I am working on a project where my Pi is always connected to a vehicle to provide its GPS information.
Seeing such a device must be always turned on, I am attempting to tap into a battery line that always has power.
My question is, will this deplete the vehicle's battery overnight? Or in two days if the vehicle hasn't been driven?
Other GPS Units, car alarms are always on 24/7 and that doesn't affect the battery. I left my phone charging overnight in the car and it had no effect on my battery.
Secondly, to use less power, is it wise to remove the LAN chip? Or is that a myth?
