My iPhone 6S Plus likes to shut off when it's really cold (Scandinavian winter). Is anything known if the 7/7+ behaves better in this regard? My thinking is that the battery gets cold from cold air entering the phone, and since the new phones are water tolerant there should be less air going into it. Maybe?
 
Both phone use the same battery chemistry and allow them to get cold soaked will shut either down. It is not cold air getting into the 6S.:rolleyes:

You need to keep you phone inside your clothing against your body to keep the temps within operating temperature. Take it out to use it but if really cold that will cause the battery to shut it down. Like Applejuiced suggested, check the manual for operating temps and you will see neither phone will operate if allowed to get cold. I am betting anything below freezing will shut the device down quickly if the phone is out in the open and allowed to get cold soaked.
 
Both have the same operating temperatures, so it's likely that the iPhone 7/7+ would shut down in a similar manner as your 6s+ does.

iPhone 7/7+
Operating ambient temperature: 32° to 95° F (0° to 35° C)
Nonoperating temperature: ‑4° to 113° F (‑20° to 45° C)
Relative humidity: 5% to 95% noncondensing
Operating altitude: tested up to 10,000 feet (3000 m)​

iPhone 6s/6s+
Operating ambient temperature: 32° to 95° F (0° to 35° C)
Nonoperating temperature: -4° to 113° F (-20° to 45° C)
Relative humidity: 5% to 95% noncondensing
Operating altitude: tested up to 10,000 feet (3000 m)​

If you’re wondering whether what you observe is normal or abnormal you should compare to how other phones behave in those temperatures. I’d suggest asking around.

There was another topic discussing it recently:
iPhone 6s switching off when cold
and the guy basically said that his phone kept shutting down while other people were using theirs just fine, so in that case it really looked like abnormality rather than the operating temperatures limitations.

Thanks for the reference on this. Learned something new today.
