Brave ran some benchmark tests on the Android version of its browser, and – funnily enough – found it to be less power-hungry than a handful of competitors.
Specifically, the benchmark involved running battery-historian, an open-source testing tool. Using a Samsung Galaxy S9 running Android 9.0, Brave's researchers compared Chrome, Firefox, and Edge alongside browsers designed or configured to block ads including Firefox with uBlock Origin plugin, Adblock Browser, Firefox Focus, and Kiwi.
The testing tool loads a series of websites in a new tab, waits five seconds and scrolls over the page multiple times for about 30 seconds. This routine gets executed over about 11 minutes, and gets repeated five times per browser, amounting to about an hour of browsing time per browser.
"In our research, we show that Brave consumes 40 per cent less battery than popular browsers like Chrome, Edge, and Firefox, thanks to a combination of bandwidth savings and lower CPU pressure," explained the San Francisco-based software maker on Monday. Compared to the ad-blocking browsers, Brave still consumed less battery power, as much as 20 per cent less, though Firefox with uBlock Origin, at 90mAh, on average, was close to Brave's sub-80mAh.
The bandwidth savings, and associated lower CPU usage, come from Brave's blocking of third-party tracking code and ads. With less data to download, there's less Wi-Fi usage, less for the CPU to process, and ultimately less demand for battery power.
Not too exciting
Blocking ads and trackers has long been known to improve browser performance. In 2017, browser maker Opera reported that on desktop browsers, ads and associated code account for more than half the load time of web pages. Also, it said that laptop battery life drops by about 13 per cent when ad blocking is disabled.
But Brave owes its efficiency to more than just exiling ads. It also also bested ad blocking browsers, or so the company claims, with battery savings of about 20 per cent. That's the result of lower CPU usage, the company contends.
In terms of bandwidth consumption, however, Brave scores about as low as the Adblock Browser.
Brave's benchmarks may soon change however: the company last month began testing opt-in ads in its developer build, and is in the process of making its own ad system more widely available. ®
