Microsoft did a battery test to show that Chrome is horrible with laptop batteries. That was a while back. Recently, Google replied to their tests to say that with Chrome version 53, things are much lighter on battery life.
Now, Microsoft has responded to that response, with more tests.
In a new blog post, Microsoft has tested Edge and Chrome battery life on a Surface Book running the latest versions of Chrome and Edge. This test also uses the same Neflix video looping to check battery life.
Microsoft claims Edge lasted 8 hours and 47 mins, compared to 6 hours and 3 mins for Chrome. 45% more compared to Chrome. Here is the video that Microsoft posted on their blog:
From the blog post:
The Chrome team recently released a similar video, where they focused on comparing the latest version of Chrome to a release from last year to demonstrate some improvements. However, they didn’t include other browsers in this test. Because the format was so similar to our tests, we shot a second video to compare like for like, this time using their methodology: looping the same video from Vimeo, instead of Netflix. In this test, Microsoft Edge lasted even longer – more than 13 hours! – and still beats Chrome by more than an hour. Microsoft Edge even lasted 62% longer – more than five hours! – when compared to Firefox.
