Reason:
1. The standard battery of Millet mobile phone is lithium ion battery, the best working environment is 0℃~40℃, the best non-working temperature (namely storage temperature) is -20℃~45℃.
2. When used at normal temperature, its lithium ions will remain active. The electrolyte inside the lithium ion battery will generate current through the change of the anode and cathode potential difference through the chemical reaction.
3. And when the phone is below 0 ℃, lithium ion diffusivity, which affects the lithium ion between is negative transfer activity, resulting in a decline in the battery charge and discharge performance and phone system will be identified as no electricity or power is extremely low, triggering the protection mechanism of the battery cell phone automatically shut down, so the cell phone work in low temperature environment, there may appear automatically shutdown or not boot phenomenon.
4. When the battery temperature returns to the normal operating range, its performance will return to normal. Therefore, it is suggested to pay attention to the temperature of the mobile phone environment and try to use it in an environment higher than 0℃ as far as possible.
5. In order to ensure the battery life, the mobile phone will have a low-temperature protection mechanism. When the temperature is lower than 15℃, the battery will enter the protection mode and begin to limit the current and voltage; When the temperature is close to or reaches 0℃ for a long time, the mobile phone may shut down automatically and can not be started.This is a normal phenomenon. It is recommended to recharge the battery when the ambient temperature is comfortable.
6. When the indoor and outdoor temperature difference is bigger, a lot of phone call from outdoor to indoor, didn't notice the change of environmental temperature, the water vapor condensation in the mobile phone motherboard, when dewing phenomenon is relatively serious, it is likely to cause the battery shows no, short circuit, etc, leading to cell phone suddenly automatic shutdown or crash phenomenon.
7. If the mobile phone automatically shut down or unable to turned on due to this reason, it is advised to go to the after-sales center for inspection.
