How to Get MacBook Pro Battery Health Using PowerShell?

Are you concerned about the battery health of your MacBook Pro but unsure how to check it efficiently? There is a reliable way to get detailed battery information using PowerShell.

In this tutorial, I will explain easy-to-follow methods to retrieve your MacBook Pro battery health data using PowerShell.

Method 1: Using PowerShell on macOS to Query Battery Health

First, ensure you have PowerShell 7 or later installed on your MacBook Pro. You can download it from the official Microsoft repository.

Once installed, you can use macOS system commands within PowerShell to retrieve battery info. The pmset command is built into macOS and provides battery status and health data.

Follow the steps below:

1. Open PowerShell on your MacBook Pro.
2. Run the following command to get battery status:

pmset -g batt

This command queries your Mac’s battery status, including charge percentage and whether it’s charging.

You can see the exact output in the screenshot below:

3. For detailed battery health information, use:

ioreg -l | grep Capacity

Or in PowerShell syntax:

ioreg -l | Select-String "Capacity"

This retrieves raw data about your battery’s maximum and current capacity, which helps determine health.

pmset and ioreg are native macOS utilities that expose battery metrics. By running them inside PowerShell, you combine the power of macOS system commands with PowerShell’s scripting capabilities, making it easier to automate and parse the results.

Method 2: Generating a Battery Report Using Windows PowerShell (For Boot Camp or Virtual Machines)

If you run Windows on your MacBook Pro via Boot Camp or a VM, you can use Windows PowerShell’s built-in powercfg utility to generate a comprehensive battery report.

1. Open PowerShell with Administrator privileges.
2. Execute the following command:

powercfg /batteryreport /output "$env:USERPROFILE\Desktop\batteryreport.html"

3. Navigate to your desktop and open batteryreport.html in your browser.

Method 3: Using PowerShell Scripts to Monitor Battery Health Over Time

For IT professionals managing multiple MacBook Pros, scripting battery health checks can save time.

Here’s a simple PowerShell script snippet that runs the macOS pmset command and outputs battery percentage:

$battOutput = pmset -g batt
$battOutput | ForEach-Object {
    if ($_ -match '(\d+)%') {
        Write-Output "Battery Charge: $($matches[1])%"
    }
}

• This script captures the battery status output.
• It uses regex to extract the current battery percentage.
• You can extend this script to log data regularly or trigger alerts when battery health drops.

You can see the exact output in the screenshot below:
