How to view the power usage for apps with Task Manager

Alongside the vast aray of improvements and new features, the Windows 10 October 2018 Update (version 1809) also ships with a much improved version of Task Manager, which adds two additional columns to the “Processes” tab that you can use to analyze the power usage for all the apps and services running on your PC.

The new feature uses the processor, graphics, and disk power information to calculate the energy impact, and it will help you to understand which apps and services use the most power versus those that use the least power. So, if you use a laptop or tablet on the go, you know which apps to avoid to optimize the battery life. Or if you’re noticing that your battery is draining faster than usual, this information can give you an idea of which app is causing the problem.

Even with a Desktop PC this new and improved Task Manager can quickly tell you which process are causing the biggest impact on the computers performance.

To open Task Manager right click the Taskbar and select the Task Manager option. When it opens click on the Processes Tab (this may already be open).

While in the Processes tab, you’ll notice two new columns, including “Power usage” and “Power usage trend.”

Using the “Power usage” column, you can see the power an app or service is drawing in real-time.

Then using the “Power usage trend” column, you can also see the power usage of apps and services, but as a trend over two minutes. (When you first start the app, it’ll take two minutes to populate the information.)
