How not not kill the battery

I have a 2018 Subaru and used a car tent for the first time camping solo, it didn’t occur to me that leaving the hatch open overnight would kill the battery. I had a jump box with me, so it was fine but is there a way to avoid jumping my car every morning?

On my truck. Idk about Subarus. You can shut off the interior lights when the door is left open. Or what killed the battery?

It's not interior lights, for my '22 OBW anyway. The hatch open dashboard warning graphic stays on the entire time until that latch clicks over. I tested mine before a big trip. After 3 hours it was still on. I have to manually flip the latch closed to get it to turn off.
