Xperia p battery draining very fast :( . Please help

[Jeno_Jodi]

I am using xperia p .

Model: Sony Xperia P LT22i

Rom:6.2.A.0.400 (Jelly Bean)

Kernel:3.0.8+

I have to charge it three times a  day without even any significant use! Battery drains by 10% an hour with the stamina mode on when i am not even using the phone (data, bluetooth, wifi etc being turned off). Tried factory resetting 5 or 6 times and using apps like better bettery states to find the draining apps (Tried uninstalling all the 3rd party apps). No apps other than other than some system apps (like kworker 5,7 etc) seemed to be draining the battery while in deep sleep. Can anyone help? At least tell me that wheather it's a problem of the rom or the battery? I am using this phone for 6 or 7 months and charged it with a samsung charger 3 times. Can it be a reason for such heavy battery drain? I have upgraded to JB like 1 month ago and this '10% an hour' thing started quite recently (2 weeks after the update). ICS battery life was poor too, but not this much (had to charge once or twice a day with low or less than moderate use). Please help! Is spare battery for this phone available?

You say you factory reseted,but have your repaired thephone with PCC or SUS?I think you should also use only Xperia charger for max performance.

My Xperia P ICS battery life was great, and after updating to Jelly Bean I reset my phone and my battery was draining very quickly I was losing so much battery overnight even with Wi-Fi and Mobile Data off. I went looking for ways to increase battery life and here's what I came up with:

-Turn off Wi-Fi & Mobile Data when not in use. (Or let STAMINA Mode do that for you)

-Go to your display set-up and put your Brightness to Adapt to lighting conditions and put it on   power- save mode for optimal battery life

-The Stock weather widget also takes part in killing the battery so disable it. (Settings>Apps>All>WeatherWidget>Disable)

-Turn off Sync for accounts that is not needed.

-Don't install Task Killers that always run in the background and waste battery.

(Get ES Task Manager)

Now these are the main reason why Xperia P Jelly Bean battery drains so fast.

Phone app always runs in background so "Force Stop" it. (You will still recieve calls and stuff) (Settings>Apps>All>Phone>Force Stop)

Another reason to bad battery life is that your Network Mode is probably set to WCDMA/GSM you should change it to "GSM only" for better battery stats. (Settings>Wireless&Networks>More>MobileNetworks>NetworkMode)

After doing all this restart your phone and it should be doing fine.
