iPhone 7 battery
Recently my iPhone 7, which is about 2 years old, keeps dying randomly and the percentage drains quite quickly. It’ll die when it’s still got 80% battery left, 40% battery left, 20% battery left and most recently it’s been dying either as soon as I unplug it at 100% or while it is charging. I’ve tried restarting it but that doesn’t seem to be helping at all. Any idea what could be causing this and if there’s anything I could do to fix it?
iPhone 7, iOS 12
