 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. A recent stable Magisk version is recommended. 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.
