a good battery ? Or Should we wait more to get good batteries ?

It was truly helpful, thank you for the tip.
betterbatterystats indeed, however I'm having some issues with the support permissions on jb.
Also check the battery life post in the general forum for some tips

I think screen brightness is the biggest drainer.

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?

I have updated my S2 with the official ICS. My battery life is now so poor I struggle to get a full day's use. Before the update I would get about two days with moderate use. I have read that the battery life should improve with ICS update. Can anyone explain this and give a solution as it is very frustrating.

try some batt monitoring apps from market and see whats draining ur batt and resolve the same either by force stopping those apps r deleting them if u find they r batt drainers
and also for ICS it requires at least one r 2 recharge cycles for things 2 settle down

I am using a battery monitoring app and have closed apps that use most battery. I have also switched off wifi, sync, gps which I never used to do, but still no real improvement.

Samsung Official ics will always be a battery eater.
Suggest you to root your phone and install a custom rom like wanam/slim etc. These will remove all unnecessary bloat wares giving u better battery and performance. (Do remember to read all the necessary info before u root).

ics generally uses more battery than gingerbread
i remember getting 3 days easy on moderate use on cm7
still you can try custom roms because they give better battery life

Have you tried BadAss Battery Monitor?
imho: too many running services in background.. try to kill/freeze unnecessary apps(use link2sd), but most important thing is it seems that current ics is not optimally written/optimized, most kernel can help minimize this effect (but minimal e.g. speedmod)... if you can bare with this condition you ics is for you.. but if you are expecting an optimal performance of your sgs2, you should consider reverting back to gb ..
If you wish to remain on Stock Rom, please root your phone. CF-Root kernel here
http://forum.xda-developers.com/showthread.php?t=1103399
Then use Titanium Back to freeze unwanted apps which drains your battery. List of applications safe to remove here.

Use BetterBatteryStats und search for the kernel wakelocks.
And use CPU Spy. How much is the amount of deepsleep?

According to CPU spy deepsleep is at 42%.
According to badass battery the battery is consumed as followes: 60% kernel and rest of apps about 9% with none more than 1.5%. Balance is consumed by screen 15%, phone radios 3%, phone 13%

Deepsleep with 42% is far to little
Find out, with process drains your battery.
Use BetterBatteryStats und look for kernel wakelocks after display is 1 or 2 hours off.
I had the same problem a while back and battery would go down to 20% in about 5 hours. Did a factory reset because when I upgraded, I didn't wipe cache. I read somewhere that old gb code could cause issues.
After the reset, phone works great. I get to 50% battery in about 13 hours. If you can, give it a shot. Of course, back up paps with Ti, otherwise reinstalling them is a *****. :banghead:

I'm quite satisfied, after first cycles now with stock Italian LPF and Phenomenal 5.4 Medium Kernel I have very satisfing results (I forgotten the phone on this night, in 5 hours it drained at least 1-2% of battery).
In normal operativity I'm on 13-16 hours with 1650mhA battrey.
Thanks will do that and post results for further help.
Battery life has now improved to about 15hrs since taking the battery out for recalibration and putting it through a few charge cycles. But this still feels to low.
Ps deepsleep still at 42%.

oooor you can downgrade to Gingerbread and get a custom rom/theme for that awesome ICS feel and at the same time get awesome battery life
I backed up my data, did a factory reset, restored my backup, charged the battery and now the estimated battery (@ 64%) is about 30 hours. So it seems my battery problem is sorted. Holding thumbs!
Sent from my GT-P7300 using XDA
I suggest i apply all the Tweaks as possible first, secondly install a cok kernel like Siyah, then see if there's any difference
Imo, i bet ICS is eating more battery than Gb, so dont expect a better battery life, try to.enjoy the new feature instead

Hi folks I'm on cm10 and I think something drains my battery but I have no idea how to figure it out also when I go to system settings > battery it tell me I have 30m on battery when my battery is almost full I attached a pic
I downloaded better battery status but I have no idea what I'm reading lol...
Any suggestions would be nice thanks.

your phone doesn't seem to sleep, did you flash the bluesleep fix from epinter?
if you want to know more about what's eating your battery you can install better battery stats, it will show you if you cpu is sleeping and what processes are keeping your phone from sleeping.

How long does your battery last on average?
I suppose these numbers seem pretty normal depending on your usage.
Maybe clear battery stats in cwm or with a battery calibration app..
Try calibration

Or You can just wipe your batterystats in advanced options of CWM

lol guys this is fine ? the battery doesn't have any drain. look at the part of the "screen on" if u use u phone it goes down and on the "screen off" it hardly drops on the diagram.
U don't have drain is more Diagramm drop. I think u just think something drains but it's totally fine.
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,

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.
Sent from my GT-I9300 using XDA Premium 4 mobile app
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 .

It depends on what you have been doing and what's your screen on time... If you have been gaming... Then it's OK..
Plus install better battery stats and let it run for 4 5 hours on standby and see and see what is draining your battery...
Sent from my GT-I9300
Your battery stats looks oke since you have used 30% percent in 6 hours.
Android OS + Android system usually use 20% together, which is now 10%. However, your screen usage is high, related to reading articles or watching videos.
Just reset your battery stats via recovery and your problem will be solved.

False information as resetting battery stats will not recalibrate your battery nor make battery last longer . Please read the stickied faqs and guides .
Plus most recovery s have no method of wiping battery stats as its a pointless exercise .
Thanks to all but. Will follow all what have said thanks!!

It depends on the kernel and it's profiles/governors too. After installing Boeffla I got much more from my battery.You can choose if you want better performance but much more battery drain, normal or less performance and less battery drain. After looking at your screenshot, I'd say it's ok.
