Try to completely empty the battery by rebooting after your phone shuts down because of low battery. Keep rebooting it after it shuts down again till it doesn't want to boot anymore. Till the battery is completely empty.
Then Charge it again and leave it on the charger for more then 20 hours.
Don't know if it's gonna work but give it a try
EDIT: Q? are you using a custom ROM ??

Ok I'll give it a try, thank you. I have this problem since i flashed a modaco firmware and wiped my battery cache via cwm. Anyone else having those issues?

I reverted back to stock on my O2X and I can get 48 hours out of the battery. I had the same issue as you and reverting back to stock seemed to cure it too.
Just an FYI I thought I'd share.

48hours when you are using him or 48h max on standby

USE phone heavily. Use it till the system turns OFF automatically
Turn OFF phone
Charge till it says it is FULL
Start phone in RECOVERY Mode
Select Advanced CWM Features
Select Wipe Battery Stats
RESTART phone

Sorry, should have given more detail. That 48 hours is with general browsing and social networking with a fair bit of video recording and camera use. No 3G though. All data was over WiFi.
Certainly not just stand-by though.

No full power use of the processor i understand

i thought i had the problem too with the MDC fear 5.3 but it just jumped from 98% to 100 after 10 minutes so its probably a mistake which solved itselve if you charge it long enough.

Didn't work for me, i did it exactly this way, charged it for about 10 hours, booted in recovery, wiped the battery stats and it stills shows 97% when i boot it. However, it's not a disastrous failure, i can live with it and hopefully it gets fixed sometime.

Finally, i found the solution for me. After i reflashed the stock rom, where this problem doesn't occur, i flashed a modaco rom again WITHOUT WIPING THE BATTERY STATS. Now it's all working fine, i charged my phone to 100% a few minutes ago. Hope it will help some of the people, who are still having problems.

Does kernel version has anything to do with this issue?

Don't think so, i tried the stock, Paul's kernel from FR12 and the EternityProject Kernels 1.3 and 1.4, it was all the same until i tried reflashing without wiping battery stats. For the record, i flashed the new TK-Rom V 0.6 with the EternityProject Kernel 1.4.

battery stats is wrong...

my XZ died at 20% (jump straight to 0% and auto switched off ), so I think the phone mis-measured the real battery level.
since there is no wipe battery stats option in cwm anymore, how do I fix this issue?
thanks

We're all facing this problem, the only solution I see is to completely drain the phone and then completely charge it before turning the phone back on.

oh is this a general problem with the new. 423 firmware?
thanks

Just to correct a misconception on battery stats. The option to wipe the batterystats.bin file was removed from newer versions of CWM (and TWRP) because it does precisely nothing that is useful.
That file is deleted and recreated every time your phone is fully charged and has no effect on the percentage of battery shown to you.

tried it, and i think this method is working!
my phone battery dropped to 13% and was still on, warning message also pop up at 15% as usual.
P.S. i charged it again at 13% coz i needed to use it, will test it later

[Q] Mediaserver taking between 60-80% of Battery

Hoping someone here can help me with an issue I keep having with my phone and no matter what I try, I cannot seem to solve this issue.
Last night, about 1am I went to bed, Phone was at 100% charge. This morning when I woke up, the phone was down to 58%. According to the power in settings, this is what has used the battery overnight.
Mediaserver 84%
Wifi 5%
Cell Standby 3%
Phone Idle 2%
Android OS 2%
Android System 2%
Screen 1%
Onavo Count 1%
I havent got an SD card in the phone and havent for over a week because I thought that might be the problem as others have said on here and I have next to no apps installed also so I cant figure out what is doing this
Im on android 4.1.2 and phone is not rooted. No further updates are available for me yet either over the air or connected to the PC via Sony companion software.
Anyone got any ideas what might be causing this?

Did you leave your earphones plugged in?

