Win7 VS Win8 who has more power to endurance?

Endurance is the standard for evaluating the power consumption of an operating system. As we all know, the kernel of the WIN8 system has been upgraded from Win7 NT6.1 to NT6.2, does the kernel upgrade have any improvement on the endurance? Below we'll tell you the answer through a review video.

Test process:

We have used two hardware configuration identical Lenovo Yoga notebook, one carries Win7 flagship edition, the other carries Win8 Professional Edition. Both computers are equipped with power Mark, a commonly used laptop test software that simulates a variety of day-to-day operations to get the system's endurance.

First of all, we have the two devices to the maximum brightness, power plans are selected "High-performance", the electricity is 100%.

Then open the Powermark software, set the test mode to "full test" (high load), the test time limit is "remaining 20%". Then choose "Test", the system began to automatically open the Web page, watch video and other operations.

At this point, what we need to do is wait and see if the two machines have more power to hold the battery for longer.

Three hours later, we're back in the evaluation room. The test results have come out: Power Mark shows that the WIN8 system lasts 3 hours and 24 minutes in a high load operation, while Win7 is 3 hours and 06 minutes. Win8 more than Win7 18 minutes of high load endurance.

Win8:3 Hour 28 min

Win7:3 Hour 9 min

Evaluation Summary:

18 minutes seems not to be long, but when you are worried about electricity, this time will appear invaluable. It seems that the upgrade of the WIN8 kernel can actually reduce energy consumption and make more efficient use of hardware resources, thus prolonging device endurance. The user who has the requirement to the notebook endurance, may wish to choose a Win8 equipment.
