iOS 18 will introduce a feature on iPhone 15 models that recommends users set a specific charging limit based on their recent usage patterns. This innovative approach aims to improve the potential lifespan of the iPhone battery by reducing the amount of time it spends fully charged, a significant concern for smartphone users.
All four iPhone 15 models have a setting that prevents the devices from charging beyond 80% when enabled. iOS 18 expands this feature by adding new charging limit options of 85%, 90%, and 95%. With these new options, iOS 18 now takes a proactive approach to enhancing battery longevity, recommending a specific charging limit to users through a personalized notification.
This allows users to choose the setting that best suits their individual needs. The recommendation also appears in the Settings app under Battery → Charging. The charging limit feature remains exclusive to the iPhone 15 lineup in the initial iOS 18 beta, highlighting Apple's commitment to bringing significant improvements to its newest models.
In a related change, anecdotal reports suggest that iOS 18 might recalibrate the maximum battery capacity percentage of some devices. In Settings → Battery → Battery Health, "Maximum Capacity" measures the battery's capacity relative to when the device was new. A lower capacity can lead to fewer hours of usage between charges, and recalibration could provide users with a more accurate picture of their battery's health. The first beta version of iOS 18 is available to members of the Apple Developer Program, with a public beta to follow in July. After the beta testing phase, the update is expected to be widely released to all users with an iPhone XS or newer in September.
This release schedule allows Apple to gather feedback and make necessary adjustments before the official launch.
In conclusion, iOS 18 brings innovative battery management features to the iPhone 15, giving users more control and the ability to extend their device's battery life. This update reflects Apple's ongoing commitment to improving user experience and addressing battery life concerns. With iOS 18, iPhone 15 users can look forward to optimized performance and enhanced battery longevity.
