iPhone 6 battery drain after screen replacement

Hi,

I have recently got a customers phone that needed a screen replacement because it had a cracked screen. I have done this many times, however, this time the screen I ordered had white lines coming down from it. I thought it was a faulty screen and sent it back and bought a new one. The new one works perfectly but the battery suddenly drains every quickly. I have done a few tests but I can't figure out what is wrong. I would be very greatfull if someone can help me out here.

Observations:

  • Checked anohter screen, still draining
  • Found out that phone has lots of heat at shield below connectors
  • Looked under microscope and not damage to connectors or filters
  • Even when screen unplugged phone drains battery and is warm
Answer this question I have this problem too

Is this a good question?

It could be caused by faulty software (iOS 11.0.0-11.0.3 have major battery bugs) or maybe the battery was damaged during the screen replacement,

I have used a fully working iphone 6 and put the motherboard from the draining iphone 6 and I can confirm that it's still draining battery so it must be a motherboard problem. The phone has not been updtated to IOS 11

The phone is on IOS 10 so it hasn't been updated. It's a motherboard problem because I have put it in a working iphone 6 but just swapped the motherboard and it's still draining the battery.
