All iPhone and iPhone 15 Pro models offer a new battery health setting that, when enabled, prevents the phone from exceeding 80% charge.80% limit!
The new setting is different from the Optimized Battery Charging feature, which prevents the iPhone from being constantly charged at 100% by learning the user’s daily charging routine. The new option, which can be accessed on all iPhone 15 models under Settings – Battery – Battery Health and Charging – Charging Optimization, allows the iPhone to charge up to 80%; After this point, the phone stops charging completely.
The user is given the option to limit or turn off Optimized Battery Charging or 80% to preserve the iPhone’s battery health. Users generally prefer to charge their devices between 40% and 80% to extend battery health. Users generally avoid charging to 100% since more energy is required and more heat is produced in the 20% after 80%.
