Since the iPhone was introduced with Face ID, it was impossible to show battery percentages within the bar of status because the notch took up a lot of space. Users had to lower the control centre on the iPhone to see what percentage of the battery remained.
In iOS 16, the battery percentage was added as a function, and when activated, it would display the percentage right over the battery icon on the Status Bar. The feature was available to all iPhones that have Face ID. I
It was unavailable on those with Face ID, such as the iPhone XR, iPhone 11, iPhone 12 mini, and iPhone 13 mini.
In the initial beta version of iOS 16 for developers, several users posted on the MacRumors forum that the feature for battery percentages will now let all iPhones equipped with FaceID notches display an amount over the icon for the battery.
