Battery draining fast and want to know why. Then Task Manager can shows power usage information for apps and services, and here's how to see this information.

The Windows 10 October 2018 Update also ships with an improved version of Task Manager, which adds two additional columns to the Processes tab that you can use to analyse the power usage for apps and services running on your system.

The new feature uses the processor, graphics, and disk power information to calculate the energy usage, and it'll help you to understand which apps and services use the most power and which one use the least power. So, if you use a laptop or tablet on the go, you know which apps to avoid to optimise 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.

In this Windows 10 guide, we'll show you the steps to get an understanding of the energy impact of running apps and services on your computer.

How to view power usage for apps on Task Manager

To quickly view power usage information for apps and services, use following steps:

1. Right-click the taskbar.
2. Select the Task Manager option.
3. Click on the Processes tab.
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.

How to add power usage views for apps to Task Manager

If you don't see the two new power usage columns, use following steps:

1. Right-click the taskbar.
2. Select the Task Manager option.
3. Click on the Processes tab.
4. Right-click any of the available column headers, and select the Power usage option.
5. Right-click any of the available column headers again, and select the Power usage trend option.

If these options are not available, then you're probably not running the latest version of Windows 10. This feature is available starting with the October 2018 Update and later.
