hello fine people of XDA i'm having a few problems with the CM10.1 nightleys with battery drain. one of my friends has flashed this ROM and he says the battery life is great but i flashed and i went from 100% to 70% in 10 mins when plugged into the mains.i am using the anker 1900Mah battery and i'm wondering if it is the battery thanks in advanced

Use better battery stats to check the wakelocks and cpu spy to see if your device is deep sleeping and if you just flashed it give it at least 3 battery cycles before you judge the battery life..

Same experience. My battery can't even last a full day on just standby, with default gapps installed. Tried with both anker and stock batts. Think i will switch back to cm10 for now until a usable siyah kernel is released for 10.1.

thanks for the advice i shal give it a go (since 3 battery cycles should pass very quickly)
hi
very quick update the 27/12/12 nightly update is much better battery life wise :victory:
hi
i have taken all the advice and it is all going well battery life is not as good as my old CM9 stable rom i get through the day with about 80 odd percent (i don't have a constant data connection and my phone is basically just for music and talking to friends) but the more recent nightlys are much better for battery thank's to all who commented and i love the rom
battery drain on restart
Hello all
I am using 4.2.1 cm10.1 nightly updates... Today two times i'd restarted the phone battery drained nearly 20-30%. This is ubnormal right?
Later i did downloaded new version and also restarted the phone to check the issue again it ddropped about 30%
I do not know if it is a hardware problem? Battery ?
I ll try to attach screen shot
Thanks in advance
When I was on GB my bat with wifi was awesome. Since ICS wifi eats my device like a mutha.

Hey guys,
I have been running unnamed rom lately, but on any other rom including stock. My battery lasts for like 8 hours with little use and 4 hours with moderate use. When I see what is draining my battery it looks normal as the display uses the most, but I only have it at 30% brightness most of the time I have insurance should I see if I can get a new battery? Or any other tips?
Can you post a pic of your battery usage?
Have you tried to calibrate the battery yet?

Many things could cause battery drainage, such as oc-ing. You could find the original Samsung battery on eBay for a cheap price. Before buying one, try doing the following:
Clear OC/UV settings (i.e. put to defaults)
Download Battery Calibration by NeMa (on the Play Market)
Charge your phone and wait until it reaches 100%*
Tap on "Battery Calibration" and done
Once calibrated, use your phone as you normally would until the battery dies. Only when it dies you can charge it. You can charge as you please from then on.
Note: If it does not reach up to 100%, go to CWM and clear battery stats.

Which other firmwares? Anything UCKK6-based has known documented wifi drain issues.
The usual applies - look in battery statistics, use BetterBatteryStats to hunt wakelocks.

THIS DOES NOTHING ON ANY SAMSUNG GALAXY S DEVICE!
never tried the battery calibration?... does it actually work or no?
have you installed any new apps recently? those apps that use a lot of apps in the background are a pest to your battery life as they usually won't show up in the battery monitor. try disabling your data when not in use and see if that helps. if the current rom you are on does not have a toggle bar with data use the "data enabler widget" by Farproc.
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.

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'...

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?

Good news that you are not alone. Based on my premature calculation, only 10 out of 100 (that's 10% ) ICS ROM users have good - great battery life, meaning the rest is having worse. Mine is falling into that group. I never have great battery, only so-so and below average.
Also as Nick has mentioned, asking for which best is a NO NO here.
One might be good for me, doesn't mean it will be good for you and vice versa.
Try them all and pick one that best suite for you.
My 2 cents......I know you have read this several times - but battery life is really dependent on a lot of factors - your AT&T signal, rogue apps, data sync frequency, CPU governor etc. etc.
read Entropy's excelled thread on battery drain on this forum.
i tried out a few GB roms over the last few weeks and really did not notice any battery improvement over ICS.
Currently running cMIUI with xxkernel and it is really working out great as in the battery easily lasts for the whole day.
I remember when I was on stock GB I could go upto 2 days on single charge - but that may be due to the battery being brand new. I have read that the battery in SGS2 really degrades fast
I have 2% drain per hour when doing absolutely nothing, screen off, wifi off, gps off during 8 hours overnite.
While someone has reported having only 2% or 3% drain over 8 hours overnite.

