unexplained battery drain

Hello

I had two s 3 minis and one was working properly and on the other the battery uncharged really fast .
Then i broke the screen on the good one and decided to change only the touch screen from the one with the battery problem to the good one. I changed only the screen and the battery and the mainboard remained .
But i have the same problems on this one now.
Can someone help me ? Is it possible the probleme is the touch screen , bacause the battery uncharges even if the screen is turned of an he phone is on stand by.

Thanx for the answers

Welcome to the forums.☺

What do your battery usage stats show to be the main users of battery charge?

Re: unexplained battery drain

I have the same problem with a new s4 mini. I run battery doctor to close out all apps, and leave the phone in standby for 6 hours - and the battery goes from 100% to 10%. I looked at what the phone was telling was burning the battery, and it's all ANDROID SYSTEM. I've no idea what it is within Android that is killing the battery though.
