The Battery Health Tool That Microsoft Tucked Away

If your laptop doesn’t last as long on a charge as it used to, Windows has a built‑in way to show you exactly how your battery is performing. It can generate a detailed report that tracks usage, capacity, and overall health.

How to Generate the Report

Open Command Prompt as an administrator and type:

powercfg /batteryreport

This creates an HTML file (usually saved in your user folder) that you can open in your browser.

What the Report Shows

  • Battery details: Manufacturer, design capacity, and current full charge capacity.
  • Usage history: When your device was on battery or plugged in.
  • Capacity changes: How the battery’s maximum charge has declined over time.
  • Life estimates: Predictions of how long your battery should last based on past patterns.

Why It’s Useful

  • Spot battery wear and decide if replacement is needed.
  • Understand charging and usage habits.
  • Plan ahead for longer trips or heavy workloads.

This hidden Windows feature gives you a clear picture of your battery’s health, helping you make smarter decisions about maintenance and replacement.
