I purchased my iPhone on a warm, summer evening. Soon it will be exposed to a New England winter with sub-zero temperatures. How will it perform?
Apple lists an official "nonoperational temperature" of -4° to 113° F (-20° to 45° C). Minus 4°F is entirely possible in my neighborhood. Does this mean my iPhone won't work?
These guys found out by placing an iPhone in a freezer with an ambient temperature of -20°C (-4°F) for about 30 minutes. The good news is that the iPhone performed all functions perfectly with a surface temperature around -10°C (14°F). The bad news: It won't work with gloves. Prepare for cold hands this winter.
