For those who aren't interested in (nearly) fake news
Given the absence of information here (what temperatures, 100% of phones or just some, &c.), I note that the one Reddit post that did include temperatures noted it was -4 F (-20 C), which was way outside of Apple’s tech specs:
• Operating ambient temperature: 32° to 95° F (0° to 35° C)
• Nonoperating temperature: −4° to 113° F (−20° to 45° C)
And hopefully, way outside of any temperatures most punters will be experiencing in the UK this winter.
FWIW, the temperature ranges above are identical to those for the iPhone 8/8+, so I suspect there’s less here than meets the eye. Unless, of course, you live on Svalbard or in Minnesota.
