Announced that the team has been working to rectify Chrome for OS X battery hog complaints by just improving the performance of the browser on Mac, especially where Safari appears to do better.


Google Chrome for Mac has received multiple under the hood improvements, should point to a faster performance and longer battery life while browsing, which on OS X, the browser for instance, now requires significantly less CPU usage when loading and search results page and various other websites.

Before: Renderers for background tabs had the same priority as for foreground tabs.

Before: On a Google search results page, using Safari’s user agent to get the same content that Safari would, Chrome incurs ~390 wakes over 30s and 0.3% CPU usage vs. Safari‚Äôs 120 wakes over 30s and 0.1% CPU usage.
Now: 66% reduction in both timer firings and CPU use. Chrome is now incurring ~120 wakes over 30s and 0.1% CPU use, on par with Safari.

Before: On, Chromium incurs ~1010 wakeups over 30s vs. Safari’s ~490 wakes.
Now: ~30% reduction in timer firings. Chrome is now incurring ~721 wakeups over 30s.

Before: On, Chromium incurs 768 wakups over 30s and consumes ~0.7% CPU vs. Safari’s 312 wakes over 30s and ~0.1% CPU.
Now: ~59% reduction in timer firings and ~70% reduction in CPU use. Chrome is now incurring ~316 wakeups over 30s, and 0.2% CPU use, on par with Safari at 312 wakes, and 0.1% CPU use.”
