Battery Time Remaining Click to see a larger image

On a notebook Mac, there is a battery indicator in the menu bar with the other status icons on the left. You can click on the battery indicator to see an estimate of how much time you have remaining on your battery life.

Here are the different battery icon states and what they mean:

• You are running on battery power. The filled space of the battery gives you a rough idea of how much time you have remaining on the charge. The filled area will turn red when you have very little battery power left.
• Your battery is charging. If you click on the battery indicator icon when the battery is charging you will get an estimate of how much longer the batter needs to charge to get to full.
• Your battery is fully charged.

Some Mac notebooks also have a button on the battery on the bottom of the computer that you can push to see how much battery charge is remaining. You can do this even while the Mac is asleep.
