What to do if your ipad is too cold to charge all afternoon
The iPad can not be charged in winter, because in a low temperature environment, the low-temperature protection mechanism of the lithium battery will cause no chemical reaction of substances in the battery, so it can not be charged or the charging speed is slowed down.

It is understood that the working principle of lithium-ion batteries is that the internal electrolyte changes through a chemical reaction, resulting in a potential difference in the positive and negative electrodes to generate current. At low temperature, the electrolyte moves very slowly, which affects the transfer activity of lithium ions between the positive and negative electrodes, resulting in the deterioration of battery charging and discharging performance.

Simply put, in a low temperature environment, it is not that the lithium battery is really out of power, but that there is electricity but it cannot be released normally. Some analysis data said that ordinary lithium batteries at zero degrees Celsius, its capacity will be reduced by 20%, when it reaches minus 10 degrees Celsius, the capacity may only be about half.
The solution is as follows:
1, when the temperature is low, the ipad can not be charged, it is best to choose to cover the IPAD with a quilt, so that the temperature will naturally rise, and so on to a certain temperature, you can automatically charge.

2, when there is still weak electricity, while playing ipad, while charging, because in the process of playing, the phone will automatically dissipate heat, which helps to charge oh.
2, you can also put the iPad on the hand warmer treasure for one to two minutes, so that the iPad can be charged normally, remember that the hand warmer treasure should not be too high temperature, nor can it be placed for too long, one or two minutes can be.
3, we can also use a hair dryer, open the warm air mode, blow on the back of the iPad for about one or two minutes, the distance is controlled at about 30 cm, should not be too close. Then connect the charger to charge normally.
4, if there is air conditioning or floor heating at home, we turn on the heating function, and the iPhone can be charged normally after the indoor temperature rises
