Charging and Discharging your MacBook’s battery

Whenever you plug-in the power adapter to charge the battery of your MacBook, always try not to remove the power cable before the MacBook gets charged to it’s full capacity. After which you can unplug the power adapter and get back to work on your MacBook. Once you are running it on Battery Power you should take care that you do not charge it again before the battery level reaches critical, say 20% (about which you will be notified accordingly) as repeated extreme discharging is harmful for the battery.

The best thing to do for laptop batteries is when you’re not using them, let them be somewhat discharged (40-70%), plug the computer into the wall power, and disconnect/remove the battery.

Dim your display and keyboard light

Your MacBook’s display and the backlit keyboard consume a considerable amount of power while operating on Battery. So it is always recommended to reduce the display brightness to a level which your eyes are comfortable with. Also you should generally turn off the Keyboard’s backlight and use it only when necessary, say when you are in a dark room.

Do not play DVDs/CDs

Your MacBook’s DVD drive plays both CDs and DVDs. The motor that spins the discs you put in the drive also consume a good amount of power. So you can consider copying your content (like movies and videos) onto your MacBook’s Hard disk or an USB external hard disk first and then watch the content from the hard disk. There is a drawback with Hard Disks too. Hard Disks spin too which again consume battery power. If you have solid state Hard Drives then it is well and good.

Do Not use many USB devices

You are a MacBook user and there is a 95% chance that you own an Apple iPod too! And the iPod may be always connected to your MacBook via USB ports when you are not on the move. USB ports again take up power to run the devices connected to them.

Turn OFF the Wi-Fi and Bluetooth Radios

Wi-Fi radio when ON keeps on searching for nearby wireless networks. So in case you are not connected to any Wireless networks nearby you should consider switching off the Wi-Fi radio. And again, if you do not use Bluetooth quite often, that can be turned down too.

Standby! Hibernate! Close the Lid!
