No.
Covering the quilt will affect the heat dissipation of the battery, causing the battery to overheat, which will negatively impact the performance and battery life even if the quilt is covered, it cannot solve the problem; the problem of lithium iron phosphate batteries being afraid of cold. Because the battery's temperature is determined by the heat generated by its internal chemical reaction, the external ambient temperature can only indirectly affect the battery's temperature by affecting the battery's heat dissipation. battery.
Why do cell phones lose power quickly in cold weather?
Because the lithium batteries in Apple devices will increase the resistance of the electrolyte to the inside the battery in cold environments. the speed of the chemical reaction decreases and the current generated is also relatively reduced,so the power consumption of Apple devices is very fast and it is very cold in winter.

Chargers are divided into direct chargers and seat chargers. Direct charging converts mains powerur 220 AC into 5 V DC, which is input into the mobile phone and is lowered by the charging circuit of the mobile phone to be used by the battery. Generally, it will be delivered when purchasing a mobile phone. The charger is directly connected to the battery and converts the mains power into the required voltage for the battery to use.
Newly purchased batteries do not need to be charged for 12 hours for the first time, but it is better to complete a full charge and discharge process for 3-5 hours. Fully charged means 100% charged. normally, and full discharge means when the phone receives a low battery reminder. Because the battery needs to go through processes such as electrolyte filling, forming, charging and discharging, and capacity division before leaving the factory.
Detailed information:
The reason why cell phones quickly lose power in cold weather is because at low temperatures, the resistance of the electrolyte solution in the lithium battery of the cell phone changes significantly, causing damage to the battery.
In many people's minds, when the weather turns cold, cell phones also become sensitive to cold. But in fact, it is not cell phones that are afraid of the cold, but the lithium batteries contained in them. mobile phones.
At present, most mobile phone batteries on the market use lithium-ion batteries. Its working principle is based on the chemical reaction of the material of the positive electrode, the material of thenegative electrode and electrolyte inside the battery. There is electrolyte between the positive and negative electrodes of lithium batteries. When using a cell phone, the battery should be discharged. Lithium ions are precipitated from the negative electrode through a chemical reaction and move toward the positive electrode through the dielectric.Producing electron movement, thereby producing electric current.
In low temperature environments, because the chemical reaction speed in the battery slows down and the electrolyte resistance increases, the lithium ion crossover performance deteriorates, the activity decreases and the discharge current becomes smaller, making the available capacity of the battery is reduced. This creates the illusion that lithium batteries consume power quickly at low temperatures. The real reason is that the capacity of the lithium batterym itself is reduced due to the low ambient temperature.

In order to prevent the mobile phone from automatically turning off , in a low temperature environment, it is best not to use your mobile phone for a long time. When you go out, you should place your cell phone in a warm place such as a pocket or bag. You can also purchase a thicker cell phone case. for your cell phone to keep it warm.
It should be noted that mobile phones are more afraid of condensation caused by indoor and outdoor temperature differences than of low temperatures. When people bring their cell phones from a cold exterior to a warm interior, water droplets condense on the cell phones due to the temperature difference. If droplets of eaIf they penetrate the internal motherboard along the gaps in the phone case, the phone will become wet, causing it to freeze or even fail to boot.
Therefore, when the temperature difference is large, it is best to avoid direct exposure of the mobile phone outdoors. If you need to use the call function, you can plug in headphones to work.
