[Q] Extreme battery drain

Hi guys,
i recently bought a LGOS and soon began to tinker and try out custom roms. and right now im running into a problem i couldnt solve by searching through this or other forums. i tried out several different roms with different kernels (modaco, swiftextreme, stock (froyo and gb), cm7 newest nightly) and with every rom my battery drainage is way higher than it should be.
with battery monitor im reading values between 100mA and 900mA when the phone is in standby mode and not being used! the temparature is also quite high ... round 38°C
on some forum i came across the problem with FD dormancy, and because my provider ( eplus) doesnt support fd dormancy i tried using a workaround by shutting down the phone application everytime the mobile data connection is being disabled... but it didnt help.
so i tried wether or not my problem is related to an app or service. i shutted down every process possible and the problem still persisted. i also tried disabling go launcher and using the stock one, but it didnt work.... im using no widget at all on my desktop right now
i tried wiping my battery stats through clockworkmod recovery. and it didnt help.
right now im beginning to believe that this problem is hardware related. im so frustrated with this :<. the phone itself is awesome, but this problem makes it quite hard to love it :<
thanks for your help

update: for the most part the problem was related to bad battery calibration. now the battery consumption is "only" ~50 mA in standby mode... the phone i had before, a "htc hd2 with newest hyperdroid rom" only consumed 3-5 mA when sleeping. when playing 3d games like gameloft's "order and chaos online" battery consumption on my LGOS averaged round 20% in 30 minutes of playing ... is this value normal?
the situation is still not very satisfying :<

Update: i noticed that the battery voltage stats are totally weird. The battery monitor values seem to jump from low to high values while discharging. I also stumbled across some thread regarding cm7 from April. The battery driver from LG seems to be faulty. Is there any fix ffor this... I'm using modaco right now

another update in this conversation with myself :
i tried using cm7 ... and it actually made my problem even worse. the phone discharged in less than 5 hours while in standby. now im back to modaco... discharge rate while in standby is ~40mA.
is there anybody else on here who can help me ? :<
i guess i will need to sell this phone :<

sounds like a hardware problem, maybe you should send it in for a repair.
anyways when using the phone it normal that the battery is empty after 5 hours or so... but that should not happen in standby. does it happen with a clen install an withoit anything installed?

thanks for your reply ... my father just also bought an optimus 2x... so i will do some comparisons to check what exactly the problem is and wether or not it is software related. my last step before sending it in will be to revert back to stock froyo and install no app at all and check if the problem still exists ...
damn this phone is costing me many hours of stress and work ^^

Battery virtually dropping, hardware or software problem?

Hello,
for months it has been happening that when the battery usually reaches 25% (but not always sometimes even 40ish) the battery indicator drops to 19% and it could either remain stuck at that value until the charge actually drops below 19% and continue the usual drop or it will rapidly drop to lower values in big steps like (19->10->4) in minutes to finally actually automatically power off. The strange thing is that it's all fake! When I power the phone again the % will go back to where it should be before this virtual drop happened and continue its usual drop, it always worked until today when for the first time it continued the "game" non-stop until the battery ended the actual charge (for hours)! You have to consider that i was in a place in the mountains where the gsm coverage was very low/non existent so it could be connected. But it got me worried because it couldn't control it!
Apart from a solution I'm asking also what the reason could be. It could seem like a battery problem but why would the phone actually recognize the actual charge after it powers off and I restart it ? Seems like a software problem (battery driver maybe?). But I wouldn't exclude that it could be the battery maybe when the charge gets low the voltage drops dramatically under stress to a point where the phone thinks its almost empty.
I'm using cm7.2 kang 119 with standard kernel.

Have you tried wiping the battery stats..?

So you say it's done that for a while... obviously it's not possible to pinpoint an app. I guess then you have some funky cruft buildup (say, a lot of rom flashes and some settings getting squiffy) or your battery's dying. I know for sure that the rather excellent Battery Widget Reborn can give a health check on the battery as part of the widget (although I dunno if it's GB compatible). The second solution may be to try a clean wipe. It's drastic, yes, but can clean up any lingering problems if you've been updating for a long time without the occasional wipe. If you haven't...then I dunno.

Baaaaaad advice. That's just a placebo and doesn't do anything. So please don't recommend it.

What do you mean by this? Don't be rude, just help out if you can.
OP: is it possible you update the rom/kernel?

The thing is it doesn't happen at every single charge! That's confusing! Maybe I'll try to update to #135 and install symbiosis kernel and see.

I'm not trying to be rude. It's just that battery stats are reset after every reboot, so wiping them does nothing. It's also easier to be blunt to get a message across.

