    How much does the battery get depleted sitting in the car and listening to music with the air conditioning on and my phone plugged in getting charged? Is the depletion obvious?

    Not a lot, and not really. I'd expect something around 1 RM/hr, maybe 2, mostly from the AC. The draw from USB is negligible. I'm not sure about the stereo, but its fuse seems to be rated 20A.

    I did an experiment and you would lose about 5 rated miles per hour for running A/C while your car is stationary.:

    As mblakele indicated, I think additional energy consumption from other accessories like lights, stereos, cell phone... would be negligible comparing to A/C.

    Lost 4 rated miles in an hour sitting in 93 degrees with A/C on 72 last weekend in Enchanted Rock, Texas. Tarmac was probably 100++ based on what the hiking felt like. Also had radio on and charging phone.

    12v accessory power is negligible. Like we're talking miliwatt range, nowhere close to even 1 Kwh.

    A/C on the other hand, i hung out in my car for ~2 hours outside waiting for someone and lost 3 rated miles.

    USB charging is 5W, so you'd need to charge a phone for 60 hours to use 300W, which is about 1 rated mile.
    The aircon is probably about 1000W (depending on inside/outside temp gradient), so about 3 miles per hour.

    Check Bjorn Nyland's awesome videos on youtube. He has a lot of info about how much you use by staying in the car - both warm and cold weather.

    How much the AC has to work depends on the outside temp and what you have it set to. In typical Los Angeles heat, my car usually uses about 1.5-2 kW when not driving but it's still on. There is is about 70-90 kWh of usable energy in the Model S (depending on battery size). That roughly gives you between 35 to 60 hours before the battery is down.
