iOS 18 improves the battery charging limits for the latest iPhone models, specifically the iPhone 15 series, by providing more granular control over the charging limits. Currently, there is a setting that stops the phone from charging beyond 80%. With the update to iOS 18, users will have additional charging limit options set at 85%, 90%, and 95% of full charge. This allows users to choose a specific charging limit that best suits their needs and potentially improve their iPhone battery's lifespan by reducing the time that the battery is fully charged5. The new charging limit options will be available in the Settings app under Battery → Charging.
iOS 18 will introduce new specific charging limit percentages for iPhone 15 models, including 80%, 85%, 90%, 95%, and 100%. These options will allow users to have more control over their battery charging habits and potentially improve the battery's lifespan by reducing the time that the battery is fully charged4.
The new feature in iOS 18 that allows users to see the time even when the iPhone battery is completely depleted is an enhancement to the existing Power Reserve functionality2. With this improvement, the top left corner of the display now shows the time during the period when the iPhone battery has discharged but remains findable through the Find My feature6. This addition is particularly useful as it provides users with essential information even when their device is out of battery. However, this feature appears to be limited to iPhone 15 models for now.
