Answer to "6s replacement Battery shows "Battery Service" on ios 11.3 Beta"Hi there, I replace my battery in my iPhone 7 plus and since then it also shows service. I fould some forum tread where someone mention that the phone was stared accidentally before all cables were connected. The fix for this seems to be: to remove the battery connector once again and put it back. I tried that, but with no success. Does anyone have any idea how to fix this service issue ??
