Turn Your Screen Brightness Down

This seems like a no-brainer, but if your display is too bright, your battery will suffer the consequences, especially with bigger devices like your iPad or your Mac, or a larger iPhone model.

Turning down your brightness is as easy as opening the Control Center on your iPhone, iPad, or MacBook and dragging the brightness level down.

You can also use the F1 key on your MacBook or use the touch bar if you have a MacBook Pro.
