Is the slow charging of mobile phones related to the cold weather?

Slow charging of mobile phones has nothing to do with cold weather (that is, low ambient temperature), which mainly affects the power consumption rate of mobile phones.

Because most of the batteries used in mobile phones are lithium batteries (including more mainstream lithium-ion batteries), the anode and cathode of lithium batteries are electrolyte. In the process of use, electrons are generated from the negative electrode and reach the positive electrode through the electrolyte to form current, so the generation of current is a chemical reaction process, and one of the factors affecting the chemical reaction rate is temperature.

When the ambient temperature is too low, the resistance of electrolyte increases, the chemical reaction rate decreases, and the generated current also decreases relatively. Therefore, the reason for the increase of battery power consumption in low temperature environment is actually that the current generated by the battery decreases, which leads to the decrease of available power, so it will feel more power consumption when used.

Extended data Precautions for using mobile phones in cold weather (i.e. low ambient temperature):

1. Try not to expose your phone to low temperature. When we go out, we can put our mobile phones in a close-fitting place or in a bag with insulation effect. When we need to answer the phone, we can use Bluetooth headset or wired headset. If there are no conditions, try to shorten the time of each use.

2. Configure a thicker and warmer mobile phone case for the mobile phone. Theoretically, the more things wrapped outside the mobile phone, the slower the temperature conduction and the longer it can last in low temperature weather.

3. If the mobile phone is automatically turned off at low temperature, don't turn it on immediately when you return indoors, which will damage the components of the mobile phone until the temperature of the mobile phone returns to normal.

4. For some bulky electronic devices, such as SLR cameras and video cameras, which are inconvenient to carry around to keep warm, the lithium battery can be taken out and placed in a heat preservation place to keep the temperature of the battery not too low, and then taken out for installation and use when necessary.
