I bought the car back in 2018. A month back, I couldn't start my car with the battery came w/ the SUV on a cold day. voltage read between 12.1-12.3v. Then I got the battery replaced via in-warranty service. Today I check the battery voltage without starting the car (today is cold, 22F) before heading out (I dont want to be stucked outside at sub-freezing temp), its reading 12.3v. I am charging it up right now w/ a charger. From google search, I dont think this is normal voltage for a good AGM battery. anyone seeing similar issue? Is the SUV battery not spec to handle the car electronics? (i use android auto, seat heater, A/C, all the lights on auto, wipers, etc)

Honda uses a Duel-Mode Charging System. They do this to help with gas mileage by cutting the current that the alternator puts out thus less drag on the engine, better fuel mileage.
Maybe this will help.
My 2020 EX-L AWD doesn't get driver that much, we use it for travel mostly. I keep it hooked up to a Deltran Battery Tender when we don't drive it much and wouldn't over charge (just maintain) the battery.
Google Honda Duel-Mode Charging System for more information.
