 # Get-BatteryStatus.ps1
 
 ## Overview
-**Get-BatteryStatus.ps1** is a PowerShell script for Windows 10/11 that displays your laptop's battery percentage and charging status. The script uses the .NET `System.Windows.Forms` library to access battery information and provides a color-coded status output for quick visual feedback.
-
-## Features
-- **Battery Detection:** Checks if a battery is present on the system.
-- **Battery Percentage:** Displays the current battery level as a percentage.
-- **Charging Status:** Shows whether the device is plugged in or running on battery.
-- **Color-Coded Output:** Uses different colors for different battery levels:
-  - **Green:** 80% and above
-  - **Blue:** 50% to 79%
-  - **Yellow:** 20% to 49%
-  - **Red:** Below 20% or if no battery detected
+**Get-BatteryStatus.ps1** is a PowerShell script for Windows 10/11 that prints a **structured battery analysis report directly in the console**.
+
+It provides a clear, technician-readable summary of battery health, real-world consumption and runtime estimates — without having to open an HTML file.  
+All data is sourced from a single **`powercfg /batteryreport`** HTML file generated temporarily at runtime.
+
+## What it shows
+
+### Machine identity
+- Computer name (from `$env`)
+- Computer model (from `SYSTEM PRODUCT NAME` in the powercfg report)
+- CPU name (via `Win32_Processor`)
+
+### Battery information
+- **Design capacity** *(factory/original maximum)* in **Wh**
+- **Current capacity** *(current maximum)* in **Wh**
+- **Battery health (%)** computed from Design vs Current capacity
+
+### Usage statistics
+- Number of **analyzed discharge sessions** (parsed from the powercfg report)
+- **Average power consumption** in **Watts** across all sessions
+
+### Battery life estimation
+- **Estimated runtime** with the current battery
+- **Estimated runtime** with a new (design capacity) battery
+
+### Conclusion
+- **Wear level (%)** 
+- Potential **runtime gain** from replacing the battery (in minutes)
+
+## Data sources
+All data comes from a single source:
+
+| Data | Source |
+|---|---|
+| Computer name | `$env:COMPUTERNAME` |
+| Computer model | `powercfg /batteryreport` HTML (`SYSTEM PRODUCT NAME`) |
+| Design / Current capacity | `powercfg /batteryreport` HTML (`Installed batteries` table) |
+| Discharge sessions (duration + energy) | `powercfg /batteryreport` HTML (`Battery usage` table) |
+| CPU name | `Win32_Processor` (CIM, single call — not in powercfg report) |
+| Battery presence | `System.Windows.Forms.SystemInformation.PowerStatus` |
+
+The script generates a **temporary** HTML file in `%TEMP%`, parses the needed values, then **deletes it immediately**.
 
 ## Parameters
-This script does **not** take any parameters.
+This script does not take any custom parameters.  
+You can use standard PowerShell common parameters such as:
+- `-Verbose` to see the path of the generated report and any internal diagnostic messages.
 
 ## Usage
 ```powershell
 .\Get-BatteryStatus.ps1
 ```
 
-## Output Example
+Verbose mode (recommended for troubleshooting):
+```powershell
+.\Get-BatteryStatus.ps1 -Verbose
 ```
-Battery Percentage: 95% (Online)
-Battery Percentage: 67% (Offline)
-Battery Percentage: 24% (Offline)
-Battery Percentage: 8% (Offline)
-No battery detected.
+
+## Output example
+```text
+==== BATTERY ANALYSIS REPORT ====
+
+Computer                      : HP EliteBook 840 G8
+CPU                           : Intel Core i5-1135G7
+
+Battery information
+-------------------
+Design Capacity               : 53 Wh
+Current Capacity              : 37 Wh
+Battery Health                : 70 %
+
+Usage statistics
+----------------
+Analyzed sessions             : 34
+Average consumption           : 12 W
+
+Battery life estimation
+-----------------------
+Estimated runtime (current battery)   : 2 h 33 min
+Estimated runtime (new battery)       : 3 h 43 min
+
+Conclusion
+----------
+Battery wear detected         : 24 %
+  Replacing the battery would increase runtime by ~70 minutes.

-## Help & Documentation
+## Help & documentation
 ```powershell

-man .\Get-BatteryStatus.ps1
 ```
 
 ## Troubleshooting
-- **No Battery Detected:** If you run the script on a desktop or a device without a battery, you'll see "No battery detected."
-- **Requires Windows:** The script only works on Windows 10/11 and requires PowerShell 5+.
-- **Color Output:** Colors are visible only in terminals that support colored output.
+
+### "No battery detected"
+You are likely running the script on a desktop, a VM, or a device without a battery.
+
+### "Failed to generate battery report"
+`powercfg` requires elevated privileges on some systems.  
+Try running PowerShell **as Administrator**.
+
+### Capacity shows "N/A"
+The `powercfg /batteryreport` HTML structure may differ on non-English Windows installations.  
+Run with `-Verbose` to confirm the report was generated, then inspect the HTML file manually before it is deleted (add a breakpoint or comment out the `finally` block temporarily).
+
+### No discharge sessions found
+This can happen if the machine has only been used on AC power recently, or if the battery report does not contain any discharge entries for the last 7 days.
+
+## Requirements
+- Windows 10 / 11
+- PowerShell 5.1 or PowerShell 7+
+- `powercfg.exe` available (built-in on all Windows versions)
+- Administrator rights may be required for `powercfg /batteryreport`
