Track Power Usage & monitor Trend in Task Manager of Windows 10

One of the small, but crucial changes Windows 10 v1809 has rolled is the ability to track power usage of UWP Apps, and processes. This option is available via the Task Manager, just like GPU usage, which shows which apps consume more power, and the trend in general.

Earlier the main memory column in the Task Manager Processes tab used to show memory used by suspended UWP process. This is not available anymore. Under the new model of memory management, OS can reclaim memory used by these suspended UWP process when needed. The claimed memory can then be used somewhere else when needed by other processes. Hence they have been cut out from memory usage calculation to reflect actual memory usage.

However, the details tab will still show a comparison for the users to make a comparison. The new additions include two power usage colors. First displays the actual power usage, while the second column displays power usage trend over a period of time. This will help customers understand which apps and services are using more energy. The interesting part is that Power usage metrics are calculated based on GPU, CPU and Disk usage. This is very useful when for Laptops which run on battery.

The power usage trend column is continuously updated. The trend is based on usage for over two minutes of each app and services. This is usually blank when it starts and populates over the time. So, it’s almost real-time, and can also help developers know if their apps are consuming more power.

While this is available by default, if you cannot see it in the Task Manager, follow the steps:

  • Right-click on the taskbar, and select Task Manager to launch it.
  • Then again right click on any of the columns headers.
  • Select Power Usage and Power Usage Trend.

You should see value from very low to very high for both the columns instead of showing percentage.

Do note that Windows 10 only reclaims memory from suspended UWP Apps only, and not other apps. So if you are not using any UWP Apps, whatever memory consumption you see in the task manager is accurate.
