The battery indicator for your iPhone 5s is located in the top right corner of your iOS device. You can have a rough estimation of the power supply left in your device by checking the battery graph. The emptier the battery “content” the less juice is left in your iPhone’s tank.
However, you can have a highly more accurate reading of the energy levels, of your iPhone 5s, by enabling the battery percentage indicator available with iOS 7. A precise scale of 1% to 100% keeps you permanently updated with the remaining lifetime.
How To Enable/Disable
The battery percentage indicator is not enabled by default on your iPhone 5s. You have to tap on “Settings”, select “General” and navigate to “Usage”. Scroll down to the “Battery Percentage” tab and turn the indicator on by tapping the switch. The remaining battery juice will be immediately displayed in the top right corner of your iPhone’s screen next to the remaining battery graph. Tap the switch again to disable this feature!
