## Charge Limit

The device supports setting a charge limit by making some ACPI calls (extracted from the Xiaomi PC Manager software). Provided the acpi_call package is installed, the following script makes this easily accessible under Linux as well:

    set_charge_limit.sh

    #!/bin/bash

    acpi_call() {
        local command="$1"
        local hex_value="$2"

        local acpi_string="\\_SB.PC00.WMID.WMAA 0x0 0x1 { \
    0x00 $command 0x00 0x10 0x02 0x00 $hex_value 0x00 \
    0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 \
    0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 \
    0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 }"

        echo "$acpi_string" | tee /proc/acpi/call
    }

    set_charge_limit() {
        local limit_hex
        case "$1" in
            40) limit_hex="0x08" ;;
            50) limit_hex="0x07" ;;
            60) limit_hex="0x06" ;;
            70) limit_hex="0x05" ;;
            80) limit_hex="0x01" ;;
            *) echo "Invalid limit. Valid options: 40, 50, 60, 70, 80"; exit 1 ;;
        esac

        echo "Setting $1% limit"
        acpi_call "0xfb" "$limit_hex"

        echo "Enabling charge limit"
        acpi_call "0xfa" "0x00"

        echo "Enabling charge limit (second call)"
        acpi_call "0xfa" "0x00"
    }

    disable_charge_limit() {
        echo "Disabling charge limit"
        acpi_call "0xfb" "0x00"

        echo "Disabling charge limit (second call)"
        acpi_call "0xfb" "0x00"
    }

    if [ "$#" -ne 1 ]; then
        echo "Usage: $0 <limit|disable>"
        echo "  limit: 40, 50, 60, 70, or 80"
        echo "  disable: turns off charge limiting"
        exit 1
    fi

    if [ "$1" = "disable" ]; then
        disable_charge_limit
    else
        set_charge_limit "$1"
    fi

The script needs to be run on every reboot. You can automate this by using systemd. An example unit to set the charge limit to 70% may look like this:

    [Unit]
    Description=Set battery charge limit on boot

    [Service]
    Type=simple
    ExecStart=/path/to/set_charge_limit.sh 70
    User=root
    Group=root

    [Install]
    WantedBy=multi-user.target
