Microsoft uploaded a new marketing video to promote its Edge browser. The software giant claims Edge is by far the most energy efficient browser, as evidenced by its test on four identical laptops. The laptop with Edge lasted over 7 hours and 22 minutes in the test, which is 70 percent longer than Chrome, 43 percent longer than Firefox and 17 percent longer than Opera with Battery Saver enabled. Full details of the test can be read at the Windows blog.
What happens when three identical devices run on different browsers? The Microsoft Edge team wanted to find out. This experiment showed that battery life on a PC running Microsoft Edge lasts 70% longer than Chrome, 43% longer than Firefox , and 17% longer than Opera (with Battery Saver enabled).
Further optimizations will be rolled out with the upcoming Windows 10 Anniversary Update, which includes power saving updates for both Edge and Windows itself.
