Some iPhone owners making the upgrade to iOS 16 will be disappointed to find the new battery percentage display in the status bar isn't working.
As MacRumors reports, this isn't a bug. Apple updated a support document to confirm that the battery percentage won't be displayed in the status bar on some older iPhone models. More specifically, the iPhone XR, iPhone 11, iPhone 12 mini, and the iPhone 13 mini will only show the visual representation of battery level.
Adding the battery percentage to the status bar was high on the list of requested features by iPhone users, and Apple finally delivered it alongside a bevy of other new features in iOS 16. It's a more convenient way of seeing how much battery you have left without having to swipe down from the top-right corner of your display. Apple hasn't explained why these four models of iPhone can't show the percentage.
If you own an iPhone that supports the battery percentage display, it can be enabled by navigating to Settings > Battery. The iPhone SE (2nd and 3rd generation), iPhone 8 or earlier, and all iPad models always show the battery percentage in the status bar. Another way to view battery information is by adding the Batteries widget to your Home Screen or Today View.
