Microsoft has renewed its war of words with Google and Firefox over who has the better web browser.
Perhaps unsurprisingly in the latest set of tests carried out by Microsoft, the company said that its own web browser, Edge, is better than the competition.
The Redmond based tech giant first pitted Edge against the other leading browsers in June 2016.
According to Microsoft, Edge is more power efficient and outlasted the other browsers by some distant.
In the test, Microsoft claimed Edge outlasted Chrome by some 3 hours.
Google responded to the video by rolling out a series of updates that boosted performance and saved it from placing too much demand on batteries.
Following the release of the Windows 10 Creators Update, Microsoft has now come back with a series of new tests.
The new tests pit Edge against Firefox and Chrome running on three identical Surface laptops.
Microsoft explained the conditions of the test in a blog post, where it said it measured the time it took each browser on the three Surface laptops to run down their batteries while streaming video from Vimeo in fullscreen mode. All three Surface laptops were running the Windows 10 Creators Update and connected to the internet using Wifi.
The tech giant said that Firefox managed seven hours of video streaming, while Chrome managed more than 9 hours. However, the Edge browser lasted a whopping 12 and a half hours, Microsoft said.
Microsoft says that because of battery life improvements in the Windows 10 Creators Update, the Edge browser is now more power efficient than ever and the company found that it uses 31 percent less power than Chrome and 44 percent less power than FireFox.
