Windows 8 and 10 both include a hidden “Battery Report” feature. Generate a report to see health information about your battery, how its capacity has decreased over time, and other interesting statistics.
This battery reporting feature is built into the powercfg command, so you’ll have to pop into Command Prompt or PowerShell to run the command. We’ll be using PowerShell in this tutorial, but either works just fine. You can also use powercfg to generate an energy report, which gives you recommendations for ways you can reduce your computer’s energy usage and extend its battery life.
Generate a Battery Report
The actual battery report you’ll be generating is an easy-to-understand web page file. You just have to run a single command to create it.
First, open a PowerShell window. Press Windows+X and choose “PowerShell” from the Power User menu.
