Apple's Magic Keyboard combines a sleek design with a stable scissor mechanism beneath each key and a built-in rechargeable battery that's charged via the supplied Lightning to USB Cable, meaning you don't have to mess about with replacing AA batteries.

The built-in battery is very long-lasting, and should power your keyboard for about a month or more between charges. If you're unsure how much charge is left, you can check the battery level at any time within macOS. The following steps show you how.

  1. Click the Apple symbol () in the menu bar, top-left corner of your Mac's screen.
  2. Select System Preferences....

  4. With the Keyboard tab selected, check the Keyboard battery level in the bottom-left corner of the window. This shows a percentage of battery life left in your Apple Bluetooth keyboard's batteries.

You can also check the battery level percentage from the Bluetooth menu, which can be accessed via the Control Center in your menu bar. You should see the percentage next to your Apple Keyboard, listed under "Devices."

If you don't remember to check the batteries of your Apple keyboard, don't worry – macOS will display a notification when the battery level falls to 10% or under.
