Hi guys, I recently rooted my I9300 galaxy s3 and my first ever flashed rom is cyanogenmod 10. Overall I'm pretty impressed with the look and feel, but it does appear to be draining the battery more than than it was before rooting and flashing.
I read somewhere else that no matter what rom you flash, battery drain will always be high for the first few days before settling down to a more acceptable rate. Does anyone know if this is true?
Thanks in advance
True until battery re calibrates itself .

Thanks, is there anything I can do to aid the process, or should I just leave it to sort itself out?

You calibrate by charging to 100% and then wiping battery stats (from cwm for example). That should aid it
The battery will settle on it's own, manual battery calibration is not necessary.

-_- OMG. Are you serious right now... Do you not know anything? Wiping that file does nothing to help the battery. It is wiped every time you charge to %100 or flash a new ROM. It helps nothing.

The battery calibrates the battery stats play no part in the battery calibration as posted read Dianne Hackborn Google Engineer post .
Moreover, no custom ROM will ever match the stock as far as battery life goes.

What application is everyone using? I'm getting poor battery with 0.2.0 beta and I used one and it still persists.

Charge to full, boot into CWM and wipe battery stats.
Use until device dies from dead battery, recharge to 100%. Use as normal for a couple days. It should get better.

yea read it was a myth a while ago
Flashed cm9 today and now my battery life is horrible, when it it's on the charger it takes forever to charge.
I had that problem also so I wiped everything and formatted everything and Redlands everything starting with cm9 v 0.1.0 2d , then flashed cm9 v 0.2.0 . Everything great

myth
maybe a myth and from everything i have read (that article included) it seems to be. but im ok with the placebo affect or whatever bc i at least FEEL like it has helped since i did it after getting on cm9 beta 0.2.0 or whatev. not on beta 0.3 battery has been sucked hard as all get out, but such is life.
I have a question/comment about this. When a ROM is flashed I always wipe and format /data, /system, /cache, /davlik-cache, and factory reset. At this time I power down and recharge although the recharge may not matter as the lowest I've been was 85%. After recharge I boot into CWM and wipe/factory reset again then allow the phone to reboot. Isn't the batterystats.bin file in one of those places I wiped/formatted?
Once it's booted I just turn off and power up again then activate. Out of all the different ROMs I have tried this usually works very well. There was only one time my battery life was poor after flashing and I tried a battery wipe app and it still didn't help. I finally attributed it to the ROM and flashed a different one. Following the same process the new ROM was installed and battery life is great again. Did this yesterday flashing Rocko unlocked 3.0. After 4 to 4-1/2 hours of heavy use, when I say heavy I mean heavy, I am still at nearly 70% battery. If it works the way it looks to, I'll be getting at least 10-12 hours on a charge, probably more.

Calibration
So what you are saying since I have a Photon with an extended battery even rooting it won't calibrate the battery. It sits at 1% for hours. Had an HTC prior and didn't have this problem. Waste of money getting an extended battery when you don't know when it is going to die on you.

Not at all. What I'm saying is I personally don't use ine as I wipe battery stats as part of ny flashing process and do my first boot on a new rom with my battery at 100%. That works for me.
If you're switching to an extended battery you may need to wipe battery stats. This can be done with a battery calibration app or from within CWM, if you've unlocked and installed a custom recovery.
BTW: Rooting will allow you to install and run a batt cal app but rooting alone will not calibrate your battery.

So I will be learning more about rooting. But I thought i saw where others who had extended batteries that rooted with calibration apps their Photon still didn't read correctly. I could be misunderstanding something. Newbie here.
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.

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?

Hi I have read some threads, but cannot find anything that helps me
I have 2 Original Samsung batteries, cahrged both with the dock or AC charger, and cannot reach 12 Hours
I dont have any "strange" app or something that could be draining my battery.
im Using the Paranoid Rom (CM10) and wifi most of the time
wish to know what could I do to improve my battery life
hope someone can help me
(sorry about my english)
Boot into recovery and wipe battery stats also if you have antivirus....get rid of it, drains your battery and is not needed
anyone interested in blu-ray steelbooks, holla at your boy
thank you.
so if I have 2 batteries, I should wipe the stats for both right?
and one more questions, I read and told that if I flash a new ROM, i should wait for some battery full cycles for the battery to
last longer. Does the "wipe battery stats" affects anything?

Hi
as what the first reply said, you wipe your battery stats via recovery..
but to do that, you have to fully charge your phone up to 100% first and then go to recovery and wipe battery stats..
also, any applications such as "battery savers" and "anti virus" apps drain battery.. also, wifi is a big factor in your battery drain since the phone is forced to look for connection.
I hope this helps
Wiping stats is a myth that Google engineers have dispelled a long time ago.
It won't help you at all
Use BetterBatteryStats to see which app is causing it. If you are on Siyahkernel (highly recommended) then tick "exclusive wakelock" to get more accurate ioformations.
Tip: the app is available for free here on xda

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.

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.

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

Hi,
I have a weird battery issue. You can check attached screenshot.
My battery percentage suddenly decreases for example %45 to % 12. Then as soon as I plug in charger it comes for example %12 to %26. Completely unstable battery stats. Sometimes after charging %100 it doesn't decrease for a while. then I reboot phone and it suddenly decreases to %89 or something like that.
2 or 3 times a day device shuts off by itself.
I have cm 10.2 android 4.3 rom and I come from omega v46 android 4.2. (I had same issue on omega). I always perform full wipe before installing a new rom.
I tried factory reset, BBS, remove sd card, reinsert sim card etc.. but I could'nt solve the issue.
Finally I bought another battery but same issue still goes on.Maybe it's about an apk like CPU Adjuster which I previously installed on Omega rom.
Can anybody help?
I am having same battery issues, my battery discharges very fast when the data network is on, my phone doesn't last 5 hours when the data service is on.

Thanks for advices but I'm OK with my battery life. In my cm rom, battery life is better than stock ones. By the way Easy battery saver is really amazing, really saves battery. I used that before but it turns off everything in extreme mod, and I can't get what's up messages or my push mails etc. Anyway, as I said before my problem is not battery drain.
I installed "battery repair (doctor boost)" APK from market. It's a paid one. It seems to solve my problem. Everything looks ok since last night. If not, I will report again tomorrow.

Hi. I searched many forums, read hundreds of posts but still couldn't solve the problem (1st post) . I see many people suffering from same problem but no one has found an answer.
I'm sure that it's about one of zip files which I have flashed in my previous roms and I don't remember.
I'm sure because I had same issue in my previous omega v46 android 4.2 rom. Although I wiped everything and flashed cm 10.2 android 4.3 rom, the problem goes on. Even I bought a new battery but still the same problem. What causes this problem? It's really weird.
