My experience is the LELink (Bluetooth Low Energy protocol) works with LeafSpy Pro on both iPhones and Android devices. As well it seems to have very low power draw, and I've not had a problem leaving it plugged in on a day-to-day basis. I still unplug it if I'm leaving for a week or so, just in case. The unit is low profile - hardly know it's there.
Also, I avoid keeping LeafSpy running near the car when the LEAF is shut off, as it will keep waking the system up and you can hear relays clicking every few seconds.
