Does temperature affect the battery life of a phone?

Temperature does affect the battery life, whether it's too cold or too hot, it will reduce battery life. SupercoolingWe know that lithium batteries work through the electrolyte inside the battery.

After the positive and negative electrodes are turned on, the negative electrodes pass through a chemical reaction.

Lithium ions are produced, which pass through the dielectric.

Swim to the positive electrode, and in the process of this movement, an electric current is generated.

When the temperature drops, the lithium-ion activity in the electrolyte becomes poor, resulting in a decrease in the current released by the battery. The actual experience for the user is that the battery is not used. When the temperature rises, the lithium-ion activity in the electrolyte returns to normal and the battery life is restored.

So in winter, some mobile phones can't be used normally when they are outdoors, but they will return to normal indoors when they are heated.

In addition, most mobile phones now use metal shells, and metal has strong heat dissipation and is not easy to gather temperature. In winter, when the temperature is low, the heat on the surface of the battery is quickly dissipated, and the discharge power of the battery decreases rapidly. Some of Apple's mobile phones have strict requirements for the voltage and current of the battery, and once the discharge power of the lithium battery is reduced, it may cause the Apple phone to restart unexpectedly.

So Apple has added a protection mechanism inside the system: when the ambient temperature of the fuselage reaches 0 degrees Celsius.

, the phone will be forced to shut down.

Android phones. Due to battery capacity.

Larger, usually above 3000mAh, some even reach 5000mAh. Therefore, even if the battery temperature is reduced, the activity of the lithium ions inside can still generate enough power to keep the phone running. Therefore, in the outdoors in winter, Android phones rarely have the phenomenon of forced shutdown, but the battery life is greatly shortened.

OverheatingWhen the temperature of the battery is higher, the faster the internal lithium-ion movement.

Every time the temperature of the battery rises by 10 degrees Celsius, the rate of chemical reaction of the battery is tripled. So when the battery temperature is too high, it will also lead to a shorter battery life. Under normal circumstances, when the battery temperature rises above 40 degrees Celsius, the power will be released quickly.

The second is also due to the increase in the temperature of the processor, memory, screen, and battery, which leads to an increase in the discharge rate. When the temperature of the battery exceeds 45 degrees Celsius, the chemical balance inside the battery is disrupted.

Happen. Therefore, the general mobile phone will have an overheating protection mechanism, such as prohibiting taking photos when the temperature is too high, turning on the flash, etc., reducing the frequency of the processor, or simply forcing the shutdown directly.

However, because the summer temperature in most parts of my country will not exceed 35 degrees Celsius, and the heat dissipation of mobile phones is generally better, the battery life shrinks due to battery overheating is not as frequent as in winter because of overcooling. Therefore, the overheating or overheating of the battery will affect the battery life of the mobile phone, and the serious situation will also lead to the shortening of the battery life. Therefore, it is best not to use your mobile phone for a long time in an excessively cold or overheated environment.

The temperature will affect the battery life of the phone, because the higher the temperature, the more power the phone consumes, and the shorter the time the phone will be used.

For electronic products, the temperature will affect the battery life, if the temperature and cold areas, the battery life of the mobile phone will be reduced, because the electrolyte resistance inside the battery becomes larger.

The temperature will affect the battery life of the mobile phone, if the temperature is too high, the battery of the mobile phone will be consumed quickly, and if the temperature is too low, the battery life of the mobile phone will be slower.

If the temperature is too low to enter the room, it will cause water vapor to condense on the mobile phone, enter the motherboard and make the mobile phone damp, so it will suddenly crash or even fail to turn on.

Therefore, in the case of sudden changes in temperature, try not to use mobile phones to talk, or use headphones to talk instead to avoid direct exposure of mobile phones, or buy a thicker sleeve for mobile phones, which can play a certain protective role.

For lithium-ion batteries, whether it is a national standard or an enterprise standard, there is a strict limit on the lower limit temperature of discharge: not less than -20. As for the charging temperature, it will not only specify the minimum temperature like discharge, but even clearly stipulate that it can only be charged at a small rate at low temperature, and cannot be fully charged (for example, it can only be charged at 0 15 degrees, and the upper limit voltage is.

The low-temperature discharge capacity of lithium-ion batteries will be reduced, but they can be recovered after charging and discharging at room temperature, which is a reversible capacity loss; However, low-temperature charging will cause lithium precipitation, which is a permanent loss of capacity.

Due to the greater harm of low-temperature charging and lithium precipitation, the low-temperature charging of lithium-ion batteries is more strictly controlled than that of low-temperature discharge. At present, many battery factories will use the method of "ladder charging" to describe the charging conditions of lithium-ion batteries.

