So our first step was to see if it actually is the case that “Edge gives longer battery time than Opera”? As Microsoft hasn’t revealed its full methodology, we were unable to run the same tests. If we get beaten in a test like this, we consider it a bug. Like most other engineering teams, we love it when someone picks a fight. Following the video was an extensive blog post and obviously a huge PR effort, and it was argued that the test showed that Edge beats Firefox, Chrome and Opera. This Monday, however, Microsoft released a video, similar to the one we made, showing Microsoft Edge winning in their test. Mostly because Edge is only available on Windows 10. One browser we didn’t pay attention to was Microsoft Edge. Our tests showed that the feature increased the battery life by as much as 50% when compared to other browsers, such as Google Chrome. This feature optimizes our Chromium/Blink based browser engine and user interface in order to give users more time to browse their favorite websites. This May, Opera became the first major browser to ship a dedicated battery saving feature.