Even though it's only been a day I'm getting the same problems with my ZR too
Sent from my C5503 using xda app-developers app

Ive not left my earphones in no and yesterday as a last resort I did a factory reset on the phone and Ive put no songs or hardly any apps on the phone and its still doing the same thing. Again, media server over night was responsible for over 50% of battery drain, this is 12 hours after a factory reset.
I give up with this phone now, it seems to spend more time plugged in on charge than being used

verwhri Rail
do you have lots of images on the phone? i used to have a similar problem with my s3. after i start up my phone i will let it sit for a while before i clear all my running applications. sometimes i do it before i hit the bed too. seems to help. not sure about XZ since i have not encountered such problem yet.

Its a completely clean factory reset from yesterday, so there are no images at all taken with the camera or stored, and no music/mp3s stored on the phone and no SD card attached either

just to double check, you are already on 4.2.2 right? I remember quite a number of people on 4.1.2 experience this problem (including me). most reported the problem was gone after updating to 4.2.2. i didnt get to try it myself as I sold my s3 even before 4.2.2 is officially out

No im still on 4.1.2. Thats the latest version available to me over the air or via PC companion (am in the UK) and am not sure I trust myself or if its easy to upgrade to the latest version any other ways

It's quite easy to fix though.
Just go to sound settings, and school down to the bottom. Disable all the checkboxes that are enabled.
That should get rid of that media thing in your battery stats

Wait for the second charge and check the mediaserver again.
If you upload and download videos or photos in whatsapp can cause this.
Download wakelock detector from playstore and post some screenshots.

Thanks for this, ill try it out now.

Well, it was almost back at 100% charge anyway so i installed wakelock detector, and did a reset. Once switched on, i let it time out and left it for two hours.
Just had a look now in the wakelock app and I have something which says:
AudioOut_3 - 2 hours 8 minutes x1 - thats pretty much the entire time my phone has been asleep. So i assume something is stopping my phone from properly sleeping. Plus in those two hours, my phone dropped from 100% down to 88% (Mediaserver responsible for 91% of the drain)
I have all phone sounds and vibrations off for keypresses and notifications etc.

All you can do is repairing your phone with sus or flash your phone with another firmware and try again.

Well, i upgraded to 4.2.2 yesterday, completely fresh install and charged my phone back to 100% again. Overnight, over 8 hours, phone again drops over 30% of the total battery, again, in the battery stats, nearly all due to media server. I got no idea what to do now

Ive not got any games installed on the phone at the minute and on the actual homescreen all i have is the google search bar and the weather app. Nothing else on there apart from the settings shortcut. Ive tried to be minimal in everything to try and track down what the issue is.
There is no music on the phone, no SD card installed and the phone is totally silent, no sounds, vibrations, nothing.
The culprit it seems again though, according to the wakelock app, is something called Audioout_3. Which has kept my phone awake for pretty much the entire night. but ive no idea what this is relating to

Maybe a faulty phone,send it back if you still have guaranty.

I'm having the same issue, like most threads I've searched for; I tried checking for any corrupt mp3s, pictures etc. I did multiple factory resets, Flashed CM10, Flashed Carbon ROM, even Stock ROM was useless. It's really beginning to frustrate me, doesn't anyone have a fix to this? Mediaserver battery drain threads have been going on since June 2012 or even before that!

Xperia V - Huge battery drain (Google Services)

My Xperia V was draining much battery while sleeping, so yesterday I flashed cm-10.1.3-RC2 hoping it could get better.
But it's still draining almost 30% in a period of 8 hours, while I'm sleeping.
I can notice a huge drain caused by Google Services and have already greenified some apps.
It can't be normal, right?! Could someone help me?
Despite this problem, now I have a really better smartphone... So, thank FXP and, please, keep supporting Xperia V. :thumbup:

Not sure if this question belongs to be an own thread...but ok. here we go.
from my experience with Cm i can tell you, if you want better battery life, then you maybe should use a stock firmware!
I used CM and AOKP some weeks before, but the battery drain wasnt normal, not to say horrible.
But this is my experience. You should ask in your CM-Rom Thread, or CM Q/A Thread i think.

