Who is the most delicate cell phone? The winter strikes.

Editor's note: For a person growing up in the south, it is difficult to understand the feeling of water pouring into ice. Because of the cold weather, the students in the north should be early to pack their own dumplings, but you have not paid attention to the hands of the digital equipment? Will they strike because of the low temperature? NET friend Dream: Last week in the Songhua River play, when the temperature is about zero, along the way with mobile phone to take pictures, mobile phone home no sound, put on the heating, a night to return to normal, this situation is not too low temperature caused? According to the information provided by users inferred, it is likely because of the temperature is too low, so that some of the functions of the mobile phone has been abnormal work phenomenon. I believe many friends in the north have a similar experience of this netizen: every winter, battery power consumption speed, cell phone unresponsive, the screen appears ghosting ... So what is the normal operating temperature of smartphones? Let's take a look at the iphone. According to Apple's official website, the normal operating temperature of the iphone is 0~35摄氏度, the best temperature is 22 degrees Celsius, and the non working temperature is-20~45摄氏度. For this temperature range, Apple has a more specific explanation, as shown in the following figure: Apple says the ideal temperature zone is between 16°C and 22°C. The important thing is that you can permanently damage the battery capacity by keeping the device in a place that is too hot for 35°c. In this case, the iphone battery can not be recharged for long periods of time, while charging for the device at elevated temperatures can further damage the device, which can cause irreparable damage even in high temperature environments. When you use a device in a very cold environment, you may notice a decrease in battery use time, but this is only temporary. When the battery temperature returns to normal operating range, its performance will return to normal. And look at the Android phone, because of the number of Android handsets, for example, Huawei's mobile phone, the company has given such data: but it needs to be explained that Huawei's 40-70 degrees Celsius storage temperature is only theoretical value, after all, some mobile phone materials in the 70-degree environment, May face the danger of roasting. Return to the problem of low temperature, in addition to the temperature too low will let the cell phone battery temporarily out of the question, if from the low temperature into the room outside, will make the water vapor condensation to the phone, into the motherboard to make the phone damp, so there will be a sudden crash or even can not boot. Therefore, in the case of sudden temperature change, try not to use mobile phone calls, or switch to headphones, to avoid direct exposure to the phone, or to the mobile phone to buy a thicker set of children, can play a certain protective role.
