iOS 18's Battery Section Tells You If You Used a Slow Charger

Apple updated the Battery section of the Settings app in iOS 18 to add a feature that lets you know if you charged your iPhone with a "slow" charger.

Periods of slow charging are shown with an orange bar in the portion of the Battery settings that show battery usage and charging over the past 24 hours or the past 10 days.

We saw the slow charging notice after charging with a 5W wireless charger, as did a Redditor who highlighted the feature. It's not clear what exactly is considered "slow," but the designation is useful for those who are seeing slow charging speeds and aren't sure why.

Many wireless chargers claim to be MagSafe while being limited to Qi speeds or below, so this feature could help ‌iPhone‌ users understand why their devices aren't charging at optimum speed. There does not appear to be an option to enable an alert when charging from a slow charger, which could be an arguably better feature because the battery settings are somewhat hidden.

There is a tappable information button that accompanies slow charging notices, but as of right now, it goes to a support document that does not yet exist.

I always use the 5W power adapter for my iPhone SE3 and the 12W power adapter for the iPad 9… this new feature makes it look like it is a bad thing to charge your device slowly, but I think it’s quite the contrary, right?

Yes...iOS 18 uses advanced on-device machine learning combined with the power of Apple’s latest chips to determine exactly what speed your phone is charging at. This is Something Only Apple Can Do™
What is wrong with you all... This feature is on ALL iPhones with iOS 18. I have it on my iPhone 13 in the beta.

Faster charging == Faster Battery Decline == Faster Replacment. Tim Apple approves. Mother Earth did not reply when requested for her thoughts.
