Hello there, I got a dead iPhone 7, so I tested the battery, and the only “weird” thing.. is that the battery is rated 3.8v… and on this one.. im having a reading of 4.1V…. maybe this overpowered issue is preventing the iPhone to turn on???
No, your battery is fine. A fully charged 3.8V battery will typically measure ~4.2V.
