Microsoft Edge browser is more power saver

Microsoft said that Edge browser is more power saver than any other browser in the market. A new test conducted by Edge team shows that users can browse longer with Microsoft Edge than with Chrome, Firefox, or Opera on Windows 10 devices. Edge team also recorded time-lapse videos of each browser until the battery dies. Check yourself.

For demonstration Edge team compared power consumption in a controlled lab environment. The Edge team also collected data from a real-world energy telemetry from millions of Windows 10 devices.


Energy efficiency improvements in the Windows 10 Anniversary Update

Background tabs are more efficient: With the Anniversary Update, Microsoft Edge only executes background JavaScript timers once per second in background tabs. More importantly, these timers are coalesced with other work happening across Windows. Microsoft Edge doesn’t wake up the hardware to perform work. Instead, we tag along with other work happening across the system, and then quickly yield, allowing the hardware to enter a low power state.

Flash is more efficient: Flash ads are common on the Internet and they can have high battery cost, primarily through continuous animations which continually consume CPU, GPU and display resources. In the Anniversary Update, Flash is now running inside a separate process, and controls which aren’t central to the page are paused by default. Users who want to interact with Flash can simply click the control. And given Flash is now running in a separate process, we can monitor and control the resource impact of Flash. When Flash consumes too many resources or crashes, we can stop the Flash process without impacting the website.

Microsoft Edge’s user interface is more efficient: The Microsoft Edge user interface has been optimized for power efficiency. Animations are an important part of the Windows 10 and Microsoft Edge design language, but animations can consume considerable power if they perform more work than necessary.

Windows networking is more efficient: The new TCP Fast Open (TFO) feature allows connections between the device and the server to be setup faster with fewer messages. And the TCP stack now includes an optimized Initial Congestion Window (ICW) with a larger maximum message size, meaning fewer messages have to be exchanged with the server. Fewer messages mean the wifi antenna can be turned off sooner, saving energy. We’ve also added features called Tail Loss Probe (TLP) and Recent Acknowledgement (RACK) which reduce the time required to correct for lost packets. If it’s likely that a message is going to time out, we send a request for the data again sooner than the normal timeout. Doing this allows us to switch off the wifi antenna sooner when you have a poor connection.
