I've been using this for several years now and it's a great app for your battery.
It's a Magisk module. Install it like any other Magisk module and it's better to reboot though not always required for this module.
You can get the latest version and help from Telegram group. The telegram group is very active, with the developer often answering questions.
Forget about the front end app mentioned in Github notes. Those apps are outdated.
Use Termux (not the Play Store version which again is very outdated) . Get it from Github or F-Droid. You can use any other terminal emulator of your choice.
You need to use
subefore running the commands
acc -r g: Full (HTML)
acc -h g: Condensed (plain text)
Some simple commands:
acc: Wizard: gives you an interface to get started.
acc pause resume: Set pause and resume % (e.g.,
acc 80 70), defaults are 75 70.
acc -s mcc=milliamps: Set charging current limit (no value means default)
acc -s mcc=millivolts: Set charging voltage limit (no value means default)
acc -f: Charge once to 100% without restrictions.
I mainly use it for idle charging (see Don't charge the battery but use connected power to run the phone). Also, I configured the voltage supplied to the battery to be low enough not to cause heating, which is a well reported problem with Pixel 6 series (thankfully, it's alleviated on Android 14).
