Most efficient Mac browser Safari

By | October 15, 2015

Safari is the most efficient Mac browser using the least amount of battery power (amperage) compared to Firefox and Chrome on Apple MacBooks.  In a quick test of watching YouTube videos in browsers here’s how much battery/energy each browser used:

  • Safari: 1250 mA
  • Firefox: 1600mA
  • Chrome: 3600mA

Chrome is far and away the most power hungry web browser on Mac OS X, using nearly 3X the processing power and battery usage than Safari.

Obviously if you’re trying to maximize battery life on your MacBook, use Safari browser as its the most efficient.

To test this yourself, use the System Information application (Apple logo top right corner, About this Mac, More Info…, System Report, Power and look for the Amperage (mA) value).
