The GoPro 7 is doing a lot of work when it's turned on, so the expected battery drop should be about 1.35% every minute. This will vary depending on how the camera is set up, what format it is recording in and what functions are active (GPS, WiFi, EIS etc).
The battery may need to be charged a number of times before it's calibrated fully.
Can you post a picture of the "lines" you are seeing in the display? It's more than likely these are being caused by the HZ refresh rate of your camera capture matching the refresh rate of the lights inside the house.
