I just replaced the screen and battery on two iPhone 6s. Problem is, when i assembled the phone, the phone had problem determining the battery health and there was a White pressure spot on the screen (just where the metal plate protecting the battery cable, is placed). If i remove the plate completly both the pressure spot and the battery determing problem is gone. So my question is: is the metal plate important or can i keep it removed?
Yeah you should have no problems after you remove it but if you drop it weird it might make the connector unplug but otherwise you should be good
