Battery drain after screen replacement.

Hi All,

I got a cracked screen on my iPhone 6, the first replacement that i got didn't work at all, but when i reconnected the original again, it worked again.

So I returned the screen and got a replacement. Now I installed this one, it works fine, also all other functions of the phone work, accept for the touch ID and the battery drains by the minute..... Any suggestions?

---Update---

Apparently the battery drains only when the screen is in use, if i dont use the phone the battery usage seems normal...........

Bad screen assembly again?

I disconnected the screen and checked all connectors with a magnifying glass and they look ok to me, no shorts or damage. I also left the home button flex disconnected since i damaged the flex, but it still drains the battery when the screen is in use.....
