iPhone 4 for Dummies: Display numeric percentage % battery life

By default, your iPhone does not display the % (percentage) of battery charge remaining on your mobile.

To get this to display you just need to follow these 4 easy steps:

1) Click on the <Settings> icon

2) Select <General>

3) Select <Usage>

4) In the first row, you will see <Battery Percentage>, toggle this field to "ON".

That's it!  You should be able to see the % battery life left on the top right hand corner where the little battery icon is.
