Battery drainage while parked for a while… any solution?

[Mohs 9]

Just came back to my Grenadier after 20 days. SoC drops from somewhere in the 70ties to 62%. Starts w/o problems. Hey, it is winter here with temperatures well south of 0, so I am quite happy.
My setup: Single battery, utility vehicle w/o alarm.

Today was the worst state of charge result I have had so far.
Car has been sitting for 2 days and left the PWR switch on.
Fridge, 2 x inductive iphone charging mounts and dash cam on.
No phones in the chargers but they still use a fair bit of power.


As usual I turned the key and she started first go.
Glad I chose the factory auxiliary battery option.
Battery warning came up followed by bings and bongs.

State of charge 0% !!!!

yes I occasionally see a 0%SOC on start-up but it always self corrects after a bit.

Very similar for me. Away in the sun for 19 days, the SOC went from mid 80%s to 66%, single battery.
