Microsoft's test found that Chrome is the browser that will most reduce laptop batteries

When Microsoft examined how much each web browser affects battery consumption on a notebook PC equipped with Windows 10, it turned out that Google Chrome was the most "battery-hungry" browser.

The four browsers used for testing are Mozilla Firefox, Microsoft Edge, Google Chrome, Opera.

This is a graphical representation of the power consumption of each, and color coding indicates consumption by CPU usage, GPU usage, and Wi-Fi usage, respectively. The left end is the reference value when the browser is not activated, and the power consumption is 318 mW (milliwatt). The lowest power consumption is 2068 mW at Microsoft Edge, followed by 2819 mW by Chrome, 3077 mW by Opera, and 3161 mW by Firefox.


In order to show that these figures are not desk-top, Microsoft actually introduced Windows 10 "Surface Book"We launched the browser and conducted a survey of actual equipment.

The movie begins when the test lasts 3 hours.


Both 4 cars have crossed over, but in 4 hours 19 minutes 50 seconds, the Surface that was running Chrome is out of battery.


In 5 hours, 9 minutes and 30 seconds, the Surface that was running Firefox is out of battery.


The remaining two are over 6 hours.


However, in 6 hours 18 minutes 33 seconds Opera also exhausted ... ...


Over 7 hours ...


It was 7 hours 22 minutes and 7 seconds that the battery of the surface which started Edge was burned out.


In the graph of power consumption, Chrome should have been the second lowest behind Edge, but in real life it was said to be the browser with the most battery consumption.

If you use a Windows 10 terminal for a long time with a battery only when you are away from home, using the Edge may keep the battery longer than using other browsers.

By the way,With MacBook Pro Safari has longer battery life than Chrome and FirefoxI know that.
