iOS 18 will warn you when you’re using a slow iPhone charger

iOS 18 includes some notable changes to iPhone battery health and charging settings. Apple has added more charging limit settings for iPhone 15 users, as well as insights into when you’re using a slow charger.

In the iOS 18 Settings app, iPhone 15 users will see multiple options to set a charging limit in the Charging section of the Battery menu. Previously, Apple allowed you to set a charging limit of 80%, but Apple has now added more granular options to set charging limits of 85%, 90%, and 95%.

iOS 18 also includes a new feature that can tell you if you’re using a slow charger to charge your iPhone. In the Settings app, choose the “Battery” menu and check the battery level graph. If you’re actively charging with a slow charger, you’ll see a warning message. The graph itself has also been updated with a new orange color, which indicates that a slow charger is being used.

It’s not clear at this time what charging speed triggers the “Slow Charger” message. However, it’s helpful to have this context.
