 description=ACC is an Android software. It's primarily intended for extending battery service life. In a nutshell, this is achieved through limiting charging current, temperature and voltage. Any root solution is supported. The installation is always "systemless", whether or not the system is rooted with Magisk. If you're reading this from Magisk Manager > Downloads, tap here to open the documentation. Once there, if you're lazy, jump to the quick start section.