I have similar problems...
Mine force closes 1 out of 7 charges at a random percentage...today it was at 53%...it shows cc% but in reality the battery is drained out...I am not sure what is the problem...this showed up after I inhaled wiui 2.5.25, other than that I have minor issues with this rom...I really like it...only if I could make the radio work...

Bb=725 ril=0218(10b) the kernel is the latest OC kernel from temasek (any suggestions there, is there a better one for wiui/miui roms?).
I'll do a battery wipe after a full charge and see what happens next...

shut down problem with Note

Hi everyone, i have a problem with my Note, i am not very good with English i hope you will forgive me if i make any mistakes
When i play games, use application, use wifi or something like that my screen flickers and the phone shut down. If i try to open it again it warns me that i dont have battery, appears that i have 1% battery and close again although i have more than 70%. After 10-15 minutes i open it and shows battery 70%. If i talk there is no problem, i can use the phone but what ever else i will do it shut down.
My phone is not rooted, i have used factory settings but no result, i have also removed the micro sd card and still the same.
Can anyone help me with my problem?
Thanks in advance

I mean if i had a problem with battery shouldnt i have a problem and after 10-15 minutes that i open my phone again?
It is ok after, shows the life nattery i had before the shut down and if i use it just for calls i dont have any problems

usually when a battery is faulty, the phone cannot survive a photo capture with flash on. .. the symptoms that you said also indicates a poor battery,

[Q] [SUPPORT][BATTERY]Battery drain or Software problem?

I own a Samsung galaxy S advance for the past two years now.
Still on Gingerbread 2.3.6. India unrooted. Past 3 weeks I was visiting USA.
I was using a AT&T Go-phone there.
What happened is my phone always switched off while I was using it. Just like THAT! I was thinking because I was using WhatsApp on this phone, I thought maybe cause I have a different number for WA and so WA was continuously trying to identify the number whenever I was on-line.
Specifically, the battery used to drain from 75 or 63 or 47 % right down to 4 %!!!. And when plugged in, in off state, the battery used to get charged to full within seconds (the indicator showed full 100%). After I switched it on, the phone again switched off. This happened quiet a few times and so when I returned to India, I uninstalled WA reset my phone, formatted the USB storage and used a few apps to recalibrate and determine the "health" of the battery. Also I noted the time for it to switch off. I was around 2 and a Half hours which means actually the battery drain and switching off randomly continued even after factory reset.
Now here are the questions
1)Has the battery gone beyond its life or is there a problem with the software or is there some bug that is killing the battery? Just a small note here, the battery is kinda swollen
2)Also, what should I do, buy a new battery or install new software (custom ROM or something else) depending upon the ROOT cause from the above question.
Please help.
Thanks indeed.
God Bless

Seems like a battery problem. I read that it has about 500 charge cycle. And 2 yearsh has more than 500 days...

Thanks for the prompt reply,
Yesterday, I charged the battery (phone) and I didnt install WhatsApp. I left the phone in flight mode and just let it out for "idling".
For a good 7 hrs it was as it is and then I installed WA and bang! switched off.
Do you reckon that, the application uses a lot of juice so much so that the remaining battery dies off instantly? (now that the battery is in bad "health")

Indicator probably shows non correct value. Or it shows, but battery is so weak now that little consumption of energy drains it that much...

Lollipop touch and hold quick settings?

The quick settings aren't behaving the same way as aosp, with touch and hold disabled and tapping only toggling the setting.
Even the the mobile data toggle won't open up the data usage counter in the settings page but only toggles on and off. Anyone else reporting the same?
C6902, US stock. 242 ftf flashed in the morning, unrooted.

Also, facebook for xperia has removed contact sync. Is this just me? Phone also heats up pretty quickly on usage...

did you use your phone after the update? it's normally heated up. Settle it first for 5 mins or more until it cooled down.
Regarding with the battery life, from last night after the update, my battery life is at 24% and im using it right now while listening to music. with couple of games like 30min + Clash of Clans and web browsing, i dont find any issues regarding with the battery.

You can just uncheck wipe data It's always a good idea to clean flash an OS update. Oh well.
No idea about contact sync? The overheating settled, but I'll have to see. Overall, really good work from Sony. No Location based Wifi, but apparently they made changes to scanning that makes location based wifi defunct, lol. I only wish the long press on toggles worked as well, but they seem to have removed it everywhere, so no complaints I guess. Camera frame rate has suffered in the new firmware though, not as smooth as it used to be.
That's weird, my status bar and battery stats are always blue. Are they supposed to be different for everyone? Even in whatsapp my status bar is blue...
