Battery drain solved

Hello, and scuse me for my poor English but if that can help someone:
I had a lot of problems with battery drain of my phone, so i've tested some roms but give me bad results. All my tests was the night, with no data, no wifi, no bluetooth
Supreme Rom was the first and battery drain was 3% by hour
Rom Ripper V1.0 was the second and with perseus kernel 4 or 5% by hour....!
The third XTrem rom V3 with Perseus Kernel 3% by hour and with Stock Kernel 1,5% by hour. V4, it was the same. I've tested with set CPU at minimum (400 MHZ max) screen off, voltages for all frequences -25mV, don't change anything.
BUT last Night I've tested Padorium ROM V6 with Stock Kernel and OUahhh, my battery was at 90% before sleep and 8 hours after, 87%. So 0.5% only by hour!! And in use (datas or wifi on, internnet, fcbk.....) 1% every 10 min. It's very good.
If that can help someone who's flashing again and again for battery drain....

I would not say this has solved battery drain.
I can get same amount of loss overnight if I turn off data, wifi, bluetooth etc as in 3% all night even less if I put the phone into flight mode. No matter what phone or rom I have used I can get these same results.
For you to lose soo much battery overnight you must have some rogue app running in the background to cause it, that is why personally I restart the phone before going to bed to kill any unknown apps in the background that are going to drain battery.

I don't think there was some apps who drained my battery. I've installed some tasks killers and that don't change anything. I saw regulary apps who runing, there were no apps stranges. I use the same apps now and battery drain is ok.

Whats your brightness at? If screen is eating up all your battery, most probably it is too high

I put it in the minimum. Im kinda paranoid that my phone has hardware issue but the phone is working fine. Im still finding solution why im having this prob. Still not losing hope. Lols.

if you've tried goldenkernel v2? then setting the hotplug and battery saver mode on, hopefully this can help you, especially if you use benzrom v6

Recalibrate your battery. Thats what helped me. my device can last 9 hours and still remain 70% battery with normal usage.
Heres how i callibrate.
1) download battery callibration in market.
2) charge the device till 100% (Dont plug it out)
3) power off the phone. I dont know if this will work on ur phone but i get 0% again. So charge it fully again.
4) once it shows 100% , unplug and plug it in again and wait till it reaches 100%. Do it for 4-5 times then reboot.
5) when your phone boots up, it wont be fully charged, so leave it charged till the battery full indicator shows up. Unplug and plug it in to charge again. Keep doing it for 10 times and the battery full indicator will pop up even quickier then the first time.
6) once u done it, open battery callibration and click callibrate.
7) after that, unplug your device and use it . The battery will last very long.
8) use the battery till 1-5%, u can completely drain it but i didnt do that cause some of my data will be removed after i completely drain my device.
9) charge it up to 100% again but dont use it while charging.
10) after that, enjoy ur battery life

Try using Better Battery Stats (you can get it free from xda) and use your phone normally for a day then see what is draining your battery

Anyone can help me pls?

Xperia Z - fast discharging at around 30% (4.1.2 software .253)

I've got a doubt about battery discharging in my phone. When it normally discharges from 100 to 35% everything is in normal, with similar drops every hour for ex. 2 days. But (even in standby) when battery is on app 35% I see very fast drop to 25-20% in couple mins. At the beggining I thought it is maybe broken cell in battery but I notice that around camera surface is warm, not hot. So it is probably matter of software. What drains my battery so fast and always at app 35-30%? Do you have similar issues? I made factory wipe few charging cycles ago but it did not make any changes.

Do you use any of the power management settings like stamina more or....
What apps do you have installed?
Sent from my C6603 using xda premium

Yes, I always use stamina, I switched it off just before taking picture. I use dropbox, GO backup, Network Singal Info, netmonitor, Gmail and one additional mailbox. I have Google backup - off, Hangouty - logged off, google now - off.

Well, I don't use stamina mode anymore. I too had these sudden drops when stamina mode was on.
Try switching off stamina for a couple of cycles.
If you find that there are no drops, then you have your culprit.

So you mean not use stamina at all or switch it off at around app. 50%?

Try without stamina mode.

Ok, I'll give feedback in few days. Thanks.

Get root access, charge to 100%,delete battery stats(or use battery calibration app),drain battery to 0%,charge again to 100%, now see if still the same problem...

I've tried once without stamina but I got visible faster discharging so now after update to 4.2.2 I am testing with stamina ON.

Deleting battery stats does nothing. I post this every time I see someone recommend it, but I feel that the point needs driving home until people realise that it is a placebo at best.

my opinion
Sorry, it will not improve your battery, just if you have wrong indicated battery %,it maybe solve that. I solved a problem like that.my battery went from 50% down to 18 in a cuple of min.after deleting the stats and a few charges it was O.

No. The batterystats.bin file has no relation to the percentage displayed in the notification bar. It is used to calculate the usage statistics displayed in the battery usage section of settings. Nothing more. The file is deleted every time the battery is fully or nearly fully charged anyway.
The G+ post I linked to was written by an Android framework engineer, so I think they know their stuff

Ok,maybe i'm wrong,but somehow my problem was solved

I am sure that I hadn't wrong percentages but period of strange drain battery (when % suddenly drops) because I felt warm temperature around camera. So I suspect any strange thread/wakelock/trigger.

Battery Problem [Google Services] [beanstalk rom]

Hey everybody, I just downloaded beanstalk rom a few days ago and it is awesome, the only problem I have os Google Services draining 10~20% of my battery, i tried everything on this forum also the GServicesfix app on the market, turned off the location and the sync, no difference. But I guess the problem is not only with Google Services as my battery drains pretty much fast I have to charge mu phone twice a day, Googe Services do drain battery but it is not the only reason, however, it is the only thing with abnormal battery use in power options. ps: I didn't have the google services problem at stock rom but the battery also drained fast.
Any help???? I have 2 problems, Google Services abnormal battery usage and battery drainage disregarding the google services consumption.

Example for battery drainage:
The battery drains about 20% while I sleep at night with absolutely nothing running except WiFi. 20% in about 8 hours.
