[Q] Fast battery drain after gingerbread, anybody else experiencing it?

Well after many many tries with topogigi's rom i had a lot of battery drain, after a while i thought its probably ok cause its a gb leak, probably its not that bad.
well after few days using it i decided to change back to froyo so i changed to FR19 from modaco but i have the same drainage really really big and really fast, i use the wifi for like 2 or 3 minutes and it goes down like 5 %.
My question is this normal? is my battery broken?
i did the calibration couple of times, i checked the usage of battery, just the "0" and "1023" proccesses using a lot of battery, i also checked if it was some app runing in the background but nothing seem wrong.
can you guys help me with these issues do you think i should change the battery or just keep calibrating it.
BTW i also read about how the battery Mv should be at 4200Mv when its at 100% but mine is just at 4170Mv and suddenly goes down to 4112 or less.
I hope you can help cause this is really annoying me a lot.
Greetings

Did you do a factory reset after updating to gingerbread, you need to do a factory reset, after your battery should be fine, make sure to take your SD card out.

Gingerbread is not battery friendly. With tweaked ROMs and tweaked kernels you can have correct results (see my config below), but Froyo 10d is stilll a reference hard to reach...

this could be many diff things, what i would do is 1 of 3 things:
1- try to calibrate it again
2- try a new kernel (maybe an sbc kernel, it might work better for you)
3- maybe try to flash a new rom for a bit and see if the rom you are running at the moment just doesn't like your phone.
at the moment i am running the decks rom for gingerbread and svz 2.2.1 kernel, however i just like to test new things but what has worked the best for me is the godmode (V9) kernel. i stopped using it because he is no longer updating his kernels but with godmode kernel and cm7 my phone lasted me a total of 1 day and 6 hours on 1 charge.

well thanks a lot for the help green arrow, what i did know was i charge full on and off after that delete battery stats manually calibrate it with battery monitor widget then turn off charge a little bit again turn on delete battery stats again and reboot this worked for me from 9:30 pm to 8 am just wasted 8% sleeping but anyways i thought it was too much so i checked better battery stats so there is a process called nvrm daemon the weird thing is that i dont have an overclocked kernel and im not using daemon so i wonder what it is.
if you want i can attach a screencap so you can help a little bit with this oddly changes with my battery.
Another thing is during night there was some changes it went from 2mh to 60mh then it start going down until 10mh at 7:30 am, if you want i can add the history report from battery monitor widget.
And finally im using gr4 Modaco's with stock kernel. Btw i changed my RIL to the v20j version the one that came with the rom and it seem pretty good after 10 minutes it sticked to 2mh.
well im gonna take some screens and upload them for you.

Some screens so i can get some more help

this may not be much help but, turn off your internet (3g/2g) and your wifi, and your 4g if you put it on, and your sync. let me know if you see some change. if you do then just turn on your internet when you need it but leave it off on a normal bases.

Huge Battery Drain ?? plz help, tried everything

Hello friends.
Using o2x from 2 weeks.
Tried lot of roms, all kernels etc.
but what i get average 1 day use of phone, 17 to 20 hrs (less 8 hrs of sleep then it comes to 9 to 12 hrs). with normal use.
1 hrs calls, 0.5 hrs data and remaining is here and there sneaking in phone.
i never used gps,wifi,bt etc, all are in off state.
.
now i m currently on cm7 kang by temasek with irnkernel.
still battery giving same draing.
draining 1% just in 3 to 5 mins when i m using phone (not on call or data).
and main point is i m on edge coverage, so no 2g use.
data is always off.
.
i dont know what eating my battery too much..
.
realy, i m getting upset.
i tried every kernel and every rom, did battery calibration etc.
.
Update : I forgot to mention i m using class 2, 16 gb micro cd card.
also i m using acer liquid metal's usb charger for charging.
will this affect on my battery ?
update : guys i want to mention one thing.
today i pissed of with this problem and thought it was battery problem.
so i planned to go customer care.
then turned back v20e which official 2.3 for india.
then i saw dramatic changes in my battery drain.
it was half as before, with stock thing, no apps installed, not rooted etc.
i m still monitoring my battery.
.
also one thing, is go launcher will be cause for this ?
cause when flashed with v20e. the widget show drain as around 130-150 mA.
then i installed go launcer ex, then drain was 250 mA.
.
what is ur normal drain when u r using phone ? (for those who r getting best battery life)
.
.
can anybody share his battery drain graph which taken by battery monitor widget ?

