Microsoft Edge and Opera clash over browser battery consumption, but Google Chrome still the worst

Earlier this week Microsoft cast shade on its web browser rivals, benchmarking the energy efficiency of Edge, Chrome, Firefox and Opera on a Microsoft Surface.

Opera's test shows it performs better than Edge

Perhaps predictably, Microsoft’s new-to-market browser performed best on a Microsoft Surface running the Windows operating system.

Attacking Microsoft’s lack of transparency in its failure to fully release its methodology saw Opera run a test of its own, unable to copy Microsoft’s conditions.

Opera said on its blog: “[The Microsoft test was followed by 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.

“Like most other engineering teams, we love it when someone picks a fight. If we get beaten in a test like this, we consider it a bug.”

Opera, with a naive ad blocker and power saver enabled, lasted longer than Edge and Chrome on Windows 10. In the Opera test, Opera lasted 22 per cent longer than Edge. Google Chrome, a silent bystander in this clash, performed the poorest again.
