Is your laptop battery draining too fast? Windows has a hidden command that lets you see the true health of your battery — no apps needed!
🔹 Step-by-Step Guide
Step 1: Open Command Prompt as Administrator
Press Windows Key + S, type cmd, right-click Command Prompt and choose Run as Administrator.
Step 2: Generate the Battery Report
powercfg /batteryreport /output "C:\Users\%username%\Downloads\MyBatteryHealth.html"
Hit Enter — Windows will instantly create a full battery report saved in your Downloads folder.
Step 3: Open the Report
Go to Downloads → double-click MyBatteryHealth.html → it opens in your browser.
Inside, you’ll find:
- Design Capacity: the battery’s original full capacity
- Full Charge Capacity: your current real capacity
- Cycle Count: how many charge/discharge cycles completed
If your Full Charge Capacity is much lower than Design Capacity, your battery has worn out.

📊 Battery Health Example
Example from a real report:
| Date | Full Charge Capacity | Design Capacity | Health |
|---|---|---|---|

📚 Summary
- 90–100% → Excellent
- 80–89% → Good (minor wear)
- 60–79% → Fair (noticeable decline)
- <60% → Poor (consider replacement)
Keep your laptop battery healthy — avoid overcharging, use balanced power mode, and unplug once it reaches 100%.
