One of the XDA-Developers forum members created the Notch Pie application, which will make a teardrop-shaped cutout on the screen
How it works
Everything is very simple. Open the application, adjust the location and the indicator streamlined under the cutout of your device. Next, choose the thickness. After that, around the "droplets" will display the battery charge level. It works on all devices with a drop-shaped notch without root-rights and “dances with a tambourine.” How it looks can be seen in the images below:
