About this tag
The powercfg sleepstudy command generates an HTML report that analyzes battery drain during Modern Standby sleep states on Windows 10 and Windows 11 laptops, tablets, and 2-in-1 devices. The report identifies when drain occurred, its severity, and which hardware components, drivers, apps, networking, or background services remained active during sleep. This built-in Windows tool is useful for troubleshooting unexpected battery loss when the device is in sleep mode with the lid closed or screen off. The tag covers intermediate-level guidance on generating and interpreting the powercfg sleepstudy report to pinpoint causes of battery drain during Modern Standby.