If you are using a vivo mobile phone, the temperature is too low, and the charging time becomes longer: because of the low temperature characteristics of the battery, our charging current is currently controlled by the temperature zone, that is, the lower the temperature, the smaller the charging current will be, and the charging time will be correspondingly longer.

1. Don't wait for the battery to run out before charging; Over-discharge will have a certain impact on the battery, and in severe cases, it may cause the device to fail to turn on normally, try to charge it in time when the power is too low;

2. It is recommended to use the original charger and data cable for charging; Non-original chargers may have various problems that may damage the battery and reduce the life of the battery;

3. When charging, try not to play while charging, at this time, it is easy to increase heating, easy to lose the battery, and shorten the service life of the battery;

4. After the charging is completed, please disconnect the power supply in time to avoid charging for a long time;

5. Avoid using the equipment in a high-temperature environment.

Most of the heat generated by the mobile phone during use is generated by the work of the CPU, and the CPU should not exceed 30 degrees Celsius at room temperature (30 degrees Celsius at room temperature of 10 degrees). The main hazards of the mobile phone temperature above 40 degrees are as follows: 1:

The phone will feel hot at around 40 degrees Celsius2: Some phones will automatically activate the temperature control at 40 degrees Celsius, thereby reducing the CPU temperature to achieve the purpose of cooling down, but doing so will cause the phone to freeze. 3：

The high temperature of the mobile phone has a direct impact on the battery, and most of the current mobile phones use polymer lithium-ion batteries. The chemical properties of lithium are very reactive and easy to burn, when the inside of the battery continues to heat up, the gas expansion produced during the activation process will become dangerous, and the higher the temperature, the faster the capacity loss of the lithium-ion battery, and this loss is irreversible, that is, the capacity of the battery will be permanently reduced. In a 0°C environment, a lithium-ion battery with 40% of the remaining power will lose 2% of its capacity after one year of storage; At 40 degrees, a fully charged lithium-ion battery loses up to 35% of its capacity after one year of storage.

The solutions to the phone temperature is too high as follows:1:Clean up the phone memory and close some programs2:

Turn off the phone screen and leave it for a period of time 3: Turn off the phone and leave it for a period of time to maintain a good habit of using the hand luck Chang jujube machine: 1:

Don't disassemble and play with the phone during the charging process2: Don't overcharge or overdischarge the battery3: Regularly clean up the garbage and memory of the phoneGood usage habits have laid the service life of the phone, including the temperature, the temperature of the mobile phone will generally rise when playing games, which is inevitable, so don't play mobile games for a long time.

The temperature of the mobile phone is too high for a long time, and you can quickly cool down the mobile phone with it, and it will not damage the mobile phone.

The influence of temperature on the performance of mobile phone batteries is manifested in several aspects:

1.Battery capacity decreases: At different temperatures, the resistance of the mobile phone battery will continue to increase, and the battery capacity will be significantly reduced due to the increased polarization of the electrodes;

2.Reduced charging efficiency: At different temperatures, the battery electrolyte temperature will be very high if the mobile phone battery is repeatedly charged and discharged, and when charging at low temperatures, the diffusion current density of the mobile phone battery will decrease, which will reduce the charging efficiency;

3.Shortened battery life: When the temperature exceeds 45 degrees, the chemical balance in the mobile phone battery will be destroyed, resulting in side reactions in the battery, the performance of the battery material will be degraded at high temperatures, and the cycle life of the battery will be greatly shortened.

The high-current shrapnel microneedle module is selected for the mobile phone battery performance test, and the shrapnel microneedle module is used as the connection test module, which plays a good conduction role in the mobile phone battery test, and can transmit a large current of 50A, and there will be no current fading during the transmission process, and the test performance is stable and reliable!

1. Extreme temperature has the greatest impact on the battery, because the essence of battery charging and discharging is a chemical reaction.

The optimal temperature for a typical phone design is between 0°C and 35°C, too high a temperature (35°C) can permanently damage the battery capacity, and when the phone is used in a very cold environment (below 0°C), it will reduce the battery life and eventually cause the phone to turn off, but when the battery temperature returns to the normal range, its performance will return to normal.

2. Will the phone really be "frozen" and shut down? What damage does the cold do to a phone?

Yes, like my phone 5 will turn off.

If you are using a vivo mobile phone, the temperature is too low to reduce the activity of lithium electronics, which cannot make the battery perform at its best, which will affect the normal standby time of the mobile phone.
