Battery Overheating!!

[TeamLTG]

Hello,

 

I recently rooted my Xperia z2 using kingroot. Since then the battery gets really hot, it has gone up to 45 Celsius. Also, the top left coner of the back panel I can press down, this is probably because the heat may melt the glue in the back. I don't have a Sony store in my country so I can't go to repair it.

How can I fix the Overheating and is my phone still Waterproof?

 

Also the cpu stays at around 45 Celsius 

 

P.S: I have a locked bootloader and battery life is very good.

is it expanding it at all? if so, you will have to replace the battery. if you don't it will die.

What do you mean by expanding?

No its not, just the top left side can be pressed down a little (1mm)
