Does your Yaris cigarette lighter drain battery?

[MoneyT8]

My 2007 Yaris drained my car battery after plugging in a cigarette socket splitter. I had to get a jump start on my battery. I had left 3 devices plugged in and left it for at least 4 hours came back and the car wouldn't start

Does the Yaris still charges devices in the cigarette socket even after the car is turned off? I don't think it does because I ran a test where I would leave a device plugged in and the red indicator light was off.

I don't think my Yaris is suppose to be draining the battery with devices plugged into the cigarette socket after the car has been turned off and it's driving me insane. Do you guys understand what I'm asking? Thanks in advance.
