How to List Battery Status Across All Macs

Using Kolide, You Can Easily View and Query Mac Battery Status Across Your Fleet.

Introduction

Portable macOS devices such as MacBooks can report diagnostic data about the identity and state of their internal battery. This can include details such as charge cycles, charge percentage, and overall health.

What Mac Battery Status Data Can Kolide Collect?

Kolide's endpoint agent bundles in osquery to performantly collect Mac Battery Status from Macs in your fleet. Once collected, Kolide will parse, clean up, and centrally store this data in Inventory for your team to view, query, or export via API.

Kolide metliciously documents every piece of data returned so you can understand the results.

Mac Battery Status Schema

Note on data collection: Due to a bug in the macOS battery API, occasionally this value will be overwritten with NULL

max_capacity Integer

The battery's actual capacity when it is fully charged in mAh

minutes_to_full_charge Integer

The number of minutes until the battery is fully charged.

Special Values:

  • -1 - The system is currently calculating the value
minutes_until_empty Integer

  • Battery Power - Indicates that the battery is drawing internal power
  • Off Line - Indicates the battery is off-line or no longer connected
voltage Integer

The battery's current voltage in mV

collected_at Timestamp

Time the row of data was first collected in the database

updated_at Timestamp

Time the row of data was last changed in the database

What Can You Do With This Information?

Kolide enables you to write your own queries against the data the agent collects. This allows you to build your own reports and API endpoints. For example, you can:

Look for Mac batteries whose health check reports needed service
Kolide SQL
SELECT 
    device_name, 
    model AS battery_model, 
    health, 
    serial AS battery_serial, 
    cycle_count 
FROM mac_batteries 
WHERE health != 'Good'
Example Results

Check Battery 418 georges-macbook bq20z451 F5D80135MBWGQT7AC

Why Should I Collect Mac Battery Status?

This information is collected to determine batteries which are potentially in need of service or likely due for replacement. Serial numbers are also cataloged for administrators to cross reference with Apple recall notices.

End-User Privacy Consideration

Kolide practices Honest Security. We believe that data should be collected from end-user devices transparently and with privacy in mind.

When you use Kolide to list Mac Battery Status data from end-user devices, Kolide gives the people using those devices insight into exactly what data is collected, the privacy implications, and who on the IT team can see the data. This all happens in our end-user privacy center which can be accessed by employees through Slack or Google Workspace account.
