Why is the mobile phone charging slower when it is cold?

In fact, the chemical reaction speed of our mobile phone battery will be affected by temperature, and the ideal working environment temperature of the battery is between 15℃ and 40℃.

"

In the low temperature environment, the chemical reaction of lithium battery will become slow, so the current will become smaller, which will lead to the slow charging of battery and the decrease of available capacity, which will make us feel that charging is slow and power consumption is faster.

As for the lack of charging, it is to protect the battery of the mobile phone. The system is equipped with low temperature protection, which will automatically reduce the charging speed and upper limit of charging power at low temperature. If the temperature drops to a lower level, it will even stop charging the battery.

"

So if the drop-down status bar displays the prompt "The ambient temperature is too low to fully charge the battery", it means that the ambient temperature of the mobile phone is too low at this time, so it is recommended to move the mobile phone to a warm place indoors and charge it normally ~

How to prevent slow charging at low temperature?

Facing the phenomenon of insufficient charging, slow charging and fast power consumption in winter, what good methods can be taken to prevent it?

① Put a protective cover suitable for mobile phone in winter. When people go out in a cold environment, everyone will wear warm clothes. Similarly, when going out in winter, we can put a warm mobile phone case on our mobile phone.

② When the external environment temperature is very low, the available capacity of the battery decreases. You can choose to take a charging treasure out to avoid the trouble caused by fast power consumption.

(3) when not in use, try to put your mobile phone in a close-fitting pocket or bag, and don't hold it in your hand.

When in a low temperature environment, we can try to choose the above operations to reduce our power consumption.

Method of prolonging standby time

Low temperature factors limit the battery capacity, so what can be done to make the phone stand by for longer?

(1) Avoid too many background programs. Many software still hangs in the background after we quit using it. At this time, the software is still running quietly in the background.

2 Close some power-consuming services such as WIFI, Bluetooth, data network and GPS in time. Remember to turn it off in time when not in use. These services will quietly consume our electricity;

③ Reducing the brightness of the screen, turning on the power saving mode and power consumption protection can save electricity.
