Android 5.0 is now rolling out to various devices.
The update revamps the look and feel of the operating system and includes numerous new features, one of which is new battery saver mode.
When enabled, this feature will improve the battery life by reducing your device's performance and limiting background data.
It's really great for those times your battery's running low and you just can't seem to find a charger.
By default, battery saver mode is turned off.
However, a notification will appear on your phone, asking if you would like to enable it when your battery reaches 15%.
The easiest way to enable the feature is to swipe down all the way on the notification tray until you see the battery percentage.
Tap the battery icon.
Click on the menu button, that's that three vertical dot icon, and select battery saver.
From here you can set it to turn on automatically once your battery reaches 15% or 5%, or, you can manually switch it on.
When battery saver mode is enabled, an orange bar will appear at the top and bottom of the screen.
When you plug your phone in to charge, it will automatically turn off.
Google claims that enabling the battery saver feature will extend your device by up to 90 minutes.
