General smartphones like apple what in winter, it's easy to shut down, mainly because of the climate temperature is too low. So what kind of mobile phone can be used normally in low temperature environment. Long-withering tongda Q10 series and Q8 series is three tablet after low temperature test, can be used normally in - 40 ° environment.

We all know that the operation of tablet and mobile phone from a battery powered support, the key lies in whether the battery can not influenced by temperature. We all know that the battery of the sort is more, have a lithium battery and carbon zinc batteries and alkaline batteries, etc., all of them at the time of the day is cold power loss particularly fast.

Commonly used in the mobile phone battery is lithium polymer, chemical reaction to produce electronic flow. But when the battery temperature is too low, lithium metal deposition phenomenon will occur in the battery becomes inactive, no longer produces the chemical effect, indirect reduce power. Actually lithium battery optimum operation temperature is 0-45 ℃, the temperature for the cell phone battery can be normal operation, but when the temperature is close to 0 ℃, and its efficiency is lower. When the temperature is low, the metal of the resistance is reduced, the power flow. At the same time for more than 45 ℃, overheating can make metal resistance will also increase, will also affect the electron flow (Q = I * t). Cold can make the metal fuselage of mobile phone more apparent in the above situation.

Is also influenced by the temperature in addition to the battery discharge, charging, principle and lithium metal deposition, and particularly in the high capacity battery. General lithium ion battery protection will set the temperature is too low, because of the low temperature charging, the battery can produce deposition of metallic lithium, affect the service life of the battery. In addition, the summer high temperature will also affect the use of lithium-ion batteries and on hot days, equipment a shorter charging time, but power consumption will be particularly fast, high temperature can also damage the battery charging.

Then the long-withering tongda tablet, mobile phone can be used under the environment of to 40 °, its battery and how to do? Learned long-withering tongda is three tablets, mobile phones all cryogenic battery material is the use of the "pure cobalt acid lithium", this kind of material of the battery is not only more resistant to low temperature, at the same time also can reduce the power consumption of the mobile phone, cell phone can be used normally in low temperature environment. The can do is three domestic mobile phone manufacturers almost none. Of course in addition to battery, mobile phone hardware itself allows various aspects also needs strength.
