Create a Sleep Study report on Windows 10

Windows 10 comes with a nice feature called Sleep Study that can tell you the power consumption of your system.

Available at Appliances that support the operation Modern Standby/Instant Go (Status S0). In this article we will see what is included in this report and how to create it.

Η sleep mode study shows you how well your system was sleeping when it was suspended, and how much activity it displayed during that time. While in sleep mode, the system still does some work, albeit at a lower frequency. Because the resulting battery power consumption is not easily understood, Microsoft has included the Sleep Study tool from Windows 8.1 onwards to allow the user to monitor what is happening. This tool has a very low impact on battery life while keeping track of battery consumption 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 the modern waiting method, the computer χρησιμοποιεί το μοντέλο χαμηλής ισχύος S0. Στο μοντέλο αυτό ο υπολογιστής έχει την ευελιξία να ρυθμίσει την προεπιλεγμένη συμπεριφορά για να περιορίσει τη δραστηριότητα δικτύου ενώ βρίσκεται σε κατάσταση χαμηλής κατανάλωσης ενέργειας.

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 the command "powercfg / sleepstudy /?" At the command prompt to see additional powercfg options.
