Advanced Charging Controller (ACCA)

Advanced Charging Controller (ACCA) is an Android application that gives the user control over the device's charge cycle. Rather than leaving charging behaviour to the stock firmware, the application exposes the cycle itself as something the user configures — when charging begins, when it stops, and under what conditions it resumes.

The stated purpose is full control over that cycle, which places the application in the category of battery-management utilities used to keep a device within a chosen charge range instead of holding it at maximum. This is typically of interest to people who leave a device plugged in for long periods.

The application is Android-only and is distributed under the GPL-3.0-only licence. Utilities of this kind commonly depend on privileged access to the underlying system; the material available here does not state the requirements, so anyone considering it should check the project's own documentation for prerequisites and supported devices.
