We all know how frustrating it is when your laptop runs out of charge whilst you are busy working. Fortunately, there are several methods for you to conserve your battery life and maximize your unplugged productivity.

  1. Firstly, to get a more specific indication of how much battery you have remaining; go to the upper right of the Menu bar and click on the Battery Icon, then select Show Percentage.

  2. Now your battery life will be displayed as a percentage giving you a better idea of when your laptop will want to shut down. 

Ways to conserve battery life:

  1. Be sure you have Updated your computer to the latest version of OS X.
  2. Check the Condition of your battery.
    • ​​​Hold down the Option Key as you click on the Battery Status Indicator.
      • Make sure the 'Condition' is 'Normal'.
      • If the Condition reads: Replace Soon please bring your computer to the Scotch Tech Centre for it to be repaired.
  3. Ensure that your laptop does not stay at 0% or stay at 100% for too long.
    • This is because staying at the extremes of the lithium battery in your laptop for too long can wear it out.
  4. Restore energy saver defaults.
    • If you have ever altered your energy saver settings on your laptop, and are currently experiencing battery issues; it is a good idea to reset back to the energy saver defaults. 
    • To do this:
      • Open up System Preferences and select Energy Saver. 
      • ​​Click the Lock to make changes and put in your password.
      • Then click Restore Defaults
        • ​​Doing this does the following things:
          • Turns the Mac off after 10 minutes of no use.
          • Turns the display off after two minutes.
          • Allows the hard disk to sleep when possible.
          • Dims the display when on battery power. 
  5. Dim screen and keyboard lights.
    • On your keyboard, turn down the Brightness of your screen as low as tolerable.
    • Turn Off the backlight keyboard completely.

  6. Turn off your Screen Saver.
    1. Go back into System Preferences and click on Desktop and Screen Saver.

    2. From here, make sure you change Start After to Never.

  7. Turn Wi-Fi Off when not in use.
    • This can be done by clicking the WiFi Icon from the top menu bar and selecting Turn Wi-Fi Off. 
  8. Turn off open Applications that are not being used.
    • It is important to pay attention to any opened apps that are not being used. These unused applications use up the existing RAM and processing power of your machine.
    • This can be done by Control + Click on the open application and pressing Quit
  9. Unplug unused peripherals (e.g. external Hard Disks, SD Cards etc.).
    • If you commonly transfer data to your computer with external hard disks and SD Cards, be aware that these use a lot of power, so be sure to eject them when not in use.
