The battery in your MacBook Air recharges whenever the MacBook Air is connected to power.

Charge the battery. Connect your MacBook Air to a power outlet using the cable and power adapter. To learn more about the adapter and cable that came with your MacBook Air, see What’s included with your MacBook Air.

Show battery status in menu bar. Add a battery icon to your menu bar so you can quickly see information about your battery and open Battery settings. In System Settings, click Control Center, then go to Battery on the right and click Show in Menu Bar. You can also choose to show battery percentage in the menu bar.

Customize battery settings. You can set different options for your battery in System Settings.

• Optimized Battery Charging: This feature helps to reduce the wear on your battery and improve its lifespan by learning your daily charging routine. It delays charging the battery past 80% when it predicts that you’ll be plugged in for an extended period of time, and aims to charge the battery before you unplug. In System Settings, click Battery in the sidebar, click by Battery Health, then turn on Optimized Battery Charging.

• Low Power Mode: This option reduces energy usage, so it’s a good option when you’re traveling or away from a power source for an extended period of time. In System Settings, click Battery in the sidebar, then choose an option from the Low Power Mode pop-up menu.

Note: To customize other advanced settings, like dimming the display on battery, preventing automatic sleeping, and when to wake for network access, click Options in Battery Settings.

Connect the power adapter. To charge the battery on MacBook Air, use the MagSafe 3 port with the USB-C to MagSafe 3 Cable connected to the power adapter, or one of the Thunderbolt ports with a USB-C Charge Cable connected to the power adapter.

Note: With the USB-C to MagSafe 3 Cable and the optional 70W USB-C Power Adapter, you can fast charge the MacBook Air up to 50 percent in around 30 minutes.

Check the battery’s charge. Look at the battery status icon at the right of the menu bar to see the battery level or charging status. Or go to System Settings and click Battery in the sidebar.

Battery usage history. Go to System Settings and click Battery to see your battery’s usage over the past 24 hours or the last 10 days.

Conserve battery power. To extend battery life on a given charge, you can reduce the display brightness, close apps, and disconnect peripheral devices you’re not using. In System Settings, click Battery in the sidebar to change your power settings. If your MacBook Air is in sleep when a device is connected to it, the device’s battery may drain.
