[Q] Fast battery drain after gingerbread, anybody else experiencing it? - LG Optimus 2x

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.

No, not normal. I get home with like 55-60% battery left with
12 hours standby
1-1.5 hours calls
1-1.5 hours with activities that keep screen on like texting, mails, etc
i am on the ROM in my signature.
ok is there anyway to get reduce the battery drain without changing roms if not whats the best rom for battery life??

Try using a kernel that supports UV and setting slightly reduced voltages. I am using GB's 1280 kernel, and capped the speed at 1000. And reduced the voltages slightly.
Others would be normal things like switching to EDGE, lowering brightness levels, setting wifi to "turn off when screen off", etc.
what does UV mean sorry im a newb :/ and how do u install a different kernel

UV = Under volting
1. Load the kernel in my signature (attached to this post)
2. Install the voltage control app (attached to this post)
3. Start the voltage app and set the voltages and cap at the levels based on the pic in this thread.
WARNING: Voltage levels depend on phone to phone. I would suggest starting from low values. Take off 50 from the values I have posted in the pic and use them. If u feel it is ok, then add another 25. Take it slowly checking if the reduced voltages are freezing up ur phone.
I would recommend u starting with these values: 75 75 50 25 25 0 from bottom to top.
Ok thanks diablo I will test this out tomorrow and report back

Sounds like a good old battery recalibrate is in order:
1. Connect the phone to the charger with the phone powered on, and allow the phone to charge until it shows 100%
2. Disconnect the phone from the charger, and power it off.
3. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the battery indicator shows 100% (you can use vol-up/vol-down to make the indicator come back up when the screen goes to sleep).
4. Disconnect the phone from the charger and power it on.
5. Once the phone is powered completely on, power it off again and reconnect it to the charger until the battery indicator shows 100%.
6. Disconnect the phone, power it on, and use it.
I did this a couple days ago, plus wiped stats, and as of right now, I am showing 20% after 30 hours. No joke.

Ironically, JuiceDefender killed my phone *much* faster than with me manually enabling and disabling my data connection.
IMO, JuiceDefender does nothing that you can't do yourself, the problem is, is that it constantly has to check apps to see if any are enabled to toggle your data connection.
I am just saying

I actually use my phone and I am getting these results
I have a very similar question. My problem is, on custom roms (I've tried Assonance, Serendipity, and another), my battery drains 1%/hour. This is even after a fresh install; nothing is running in the background. When I look into my battery info, it says wifi is doing the draining. I keep hearing people saying their battery life is amazing after flashing custom roms, but I'm getting the complete opposite. Am I forgetting something?
Without custom roms or anything, and using a rooted/lag-fixed (not sure this makes any diff anyway) setup, I lose somewhere between 2-3% battery per hour on standby. I don't even use juicedefender. I really love what they're doing with these custom roms, but the wifi on standby just rapes my battery.

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)
.

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.

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 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.

then used phone for just 20 mins.

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

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.

ICS update Battery Issues

Alright so like many other people on this and other forums, I updated to ics 4.0.3 two days ago and been experiencing battery issues since. But my battery issue is a bit different from what I've read about. My note has no problem going into deep sleep, when i go sleep and wake up deep sleep is at 98-99% and my battery drains about 1%. But when I turn on my phone and start using it no matter what I do, the battery drains about 1% every 3-5 minutes.
Phone settings:
- I always have my brightness at 0 and have screen filter on to make it even less bright(even though battery drains about the same with or without this on) (batter settings still show that screen is taking up most of the battery)
- With wifi on or off battery drains just as fast.
- I havnt started my new data plan yet so im always on airplane mode( battery drains the same with this on or off)
- My note was never rooted
- I basicly have no widgets on anymore because i deleted most of them but doesnt help battery life.
- With power savings on or off battery still drains the same amount
- The only apps i have installed after ics are ones from googe play(netflix, chrome, and other simple apps)/ i deleted my emulators and other apps that iv'e downloaded and installed
Can anyone please help me with this issue

You are on Stock ICS ? Go to Settings>Battery And Post the Screenshot Here. It will help us to determine the exact situation..
Sorry I'm new im guessing stock ics means official release from kies, then yes. I dont know how useful these battery ss will be because a lot of the time im either idle or charging.

Did you perform a hard reset on your device after the update?
if not, then see if you can try it and get back again with your screenshots.. don't forget to do some re-calibration also on your battery. This works on my end before. Not sure if it works on yours, but hey.. there's no harm in trying right? just give it a shot bud...

