When encountering battery issues, we often choose aftermarket batteries for iPhones to achieve better cost-effectiveness. However, after replacing the battery, users may encounter an error message starting from the iPhone XS series, indicating that the replaced battery is not an original iPhone battery. Additionally, the battery health data differs from that of the original battery. To address this situation, we require a repair programmer to restore the data. However, for iPhone 11-13 series, in addition to the programmer, we also need a tag-on flex.
