Microsoft trashes Google’s latest Chrome battery life claims

Microsoft kicked off a battery life war with Chrome and Opera earlier this year, and Google finally responded last week. Microsoft's original tests showed exactly how bad Chrome is for laptop battery life, but Google's response was packaged in the release of Chrome 53 with CPU and GPU power consumption enhancements for video playback. Google even made a video with Surface Books, just like Microsoft, to compare its battery life improvements to previous versions of Chrome. Microsoft isn't convinced Google's latest browser update is that much better, though.

In a new blog post, Microsoft has tested Edge and Chrome battery life on a Surface Book running the latest versions of Chrome and Edge (from the Anniversary Update). Using the same Netflix test (looping a streaming video), Microsoft claims Edge lasted 8 hours and 47 mins, compared to 6 hours and 3 mins for Chrome. That's 45 percent longer than Chrome, and 69 percent longer than Firefox. The only browser that comes close is Opera with 7 hours and 8 minutes of battery life, but Edge still lasts 23 percent longer.

Streaming Netflix video isn't the only way to test battery life, and there are a number of different services. "The Chrome team recently released a similar video where they focused on comparing the latest version of Chrome to a release from last year to demonstrate some improvements, however they didn't include other browsers in this test," says a Microsoft spokesperson. "Because the format was so similar to our tests, we shot a second video to compare like for like, this time using their methodology: looping a video from Vimeo, instead of Netflix." The Vimeo test still has Edge outperforming Chrome by more than an hour, but the gap has clearly been closed here as Edge only lasts 11 percent longer in this particular test.

Microsoft is also releasing real world data of power consumption per browser from millions of Windows 10 machines. Microsoft's latest statistics show that Edge power consumption is nearly half that of Google Chrome, and the company claims this is consistent with its own lab tests. While Microsoft has been highlighting Chrome's poor battery performance, Google's browser is still the most popular on desktops. StatCounter data suggests that Chrome is still rising in popularity on the desktop, despite Microsoft's efforts with Edge. Microsoft still has a long way to go to convince Windows users to switch away from Chrome.


pffff stop trying to make edge happen


I think you and everyone should be thankful Microsoft is showing proper comparisons and bringing awareness to Chrome’s atrocious toll on battery life and memory, it will lead to a better Chrome !

As for Edge, this initiative does work ! I got a feeling many here with a laptop running Windows 10 will switch to edge when battery is low or altogether, knowing what a power hog Chrome is.

I think you should pay attention to the "/s"

I hope it stands for ‘sucky’ sarcasm.

You’ve just validated the need for something more obvious.

For what it’s worth, I do actually agree with your points.

I disagree, this is great for competition. Hopefully Google will keep pushing to improve battery consumption in Chrome.

see above.

Noted, sorry.

i’m not your buddy, pal

I’m not you pal, friend.

I wonder how long a computer running the last version of safari would do on this test.
On OSX, Safari is multiple times better than chrome so i can’t help but wonder how good Apple’s Windows chops were.

Safari for Windows was discontinued several years ago.

Note the use of the word ‘last’ and past tense context.

Safari for Windows was ass.

Note the use of the word ‘last’ and past tense context.

Safari for Windows was abandoned about half a decade ago. You can see why he’s nonplussed about running the test with a 6 year old browser. Especially since it wasn’t better than Chrome on Windows back then.

And it was horrible, buggy and very slow when it was available.

I guess I haven’t investigated someone’s real numbers testing, but Firefox on macOS seems to do just fine with not hogging up too much battery life.

It ended at Safari 5 iirc? Which wasn’t great even in its time. Safari only came into its own in the last few versions/OSs.

Safari was as good as Internet Explorer and Firefox, IMO. The reason why most people didn’t use it is because it didn’t have the Add-On ecosystem of Chrome and Firefox. THe only thing I require is a Content Blocker. If they had that on an updated Safari for Windows which Synced data with macOS and iOS devices, I’d use it exclusively. I used Safari back then for that reason. Reader List, Bookmark, etc. synching between devices without the need for clunky control panels and "extra accounts" (Google/Microsoft Account, when I use literally none of their services).

I am loving how people are being religious about browser and platform use though. Pure comedy.

I just use the solutions that give me the highest productivity and convenience, without having to expose myself more to the internet. Has worked well, thus far.

If you look at light normalized for the two Macbook Air you should get a reasonable estimate between safari browsing on maxos and other (IE or chrome) on win8 normalized to equal battery capacity. I’d say from that safari seems more or less equal to non-edge browsing in windows. (I’m assuming IE as I’d expect chrome to be even lower).

Apple has never been known to make particularly good software for Windows

With AD Block Plus, Edge has become my preferred browser. It’s definitely lean and works well for me.

All they need is a login/profile where I can sync history, bookmarks, and passwords with any device’s Edge browser and I’d be 100% sold.

Yeah this.

They need Edge on iOS and Android. It could just be a shell around webkit and I’d be happy.
