Currently, the latest system IOS17.4 version cannot clear the historical health data of the phone through the battery pop-up window, therefore, the battery health data on the mobile phone cannot be modified with battery repair FPC or adaptor or device, it is necessary to flash through connection with battery repair FPC or quick repair board-Q1 in order to modify battery health of mobile phone, flashing software like ShaLou, i4, 3uTools etc. can make it (Cautions: please upgrade the flashing software to the latest version).
