I just got my battery replaced yesterday and have updated to 11.4.1 but i do not get battery health beta percentage. Does it only work with original batteries?
Battery Health in iOS 11 only works with original batteries as the phone cannot really “communicate” with replacement batteries as well as it can with the battery it came with. Also, Battety Health is still in beta and still has a long way to go before it is all polished out. Maybe Battery Health will get better at communicating with replacement batteries, who knows?
