Understanding Battery Conservation Tips

The amount of work time your MacBook battery can provide before you need to recharge depends on the applications and peripheral devices you’re currently using and the steps you take to conserve power while you work.

For the best conservation of battery power, do the following:

ÂDisconnect bus-powered USB or FireWire devices when they are not in use.

ÂQuit open applications that you are not using.

ÂTurn off AirPort or Bluetooth when they are not in use. (Use the AirPort and Bluetooth status icons in the menu bar. If these icons don’t appear in the menu bar, you can turn them on in the Network and Bluetooth panes of System Preferences.)

ÂRemove CD and DVD discs when they are not in use.

ÂReduce screen brightness using the brightness controls on the MacBook keyboard.

ÂSet the hard disk to spin down after a short time. In the Energy Saver pane of System Preferences, select the “Put the hard disk to sleep when possible” option.

ÂSet your MacBook to sleep after inactivity of five minutes or less.

ÂYour MacBook is preset to automatically reduce its processing speed during periods of low processing activity when using battery power, thus reducing power usage. The setting that determines this is the Normal option in the Optimization pop-up menu of the Energy Saver pane of System Preferences. During periods of high processing activity, your computer will automatically switch to a higher processing speed. To conserve the most battery life, choose Better Battery Life from the Optimization pop- up menu. However, choosing this option may affect your computer’s performance. To set your computer to use its highest processing speed at all times, choose Better Performance.
