How can you tell that the discharge was the factor rather than getting too hot? I've had them die from heat before too, that's normal.
Great question - I can't.
I am careful about keeping things out of the sun, not insulating them, cooling them down when necessary and just generally being very conscious about the temperature of the devices. I've been known to toss a phone into the freezer to keep it cool and in the car I often keep my phone in an AC vent so that it is cold.
