Like an iPhone, a MacBook displays a small battery icon at the top of the display to show how much battery power remains. It's more helpful if next to this icon it also displays the percentage of battery you have left. To show the percentage, click the battery icon in the menu bar and click Show Percentage. (If you don't see a battery icon, go to System Preferences > Energy Saver and check the box for Show battery status in menu bar.)
