Why does the iPad automatically disconnect when the battery is less than 20%?

The cold weather affected the battery. What's the temperature in your home? If the temperature of ipad is low, it can't be charged. The charging temperature should be higher than 10 degrees. It's okay to have heating in the north. There is no heating facility in winter in the south. If the indoor temperature is below 7 degrees, the ipad can't be charged, and the power is severely cut off. The reason is that lithium-ion batteries are equipped with low-temperature protection. You can use electric blankets, air conditioners or hair dryers, hot water bottles, etc. To heat the ipad.