I have a similar problem, but it's likely because of 3G. With V10F Froyo, the phone drained <1% per hour in stand by, with 3G on. With V20L, and CM7 (any version of them), my phones draines 3-5% per hour. Tried anything, any ROM/BB combination, returned phone to warranty, but nothing.

OMG u r god!
how the hell do you have such a battery life?! even I am on temasek's kang!! at avg with your kind of usage it will go for less than a day :/

same with me..
hardly a day..
is there any problem in indian phones ?

See that 'better battery stats' image you put up? See the drop down menu that says 'since unplugged'? Change that to 'partial wakelock' and get a picture of it to show us the result
Also, you seem to have a lot of battery apps on the go.. are they conflicting?

i dont know

I had a problem with huge battery drain and the culprit was my sd card. I dont know why but it had problems scanning it so I think it got stuck in a scanning loop of some sort. When I removed it, all was fine.

i m getting angry on my phone.
see guys, i slept over night with 100% battery, just wake up n saw it wa 99%.
then used phone for just 20 mins.
and now battery on 92%.
now tell me friends, what i need to do ?

Do you have apps like juice defender? Accuweather? Uninstall them. They are probably eating you battery without you seeing.
See your running application?

nope.
in provided ssi was using jucedefender.
later i removed it.
same drain still

Perhaps you need to calibrate your battery (using baterry calibration app) and wipe the battery stats (via cwm)

i did it already.

My recommendation:
1. Flash vadonka's kernel (ironKrnL has good performance, but drains battery fast).
2. Remove widgets which keep accessing the net in background, stop background data over network (in settings)
3. Install AnTuTu battery saver and set battery saver level to level 2.
4. Remove SD card. Try to manage for a day without SD card. Set internal storage as SD card in CM settings.
5. End all background apps after using any app (use dr. battery saver or similar app to kill all apps).
6. Take any other precautions, such as lowering screen brightness, tick "use only 2G networks" option, dont allow automatic email syncing in background etc.
Try this for one day on a full battery and let us know the results. If it does not improve much, you probably have a defective battery. I also own this phone in India and my battery easily lasts 2 days on normal usage.

Thats normal i think. Get nearly the same results.

Try Rugglez suggestion.
Also check if your Baseband matches your RIL.(Download GetRil from Market)
And go into Settings --> Apps --> Running Apps and check if there are many Services running in the background.
Also you can try to install the Autostarts app, which lets you control which apps are allowed to open themselves in the background.

Update : I forgot to mention i m using class 2, 16 gb micro cd card.
also i m using acer liquid metal's usb charger for charging.
will this affect on my battery ?

[Q] Battery Analysis

Hello, can someone give me a hand with the analysis of my battery consumption?
I used to get 3-4-5 hours of Sceen On time. Now I can barely get 2 hours!
The same images attached are now included directly into the post:

With this last image I have no idea why it shows this. I've never been without internet, and I always have 3G coverage except in a few instances when I'm on the train going through a small tunnel or something (it drops to GPRS for about 30 or 40 seconds).
Thanks guys... I'm so confused...

cool picks, got cpuspy pics of same timeframe?
I like to cross reference and check if numbers add up.
Did you switch roms/ kernel lately, or update?
Battery getting full charge? mv?
Now the partial wakelocks are interesting. Try switching off fast dormancy by dialling *#9900# and selecting option that should/could take care of svnet.
Audioout probably by turning off options in settings then sound then all bottom choices.
the rest I am not sure, google partial wakelock and the service name.
Other then that, if nothing has changed except battery lifetime. Try safe kernel, then completely go to zero situation where you were getting the better battery life, then eliminate other apps perhaps.

