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 in devices that support the Modern Standby / Instant Go mode. In this article we will see what is included in this report and how to create it.

Η sleep mode study shows you how correctly it "slept". system when it was suspended, and how much activity occurred during that time. While in "sleep", the system still does some work, albeit at a lower 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.

Η λειτουργία Instant Go, γνωστή και ως Connected Standby, είναι ένα σύγχρονο μοντέλο παροχής ισχύος το οποίο λειτουργεί σε στενή συνεργασία μεταξύ λογισμικού (firmware, προγράμματα οδήγησης, λειτουργικό σύστημα) και hardware with System on Chip (“SoC”), for sleep mode.

In the modern standby method, the computer uses the low-power S0 model. In this model the computer has the flexibility to adjust the default behavior to limit network activity while in a low-power state.

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

At two above commands the report is written as an html file and located on your desktop. It is also possible to save the report to an XML file, for example 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 σελίδα with the results of the Sleep Study HTML is designed so that you can easily read and interpret it. See below from one of our computers,

Note: You can run the command "powercfg / sleepstudy /?" At the command prompt to see additional powercfg options.
