Which one is more power efficient, win10 or win8.1?

Regarding win10 and win8 systems, we sometimes want to know which of the two systems is more power-saving and has better battery life. Regarding this issue, the editor believes that although win10 is excellent in performance optimization and runs extremely smoothly, these optimizations have caused relatively large consumption. Compared with win8, the battery life of win10 is slightly weaker, but it is still excellent in terms of efficiency.

Which one is more power efficient, win10 or win8.1:

Answer: win8.1 is more power efficient.

Battery life is the key to notebooks. In order to improve the battery life of the device, Windows 10 has brought new battery saving features. I believe it will definitely become better than win8 in the future.

Win10 and win8.1 test comparison:

1. Settings:

Power saving mode is included in the early technical preview version of Windows 10 One of the new features, but it was not activated until the version in January this year.

To turn on this feature, you need to run the Settings application (shortcut key: Windows I), and then enter System > Power Saving Mode. In the initial interface, you will see the current battery level and estimated usage time.

When activated, Battery Saver Mode saves power by limiting background activity. You can turn it on manually, or use the power-saving mode setting below to turn it on automatically when the battery reaches a certain level.

2. Battery usage:

If you want to know whether restricting the running of background applications is effective, perhaps you should first observe their original power consumption Condition.

Click on the battery usage in the interface, and you can see the power consumption of the system, screen and Wi-Fi in the past 1 week/2 days/24 hours. Below it is also displayed the respective power consumption percentages of foreground and background applications.

Take the Lenovo Yoga Pro 2 used in the test as an example. In the past week, the display power consumption of this device was about 11%.

In terms of software power consumption, more than 98% is consumed by foreground applications, while less than 2% is consumed by background applications.

It can be seen from these data that the power consumption of background applications is actually very low. Therefore, closing background processes will not have much impact on the battery life of Windows 10.

Currently, there is a big limitation in the battery usage function of Windows 10, that is, it does not display the individual power consumption of each application. Users can only Task Manager makes guesses based on CPU and RAM usage.

Therefore, we hope that Microsoft can add such a feature in the future, after all, this is already available on Windows Phone and Android.

3. Comparison of power saving functions:

The editor used a Yoga Pro 2 with Windows 8.1 and Windows 10 dual systems installed to test the power saving capabilities of the two systems.

The two operating systems maintain similar operating status. The only startup items are Microsoft services and the power plans are exactly the same.

The results show that in idle state, Windows 8.1 performs significantly better than Windows 10 Technical Preview, even if the latter turns on the power saving mode. The effect of power saving mode is not obvious, but it does extend the battery life of the device.

Under the load test, the editor ran the Peacekeeper battery test software on the two systems respectively.

The results show that the performance of the two systems is very close, but the performance of Windows 8.1 is still better than that of Windows 10.

4. Conclusion:

The reason why Windows 10’s power saving capability is so poor may be related to the nature of the system.

Since it is still in the testing phase, the system needs to collect data in the background to monitor and analyze system usage, learn user habits, and detect vulnerabilities.

This well explains why Windows 10 consumes so much power in idle state. Therefore, the performance of the official version of Windows 10 should be greatly improved.
