iOS 18 released on September 16, bringing a host of upgrades to the iPhone, just in time for the arrival of the iPhone 16, iPhone 16 Plus, iPhone 16 Pro and iPhone 16 Pro Max.
All new iPhone 16 models support fast charging, and a new feature added with iOS 18 suggests the company may want users to take advantage of the capability. That’s because iOS 18 adds a new “Slow Charger” alert to the Battery section of the iPhone’s Settings app, which will appear when you’re consistently using a slow charger.
A new orange color will appear on the battery level graph to indicate periods of slow charging, as opposed to green color for periods of fast charging.
At this point, we don’t know what charging speed will cause the “Slow Charger” warning to appear. And we don’t know what Apple means by fast charging.
If MacRumors Reports have suggested that the iPhone 16 series will support charging speeds of up to 45W, but the spec sheets on Apple’s website only list a 20W USB-C charging speed and a 30W MagSafe charging speed. It will be up to Apple to confirm whether the iPhone 16 series will indeed support 45W charging.
iOS 18 also gives users the ability to set a charging limit at 85%, 90%, and 95%, in addition to the previously available 80% limit.
Like many other smartphones, iPhones offer users the ability to limit charging to a certain level in order to extend the overall life of the battery. After all, the battery is a consumable that will degrade over time.
It is generally believed that lithium-ion batteries, such as those in iPhones, last longest when charged between 20% and 80%. However, this theory has also been criticized.