Turn off the sync. Kill Background applications and See if it works for you...
Also download Battery Calibration from play store... Open it when its fully charged and start calibration... Let your phone battery fully drained and then charge it again to full without pauses...

Op never ever ever ever ever ever do a factory reset from ANY ics stock kernel.. It will get your phone bricked.. Or maybe but just maybe not? Anyways will you take the chance?
I was on 4.0.3 stock and yeah the battery it's horrible.. Don't know why the phone barely goes deep sleep.. Check this with cpu spy free app from market
Since the phone upgraded itself to 4.0.4 I have been able to run 14 hours with 5 hours screen and the phone its always on deep sleep

yea i knew theres a huge risk involved =/ , is there anyway i can update to 4.0.4 because it's not showing up on kies
Yeah following the several guides around.. They all lead you to download 4.0.4 and a gingerbread rom from Sammobile, downgrading your phone to gingerbread by flashing it via odin and then flashing ics 4.0.4 via odin also .. So go ahead and read some..
Cheers

Check Android Development Section...
cpuspy and betterbatterystats to check partial wakelocks and whats keeping phone awake. A gazilion threads on that. read them. You need these as Samsungs analytical view state nothing usefull, they need to fire the designer of that.
Next to this I see lot of screen on time, how much time roughly is that in total, you are actually using device?

my phone doesn't have the deep sleep problem people have. my on screen time is about 6 hours before it drains completely and by on screen time it could be on the home screen with no wifi/net and no apps running with just the screen on, and the battery would still go down 1% every 3-5 min
So ics 4.0.4 came out for the UK version of note so i updated via kies. This didnt fix battery life at all, in addition iit came with another bug where my phone gets hot and drains battery when turn off the screen after playing any media file....So my question now is can i root 4.0.4 if i have the Emmc bug?

[Q] Weird "battery drain" when lightly using the phone

Hello !
I just bought my P880 two days ago and everything is great except one thing: battery drain. It is not occouring in background when phone is in Deep sleep, it doesn't lose charge while it's sleeping, but when I just unlock it/start using it, it just starts draining.
I have rooted it, and unrooted using SuperSU. The thing is I haven't experienced that kind of drain yesterday, it was working fine except drain caused by bad signal (badly inserted SIM).
Usage by Android System is at 50% over 5 hours, Screen is at 9%. Awake graphs are the same as Screen on graphs- no wakelocks.
I have these apps installed:
Prey Anti Theft
Skype (not running)
Adobe Reader
SoundHound
Disco Light
QR Droid
Sygic (not running)
X-plore
SwiftKey 3 keyboard
WiFi, GPS, Data, everything turned off except mobile signal
Running Internation version with Android 4.0.3, Kernel 2.6.39.4-00001-g0f9182c
Mobile network type is EDGE:2 with mobile signal -70dBm
I'm first time android user and this is my first problem so I tried to include as much info as possible.
Thanks in advance
I see 2 mayor issues, first is the android deft app, it may be running and trying to sync but bcz the data is off it will try to connect foreva.
Also, edge is (in other words) ROAMING and this forces the antenna to use more power to get signal from another provider, it get worst if you have a phone with sim card.

Thanks for pointing that out, but I have disabled every sync and I have set phone to 2G mode only, the reason is that UMTS signal was low and was draining battery even more.
I am only losing sharge when just doing random things on phone, even if that means only adding/removing widgets/apps on main screen with WiFi off.
Then you must try the Deodexed version of v10f, removing the bloatware with the script in the same thread.
The issue may be some lg apps that are running in the background so doing this will have 6 hours in standby time with 100% still, like me (if I turn all radios off ).
I have just woken up, while sleeping (9h) phone was awake for about 50%, no wakelocks but there were 30 alarms from Android/Google maps ans 29 alarms from com.google.android.gsf
Hope this helps.
I may try custom ROMs if nothing else works.
While typing this message I have lost 7%.
Similar state here as the OP. Got the phone two days ago.
All is good, it rooted OK, Directory Bind works fine, phone runs like hell (about 10 times faster than my old Galaxy S) BUT it drains battery like a genuine power guzzler.
Ok I get that according to the performance you get, it comes with an accordingly high power draw, so I don't ***** about it, I just want to know if this is normal. I mean I played 2 hours and 15 minutes of Sprinkle and the battery died, starting from a full charge. Screen was set at 50%.
GPS is off, Bluetooth is off, no 3G mobile network and screen is at 50% brightness as I said. There's an NFC icon on the notification bar next to the battery icon, which I am not sure if it should be there.
Here are a couple of shots from the battery section of the phone and from Battery monitor widget if these help.

