How to generate a Windows battery report on your Samsung laptop

The battery report is created by a built-in Windows tool called powercfg.
It works on most Samsung notebook series, including Galaxy Book,
Galaxy Book Pro, Galaxy Book Flex, Notebook 9,
Notebook 7, ATIV Book and others.
Here are a few common ways to generate it:

Method 1 – Command Prompt (recommended)

1. Press Windows key, type cmd.
2. Right-click Command Prompt and choose Run as administrator.
3. In the black window, paste this command and press Enter:

powercfg /batteryreport /output "%USERPROFILE%\Desktop\battery-report.html"

After a few seconds, Windows will create a file called
battery-report.html on your desktop.

Method 2 – PowerShell or Windows Terminal

1. Press Windows key, type PowerShell (or Windows Terminal).
2. Right-click and choose Run as administrator.
3. Run the same command:

powercfg /batteryreport /output "%USERPROFILE%\Desktop\battery-report.html"

This does exactly the same thing as Method 1, just in a different shell.

Method 3 – Create a reusable shortcut (optional)

If you check battery health frequently on your Samsung laptop, you can create a small script:

1. Create a new text file on your desktop and name it for example samsung-battery-report.cmd.
2. Edit it and put this single line inside:

powercfg /batteryreport /output "%USERPROFILE%\Desktop\battery-report.html"

3. Save the file and double-click it whenever you want to refresh the report.

Every time you run it, Windows will overwrite battery-report.html with the latest data.

Common Samsung laptop battery problems this tool can help you understand

The Windows battery report contains detailed information such as
Design capacity, Full charge capacity and sometimes
Cycle count. By comparing these values, you can understand many typical
battery issues on Samsung laptops:

• Battery drains quickly on Samsung Galaxy Book / Notebook series –
  If full charge capacity has dropped far below design capacity (for example < 60%),
  your Samsung laptop will run out of power much faster than when it was new.
• Samsung laptop shuts down suddenly at 20–30% –
  A heavily worn battery can no longer provide stable power at low charge levels,
  causing sudden shutdowns or black screens when unplugged.
• Battery stuck at 60–80% (or not charging to 100%) –
  Sometimes this is due to battery protection or eco settings; in other cases,
  the real full charge capacity has already decreased significantly.
• “Plugged in, not charging” on Samsung –
  This may be related to the AC adapter, USB-C / DC-in port, firmware or power profiles.
  However, if the battery is very old or has a high cycle count,
  it can also fail to accept charge properly.
• Battery not detected on a Samsung laptop –
  If Windows does not see the battery at all, it may be a serious battery or mainboard issue
  and replacement is usually required.
• High cycle count (many charge cycles) –
  Many Samsung batteries are designed for roughly a few hundred full charge cycles.
  If your cycle count is very high, noticeable wear is expected.
• Battery swelling (bulging bottom case, lifted touchpad / keyboard) –
  This is a safety issue. If you see any physical swelling on your Samsung battery,
  stop using it and replace it immediately.

Our online checker reads the key values from your Windows report and gives you
a simple health estimate specifically for your Samsung laptop,
so you can decide whether it is time to replace the battery.

How to understand your Samsung battery result

The tool compares Full charge capacity with Design capacity
and calculates an approximate health percentage:

• 80–100% – Good: Your Samsung battery is in good condition.
  For everyday work, study or light entertainment, you can continue using it without urgent replacement.
• 60–79% – Aging: Noticeable wear. If your Samsung laptop runtime is already too short
  for meetings, travel or daily use away from the socket, a new battery will bring a clear improvement.
• Below 60% – Poor: The battery is heavily degraded.
  We generally recommend replacing it to avoid sudden shutdowns and to restore normal runtime when unplugged.

This percentage is an estimate based on the information Windows provides.
Different Samsung models and usage patterns may behave slightly differently,
but it is a very useful starting point when deciding whether to buy a new battery.

Next steps if your Samsung laptop battery is in poor condition

If the health percentage is low, or if you already experience sudden shutdowns,
short runtime, or charging problems on your Samsung laptop, a replacement battery
is usually the most effective solution.

When you look for a new Samsung battery, pay attention to:

• Exact Samsung laptop model (for example: Galaxy Book, Galaxy Book Pro, Galaxy Book Flex, Notebook 9, Notebook 7, ATIV Book, etc.).
• Original battery part number printed on the old battery label.
• Voltage (V) and capacity (Wh or mAh) that match your original battery specifications.
• Reliable supplier, clear warranty and return policy.

If you need help finding the right replacement battery for your Samsung laptop model,
you can contact us with your model name and (if possible) a clear photo of the original battery label.
