Iphone 5s.Have the same issue after battery replacement, find a temporary solution.

when Disconnected Home button flex cable from logic board, battery drain stopped.

Tried many different home buttons but when connected battery draining started again.


Actually I also changed home button and charing socket nothing changed. The phone still draining battery while on standby except home button flex cable departed from the socket.

Couldn't find different solution

Any idea what the problem is?
