I added in a segment about the Onscreen Keyboard’s vibrate when typing setting and how to turn it off to save battery, here it is:

Also if it doesn’t bother you turn off the touch screen keyboards vibrate ability, to be more clear whenever you hit a button on the onscreen keyboard the phone vibrates. This wastes battery if you are fine just typing and not having your phone move around underneath you so to turn this off go to Settings>Language & Keyboard>Touch Input>Text Input>and turn off Vibrate when typing.
