Apple has rolled out an update to its battery health settings in iOS 18 for the iPhone 15, offering users more control over charging limits to combat battery degradation.
In the latest update, users can now choose from a range of optional charging limits, including 80%, 85%, 90%, 95%, or 100%, building upon the previous 80% limit introduced in iOS 17.
While the 100% limit may seem redundant, users are provided with flexibility in setting their preferred charging threshold. However, the concept of charging limits has been deemed somewhat redundant and potentially confusing, as it only marginally extends battery lifespan while reducing daily charge capacity.
iOS 18’s new charging limit system interacts with the Optimised Battery Charging feature, which halts charging at 80% and resumes just before typical usage times. If a user sets a lower charging limit, the Optimised Battery Charging feature is disabled and can only be reactivated by restoring the limit to 100%.
Furthermore, iOS 18 includes an additional option where users, upon reverting to a 100% limit, are prompted to confirm their decision. They can also choose a temporary 100% limit until the following day, after which the previous limit is reinstated.
While the new charging limit settings offer increased user control, experts suggest sticking with the Optimised Battery Charging feature for optimal battery management. The long-term benefits of adjusting charging limits are minimal, and users may find themselves needing to recharge their devices more frequently during the day.
Ultimately, while the update provides more granular control over charging thresholds, users are advised to weigh the trade-offs carefully and consider their individual usage patterns before adjusting these settings.
