Despite the smaller notch, the iPhone 13 series will not show users the battery percentage in the status bar or at least not by default, according to the iPhone 13 emulator built into Xcode.
The entire iPhone 13 series has a smaller notch, allowing more content viewing space. While many users may have hoped that a smaller notch would drive it Apple to display the battery percentage in the status bar, this does not seem to be the case, at least for now.
Such as was noted on Twitter, the Xcode 13 simulator for the iPhone 13 Pro Max shows the status bar without the battery percentage, despite plenty of room to shift the signal and Wi-Fi lines to the left. While the Xcode 13 emulator, released after yesterday's event, does not show battery life, Apple may offer it as an option on Settings.
Apple is unlikely to put the percentage of the battery in the status bar without offering a way for users to turn it off if they wish. With older iPhones that do not have a notch, Apple includes an option in the settings to turn the percentage on or off and something similar could be done with the iPhone 13. Although it is worth noting that none of the iPhone marketing images 13 or updated iOS 15, does not portray it as a possibility.
The iPhone 13 and iPhone 13 Pro will start shipping to customers on Friday, September 24, but we expect reviews and practical impressions of the devices to be released before that. These reviews and impressions will give us a definitive answer as to whether Apple will eventually allow customers to display their battery percentage in the status bar, instead of having to swipe down in the right corner of the screen.
