Set Charge Current

A simple C program to set the charging current for your device by modifying the constant_charge_current_max value in the sysfs directory. Ideal for rooted Android devices or Linux systems where manual tuning of charge current is needed.

Features

• Set charging current dynamically (in milliamps).
• Automatically manages file permissions for safe writes.
• Compatible with Android (Termux) and standard Linux.
• Includes Makefile with install, uninstall, info, and run targets.

Requirements

• Root Access — Required to modify sysfs charging parameters.
• Linux or Android — Works on rooted Android (via Termux) or any Linux-based system.

Installation

git clone https://github.com/DX4GREY/set-charge-current.git
cd set-charge-current
make

Optional: Install binary system-wide

make install

This will detect your OS and install to the correct location:

• Android (Termux): ~/../usr/bin
• Linux: /usr/local/bin

Optional: Create magisk module.

 make magisk_module

Select a predefined Magisk module template to create a custom module for Android devices. This allows seamless integration with Magisk for managing charging current settings.

Usage

sudo ./setcurrent <current_in_mA>

Example:

sudo ./setcurrent 2000  # Sets charging current to 2000 mA (2A)

Help

./setcurrent help

Uninstall

make uninstall

Clean up build files

make clean

Troubleshooting

• Permission Denied: Make sure to run the binary as root (sudo) and ensure your device allows sysfs writes.
• Invalid Argument: Your hardware might not support the value you're trying to set. Try lower values like 1000, 1500, etc.
