Create a Sleep Study report on Windows 10

Windows 10 comes with a nice feature called Better sleep Study and which can tell you the energy consumption of your system.

Available on devices that support the feature Modern Standby/Instant Go (State S0). In this article we will look at what is included in this report and how to create it.

Η sleep mode study shows you how well your system slept when it was in hibernation, and how much activity occurred during it duration of this period. While in sleep, the system still does some work, albeit at a lower level frequency. Because the resulting battery drain isn't easily noticeable, Microsoft has included the Sleep Study tool from Windows 8.1 onwards to allow the user to monitor what's going on. This tool has a very low impact on battery life while monitoring battery draining activities.

The Instant Go feature, also known as Connected Standby, is a modern power model that works in close collaboration between software (firmware, drivers, operating system) and System on Chip (“SoC”) hardware to suspend operation.

In modern standby mode, the computer uses the low power S0 model. In this model, the computer has the flexibility to set the default behavior to restrict network activity while in a low-power mode.

The effects of reducing energy consumption from sleep or inactivity states can be seen after you have created a relevant report. This report is called System Power Report and you must be logged in to an Administrator account to proceed to the next steps.

To create the Sleep Study report in Windows 10, do the following:
Step 1: Open a command line with administrative privileges.
Step 2: Type or copy-paste the following command:

powercfg / SleepStudy / output% USERPROFILE% \ Desktop \ sleepstudy.html

This command will generate a new report for the last 3 days.

The next command is the same report but with a set number of DAYS.

powercfg / SleepStudy / output% USERPROFILE% \ Desktop \ sleepstudy.html / Duration DAYS

In the two above commands, the report is written as an html file and is located on your desktop. It is also possible to store the report in an XML file, such as with the following command (report for 3 days):

powercfg / SleepStudy / output% USERPROFILE% \ Desktop \ sleepstudy.xml / XML

Finally, you can specify the number of days and for the XML format, write the following.

powercfg / SleepStudy / output% USERPROFILE% \ Desktop \ sleepstudy.xml / XML / Duration DAYS

The HTML page with the results of Sleep Study HTML is designed so you can easily read it and interpret it. See below from our own computer,

Note: You can run in the command line the command “powercfg /sleepstudy/?” to see additional powercfg options.
