The iPhone 12 and 12 Pro users may see their remaining battery life in percentages. It's now possible to see your iPhone 12's battery % in a widget on your home screen. To see your battery percentage in the top right corner of the screen at all times, you'll need to update to an iPhone 12 from a previous version of the iPhone 12 to see the battery % on the phone at any time. Adding a widget to your home or widget page is the only way to see battery %.
