Create Battery Notifier for Laptop using Python

 

Laptop or P.C battery charging is always a tension. We often forget to charge our laptop and seem to check the battery. This article demonstrates how to create a simple Battery Notifier application using Python. A battery notifier is a simple application that produces a notification message in the form of a pop-up message on the desktop.  With Python, we can do so with the help of psutil library and plyer library.

Modules needed

• psutil(python system and process utilities): It is a cross-platform for retrieving information on running processes and system utilization in python

pip install psutil

• plyer: Plyer module is used to access the features of the hardware. This module does not comes built-in with Python. We need to install it externally. To install this module type the below command in the terminal.

pip install plyer

Approach:
Step 1) Import the notification class from the plyer module
from plyer import notification
Step 2) After that you just need to call the notify method of this class.
Syntax: notify(title=”, message=”, app_name=”, app_icon=”, timeout=10, ticker=”, toast=False)
Parameters:
title (str) – Title of the notification
message (str) – Message of the notification
app_name (str) – Name of the app launching this notification
app_icon (str) – Icon to be displayed along with the message
timeout (int) – time to display the message for, defaults to 10
ticker (str) – text to display on status bar as the notification arrives
toast (bool) – simple Android message instead of full notification
Step 3) Add the sleep function to show that notification again.

CODE
import psutil 
from plyer import notification 
import time 


battery = psutil.sensors_battery() 

while(True): 
	percent = battery.percent 
	
	notification.notify( 
		title="Battery Percentage", 
		message=str(percent)+"% Battery remaining", 
		timeout=10
	) 
	time.sleep(60*60) 
	
	continue
