Charging Stops at 80%?

Your iPhone may stop charging at 80% to protect the battery. This can happen if it gets too warm during charging as part of iOS 17's thermal control strategy. Charging will resume once the device cools down. Moving your iPhone to a cooler area may help.

Why Does It Show "Slow Charger"?
