Question

How long should my Mac's battery last?


Answer

There are TWO (2) considerations that you should make when determining an accurate representation of your Mac's battery life. That is; the Make and Model of your current machine, and the Usage of your computer.

Make and Model:

All Scotch College laptops that are available to students are Apple Macbook Air's. These can be either the Early 2014 or the Early 2015 models. 

Below are Apple's direct statements regarding the expected battery life of BOTH the 2014 and 2015 Macbook Air models. Please be aware, you may or may not get the same results as these, depending on your usage requirements.

  • Early 2014 Macbook Air: 
    • 13 inch: Up to 12 hours wireless web. Up to 12 hours iTunes movie playback. Up to 30 days standby time.
    • 11 inch: Up to 9 hours wireless web. Up to 9 hours iTunes movie playback. Up to 30 days standby time.
       
  • Early 2015 Macbook Air:
    • ​13 inch: Up to 12 hours wireless web. Up to 12 hours iTunes movie playback. Up to 30 days standby time.
    • 11 inch: Up to 9 hours wireless web. Up to 10 hours iTunes movie playback. Up to 30 days standby time.
       

The difference in battery life from these two models is negligible. Be aware that Apple tests the battery life of these computers in conditions of use that are, more than likely, quite different to your own, meaning that there is no guarantee your laptop will go for that long.

To work out what make and model your laptop is:

  1. Click on the Apple Logo at the top left of the screen.

     
  2. A new window will appear that will list your Model of computer and Year of Production.

 

Usage:

If you are using more Wi-Fi i.e. watching multimedia content or editing photos/videos; then your battery life will be significantly less than if you were doing some light web browsing and word processing. This is due to the high power consumption and processing power required to use certain applications. 

Here are some ways to increase your battery life:

  1. Update to the latest software. 
  2. Turn off WiFi.
  3. Reduce your screen's brightness.
  4. Quit any unused applications.
  5. Unplug any unused peripherals (e.g. external hard drives).
