My phone turned off by itself & couldn't turned it On while I was out for trekking & temperature was -40 oC. I use a leather casing for my iPhone. I was out of contact with my family during that time. Surprisingly when I turned it On upon reaching home it still showed 40% charged status. What's the lowest operating temperature for iPhone 4S?
iPhone 4S, iOS 7.0.4
