Windows Sleep Study Tool is a new tool from Microsoft that helps you determine exactly what your battery consumes on a computer supported by Windows 10/8.1 InstantGo. InstantGo is, as already mentioned, a new power mode on some Windows 8/8.1/10 devices that allows your system to sleep in the background while updating applications and resuming them if necessary.

A Microsoft blog post explains that your system will continue to operate in standby mode, although at a lower frequency. This exercise consumes energy and battery discharge is not easily noticeable. Windows 8.1 Sleep Study Tool plays a role in this regard. The tool generates a report in the form of an HTML file in which you can see the top five reasons why your device is low on battery power when you need it most.
