Apple 6 mobile phone has been used for more than a year. Recently, the weather is cold. I found that the mobile phone always turns off automatically, which consumes a lot of power. What happened?

It is normal for mobile phones to use automatic shutdown in low temperature environment, because the lithium battery of mobile phones is affected by temperature changes.

The working principle of mobile phone lithium-ion battery is that the internal electrolyte changes through chemical reaction, and there is a potential difference between the positive and negative electrodes to generate current. In the low temperature environment, the movement of electrolyte is quite slow, which affects the transfer activity of lithium ions between the positive and negative electrodes, resulting in the decline of battery charge and discharge performance.

Therefore, in the low temperature environment, it is not that the lithium battery is really dead, but that there is electricity but it cannot be released normally. Some analysis data show that the capacity of an ordinary lithium battery will be reduced by 20% at zero degrees Celsius, and it may be only about half when it reaches MINUS 10 degrees Celsius.

Attention should be paid to the following items when using mobile phones in low temperature environment:

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 to the room, which will damage the components of the mobile phone until the temperature of the mobile phone returns to normal.

People's network-mobile phone freezes and shuts down automatically. Lithium battery products encounter extreme cold test.
