The battery status on the iPhone control center can be found by accessing the control center via the swipe down gesture from the top right corner of the screen on devices running iOS 12 or later. On the control center, the battery status is displayed in the top right corner as an icon in the shape of a battery. The icon will show the remaining battery life as a percentage, with a lightning bolt displayed next to the icon when the device is plugged in and charging. Additionally, users can also view more detailed battery information in the Settings app, under the "Battery" section.
