coconutBattery

About

coconutBattery is a Mac app that shows live information about the battery quality of your Mac, iPhone and iPad, so you can keep track of your current battery health. The app runs on macOS 12 Monterey or later, and version 4.4 adds support for macOS, iOS and iPadOS 27 along with a fix for sorting in the History Viewer.

The free version covers core battery diagnostics for your devices. The Plus version, sold as a one-time purchase, adds features such as iPhone/iPad battery diagnostics, saving battery health info, battery details in the menu bar, WiFi support for checking devices without a USB connection, a Battery Lifetime Analyzer with temperature, voltage and charge/discharge statistics, an Advanced Viewer with details such as SSD statistics, notifications for low battery levels, and custom HTML printing templates. A free trial is available that lets you start the app 10 times in Plus mode.

coconutBattery is distributed only through coconut-flavour.com rather than the App Store. Its website also offers older versions for earlier macOS and OS X releases, and it explains how to help preserve battery health by avoiding heat and unnecessary fast charging.
