What should I do if the iPhone shuts down automatically due to the cold weather?

Northerners rely on heating for winter, southerners rely on integrity for winter, but iPhone can only recognize. This cold current is too fierce. Recently, I saw many netizens say that their iPhones were inexplicably shut down automatically, and the iPad was out of charge. I couldn't find any fault at the local repair shop.

Actually It's too cold! Due to the recent nationwide low temperature, the requirements of Apple's official website for the operating environment of its electronic products show that the best operating environment for iPhone, iPad, iPod and Apple Watch is 0 ℃ - 35 ℃, while the best operating environment for MacBook is 10 ℃ - 35 ℃. At present, many areas in the north are below - 10 ℃, and the temperature is too much lower than the optimal operating temperature of the iPhone.

When the iPhone is below 0 ℃, the ion diffusion of the positive and negative electrodes becomes poor, and the discharge capacity becomes weak, the system will recognize that there is no power. At this time, the phone will have a large number of "power trips" in a short time, and even trigger the battery self-protection mechanism to automatically shut down the phone.

In addition to the iPhone, Android phones will also be affected by the automatic shutdown. To be precise, this is the case for phones that use lithium ion batteries.

The electrolyte inside the lithium-ion battery generates current by the potential difference between the positive and negative electrodes through the change of chemical reaction. At low temperature, the electrolyte will move very slowly, which will affect the transfer activity of lithium ions between the positive and negative poles. The battery charging and discharging performance is reduced.

However, there is no need to worry too much. If the phone is turned off due to cold weather, this situation is only temporary. When the battery temperature returns to the normal operating range, its performance will return to normal.

What should I do if I hurry to use my mobile phone?

Want to return to normal as soon as possible Use a hair dryer to blow the back cover of the iPhone or iPad until it is slightly hot, that is, about 40 to 50 degrees In fact, in addition to the discharge process, the charging process of the lithium-ion battery is also affected by the low temperature. For example, there are many cases where the iPad cannot be charged at low temperature. In addition to the hair dryer mentioned above, it can also be used use Put the hand warming treasure on the back cover The problems were basically solved.
