| Battery Low Power Mode | To enable Low power mode, open the settings app in iOS 10, then choose the Battery parent menu. From here a toggle switch for low power mode can be turned on.
| Turn On Auto-Brightness | This helps save battery and makes it easier to see. Turn Auto Brightness on and you'll save energy because your screen will need to use less power in dark places.
| Stop Motion & Animations | It's subtle but if you move your iPhone and watch the app icons and background image, you'll see them move slightly independently of each other, as if they're on different planes. This is called a parallax effect. It's really cool but it drains battery. You may want to leave it on to enjoy the effect, but if not, you can turn it off.
