Why does the mobile phone lose power fast at low temperatures? Realme officially explains it this way

Zhongguancun online news: In the winter due to the low temperature, many consumers found that the mobile phone power down very quickly, charging is also difficult to fill, about these phenomena, realme official in the community to explain, let's take a look.

1. Why does your mobile phone appear to be charged or not enough?

Today's mobile phones on the market, whether it is Android or iOS, mostly use lithium batteries, and the ideal working environment temperature of the battery is between 15 ° C and 40 ° C. Under the low temperature conditions in winter, the internal chemical reactivity of lithium-ion batteries is reduced, resulting in slow charging and reduced usable capacity. In order to protect the mobile phone battery, the system sets up low temperature protection - in the case of low temperature conditions, the charging speed and charging limit will be automatically reduced; in the case of lower temperatures, stop charging and have a corresponding prompt message.

2. Why does the low-temperature mobile phone power down quickly?

Lithium batteries will reduce their capacity to protect themselves at low temperatures, so the battery life of mobile phones in cold environments may be shortened, such as electric vehicles in winter riding time will be shorter.

But this situation is only temporary, when the battery temperature returns to normal, the battery life will return to normal.

3. Why can't I flash charge at low temperatures?

In the winter low temperature conditions, in order to protect the battery, the intelligent VOOC flash charge will automatically reduce the charging current to prevent the battery from having safety accidents, so the mobile phone will be charged slowly, so consumers do not have to worry.

>> mobile phone charging reference temperature:

Normal: 0 °C-45 °C

Flash charge: 15 °C-35 °C

The iOS device that also uses lithium batteries (taking the iPad as an example) cannot be charged directly under low temperature conditions, and needs to be in a relatively warm environment to charge.

If your mobile phone has a slow charging in winter, charging dissatisfaction, and fast power consumption, realme officials recommend that the back shell of the mobile phone be slightly covered and then charged, and try to use the mobile phone in a relatively warm environment.
