Two days ago I bought my new phone xperia sp but i've notced that overnight it's battery has drained from 100% to 80% and also during normal usage like texting it looses it's battery real quick. Even i've disabled bluetooth, wi-fi, hotspot, GPS and enabled stamina mode but still it keeps loosing battery at a high rate. I would also like to mention that sometimes like when i touch the screen lightly, the toch dosen't respond, especially while touching the home and back button and then I touch it with a little more force then it works. Why is it so? It's irritating. Does it have something to do with Glove mode "On"? I would appreciate some help and suggestions. Thank You.
*It's Xperia Sp not xperia P* i'm sorry
I moved your topic to the right section.I suggest you force restart your phone(power button+vol up until the phone vibrates).After that,uninstall any taskkillers,free ram apps,battery savers.The SP is known to have some touchscreen issues,especially when the phone is on a horizontal surface.
I have the same problems as you.
Battery drain is very annoying and 100% NOT caused by an app. The phone has nothing installed and is exactly like it comes brand new.
The only thing I've found that helps is to uninstall google+ and then it drains much much slower. But it comes back if I update any app on play store.
It is either a bug with android 4.1.2 or sony's firmware.
just talking about tonight, before going to bed my phone's battery level was 100% and now when i woke up it's down to 80%. I mean what the 20% battery drain overnight.
i know it's stupid but i just can't force restart my phone. I held the power button and volume up button together for about 20 seconds but nothing happened, no vibrations and nothing. But yes I did uninstall task killer app
Mine drains the same as yours, about 20% overnight with phone doing nothing.
You cant restart SP with volume+power button. You need to remove back cover, there is a little yellow button.
I am using 2g only and still drains fast.
No apps are showing usage, its like battery is magically disappearing. 
same here spixel even i use 2G instead of 3G but still it's the same case! 2370 mAh battery is supposed to last long. I guess it's the recent firmware update that sony has launched for SP
hey! you should just factory reset it again. I tried it and battery has shown some improvement. i just took it to the care center. they backed up the data and contacts then factory reset it.
