As of iOS 16, the numeric battery percentage has finally returned to iPhones, including the iPhone 14, but you need to enable it. Doing so couldn’t be easier. If you want to see the battery percentage on your home screen, simply navigate to the Settings app, then scroll down to Battery section. The first option you will see now is Battery Percentage, simply tap the toggle so it's green and you should now see the percentage in the top-right hand corner of your screen.
