Nonetheless there still is the issue of days of riding through areas like North Dakota that will have no service whatsoever. Perhaps maps might serve me better in these areas. The issue of overheating that I'm referring to has nothing to do with overuse of phone and all to do with heat generated from the sun. Try putting your phone on a picnic table on a 90 degree sunny day where the sun is shining on it. Within 30 minutes the phone will overheat. This may be an argument for the handlebar bag instead. (Prior tours I've used maps.) And maybe you are correct that I am overestimating the necessity of needing my phone as a directional aide. Thanks.
I used mine in the Mojave and other areas of the Southwest in 110+ F heat. According to the locals it was probably well above 100 F maybe as high as 118 F, but I didn't document the numbers above 110 F. Any way I used it in the manner I described in my other post and don't recall ever having it shut down from the heat.
Also I live in Tallahassee and often ride in 100 F or a little higher sometimes heat and never have a problem with it on the handlebar or more often in a jersey pocket or fanny pack. I suspect that might in part be because it is pretty much never left sitting still in the sun. Also it is never in a bag directly in the sun. It is often in a waterproof wallet in a jersey pocket or in a fanny pack under a jersey. In those modes I have never had an issue with the Florida heat.
I did have a phone that got hot and kicked off, but that was due to a failing lithium battery. It was actually swelled up. It apparently had nothing to do with ambient temperature. I have seen the same happen with other devices like chrome books and eBook readers. The fix was a new battery for devices that had a replaceable battery.
