Recently, several users in northeastern China have complained on social media that their newly purchased foldable smartphones malfunctioned in extreme cold weather—issues included screens failing to unfold properly, unresponsive touch controls, and even complete blackouts. Some users reported that when temperatures dropped below -20°C, their phones stopped working within minutes of being taken outdoors from a warm indoor environment. Experts explain that foldable phones are particularly vulnerable to extreme temperatures due to their complex structures, flexible OLED displays, and precision hinges. Cold weather can drastically reduce battery performance, make screen materials brittle, and cause lubricants in the hinge mechanism to solidify, impairing both folding functionality and display quality. Most manufacturers recommend operating these devices within a temperature range of 0°C to 35°C—far above typical winter conditions in northeastern China. While some high-end models offer limited cold resistance, most foldables aren’t specifically optimized for such frigid environments. Industry insiders advise users in cold regions to minimize outdoor exposure or keep phones close to the body to retain warmth. This incident has sparked broader discussions about the geographic adaptability of consumer electronics, highlighting the need for enhanced hardware testing and design improvements tailored for extreme climates.
近日，多位东北网友在社交平台上吐槽，称自己新买的折叠屏手机在严寒天气下出现故障，如屏幕无法正常展开、触控失灵，甚至直接黑屏。有用户表示，当气温降至零下20℃以下时，手机刚从室内拿到室外不到几分钟就“罢工”了。专家指出，折叠屏手机因结构复杂、采用柔性OLED屏幕和精密铰链，对极端温度更为敏感。低温会导致电池性能骤降、屏幕材料变脆、润滑油脂凝固，从而影响开合顺畅度和显示效果。厂商通常建议的使用温度范围为0℃至35℃，而东北冬季远低于此标准。尽管部分高端机型具备一定耐寒能力，但多数折叠屏手机并未针对极寒环境做专门优化。业内人士建议，寒冷地区用户在户外使用时应尽量减少暴露时间，或将手机贴身存放以保持温度。此次事件也引发对电子产品地域适应性的讨论，未来或需加强针对高寒地区的硬件测试与设计改良。
