iPhone 15 Users Might Be Able To Limit The Phone’s Max Battery Charging

Apple announced the iPhone 15 and iPhone 15 Pro lineups during an event on September 12 and while it shared plenty of details, there are some that were not completely announced.

Now, a new report claims that one of those unannounced features is a new way to limit the iPhone’s charging.

The new feature, we’re told, will allow people to tell their iPhone not to charge its battery to the maximum capacity in an attempt to prolong battery life. This sounds similar to Apple’s Optimized Battery Charging feature, one that charges iPhones to 80% quickly and then holds the battery there until shortly before the iPhone expects to be taken off charge — at that point, it tops off to 100%.

That’s designed to help prevent battery fatigue, but 9to5Mac says that code found in the latest iOS 17 beta suggests a manual approach is on the way.

Based on code found in iOS 17 RC, which was released to developers on Tuesday, Apple has developed a new feature that will let users limit the maximum battery charge to better preserve its health. Once available, the option will be found in the Battery settings menu.

The report goes on to say that when turned off, the iPhone will charge as normal.

When the feature is turned off, users will see a message saying that the iPhone “will charge to its full capacity.” But when the feature is on, it will inform the user that the battery “will only charge to about X%.” The Settings app will also show when the iPhone was last recharged to the limit set by the user.

It remains to be seen if this feature will roll out to all iPhones or if it will be limited to the iPhone 15 and iPhone 15 Pro models. Those new models will go up for preorder on September 15 before going on sale on September 22.
