7. Save up to 60% battery life

We’ve been consistently impressed with how long the iPhone X lasts. On many occasions, it lasts up to a day and a half.

Putting you phone in low power mode will extend the battery life even further. But you can extend battery life even more, by up to 60 percent according to AppleInsider’s tests, simply by using black wallpaper, inverting colors to create a pseudo “dark mode,” and by turning on grayscale mode.
