Microsoft's Windows 11 operating system will celebrate its one-year anniversary in October this year.

A few days ago, Microsoft has released this year's major update Windows 11 22H2 version, which improves system stability and brings some upgraded features, such as: the taskbar supports the "drag and drop" function.

Although Microsoft has vigorously promoted the upgrade of the Windows 11 system, and is expected to officially withdraw Windows 10 in October 2025.

However, there are still a large number of users who stick to the old version of the Windows 10 system.

After the Windows 11 system is updated to the 22H2 version, in addition to better stable performance, has the battery life also improved?

In this regard, the foreign media Neowin actually uses the 21H2 version of Windows 10, the 22H2 update version of Windows 11, as well as Windows 11 21H2, and the latest developer version of Windows 11 to measure the battery life of these four different versions.

Please read on...

Using a 14-inch HP laptop as the test benchmark, with the above system versions installed and no other third-party software installed, the PCMark10 Extended system test tool is used to simulate the actual situation of daily use of ordinary computers, such as: video conferencing, Browsers, office application software, photo video editing and games, etc.

The 21H2 version of the Win10 system has a power endurance of up to 3 hours and 12 minutes under the simulation of general daily use, which is better than that of the Win11 system.

The measured results show that the 21H2 version of Windows 10 can last up to 3 hours and 12 minutes, followed by the latest developer version of Windows 11 with a battery life of 3 hours and 3 minutes, and then the Windows 11 22H2 version of 3 hours and 2 minutes. Last year The Windows 11 21H2 version was last at 2 hours and 54 minutes.

However, the battery life gap between the four system versions is not too large.

The 21H2 version of the Win10 system, in the test project of playing high-quality YouTube videos, has a battery life of up to 5 hours and 24 minutes, which is better than the Win11 system.

In addition, when using the Edge browser to play YouTube high-definition 1080p videos, in this test project, among the four tested system versions, the 21H2 version of Windows 10 also has the best battery life, and the power can be played for up to 5 hours and 24 minutes, nearly 30 minutes more than the 22H2 version of Windows 11.

As for the worst battery life, the Windows 11 22H2 version has a power playback time of 4 hours and 50 minutes.
