Iphone Will Not Charge To 100. Optimized Battery Charging is on by default when you set up your iPhone or after updating to iOS 13 or later. In most cases if you charge a battery fully 500 times the difference in performance will be very noticeable.
How to fix an iPhone battery not charging over 80. Thats every single day all the way up to 100 no matter how much battery power is left. You could make an appointment at an Apple store just to be sure but Im 99 sure thats it.
But deep discharges also negatively affect the battery which is where low power mode comes in.

Yes and no the iPhone kind of stops charging when it reaches 100. My last 2 iphones 5 and 6 both had the battery shit out on me about half way through the 2 year cycle.
