BatteryOptimizer for MAC is a simple Command Line Interface (CLI) tool that functions similarly to AlDente, allowing users to set battery charge limits and schedule battery calibration for MacBooks. The key difference is that this tool is entirely free and open-source.
One of the standout features of BatteryOptimizer for MAC is its lightweight design. It not only provides functionalities comparable to AlDente and coconutBattery but does so with significantly lower memory usage, approximately 1/20th that of AlDente and 1/30th that of coconutBattery.
This tool is a fork of the original battery utility, incorporating numerous new features and enhancements. It supports both Apple and Intel CPU Macs, and includes a sail mode that allows the battery to maintain a target percentage without charging.
Users can also schedule automatic calibration on specific days each month or on a recurring basis, enhancing usability. Notably, the charging limiter remains functional even when the MacBook is asleep or powered down.
For Intel CPU Macs, the charge limit can be set at a maintenance percentage, while Apple CPU Macs have a fixed limit of 80%. Additional features include a daily battery log, notifications for calibration steps, reminders to open the MacBook lid before calibration, and alerts for software updates.
For Intel Macs, the charge limit works across all models, but discharge and calibration features are only effective for models from 2014 or earlier. Efforts are ongoing to find a discharge method for newer Intel models.
The installation and usage details can be found on the GitHub page. BatteryOptimizer for MAC is free, but support to enhance its functionality is always appreciated.
