Overheating and Drain Battery

[ShinoAmakusa]

I updated my Xperia XA two weeks ago, and the phone worked good til' yesterday.

I was charging it and from one moment to another it turned off... I though it was freezed, red LED appear in the top but the phone wasn't doing anything, I tried to restart it, keep volume up+ power on/off but nothing... I removed the back and un-plug the battery, after a few tries it turned on again... And the troubles begined... I charged it but from 92% after 10 minutes was 85% discharging with anything... and the phoned gets so warm, I can't connect it to charge cause it don't do anything, just turned off, and can't use it because gets so warm in the top. What can it be? Help! 

Edit: If I charge it without the battery, still warms up

Well, thanks for replys. I took it to the technician and the problem: A microchip was fused, and made the cell, in addition to putting it very hot, discharged the cell very fast, despite the load being good. 

They repair it, and now it's fine. Thanks @CameronT