Sorry I should have mentioned that I'm on full stock 2.3.6. I don't really like the ics builds. No other apps to measure.
The kernel is always the highest usage on my phone. What can cause that?
I'll still CPU spy and run it tomorrow and republish here. Thanks for your reply.

Hello zkyevolved, which version of BetterBatteryStats are you using?
I ask this because on my device, under Other and Since unplugged options, there is no Deep Sleep entry directly below Wifi Running. The entry shown directly below Wifi Running is Awake.

Hello! Thanks for the reply. I checked my version and it's 1.9.0.0. It was just updated the other day if I recall correctly.
I will update again today after a full days use in the battery. I'll post again with screenshots from both applications.
For the moment I've only disabled fast dormancy.
Sent from my GT-N7000 using Tapatalk 2

awesome. You know analyzing is pretty difficult on android lol. sometimes I get frustrated and just reset to starting conditions and reinstall everything. Which is safe on gb, not ics due to superbrickbug triggers in ICS kernel.
Analyze first though Am interested in results.
If battery life is important and you dont mind warrantee, I can recommend the k2-11 or k2-12 speedmod kernel on gb roms. It was best batterylife for me 4-5 hours full screen on time.
Sent from my GT-N7000 using Tapatalk 2

a quick recheck, in current pictures you have 11 hours of measurement time with only 5 in deep sleep and 2 hours onscreen time?
That means 3 hours phone is awake. So it does seem classic deepsleep issue. I am no pro btw, but thats what I suggest monitoring for now.
When phone doesnt deepsleep cpu cycless on 200mhz doing nothing, that consumes energy, we are looking to minimize that.
Some of the stuff I mentioned earlier, partial wakelocks is whats actually keeping phone awake. I hope the fast dormancy off takes care of some keep awake time.
Now when measuring dont check phone every five, ten, twenty minutes, sometimes it takes about 15 min to go to deepsleep, thusvyour manually keeping it awake. Been there done that.

Hey everyone! Here are some updated screen shots:
This was my activity today: I did listen to some music, I mostly answered messages. Browsed very little. I skyped over HSPA for about 5 minutes. I went for a quick jog with endomondo using the GPS and music in the background via bluetooth for a total of 30 minutes. I used wifi for most of the day. As you can see, for a 2/3 of the day it was in deep sleep, while the rest was a mix of other speeds. I imagine 200-500 was the light usage (endomondo with screen off, bluetooth headphones, skyping OTA, etc.) and when the screen was mostly on and browsing, taking screen shots (I took a lot today, to annotate the screens I was looking at), etc.
Thanks everyone for your continued help.
Ohh, and the SVNET service is still there, I turned it off yesterday, and then today at around 5 o'clock I saw that I had about the same battery left as other days, so I turned it back on again.

ok then its something else keeping svnet up. Dunno about that.
For the rest its best for comparison of stats to measure same timespan, so reset stats when you unplug phone.
Anyway it is deepsleep issue, your phone is not appearing to go to deepsleep ideally.
Cause I cant make out the numbers from what I see, and what it is keeping awake, I recommend starting new. So save messages with an app from play, apps with titanium backup, and efs folder if you never saved, check my thread on that. Contacts and calander in gmail. Photos manually Backup on external sd card and remove after.
On GB do a factory reset with code in dialer ending in 3855, that completely resets device. That should do the trick. I think from settings storage format sd card, not sure if factory reset does that.
If you dont care for warrantee then perhaps speedmod k2-12 kernel is a good alternative to stock gb kernel in terms of battery life
That should fix it. Just dont restore apps with data, let it repopulate itself, that way if something is messed up there you can catch it.
If I am missing something, and anyone reads this, I am keen to learn

XXLS0 JB killing the battery. Anyone else?

