How long would it take a water bottle in your bag to freeze on your back in -30C degree weather? That may give you a baseline to work from.

  Water has huge thermal inertia. Laptops don't. They may freeze quite quickly. Something to bear in mind for the future.

    I've found iPhones get real wonky <-5C. I think the safe storage temp is like -20C because it can damage the battery.

      No shit, I attempted GPS-navigating Oslo using my phone this winter, had to go back to actually talking to unknown people.
