Apple has updated its battery health settings in iOS 18 in iPhone 15 by giving more control to users over charging limits.
The new iOS 18 adds more options for a hard charging limit
As introduced in 2023 with iOS 17, the Charging section of Settings on iPhone let users turn on a limit to how much a battery will be charged. The optional limit was 80%, and it meant that in order to extend the lifetime of the battery, it would never charge beyond that limit.
Now in iOS 18, the same setting comes with a range of optional limits. Specifically, users can now set a charge limit of 80%, 85%, 90%, 95%, or 100%.
