Battery full notification

Question

I am using a Linux distribution, I didn't get any notification even after the battery is full.

Is there any custom script to run battery charge status and output a sound notification when the battery is fully charged?

Answer 1

I have written a small script that will do that:

---

Script:

#!/usr/bin/env bash
while true
do
    export DISPLAY=:0.0
    battery_percent=$(acpi -b | grep -P -o '[0-9]+(?=%)')
    if on_ac_power; then
        if [ "$battery_percent" -gt 95 ]; then
            notify-send -i "$PWD/batteryfull.png" "Battery full." "Level: ${battery_percent}% "
        fi
    fi
    sleep 300 # (5 minutes)
done

---

Installation:

Run:

sudo apt-get install acpi
git clone https://github.com/hg8/battery-full-notification.git
cd battery-full-notification/
chmod +x batteryfull.sh

Copy the script to ~/bin folder:

cp batteryfull.* ~/bin

Or copy it to /usr/local/bin if you want it to be available for all users on your computer:

cp batteryfull.* /usr/local/bin

Then add batteryfull.sh script as a startup application by:

• Open Dash
• Search for Startup Applications
• Double-click the icon

• Click Add and fill in as follows:

If you're using KDE SC as desktop environment, just do this:

• Open System Settings
• Go to Application and System Notifications (Section: Common Appearance and Behavior)
• If not already selected, choose Manage Notifications from the list on the left side
• Select Power Management System from the Event source drop-down menu
• Click on the list entry Charge Complete
• Select any kind of notification/sound:
• Click Apply

You can write a custom script that checks /proc/acpi/battery/BAT0/state and gives you the feedback on the line charging state: changing to charged. On newer systems you should use /sys/class/power_supply/BAT0/status if available.

You only would need to check every minute or so, but since you want to know what the previous state was (so it won't beep every minute while it is full), you need to keep the previous state in a file to compare if you start the checking program from crontab, or run a long time process that checks every minute and keeps the previous state internally.

If you have multiple battery bays, you should have multiple entries under /proc/acpi/battery (but not under /sys/class/power_supply/BAT*) . If one of those entries has no state, the battery is not inserted (you can also check the file info for the value present)

In case you are using KDE / Manjaro KDE like me. It can be configured in system settings. I enabled to start charging at 20% (search for the depth of discharge to know the reason why it is ideal to charge some batteries at 20%) and stop charging at 80%.

This Works in KDE 5

Installation:

Run:

sudo apt-get install acpi
git clone https://github.com/jruedaq/battery-full-notification-KDE5.git
cd battery-full-notification-KDE5/
chmod +x install
./install
