An anonymous reader writes: With the launch of the Windows 10 Creators Update and Edge 40 (EdgeHTML 15), Microsoft has released a new battery usage test that, naturally, trashes the company’s competition. This new test shows that Edge uses less power than both Chrome 57 and Firefox 52, and is bound to draw a response from its competition, especially Google, who doesn’t like it when Microsoft takes a jab at Chrome’s efficiency. The same thing happened last year, in June, when a similar test showcasing Edge’s longer battery life was met with responses from both Google and Opera. The most recent tests were performed for the launch of Windows 10 Creators Update. Two tests were carried out until a laptop’s battery gave out. For each browser, a minimum of 16 iterations were recorded per test. The first test measured normal browsing performance and the second ran a looped Vimeo fullscreen video. In the normal browsing performance test, Microsoft claims Edge used 31% less power than Chrome 57, and 44% less power than Firefox 52. In the second test, Edge played a looped Vimeo video in fullscreen for 751 minutes (12:31:08), while Chrome lasted 557 minutes (9:17:03) and Firefox for only 424 minutes (7:04:19). That’s a whopping three hours over Chrome, and five hours above Firefox.
