[Xpert2]

My Xperia get turn off (dylisplay just became Black) 2 minutes after unplugging from charger. When i trend to turn on, phone doesn't react for about few minutes. is it possible that phone get overheated?? - because he was Hot but nothing New..
Phone is great, i love it but i'am starting to doubt in SONY quality!

try to let the phone cool down first,

the connect it again to the charger (using wallmount adapter)

press power button and voulme up button at the same time and hold them for about 5 seconds
see if it works

use the search bar above and look for "battery drain"

software repair using Xperia Companion

a recently chrage battery will drain a bit quicker as it re calibrates itself right
