Isn't it too cold if Apple's mobile phone doesn't turn on?

Yes, because the cold weather will increase the resistance of the electrolyte inside the mobile phone battery, and also reduce the chemical reaction inside the battery, which will lead to the battery tripping. When charging, there is no way to release it, and then there will be the phenomenon of automatic shutdown. In a cold environment, if the battery activity cannot be restored, the mobile phone cannot be turned on.

Extended data:

Lithium batteries are divided into lithium batteries and lithium-ion batteries. Both mobile phones and laptops use lithium-ion batteries, also known as lithium batteries. Batteries generally use lithium-containing materials as electrodes, which is the representative of modern high-performance batteries. Real lithium batteries are rarely used in daily electronic products because of their great danger.

Lithium ion batteries have high energy density and high average output voltage. Small self-discharge, good battery, less than 2% per month (recoverable). No memory effect. The working temperature range is -20℃ ~ 60℃. Excellent cycle performance, fast charge and discharge, charging efficiency as high as 100%, high output power. Long service life. It does not contain toxic and harmful substances, so it is called green battery.

Avoid using the battery in harsh conditions, such as high temperature, high humidity, and long exposure to the summer sun. And avoid putting the battery into the fire. When removing the battery, ensure that the electrical appliance is in a power-off state; The service temperature should be kept between -20 ~ 50℃. Avoid "storing" batteries in electrical appliances that have been out of use for a long time.
