There’s considerable concern about battery life in laptops still to this day during 2015. Usually when updating software like you would during a major operating system upgrade, the battery life can get considerably worse. We know this happens frequently with our mobile devices like the iPhone battery draining concerns  that arrive after a major iOS release.
The battery report in Windows 10 is useful for people who are running Windows 10 from a tablet or laptop environments. It holds little value to those on a desktop PC that doesn’t use a battery.
HOW TO CREATE A BATTERY REPORT IN WINDOWS 10

– alternatively, you may use the hotkey combo ‘WinKey+X’.

– make sure you choose to run it as the Admin.

4. Type the first command: “powercfg /batteryreport /output “C:\battery_report.html”.

7. The battery report file should be easy to see. It’s not hidden in any folder. Just look for the .html file from the main page.
8. You can open the battery report with any web browser. Those loyal to Windows 10 will be pleased to know you can open it in Microsoft’s Edge browser, just like you can with Chrome, IE Firefox, and any other browser.
9. The report states your battery details like capacity, manufacturer, chemistry and so forth.
10. The recent usage tab shows you the times the laptop was awake, went to sleep and what the power consumption was during those times. The recent usage section is best for keeping close tabs on monitoring the battery and checking if the battery is waking when it is meant to be sleeping.
11. You also get a battery usage chart that shows a graph of the battery usage over a 3 day period. After observing your batteries last three days, you get a good idea of the overall health of the battery.
