Surface Books instrumented for direct power measurement, running a looping browser test in a performance lab. This test supports Microsoft Edge as well as Google Chrome and Mozilla Firefox, so we can compare results across browsers over time. It can be used to look at specific sites and patterns, or measure complex workloads composed of many different sites in multiple tabs. It automates the most important tasks that people do with their browser, and runs through those tasks while measuring how much power a device is consuming, as well as how hard the CPU is working, how much traffic is being sent over the network, and more. One of the most important tools for our energy efficiency engineering is BrowserEfficiencyTest. These tests are repeatable by other browsers or curious users, backed by methodology documents and open source code. That’s why we always share our measurements alongside filmed rundown tests, or through open source tests freely available on GitHub. Measuring and improving battery life are both complicated problems, and while we want to show off our leadership here, we also want to be a part of a constructive dialog that improves the entire web. Our approach: open, transparent, and reproducible Let’s dive in to some details of how we measure power consumption to optimize for battery life, and how we’re engineering Microsoft Edge to be the most efficient browser on Windows 10. Direct measurements of average power consumption during typical browsing activities ( source code).

According to our tests on the Windows 10 Creators Update – based on an open-source test which simulates typical browsing activities across multiple tabs – Microsoft Edge uses up to 31% less power than Google Chrome, and up to 44% less than Mozilla Firefox. In this post, I’ll share some of the new energy efficiency improvements available with the Windows 10 Creators Update.Ĭomparing the latest versions of major browsers on Windows, the trends are similar to what we’ve seen with previous releases. We’re committed to giving you the best, fastest, and most efficient browser possible.

Windows users spend more than half their time on the web, so improvements here have a significant effect on your device’s battery life. We’ve been paying particular attention to this with Windows 10, and the response has been great. There’s a good chance you’ve noticed that Microsoft Edge and other popular browsers have recently been focused on improving battery life.
