Browser efficiency comparison - Webdriver Windows 10 Creator's Update Methodology summary. The Microsoft Edge team measured the average power consumption of the CPU, GPU, and Wifi antenna while Microsoft Edge, Chrome, and Firefox ran a representative set of user activities in each browser, automated through WebDriver. Looking at the Chromium based browsers, which are the new Edge, Chrome, and Opera, and they all more or less fall in the same range, with only twenty minutes of runtime between the three, but as. Average power consumption per browser based on billions of data points of aggregated telemetry. These numbers are from actual Windows 10 (version 1511) use “in the wild,” not artificial tests or hypotheses. People using Microsoft Edge simply get more out of their battery every day. Experience the difference (time-lapse videos). Brave's study findings are, broadly, similar to another assessment of browser power usage by Greenspector, a startup focused on monitoring energy consumption. Google, Mozilla and Microsoft didn't. Best web browser 2021: Chrome, Edge, Firefox, and Opera go head-to-head. Before Chrome, Opera was a popular choice among power users. Opera is really one of the more under-rated browsers around.

Microsoft’s Edge may have the lowest market share among the leading desktop/laptop web browsers, but it has had the best battery life for the past two years. Market-share leader Chrome comes in second but it’s narrowing the gap.
Microsoft runs regular battery life tests comparing Edge, Chrome and Mozilla’s Firefox. The test involves using the browsers to play the same film on three identical Surface Books. In the most recent test, Edge lasted 14:20:07 compared to 12:32:58 for Chrome and 7:15:16 for Firefox. Put another way, Edge lasted 14% longer than Chrome and an immense 98% longer than Firefox.
Here’s a table showing Microsoft’s demonstrations of Edge’s advantage over Chrome and Firefox beginning in 2016. When you look at the changes over time it’s clear that Chrome is steadily closing on Edge in terms of battery life. What’s going on with Firefox is anyone’s guess.
Date | Chrome | Firefox |
May 2018 | 14% | 98% |
December 2017 | 19% | 63% |
April 2017 | 35% | 77% |
June 2016 | 70% | 43% |
Net MarketShare estimates that Edge had 4.5% of the browser market in April. That’s not much compared to Chrome’s 61.7%. Firefox has a 10.2% share. (Percentages are rounded.)
Getting comfortable with more than one browser can be time consuming, but if you use Chrome or Firefox, use your browser on battery frequently, and regularly run into charging problems, it might be helpful to switch to Edge when your computer is not plugged in.
