In this video we explain iPhone 17 battery health settings and the difference between Charge Limit and Optimized Battery Charging. You will learn where to find these options in Settings → Battery → Charging, how Charge Limit strictly caps charging at a set percent (80%, 85%, 90% or 100%), and how Optimized Battery Charging delays the final 20% overnight based on your charging routine to reduce battery aging.
