There is nothing worse when your battery on your iPhone is running down and you of course do the obvious things:
- Turn off push emails
- Turn down screen brightness
- Close out of your apps
- But there is a new one , put your iPhone into greyscale mode
Greyscale mode is a setting that eliminates all colour on your iPhone’s screen by making the display black-and-white.
By not displaying any colour, your phone is saving battery and the setting also lowers the brightness on your phone, which we all know helps preserve its battery.
