Will Apple's mobile phone be dead at low temperature?

Apple's mobile phone will be dead at low temperature.

The temperature is low, and it is normal for Apple's mobile phone to run out of power. The reason for this is that the ambient air temperature is too low, which will weaken the capacity of the battery. At this time, the battery of the mobile phone has been charged, but it cannot be released. Low temperature environment will also make the electrolyte of mobile phone battery inactive. All chemical reactions inside the battery will slow down.

Extended data:

Try to keep the room temperature when charging, and don't charge in a room that is too hot or too cold. We can remove the case when charging the mobile phone. It can ensure the low-temperature consumption of the mobile phone and naturally reduce the burden of charging. If you have a mobile phone case, you will find that the mobile phone is very hot. If you take off the case, you can charge the phone faster.

The electrolyte used in lithium batteries is an organic system. As an organic liquid, such as petroleum, it even becomes sticky and solidifies at low temperature. At this time, the activity of conductive lithium salt is greatly limited, so the charging efficiency is very low, resulting in slow charging and discharging and low temperature of lithium battery.

The charging requirements of lithium-ion batteries are very high. In order to ensure the accuracy of the termination voltage within 65438 0%, all major semiconductor device factories have developed various lithium-ion battery charging IC to ensure safe, reliable and fast charging.
