Hi, this is Wayne again with a topic “Aftermarket Solutions to Calibrate iPhone Battery Health on iOS 17.4”.
With the release of iOS, 17.4 Apple introduced significant changes to how battery health is displayed on iPhone. The new iOS version also brings in restrictions on battery health calibration, which affects all battery repair solutions available on the market. On iPhone 15 series Battery Health offers a submenu that shows battery health percentage and cycle count in addition to the manufacturing date and date of first use For earlier iPhone models. The battery health display remains unchanged If an iPhone’s battery is replaced and the battery health recalibrated, updating it to iOS 17.4 does not affect anything. The battery health still displays the current capacity of the new battery If an iPhone is already running iOS 17.4 and requires a battery replacement.