Anyone else experiencing worse battery life going to official JB? My official ICS battery was much better. Much. I even did a hard/factory reset after I updated. Ive even disabled a lot of the "new" features like google now and multi view. Anyone have any tips? I used to last til 15% by 10pm on a single charge now im at 15% by 530pm... ugh. Any way to easily go back to Official 4.0.4 Germany?

When I check my Battery stats it looks like the screen is using everything. Im keeping it on the same settings I had on ICS. No auto and about 45% brightness standard.

I have the same feeling about the german jb official rom.
Screen is taking up almost all the battery. Any ideas to improve battery life? I usually do the recommended tasks such as no background process, low bright screen, few widgets and so on.

My wife's Note on LSO has been having terrible battery since the update. The drain is massive.
Too bad, she really likes the multi-view, but as-is, it's impossible to keep this ROM.

I have same situation- display uses more then any other rom in past...
What rom is best in bartery life- no matter GB, ICS or JB, probably custom with custom kernel. it is not important for me as batery life?
thanks

My phone idles alot and on lsa i noticed it loosing alot of charge just idleing
so much so i rolled back to 4.0.4
the final german release is just as good in my case for long idle times as it was on 4.0.4
cant say on long term screen use

I have same problem. After installing BetterBatteryStats
http://forum.xda-developers.com/showthread.php?t=1179809
I have discovered that AudioOut_2 wakelock is problem. After some investigation it seems problem is Skype or Viber. Currently i am in testing process. I will post any news here.
Update: after removing Viber, problem is solved :facepalm:

do try enable power saving...it limit your cpu max 1ghz only, thus could save a bit

@rames
I do not have viber and skype...

Whats the best way to rollback to 4.0.4? Thx

install CPU spy betterbatterystats and check for wakelocks.

I was getting 8 days of use out of LSA (I keep everything off GPS/WiFi/3G Data)
With LSZ I am getting around 5 days of use ... with the exact same usage ...
My CPU is almost always in Deep Sleep so I am starting to suspect the new baseband LSO (modem.bin)
P.S. Stock LSZ with PhilZ 4.63 Kernel+CWM ...

I had same thing so I simply did the following :
Enabled power saving then forced stopped every app which showed up in running services which was not needed and battery back to nomal now.
I found that maps and voice talk kept my device awake a bit so if you don't really use them daily then simply disable.
I seem to remember it was the same with stock ICS when first released then it got better so fingers crossed.

Guys why don't you follow ahalford's thread about battery life / wake locks? You'll find a link in my signature.

Only thing I really need in 4.1 is blocking mode.. I plan to back on rocket v12. Is there any with better battery life?

You have a lot of wake locks and apps.. These battery saver apps really don't help that much. Use betterbatterystats to find out what those are and check the wake lock thread in q&a sticky .

Galaxy Note GT N 7000
Try the Ultimate Jelly Bean ROM....it should answer your questions on battery drain. Check the forum for Ultimate Jelly Bean ROM

that's a problem of Germany JB, battery short life and can't use airview

Try LSF Trinidad and Tobago rom or Jonrom which is based on it. It has better battery life for me than german LSZ. Airview fix also working.

[Q] Is it normal for my battery to be so bad?

Hey all!
I've bought my Optimus 4X HD recently. I'm loving everything! Except the battery...
Today, I've tested it again and here's what the battery is able to do!
- 6 hours of standby, 3G and Sync enabled
- 4 times checked mail for like 4 minutes total
6 Hours later: 30% remaining.
Is it normal for this battery to be so weak? I've "calibrated" (drained to 0% and charged to 100% - left it for a long charge the first time too)
If it's abnormal I'll contact the helpdesk and see if they can replace my battery, just want to be sure if it's normal or not.
Software is latest available, non-root, very few apps -- verified with taskkiller of AVG: nothing is running in background or anything.
Thanks!

