battery health dropped from 100 to service in one day
i bought an iphone x with 100 percent battery health and after few weeks of use it was 100% and all of a sudden it went to service so please help tell me the fix to that
iPhone X, iOS 14
iPhone X was released 4 years ago now. A 100% Battery Health reading on what I imagine was a used device was likely a calibration error.
Schedule an appointment at your Apple Store Genius Bar for evaluation and options would be what you need to. A new battery will cost you $69. Do NOT get the battery replaced by a 3rd party. It will not be authentic and Battery Health will not work with an aftermarket battery.
