Why does Apple's mobile phone consume so much power when it is cold?

Cold weather will affect the battery of iPhone.

The battery of iPhone uses lithium-ion battery, and its working principle depends on the positive electrode material, negative electrode material and electrolyte inside the battery to produce chemical reaction.

In the low temperature environment, due to the slow chemical reaction speed in the battery, the electrolyte will thicken, resulting in poor lithium ion permeability, reduced activity and smaller discharge current, thus reducing the available capacity of the battery and accelerating the power consumption of the mobile phone.

These working principles cause the illusion that lithium batteries consume electricity quickly at low temperature, and the real reason is that the capacity of lithium batteries is reduced due to the low ambient temperature.

Methods to reduce the power consumption of mobile phones;

1. To protect the battery of the iPhone, it is necessary to turn off the power consumption services of the mobile phone in time, such as mobile phone positioning, Bluetooth, hotspot WiFi and so on.

2. It can reduce the resolution and screen brightness of the iPhone.

3. Turn off the background running software of iPhone and clear the background applications on the mobile phone in time. In the iPhone battery management option, the background application of the iPhone is restricted, and the background application is automatically cleared after shutdown.