I think there are some wake locks denying the system to go into deep sleep.

I usually get at least fourteen / sixteen hours on a single charge when I unplug it in the morning before work, varies with how long the Wi-Fi turned on, and I get at least three hours of screen time, one or two of voice calls. I also have mobile 3g data always on with alerts for email, Facebook and Google+. Usually I listen to music for about an hour and half too. I'm running the 20a euro rom official, rooted. Try factory resetting and rooting to remove bloatware and LG logging software.
Hope this helps!

Hey all!
I've bought my Optimus 4X HD recently. I'm loving everything! Except the battery...
Today, I've tested it again and here's what the battery is able to do!
- 6 hours of standby, 3G and Sync enabled
- 4 times checked mail for like 4 minutes total
6 Hours later: 30% remaining.
Is it normal for this battery to be so weak? I've "calibrated" (drained to 0% and charged to 100% - left it for a long charge the first time too)
If it's abnormal I'll contact the helpdesk and see if they can replace my battery, just want to be sure if it's normal or not.
Software is latest available, non-root, very few apps -- verified with taskkiller of AVG: nothing is running in background or anything.
Thanks!

Very few apps installed by you... there is a lot of stuff running in background that you don't even imagine.
Search for the threads about "battery drain" and you'll get some more info.

Do you run the new 4.1 Jelly Bean? There is some huge debate going on, how the update affects battery life. Personally, I ran into huge battery problems after updating to 4.1. The drain was especially heavy during the night, when I usually active airplane mode. With ICS I lost about 1% during an 8 hour night, under JB it was 20-30%. I read up on the threads in this forum and followed many suggestions. I started to monitor battery drain with different apps running/frozen, wifi, 3G, airplane mode enabled/disabled and so on. To analyse the battery I found the apps "CPU Spy", "Wakelock Detector", "GSam Battery Monitor", and "Battery Log" helpful.
But to be honest, I am no "android pro". I monitored my battery drain for over a week and did not find a satisfying solution for the problem. Thanks to this forum and many excellent posts I managed to roll back my phone to 4.0.3 ICS. Now my battery drain is the way I remember it and I am happy again
For me, this solved the problem. Although I do not run JB, and some of the enjoyable improvements it had, anymore. I know that for some people rolling back is no option. If you cannot locate the battery killer easily and you are willing to play around with your device (rooting, freezing apps...), you might as well roll back and give that a try.

You should explore your device and your stock apps...
My battery last in JB for so long as in ICS.
If there are differences they're small.

Yes!
Thanks all, very useful replies!
I've tried simply factory resetting it and, for about 3 hours it stayed on 100%, 2 hours on 99% and etc, very awesome!
I then set up my mail and other things and it went bad again. I had this sync symbol in my notification bar -- no clue why it was there all the time.
I googled why it was there and it's because the sync fails so it keeps trying. I removed the picasa for the email account (because uni mail doesn't support picasa and other google services) and my battery is top notch again! For now at least .

Looks like you're on WiFi which has good standby time. 3G standby is not good at all. That's when baseband_xmm_power starts acting up for me.

Following is my Battery usage still left some 17% with normal usage.

I've had terrible battery life... But when I went to cyanogen mod... It's been great for me ever since... Well two days actually. Lol

For me the same result with HSDPA. From 8:00 to about 15:00 oclock 15-20% of battery Just IM+ on, sync, some web browse + maybe one hour some games like beach buggy blitz or subway runner.

mine is bad because of the baseband_xmm_power wakelock, had this on stock 20A but didn´t had on 10h... as far as i can search, there is no solution other than revert to old 10h....
I bought a spare battery so i never run out of juice! Reverting firmware is not an option for me.

baseband_xmm_power wakelock, same problem here, battery drain cause this at v20A Jelly bean.

i believe this wakelock is affecting every phone since 20A, just install betterbatterystats and see it plague and suck our battery juice
