Recently, Microsoft compared Microsoft Edge’s battery efficiency against Google Chrome, Opera, and Firefox. The company announced that Microsoft Edge consumes 70% less battery than Google Chrome. As you may expect, Microsoft Edge won the test because of the optimizations the browser includes. However, Opera then did their own test in which Opera beat Microsoft Edge. Opera’s test wasn’t exactly fair as they tested Opera with the built-in ad-blocker enabled — on the other hand, Microsoft didn’t use any ad-blockers during its own test. Now, the folks over at PCWorld did their own battery test for all of the leading browser — and unsurprisingly enough, Microsoft Edge won:
As you can see in the above results, Edge was followed by Chrome, Opera, and then Firefox. Internet Explorer 11, on the other hand, came last which isn’t really a surprise. In case you are wondering, PCWorld used EMBC BrowsingBenchmark to perform the tests on their Toshiba Radius 12 (Core i7 Skylake CPU, 8GB of RAM, an Ultra HD 4K Panel, and a 41-watt battery).
