Don’t Leave Bluetooth Accessories Connected All Day

Bluetooth is efficient, but connected accessories can still drain battery life. If you keep headphones, keyboards, or other devices connected all day, your MacBook has to work harder to maintain those connections.

This usually isn’t the biggest battery drain on your Mac, but it matters when you’re trying to make every percentage last. It can also become more annoying if accessories keep waking your Mac or reconnecting when you don’t need them.

Apple recommends turning off Bluetooth when you don’t need it to save energy. You don’t have to do this every day if you rely on wireless accessories, but it’s useful during travel, on flights, during long work hours, or whenever you’re away from a charger.

You can disconnect accessories from Control Center or turn off Bluetooth in System Settings.
