How to Make a Battery Report in Windows 10


Checking the battery estimate on a laptop or tablet is very easy. Just click on the battery icon and you can see the remaining battery percentage and your estimated battery time. However, this estimate of the remaining time solely depends on what you are doing at the time. For example, if the estimated time shows 8 hours, it doesn't mean your laptop will last that long if you start playing games all the time.

So how long is your laptop's actual battery life? To find out, follow these steps:

1. Right-click on the Start menu to open the menu.

2. Select “Command Prompt (Admin)”.

Note: You can select output to any directory. To make things easier, we put them in the C:\ folder.

4. Open File Explorer and navigate to the C:\ directory. You will see a file named “battery_report.html”. Double click to open the file in your default browser eg. Microsoft Edge, Chrome, Opera.

Understanding Battery Report

This report consists of several subsections. The first area is about the parameters of the hardware, OS version, and other file details.

The next section, Installed batteries, provides details about the batteries installed in the computer. This information includes name, manufacturer, chemical, design capacity and full load capacity.

Recent Usage is a very useful section because there are details of time, state (active or suspended), power source and remaining battery capacity. In short, this is a record when the laptop sleeps, is active, or is being charged with electricity along with the MWh capacity. You can also see the Battery usage graph below this area.

Usage history and Battery capacity history can be used to check battery health. You can see if the Li-Ion battery deteriorates over time.

Battery life estimates are the most important part. Here you can see the prediction of your computer's remaining battery with normal use. This report tends to be more accurate than the estimated time from clicking on the battery icon.
