Lithium-ion battery is a sensitive element, so it must be handled carefully during manufacture and maintenance. Don't try to replace the iPhone battery yourself. Untrained technicians may not follow the correct safety and maintenance procedures when replacing batteries, and may lead to incorrect replacement or maintenance. This may also damage the battery, resulting in overheating of the battery or personal injury.
If this prompt appears on your iPhone without any maintenance, you can try to return it or contact Apple Support for more help.
Users using iPhone XR, iPhone XS series and newer models should be cautious when choosing to replace the battery. If this prompt appears after unofficial disassembly and maintenance, Apple's official after-sales or authorized repairer may refuse to repair your equipment.
