Calibrate iPhone battery - how it works
You should calibrate your iPhone's battery from time to time - especially if the percentage of the battery shows jumps. In this practical tip we explain how to calibrate the battery correctly.
Empty iPhone battery for calibration
Apple recommends performing a full charge cycle to calibrate your iPhone battery.
- Use your iPhone until the cell phone switches itself off because the battery is empty. You do not have to worry about the battery being damaged by deep discharge, as the iPhone switches off in good time before it is damaged.
- Hang your iPhone on the charging cable and let the battery charge fully, ideally without using the cell phone. When the charge indicator shows 100%, you should let your iPhone continue to charge for at least 15 minutes.
- You should repeat this process every few months to ensure the best possible battery performance.
