At the bottom should be “Show battery status in menu bar.” Make sure this is checked. Open up the System Preferences app and click on the “Energy Saver” icon shaped like a lightbulb. If you don’t see the icon in the menu bar, it may be turned off. If your battery is charging, it will have a lightning bolt symbol over the battery icon.