Please note that as the OP said, the phone consumes nearly nothing when idling. Firmware is 10f.
PS I am not trying to hijack the OP's thread. I just noticed the same behavior and I'd like some help on the same matter, as well as to contribute in whatever way I can. If the OP is offended somehow, I will gladly start a new thread.
@psolord No, not offended at all. I'm glad you posted actually.
My phone has encountered 20 more Alarms, wake ups since I left it standing:
com.google.android.apps.maps Wakeups: 50
com.google.android.gsf Wakeups: 45
You can see pictures below, the drop on the second picture happened when I was writing me previous post from P880.
- I am also rooted again (after factory restore)
- I have reenabled 3G networks but the signal is only at about 50%.
Any additional info please ?
Ok buddy, so we can keep discussing it here together.
For the matter at hand, I see the same behavior, when I unlock the screen, it's like I have opened a whole in the battery.
It dropped from 85% to 65% just from downloading a new map (500MB, 20min download on a slow wifi) from Sygic downloader. I mean this can't be right, right?
I also checked cpu spy and it reports the system 75% at deep idle, 15% at 51Mhz and the rest are 0% to 1% up to 1500Mhz. So if the cpu has so little operation, what on earth is draining the battery?
I wonder if we could be looking at a bad battery batch.
Is there an app that reports exactly what activity consumes power and how much?
Indeed, the hole in the battery.
I even restored to factory from recovery mode since I screwed up the root, so it was just stock, but guess what, nothing has changed :crying:
I really hope this can get fixed, else I'll get a replacement.
I hope someone from this forum with more experience can help :/
I think I am onto something.
Can you please check how is the phone doing if you disable everything under location and services?

I am going to try this, I am also talking to LG Support right now. WIll let you know when I get more information.
I disabled everything, and I didn't see pretty much any improvement. LG Support suggested me to return the phone.
Pretty much draining the battery atm so I can charge it back to 100% and use something like Battery Calibration. Maybe it can change something.
Yeah indeed I was onto nothing. Nothing changed for me either.
Playing 30mins of a 720P resulted my battery dropping from 62% to 50%. I also used the gps for the first time with Sygic (Jesus even the GPS is lightning fast) and the battery went from 50% to 30% for a 20 minute ride. It seems that my phone cannot give me more than 2 hours of use. That's just silly.
BTW do you or anybody, know of an app that can show battery usage per app?

Stock application ?
Also you can use Better Battery Stats to see if there are any wakelocks or anything is waking up the phone etc.
What is happening right now is rather strange, I disabled screen turning off (trying to drain battery to 1%/2%) looking at stock battery app, it seems to be stuck at 21% and it's not changing.
The stock application does not do so much analysis, but the batterystats you used above seems more like it.
I am getting panicked and I miss some stuff haha. Ok lets cool.
It makes me sad that we don't get any input from the community. Something like "yeah this is normal, live with it" or "your phone is faulty, take it back to the shop for a replacement" or something.
Agreed, ANY, ANY kind of input would be appreciated, but I guess we are getting none.
I am going to fully charge it today, do some stuff and report back tommorow. Also anyone, please do post any suggestion you may have.

Maybe this has to do something with the built in power saver. Maybe it kicks in when the battery drops to the 20s and stops whatever is draining it.
I am thinking trying some battery saver to see if it does the same thing but from the beginning of the full charge.

Actually I have disabled it when it asked me if it should turn on. So I guess nothing to do with that.
I am going to backup now, fully unroot and somehow get it to pure stock. Than I'm probably going to exchange the phone in case battery life doesn't change.

[Q] Battery Drain

Yeah i know, the same old problem but bear with me guys.
So i use Carbon..latest version (11/19) and i've recently decided to try these 2 kernels: CroPol kernel and PA kernel by tenshi and so far i've noticed no change in battery drain...it drains VERY fast!
So my questions to you guys and i'm gonna number them so they are easier to follow:
1- Is there something wrong with Carbon these last several updates?
I've bought a new battery and nothing changed. Should i migrate to a different rom?
2- Which kernel is best suited for Carbon or for S3 mini in general? and can i undervolt it?
3- I'm a super heavy mobile data/ Wifi user so what's the best governor/schedule combo to use to save battery...i dont mind it being slow as long as it saves battery. I use Powersave/noop all the time but still no use.
Please help!! :crying:
Thank you very much.
same Problem :/
I got the same problem since using the new Carbon version in KK 4.4.4.
nothing helps until now.
what i tried so far:
- formattig everything in EXT4 instead of f2fs
- factory reset
- flashing Stock rom
- flashing cyanogenMod 11 from novafusion.
- using battery calibration
what i noticed in Carbon:
-taking pictures with flashlight were killing my phone, restart with 30% less battery power. this bug appeared when using f2fs formatting but not ext4.
what i noticed in cm11:
- after normal restart also 20% less battery power.
what i noticed in all roms i tried after the bug appeared:
- when battery has around 20% battery phone will just shutdown and restart with 1% battery :/
can anybody help ?
Same here with but with random boots! (see the thread)

