Just 1 step to generate a Windows battery report and easily understand the health status of your laptop battery

In the taskbar of Windows 10 and Windows 11, the battery icon can display the approximate remaining battery life. This time is only based on the current system load and user usage, and does not take into account factors such as battery aging.

If you want to know more about the specific situation of the laptop battery, you can generate a "battery report" in the system. This report will cover various detailed information about the battery, such as manufacturer, design capacity and historical usage data.

Generate a "Battery Report" in Windows

The steps to generate a "Battery Report" in Windows 10 and 11 are simple:

1Use the Windows R shortcut key to open the "Run" dialog box, enter cmd, and then press Ctrl Shift Enter to open the "Command Prompt" with administrator privileges "Character" window.

2Execute the following command:

powercfg /batteryreport /output "%USERPROFILE�sktopbattery_report.html"

Generate Windows Battery Report

3 After the command is executed, the Windows battery report will be saved to the desktop in HTML format.

Next, we introduce how to read and understand this battery report.

Interpreting Windows Battery Report

• The top of the report lists the basic information of the notebook, such as computer name, Windows version, firmware information, platform role, etc.
• "Installed batteries" The installed battery section lists the detailed parameters of the battery, including:

Field	meaning	Remark
MANUFACTURER	manufacturer
SERIAL NUMBER	serial number
CHEMISTRY	Chemical Type	Usually LION lithium-ion battery
DESIGN CAPACITY	Design Capacity	The unit is mWh (milliwatt hour)
FULL CHARGE CAPACITY	Full battery capacity	The unit is mWh (milliwatt hour)
CYCLE COUNT	Cycles	Fully charged→Empty→Recharge, counted as 1 time

In this part, we mainly focus on "design capacity" and "full capacity". Full capacity ÷ Design capacity = Battery health , for example 51786 ÷ 66880 = 77%. If the "full capacity" is much lower than the "design capacity", it means that the battery has been seriously worn out and you need to consider replacing it with a new one.

• The "Recent usage" and "Battery usage" battery usage sections respectively list the power status changes and battery usage in the past 3 days.

Check battery usage

• The "Usage history" usage history section lists the "active usage" and "connected standby" times in the "battery use" and "plugged in" states each week; "Battery capacity history" battery capacity history record section, lists the changes in battery capacity over time, reflecting the degree of battery loss.

View battery capacity history

• The "Battery life estimates" battery life estimate section estimates the approximate battery life in "active use" and "connected standby" states based on the battery's historical usage data.

View battery life estimate

• The last part of the report is an overall battery life estimate based on all battery discharge cycles.

By viewing this detailed "Battery Report", we can have a more comprehensive understanding of the true condition of the notebook battery than relying solely on the battery icon on the taskbar, and it is easier to evaluate whether the battery needs to be replaced with a new one.
