The iOS 9 update brought along a helpful feature called Low Power Mode. This setting provides a simple way for you to quickly modify several settings that can needlessly drain your battery. While you had been able to make these changes yourself in the past, the addition of Low Power Mode made it much easier.
Our tutorial below will help you find the Low Power Mode setting on your iPhone 5 so that you can enable the feature that is associated with the yellow battery indicator that you might have previously noticed on your device.
Turn on Low Power Mode on an iPhone
Step 1: Tap the Settings icon.
Step 2: Open the Battery menu.
Step 3: Tap the button to the right of Low Power Mode to turn it on. The setting is enabled when there is green shading around the button, and when the battery icon at the top-right of the screen becomes yellow.
- Low Power Mode can be activated manually using the steps below. It can also be activated through a pop-up that appears when your remaining battery life drops below 20%.
- You can tell that Low Power Mode is enabled by looking at the battery indicator at the top-right of the screen. A yellow battery icon means that Low Power Mode is turned on.
- Low Power Mode will remain on until you reach 87% remaining battery life. Once your iPhone is charged to that level, Low Power Mode will be disabled, and the battery icon no longer be yellow.
- The following changes are made when Low Power Mode is activated: Mail fetch, background app refresh, automatic downloads, and some visual effects are reduced or turned off.
