Apple is introducing a new feature for iPhone users that allows them to limit their phone’s charging to 80% to help preserve battery health. Charging the battery from 0% to 80% is more efficient and produces less heat compared to charging it to 100%.
This feature aims to prevent overheating and extend the battery’s lifespan. However, experts suggest sticking with the Optimized Battery Charging feature instead, as limiting charging to 80% offers only minor benefits and may limit the phone’s full battery capacity.
Ultimately, all batteries will degrade over time and require replacement.
