Several subtle changes to the user interface have been made in iOS 7, the biggest one being animations, which brings the device to life through the engagement of advanced physics and other visual effects.
One of these animations is the new parallax effect, which gives the illusion that the home screen is multilayered, with the applications and background wallpaper each on their own separate planes. Tilting the device around brings the feature to life, using the iPhone's gyroscope and accelerometer to change the orientation of certain planes.
While the feature may be good-looking and fun to play with, it uses up battery, just like every other feature on your device. If you want to save a little bit of battery and aren't really feeling the parallax view, here's how you disable it.
If you want to disable parallax, simply head over to Settings -> General -> Accessibility -> Reduce Motion and turn it ON.
Once Reduce Motion is enabled, you'll see the parallax effect reduced in the icons, background, and alerts.
