Running Your MacBook Air on Battery Power
When the 45W MagSafe Power Adapter isn’t connected, your MacBook Air draws power from its built-in rechargeable battery. The length of time that you can run your MacBook Air varies, depending on the applications you use and the external devices connected to your MacBook Air. Turning off features such as AirPort Extreme or Bluetooth® wireless technology can help conserve battery charge.
If the battery runs low while you are working, attach the power adapter that came with your MacBook Air and let the battery recharge. When the power adapter is connected, the battery recharges whether the computer is on, off, or in sleep. The battery recharges more quickly, however, when the computer is off or in sleep.
