he latest battery efficiency test run by Microsoft put their Edge browser in the top position in comparison to Chrome and Firefox. In the tests, Edge used 31% less power than Chrome 57 and 44% than Firefox. While playing a Vimeo video, Edge lasted for 751 minutes while Chrome and Firefox ended up with 557 and 424 minutes respectively.
Microsoft has failed to prove it’s dominance in the realm of web browsers. Be it the Internet Explorer or Microsoft Edge. People aren’t using them. But Redmond has been very desperate to show-off Edge’s competence against others like Google Chrome and Mozilla Firefox.

Microsoft has already published two comparison tests last year in June and September. With the second test, they also put their BrowserEfficiencyTest on GitHub – a Selenium WebDriver based test automation project. It runs common tasks such as browsing through emails, Facebook feed, etc. done in multiple tabs. It records the usage of the CPU, battery, other resources with the help of Windows Performance Recorder.
