AlDente

AlDente is a macOS application that allows manual management of the maximum charge level of a MacBook's battery. Its main function is to extend the lifespan of lithium-ion batteries by preventing a full 100% charge, keeping the level within a recommended range.

• Charge Limiter. Sets a custom maximum percentage for battery charging. The application writes this value to the MacBook's System Management Controller (SMC), stopping the charge once the configured limit, usually around 80%, is reached.
• Calibration Mode. Performs full charge and discharge cycles to calibrate the battery's measurement system. This process improves the accuracy of the remaining charge percentage indicator and maintains the overall health of the power system.
• Sailing Mode. Allows the battery to charge up to the set limit even when the device is in sleep mode. This feature is designed for extended use while plugged in, maintaining the target charge level.
• Low Power Mode. Activates the system's low power mode when the battery charge falls below a defined threshold. This action conserves energy by reducing performance and background activity.
• High Power Mode. Enables high-performance mode on compatible MacBook models. This setting raises the thermal limit and fan performance for tasks requiring maximum processing power.
• Thermal Protection. Monitors the battery temperature and triggers corrective actions if it exceeds a configurable limit. The system can force a charge pause or reduce power to prevent heat damage.
• Task Scheduler. Schedules automatic changes to the charge limit based on specific days or times of day. Users can configure different charging profiles for weekdays and weekends or for periods of active use and inactivity.
• Graphs & Statistics. Displays historical data on battery behavior, charge cycles, and temperature levels. These graphs provide insight into battery wear and performance over time.
• Menu Bar Customization. Allows modification of the icons and information shown in the macOS menu bar. Users can choose which statistics and controls are visible for quick access.
• Apple Shortcuts. Integration with the Apple Shortcuts app to automate functions via scripts. It allows enabling or disabling modes like charge limiting or calibration mode through system automations.
• Relocatable Dashboard. The main interface displaying the current battery status and primary controls. The window retains its position on the screen after being closed and reopened.
• Dark and Light Mode. Support for macOS system appearance themes. The interface automatically adapts to the dark or light mode selected in system preferences.
• Translations. Interface localized into several languages. The application's text strings are translated to support users in different regions.
• Launch at Login. The application is configured to start automatically during system boot. It ensures that the charge limiting is always active without manual user intervention.

The AlDente application was created by David L. in the year 2020. Development began as a project to solve accelerated battery degradation in MacBooks. The source code is written in the Swift programming language, using native macOS frameworks for the user interface and system interaction. The project was initially published on GitHub under the organization name AppHouseKitchen. Subsequent updates have added additional features and support for new versions of the operating system and Apple hardware.