Same here after using f2fs on AOSPA and CM11. Now I'm on EXT4 + Stock Rom and I've got 10-20-30% battery loss after reboot.
However, battery indicator is wrong, but battery will last as if the percentage were still as before the reboot.
Also getting huge "Android OS" battery drain with no explanation from BBS
There's really no way to revert battery fuel gauge accuracy to stock behaviour?
Today i noticed also the random reboots.
When the phone was charging over the day and i tried to open SMS or any application, it suddenly reboots with 20% less battery power.
i think this bug is caused of the f2fs patition. i will try to flash a pitfile and stock again. the last time i didnt use a pit file.
i will let you know what happend

this has most probably nothing to do with F2FS or any file system. i am using ext4 and i have the same issue.
Flashed stock rom with .pit file and nothing changed
Also I'm sure this has nothing to do with battery health, since battery lasts the same as before

hopefully tomorrow i am getting my new battery and i'll see if it is a physical battery problem (mine is a year old). because on slimkat, carbon and cyanogenmod there is this problem (and stock rom as you have shown here). if this ain't a physical battery problem, may god help us (i'll be forced to buy a new device)

Mine is one year old too, as well as the ones from other s3 mini users here on xda that have had this problem... let me know if it's worth it! I'm really getting crazy on this one...
nothing changed with pit file flash
i noticed:
no installing of new apps (SD-Card interactions) except of wakelock detector
just using WIFI, G3 SMS and Phone
was the behaviour normal! around 10% battery loss in ~5 hours
But when i pressed restart to reboot the phone!
it Crashes continuesly and battery jumped to 20%.
so the phone is doing something in the bootup process, which has a huge battery drain!
ill try today evening to flash previous CM with f2fs. I don't think that the battery is damaged. otherwise the batteryloss would be consistent.
Ok guys I'm not taking credits of this method to see if something's wrong with your battery but this is it
Take out your battery and place it ona flat surface, then spin it horizontally on both sides, if on one of the two sides it spins and doesn't get stopped by friction then the problem is that the battery is going to inflate and this means the battery is going to die
This is my case, so I'm gonna buy another original battery and let you know
If it isn't the problem for you, then it's a software problem with partitions

oh yeah. my old battery was definitely swollen. not much swelling can be seen without taking the battery out but one can see it clearly on a flat surface. it spins right round
with the new battery
it's still early to tell whether it was definitely a battery problem or not for me, but it surely looks that way. here are my stats after somewhat heavy* first usage:
so, do the "battery spin test" on a table like @h4wkst3p suggested. if it spins, no good i am afraid
*: by heavy i mean setting up the system after a clean flash. y'know installing all the apps etc.
i offline charged the new battery to 95% and the images show the remaining amount.

this looks like it's totally fixed omg
The reboot with drop should be because of reboot after installing apps (generating dalvik etc), right?

actually, no it was after i installed all the apps i then installed adaway & xprivacy— and both need a reboot.
as i said, i first topped the battery till ~95% by offline charging. plugged out the USB cable. booted into recovery, wiped and flashed. then booted into clean slimkat and start using it. all on battery power! :laugh:

This is actually awesome! , when I'll get my new original battery I'll let you know if this fixed my device too :fingers-crossed:
I totally forgot how much amazing this device's battery was before this problem
alright you got me!
I've tried everything! flashing stock,pit,cm10.2, cm11 newer revision, deleting batterystats.bin and dockbatterystats.bin. reloading several times, but only got depressions.
Maybe there was a strange bug during the first flash progress, which destroyed the battery ?
Because we flashed all the same CM11 based version, and it killed the batteries, which was running excellent before :/
i'll order a new one now =) did you buy the original one? or another with more mA ?

original one...and after the second charge it holds on standby quite nicely
I finally made it to get the original Samsung battery for Christmas from Amazon
This is my partial usage with a reboot at 65%
After the reboot it got to 66%
This is great, so it definitely was the old bad battery
