Hey guys, I've got an iPad mini Retina plugged into my car semi-permanently. Here's the problem: The iPad's battery can be at 50% when I turn off my car and then when I go into my car 24 hours later, the iPad is totally dead and the big battery symbol is displayed that the iPad is discharged and needs charge. Don't understand how that's possible, considering the iPad should be good for upwards of 30 days on standby. FURTHERMORE, when I turn my car off, I also turn the iPad completely off. But I've found that when I get back into my car, the iPad turns on as though just the display was asleep. That's led me to suspect that I think my car, with all of its enormous amounts of electronics and programming, maybe the car powers on its own electronics at set intervals (say every few hours) to just run a systems check and check the status of the car, and when it does that it's providing power to the cigarette lighter for a split second and the iPad receives that signal and powers on (since the iPad will always power on automatically if it's off when you plug it in to charge). So that would explain why the iPad's battery would be slightly lower when I return to the car (since my car turns the iPad back on), but does not at all explain the enormous power drain and the fact that it can lose 50% charge in less than 24 hours while the iPad is sleeping. On top of that, the iPad seems to be draining my car battery quite a bit. One time I started it up for the first time in 4 days and a message on the dash popped up and said "Low Battery Protection Active - Power Sockets Deactivated." So somehow the iPad is rapidly discharging itself and my car is trying to charge it back up, but the iPad is discharging itself at a rate more rapid than my car can sustain and the process continues until my car senses low voltage and disables the power socket that the iPad is plugged into in order to preserve the battery and allow the car to still start. How it's connected: Apple's Lightning to 30-pin adaptor > 30-pin adaptor to Kensington USB and line-out audio. And I have the USB plugged into a USB cigarette outlet adaptor and the line-out cable plugged into my car's AUX port. Does anyone have any theories as to what would be causing the iPad to rapidly drain its battery? Is it possible that since the audio cable is also plugged in via line-out that somehow that is causing a constant drain that would be equivalent to if it were playing music the whole time, even though no music is being played?
