Charge the MacBook Pro battery
The battery in your MacBook Pro recharges whenever the MacBook Pro is connected to power.
Charge the battery. Connect your MacBook Pro to a power outlet using the included USB-C Charge Cable and 61W USB-C Power Adapter.
You can charge your MacBook Pro using either of the Thunderbolt 3 ports on your computer. The battery charges more quickly when the computer is off or in sleep.
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.
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. You can change your power settings in Energy Saver preferences (click the System Preferences icon in the Dock, then click Energy Saver). If your MacBook Pro is in sleep when a device is connected to it, the device’s battery may drain.
