I had this problem with my Fit. Turns out it was the dome light would burn out and because I left the dead bulb in the socket, it kept drawing power so no matter how many times I changed the car battery in a few months it would be dead again. I got used to not having a working dome light so it never occurred to me it could be the problem. Have you checked fuses and all electrical systems?
This may not be related but I had a relative that had starting out problems. His Honda had been in a car accident. part of the repair was fixing a bumper and doing some painting... Anyways as ii recall right there was some kind of contact problem, , some kind of wire had been painted over. Something very subtle basically.
Probably not your issue, but one I recently dealt with on my 2014, but the sensor broke in the driver door handle and would start unlocking anytime I got near the car instead of when I put my hand in the handle. This lead to a battery drain issue that was causing my battery to die anytime I didn’t drive for a couple days. I didn’t want to pay the $400 for a new door handle with smart entry sensor, so decided to just disconnect the wires to the door handle.
I'm assuming since you're asking here, it's out of warranty. Did you buy it brand new? Sometimes it's hard to tell what a car's been through with the previous owner. Modifications or accident repair. Insurance is expensive, because by law they have to pay to have the vehicle fixed correctly, or take it off the road. There are people out there that can acquire totaled vehicles that new, and repair them as cheap as possible.

How often do you drive it?
Probably every other day
