From 24f11c6221609166d196e314904df24bf87d99c1 Mon Sep 17 00:00:00 2001
From: VR-25 <28943176+VR-25@users.noreply.github.com>
Date: Sat, 4 Apr 2020 22:04:33 +0100
Subject: [PATCH] **2020.4.4-dev (202004040)** - acc -(e|d): do not do
 unnecessary work - acc -f: fixed capacity limit bypass - acc -F: general
 fixes and optimizations - accs: acc foreground service, works exactly as
 accd, but remains attached to the terminal - "acc -t --" is now "acc -t" -
 ACC/service trigger vibrations on certain events (charging enabled/disabled,
 errors, auto-shutdown warnings and acc -C 100% reached); vibration patterns
 are customizable - Auto-reset broken/invalid config - Enhanced acc -C
 compatibility - Fixed busybox setup issues on devices not rooted with Magisk
 - Misc fixes - Major optimizations - Updated documentation

+> I don't really understand what the "-f|--force|--full [capacity]" is meant for.
+
+Consider the following situation:
+
+You're almost late for an important event.
+You recall that I stole your power bank and sold it on Ebay.
+You need your phone and a good battery backup.
+The event will take the whole day and you won't have access to an external power supply in the middle of nowhere.
+You need your battery charged fast and as much as possible.
+However, you don't want to modify ACC config nor manually stop/restart the daemon.
+
+
+> What's DJS?
+
+It's a standalone program: Daily Job Scheduler.
+As the name suggests, it's meant for scheduling "jobs" - in this context, acc profiles/settings.
+Underneath, it runs commands/scripts at specified times - either once, daily and/or on boot.
+
+
+> Do I have to install/upgrade both ACC and AccA?
+
+To really get out of this dilemma, you have to understand what ACC and AccA essentially are.
+
+ACC is a Android program that controls charging.
+It can be installed as an app (e.g., AccA) module, Magisk module or standalone software. Its installer determines the installation path/variant. The user is given the power to override that.
+A plain text file holds the program's configuration. It can be edited with any root text editor.
+ACC has a command line interface (CLI) - which in essence is a set of Application Programing Interfaces (APIs). The main purpose of a CLI/API is making difficult tasks ordinary.
+
+AccA is a graphical user interface (GUI) for the ACC command line. The main purpose of a GUI is making ordinary tasks simpler.
+AccA ships with a version of ACC that is automatically installed when the app is first launched.
+
+That said, it should be pretty obvious that ACC is like a fully autonomous car that also happens to have a steering wheel and other controls for a regular driver to hit a tree.
+Think of AccA as a robotic driver that often prefers hitting people over trees.
+Due to extenuating circumstances, that robot is not upgraded as frequently as the car.
+Upgrading the car regularly, makes the driver happier - even though I doubt it has any emotion to speak of.
+
+
+> Does acc work also when Android is off?
+
+No.

 - Charging switch tests take  significantly longer (switch_delay=18); this leads to more consistent results

 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.
