Opera Denies Microsoft Edge Battery-Saving Claims (thestack.com)

An anonymous reader writes: According to the makers of the Opera browser, Microsoft's recent claim that its Windows 10 Edge browser is more power-efficient than Chrome are erroneous. Running its own tests with Opera, Edge and Chrome, the company finds that Opera runs 22% faster (with a battery life of 3hr 55m) than Edge (3hrs 12m). In Microsoft's own tests, Google's Chrome browser was the first to completely exhaust the battery, closely followed by Firefox and Opera. In May, Opera added a power-saving mode, but any advantage it can be verified to have in the energy-efficiency stakes may be more due to the native adblocking feature it introduced this year.

Ad blocking FTW

Any test needs to include uBlock Origin or the equivalent. Even Edge supports it now, I read. Otherwise any test data will be corrupted by random advertising altering the content and wasting as much battery power as it can.

Also, it's not clear that they even tried to match the laptop batteries. Maybe some where lower capacity than others, due to manufacturing variations and lifetime degradation.

Re:Forget about Edge. It's Firefox that's interest

The interesting part is actually how Firefox is the worst performing browser in the test.

Did you not even read TFS? Because:

Google's Chrome browser was the first to completely exhaust the battery

Which leads to:

We often hear from Firefox supporters that Firefox is more efficient than Chrome and other browsers.

It's clearly more efficient than Chrome, as per the results of this test.

I can't afford to be ideology-driven, as I'm a web developer and must test my work in all browsers. I'm comparing them side-by-side, day in and day out; yes, if you manage to wrangle all of Chrome's little sub-processes and add up their memory usage, Chrome is using more memory about half the time. Sometimes it swings in the other direction, and by about the same amount, so I'd say, honestly, on average they use about the same amount of RAM.
