3c isn't very cold. it's an ambient temperature any phone would have to be able to withstand for an indefinite period to be marketable even in many US states.

It's the batteries more than anything else, most phones will loose their battery capacity in cold weather.

Wil lose. One O.

Losing capacity is one thing, shutting down and refusing to start after 10 min outside is another. What use is a phone if i can't call 112 because it's cold?

Edit: Also remember that I've had Apple laptops before, and only this newer model deems it necessary to shut down.

> What use is a phone if i can't call 112 because it's cold?

You're right, we should just ditch them. What use are they?

Yes, literally. If my phone would not work at 10C, I would replace it immediately, then burn it.

The point of a mobile phone is to be usefull outdoors, and sometimes your life depends on it. There are no two ways about it in my view.

yes, one O.

That's a battery technology limitation, you wanted a lightweight high capacity and low memory effect battery? the cost is bad temperature range. Otherwise pull out an old phone with NiMH batteries for your 911 calls

Try to use an eInk device in cold weather, its response time becomes terrible down to almost unresponsive. Again that's a technology limitation.
