PSA: iPhone 6s,6s+ will power off in 25F or lower temperature (self.apple)

Was using my iPhone outside last night for directions and in about 5 mins it turned off and wouldn't come on. Friend had his 6s+ with around 50% battery, started to use that and it died too. Had to put it near his chest to warm it up, was able to get it back on and luckily get an uber home. The temperature was 23 degrees fahrenheit.
I never remember having this issue with my iPhone 4/5's and took them plenty very cold places (sub 20*f) and they never shut off.


I don't think anything changed via battery chemistry or the software for low temp shut down.
My theory is the larger 6 series iPhone act as larger heatsinks with their much larger surface areas. As a result, the 6 series iPhones will cool down a lot faster in the cold weather.
Also, when you're holding the iPhone, you can mostly cover the smaller 4, 4S, 5, and 5S iPhones with your hands (thus prevent a temperature drop even in really cold weather). With the 6 series iPhones, there is still probably large enough area of the iPhone exposed to rapidly cool down even while in your hands.
Basically 4, 4S, 5, 5S, 6, and 6S all shut down at the same temperature. It is just that the 6 and 6S cool down faster due to the larger surface area.

多少年的事情了，5时代就有这问题，零下5度到0度以上环境使用，苹果说明书上都有。以前这玩意普及率还不高，给下面员工培训时候都开玩笑说碰上自动关机的先问问是不是东北地区的，现在都记住成常识了

这次比以前严重，以前的说法是0～35度，现在十几度都能自动关机，几度关机的比比皆是，比以前严重多了
