My brand new bike is losing 2-5psi per day in the tires. Is this normal or should I be concerned?

I’ve been monitoring it for a few days. I carry a small portable air compressor and the digital gauge on it consistently shows the pressure being around 2-5 psi lower.

It seems the front tire loses air slightly faster than the rear but I can’t confirm that yet.

It seems I have to top up both tires before every ride now. I do around 80-150km per ride and measure inside a my garage before riding.

Should I be concerned? Is this normal? What has been your experience? Put my mind at ease one way or another 🤪 I just want to ride safely.