I'm a new member and I couldn't ask this in CM thread
I understood what you've said, but even using stock rom I was having that percentage of draining at night...
Do you have a Xperia V?
Could you (or someone else) tell me how much draining is considered normal in the period I've mentioned before?
Sent from my GT-I9300 using xda app-developers app

30% in 8 hours means that on average your battery will last a day.
That is perfectly normal.
Also, if you keep flashing stuff and installing apps then it drains battery quicker. Leave it alone for a week and see if it settles down.

Sorry, i have a Xperia T.
in the xperia T thread of tilals unofficial CM build (development section) someone mentions also such problems:

So, i guess its normal? But an actual CM User can give you better report. Not using it anymore.
awww, gregbradley?
30% in 8hours sleeping? horrible....but you are right, let it settle, fmlogin

Omg, my Galaxy s3 loses only 2% in the same period while sleeping, it's a BIG difference
I had been facing this problem since I bought this phone (2 months ago), that's why I tried to flash CM yesterday... So, I think that nothing will change if I just wait...
Anyway, thank you guys...
Sent from my GT-I9300 using xda app-developers app

apologies, I didn't see that it was 8 hours while you were asleep. That is not right. But it may be because its working hard after a flash. Please leave it for a while and it should settle, or install better battery stats app (Free on xda) and see whats keeping the phone awake.
Also check what your cpu is set at and the governor, if its on performance it will be maxing out all the time..

The governor is ondemand and I didn't change the clock of cpu...
I'll install the app and come back with a screenshot, so I think it'll be easier to find some problem

Good to know that this isn't happening only with my phone.
Sent from my GT-I9300 using xda app-developers app

Some screenshots.
The graphs show another problem: it is like the phone just know that lost some battery when I turn on the screen.
For example: if I leave the phone with 95%, it pass the hole night "thinking" it has this value, but when I turn on the screen the battery instantly loses around 15%, this "fast drain" stabilizes when it reaches the "real percentage".
Could it be a hardware problem? The battery itself...
Has already someone noticed something similar?

Xperia Z DEad on battery work on cable. Solution?

Ill try to explain my problem in detail...
I have an unlocked bootloader Xperia Z
I flashed first 4.4 build to try the new kitkat android....
On these build i have incredible battery life but, obviously other kind of stability problem....
Then I reverted back to Monxified 4.2.2 rom, and I make a little mistake (flashing new rom with phone at 40% battery with cable plugged in.....
After this i start experiencing bad battery life and suddently shut down at 30-40% battery level....
I tried various full charge (even with phone shuttend down) and long time charging even after the battery indicator is full......
Nothing changed and situation get worse with phone shutting down at 60%...
After this i tried move to 4.4.2 beanstalk.....
It seems to work a little better but again phone suddently shut down during usage and start to be unable to go after boot logo (before bootanimation)
If I power on phone i see the kernel logo and when boot animation must came in phone simply shut down.....(it doesn't reboot or go in bootloop it shut down and I have to push the power button to see the same crap)
With power cable plugged in phone work without problem, but even after startup if I remove cable phone shut down after 30sec-1 min....
BUT, and this is the strange one...
If I boot in recovery i can do what i want....even withoud external power in recovery i can use phone for 30 minutes adn over without shutdown...i can flash rom and other stuff and my Xperia Z doesn't turn off....
I'ave also tried to flash a completely stock FTF with sony official kernel (4.2.2 and 4.3 versions) but nothing chage....
Leaving aside recovery...every rom i flash simply can't go after kernel logo without external power
,

I often flash new roms with cable plugged in... So, you have already done a full wipe, so try to use the battery calibration app, maybe the battery stats are corrupted.

Indeed. The option to delete batterystats.bin was removed from most custom recoveries long ago as it does nothing.
