Since its launch on Windows 10 three years ago, Microsoft Edge has struggled to gain market share against rivals Google Chrome and Mozilla Firefox. Unlike its competitors who get major updates every six weeks or so, Microsoft Edge only gains every six months, following the pace or bi-annual Windows 10 releases.
If Microsoft couldn't find it as fast as its competitors do on its new web browser, the company has often highlighted that Microsoft Edge is the best browser for battery life on Windows 10 PCs. The company repeated these claims many times over the years, but for some reason, the company did not follow the release of the Windows 10 October 2018 Update this case.
The long blog post announcing the latest major update for Windows 1
As we've seen in the past, the company did a streaming video test using identical Surface Book updates connected to Wifi and running the October 2018 update. In the end, the Surface Book streaming the video in Edge 18 lasted approximately 16 hours, which is 24% longer than Chrome (almost 13 hours) and 94% longer than Firefox (8h16). The company didn't publish a video for this latest test, but these results are definitely impressive.
It's not clear why Microsoft didn't communicate more about this latest browser efficiency comparison, and maybe because the timing was less than ideal . Earlier this month, Microsoft announced that it was working on a Chromium-based version or Microsoft Edge which will launch in preview next year. Because it uses the same foundation as Google Chrome, this new browser probably has worse battery life than the current version of Edge, which uses Microsoft's own EdgeHTML browser engine. However, this may be the price to pay for having a browser that has lesser compatibility issues and a much larger selection of extensions.