Have you tried using "Better Batter Stats" to see what is causing the drain?
I have been using AOKP since Task brought it to us and I average 1% every two hours over nite.

I got BBS v1.7 for a while, that was absolutely no help.
I installed BBS 1.8 for about a week. Based on their info, I got the "multipdp" along with some other things (such wake-lock) cranked up big time.

I'd also recommend using CPU Spy in conjunction with Better Battery Stats to see if the phone is able to enter deep sleep.
I don't get as good as you. . .I average about 1% or less per hour overnight. But that's with wifi on, periodic syncing of 7 accounts, scheduled backups and cache cleaning going on.

My understanding is multipdp will show when apps are waking the radio to use cell data - each wake instance results in a minimum of 6 seconds of wakelock. Switching to wifi when you are idle "should" eliminate this wakelock.
I could be wrong here...dig into the known battery drainers thread from around the time the first ICS roms were being tried on the i777. There was some discussion of it...it is a renamed version of some other wakelock in GB.

That's what I said, "maybe 3G/H+ toggling".
I believed that if I left wifi on overnite, do nothing, I still had 2% drain per hour.
Let me completely turn off data tonite and see how thing goes.
errrrr I have a huge problem with my battery. I've been testing various ICS roms and kernels(aokp, foxhound, serendipidity, fluxxi Kernel, siyah 3.4.3.,Neak) and all of them with the exception of serendipity w/siyah kernel, drain my battery real fast.
Not really sure what the problem is but when I look at what's been using the battery its most of the time either screen (which is understandable) and android os? I went to bed last night leaving my phone at 100% and woke up to find it at 52%. When I looked at what was using the battery it displayed, 93% android os and only 3% cell standby??(btw Foxhound ICS, Siyah Kernel) Maybe I have to many things updating/syncing?
When I first got my phone, 2-3% battery drain overnight was one of the things that amazed me about stock gingerbread on the i777.
I've flashed alot of roms since then, and so far, no ROM can even touch that stat.
Hi,
I've been flashing roms onto my phone for months now and what I've realised is that the battery life is always awful. I hardly ever get past 10 hours, with just 1 hour of screen on time as my battery drains in stand by. I've tried cm7, cm9, perfect galaxy, miui, stock and many more, but my battery life always seems to be the same. Currently I'm running cmiui (latest version) and still battery is draining very fast. I read about people having amazing battery life on a daily basis.
My current battery life drains by 1% every 2-3 minutes of screen on time and about 5% of drain when in deep sleep or stand by an hour, sometimes even more. I use betterbatterystats, cpuspy and gsapp to monitor my battery but nothing suspicious occurs. Usually my 'awake' time tends to be 50% higher than my screen on time according to betterbatterystats, however all the wake locks tend to be kernel related. Changing kernel doesn't change this either. I've literally tried everything, installing several kernels, modems and calibrating my battery every time I flash a new rom.
Also what I realised is that my phone frequently overheats near the camera and even sometimes reaches 50°c.
I would appreciate it if anyone could help me on this topic. It is really frustrating that I cannot get through a day of even light use of my phone, which makes it almost unusable as I'm always concerned about my battery. I've also tried several batteries, so the problem doesn't lie with the battery.

Everytime you install a new Rom/Kernel you have to wait for it to settle down (About 2 Charging cycles). If I flash a new Rom to my device Batterydrain is very high too at the beginning. What you can do is install a Rom and a kernel which supports undervolting and underclocking.
I use Resurrection Remix ICS 2.6.1 with the Siyah 3.5.2 Kernel with this Voltage/Clock settings (LESS AGGRESSIVE UV VALUES with -50mv and not -75mv undervolting):
http://forum.xda-developers.com/showpost.php?p=26755476&postcount=850
With this settings I get 16 - 18 hours easily and with about 2 1/2 -3 1/2 hours of screentime and also about over 4 hours of listening music and doing other stuff of course.
Everytime you undervolt/underclock make a Nandroid backup!
Thanks, I've heard about the battery charging cycle before, I'm new to cmiui, flashed it yesterday but I've had cm9 on for about two months and the battery life was horrendous. I will try the undervolting and see how that goes

