CoconutBattery

coconutBattery is a 3rd-party utility for Mac OS X (now macOS) developed by coconut-flavour [sic] to monitor the battery health of Apple devices with a battery.

Usage
The utility reports information about age of the mobile device and its battery, battery health, cycle counts, temperature, and any other saved history.

History
coconutBattery was created in 2005 by Christoph Sinai, then a 22-year-old student in Germany. After some legal issues, it had reached version 2.0 on December 9, 2005. In March 2015, version 3.2 added support for connected iPads, iPhones, and iPod touches (older non-iOS iPods are not supported). A premium version with additional features, coconutBattery Plus, is available for 9.95.
