Internet Explorer 10 is rated the most in tests.
Tests on the power consumption of each browser showed that normally, three browsers Firefox, Chrome and IE 10 are almost no difference. However, if you use these three web browsers to open Flash or HTML5 videos, Microsoft's browser takes the most advantage.
IE 10 is the best power saver compared to two rivals Firefox and Chrome.
When playing Flash videos, IE 10's power consumption is significantly lower than the other 6W browsers. Besides, Microsoft browser always ranks highest in power saving ability when running on both laptop and desktop computer.
According to Slashgear, the reason IE 10 recorded better results than the two competitors is because it is optimized for support on Windows 8 operating system while Firefox and Chrome are only third-party software vendors.