Yes but it`s no thicker than your speaker part of the phone.
I'll have a look at it, I've re calibrated my battery this morning and ismt half bad so far. Its 9 o clock now and sill have 38% left with about 1.5h of screen on time, phones been unplugged for about 10 hours. I've used the undervolt setting as suggested but still loose about 4% of battery in stand by each hour. On comparison my mums iPhone 3gs looses about 1% every 3 hours. Surely the android battery isn't that much worse

Get cpu spy from the play store to see if your device is deep sleeping. Also, you can try 1900mah anker battery. I got two and a charger off eBay for $25 can. Definitely a good deal

Mysterious indeed, all I can suggest is what I would try which is to give a custom rom call slim rom a go after full wipes and format system. Its a stripped down rom and always gives good battery life as it's so lean. Hope you find a fix soon all the best.

that combined with the rom OLLO MONSTER gives me awesome battery life
I might have to invest in a new battery. As I said before I've upgraded to a 1800mah battery and using that but the difference is minimal. Also I have CPU spy and it goes into deep sleep quite a bit, awake time however according to betterbatteystats tends to be about 30-40% higher than screen on time.

Hi,
I'm a new poster @ xda but have been a fan for quite a while.. not really the forum type so I haven't posted.
I have a question about replacing the battery in an i9100 (coming from the stock battery to a Replacement 3.7V 3500mAh Battery bought off of dx.com (sku: 73784).
For a while now, I have been unable to calibrate my battery correctly.. or maybe it's just my battery itself that's been giving me less than 4 hours idle.
I would like to know if there are any steps I should take before inserting the new battery... if anyone else has done this before and is reading this post I'd be very grateful for some advice.
I don't want to screw up the battery stats and the new battery itself.
Currently running:

CM version: 10.1-20121223-NIGHTLY-i9100

U cant calibrate the battery by just deleting the battery stats.. just leave it for a week or 2. Then it should calibrate on its own. I m using andriod phones from 2 years i never tried to calibrate the battery i just ignore that. For me sometimes the battery percentage suddenly moves up by 1 or 2% if kept idle then starts decreasing, dunno why till today damn sure its not fake charging. U can try deleting the battery stats and rebooting to make sure it s writing the new battery stats. But it never works.

So you are saying it doesn't matter what capacity battery i am switching to, it will calibrate by itself?
Yes after few charging discharging cycles... Its will calibrate automatically. :thumbup:

hey man i was also thinking of switching to similar kinda battery like yours. But i dont think it is 3500ma. So could you post how long the battery last after using it for few days??
If you're on ICS or JB, you don't have calibrate your battery because every time you charge the battery to 100% all your data and stats are deleted and the service begins to collect info again. You read all about it here and here.
Battery calibration is a myth and nothing more for ICS/JB users.

For a while now, I have been unable to calibrate my battery correctly.. or maybe it's just my battery itself that's been giving me less than 4 hours idle.
I would like to know if there are any steps I should take before inserting the new battery... if anyone else has done this before and is reading this post I'd be very grateful for some advice.
I don't want to screw up the battery stats and the new battery itself.
Currently running:
Android version: 4.2.1
Baseband version: I9100XXLQ6
Kernel version: 3.0.15-CM-g53f5eb1

You should be getting more than 4hrs idle. Try better battery stats to check the wakelocks and cpu spy to see if your device is deep sleeping

Sure thing. I've been running the battery for 24 hours and I'm at 80% left. Medium usage.
Well this is nice. The extended battery gives me almost three days of usage. And this is the cheap 3500mah from DX. I just hope it doesn't blow up
.. I also reset the fuel gauge chip.

Anker battery is what I use.. It gives me extra 1 day of usage.. better than the stock
