Theproblem began after installing lollipop with getting high temperature when charging
Then high temperature when mobile data is on
Then the phone powered off at 50% battery level.
Now the battery drains and I can not power the phone on without connecting charger.
When unplugged the phone power off immediately
I repaired the lollipop with Sony companion app on pc but in vain.
I downgraded to kitkat 4.4.4 it seemed good at start but it turned worst.
I have the original charger.
Now, I want aserious solution for that fatal problem.
