Thanks for the info guys,
I always wonder how my iPhone will last out on the trails, haven’t used it out on the trails yet
My iPhone shuts off when it's in my inner coat pocket when it gets cold, usually around the single digits. Every version I've had has done so (4/5/6/7). If I wear a shirt with pockets so the phone is one thin layer from me, it's usually OK, but pretty useless to see the screen at that point.
Exact same experience here, also with several different generations of iPhones. I’d say at around 15 degrees and below they will shut down within about 30 seconds out of the pocket.
No idea what guys are doing to get better performance out of them in the cold. I’m guessing a hardline from the sled’s electrical system somewhere.
Look at redpinemapping.com they have nice trail mapping and an app for your computer
that you can download the maps to a Garmin nuvi called base camp They cover wisconsin, Minn, UP ,lower Mich and out east US Problem I encountered Garmin is too small and to dim to see in bright daylight while moving. I hooked mine to power to charge battery while running
You can either overlay the trails onto the Garmin street maps or use their entire street and trail maps I liked theirs better
