Only technicians with the knowledge, experience, and tools required to repair electronic devices should replace a battery.
iPhone 12 Pro Battery Safety Warning How to handle a battery thermal event A battery thermal event is a rapid chemical chain reaction that occurs inside a battery cell. The energy stored in the battery is released suddenly, which can cause outgassing and fire. A battery thermal event can be triggered by physical damage to the battery, improper replacement or repair, or temperatures outside the battery’s operating range.
iPhone 12 Pro Battery Safety How to handle batteries Warning Fully discharge the battery before you begin a repair. A discharged battery is less susceptible to a battery thermal event. If you can’t determine the battery level, don’t repair the device. Perform the following steps to discharge the battery: • Disconnect all external cables. • Turn on the flashlight from the Lock Screen, in Control Center, or by asking Siri. Wait until the device has turned off and the flashlight is no longer illuminated.
