Why do mobile phones use electricity so quickly in winter?

Not to mention the recent ice and snow weather, many friends have found that their mobile phones seem to be frozen as if they are also frozen, and the battery will automatically shut down when it is not used, what is going on? <>

The battery doesn't work very smoothly when it's cold, and if you live in a colder climate, you may notice this, for example, when the car has a hard time starting on a cold morning, or when waiting for a train in the cold wind on the train platform, the phone's battery level drops dramatically, but it's not all the battery's fault, it's not because technology is harder to work in the cold, it's the action of chemistry, and this problem is difficult to solve. It turns out that the batteries of mobile phones are lithium batteries, and under low temperature conditions, the lithium battery activity and the lithium intercalation activity of the anode active material will be affected. The capacity of the battery decreases and the rate performance decreases, so at low temperatures, the molecular activity of the electrolyte in the battery will deteriorate, and the discharge efficiency will be greatly reduced.

At the same time, the output voltage also decreases, and the problem of the battery is reflected on the mobile phone, that is, the chemical reaction speed slows down, the discharge current becomes smaller, and the mobile phone will automatically shut down. It's true that when you plug a battery into some device, the negatively charged electrons in the battery flow through the wires, but the battery is not simply a bucket with those electrons. Electrons are part of the initial neutral atom or molecule and are then released through a chemical reaction inside the battery, the result of the reaction is that the electrons move through the wire and meet the punctuated molecule on the other side of the battery, this movement creates an electric current that drives your device, the specific chemical reaction varies depending on the type of battery, but that's the basic principle of all batteries and that's where temperature gets involved.

Temperature is a measure of heat, for a molecule, heat is motion, its particles will shake around, higher temperature means more molecular movement, more molecules collide with each other, which makes chemical reactions more likely to occur. <>

Because mobile phones also heat up in winter, and the temperature is relatively low in winter, mobile phones dissipate more heat when they are hot, so they use more electricity.

Because today's mobile phones are lithium batteries, the chemical characteristics of lithium batteries themselves are not durable in a low temperature environment, so the standby time becomes shorter in winter.

The normal use environment of the mobile phone can not be below zero, and the temperature is too low to increase the power consumption of the internal parts of the mobile phone, which greatly affects the service life of the mobile phone.

There are many reasons for mobile phone battery consumption, and the common ones are as follows.

1. Do not turn off the mobile network or do not turn off the wifi search: With the abundance of mobile phone applications, the mobile phone function is becoming more and more powerful, and the use of mobile phone networking is becoming more and more common, if the user does not turn off the "mobile network" function or LAN wifi search function in time after the end of the mobile phone use, then the mobile phone is on standby in time, and has been searching and trying to connect to the Internet, resulting in unwanted power consumption, and the battery power consumption is very fast, and turning off the mobile network and Internet connection in time is also a good way to save power.

1. GPS power consumption: more and more users use WeChat, Momo and other social software for a long time, these software often need to turn on the GPS function to cooperate, for the GPS positioning function, you can locate by searching for satellites or using the Internet network, as long as GPS is turned on, it will also actively search for satellites, in indoor or some places with thick clouds, the satellite signal is very weak, GPS will increase the power search, resulting in fast power consumption, so if you decide to use the mobile phone standby, it is better to turn off the GPS function.

3. Too many background applications: Many users have installed a lot of applications on their mobile phones, although they bring convenience to life, but in actual use, many apps have been opened in the background regardless of whether the user has taken the initiative to open them, these processes continue to scan the network, constantly search for and update software, and the background program shows that it is intelligent to a certain extent, but the direct consequence is to cause the mobile phone CPU to run under high load, which is particularly power-consuming, so if the mobile phone is not necessary, do not install too much useless software.

4. Power consumption due to poor telecom network signal: When the telecom signal is weak, the mobile phone will automatically increase the power to search the network in order to maintain a stable connection with the main network, which is also very power-consuming.

5. The battery itself is worn out and the capacity is reduced: Some mobile phone batteries have been used for a long time, or the number of charging times has approached their limits, or the battery quality is unqualified and damaged, and its internal electric capacity is reduced, and it will also consume power quickly.

I believe that many friends will find such a strange principle about mobile phones, that is, in winter, especially in sub-zero temperatures, it feels like the mobile phone consumes power very fast, not only that, but the screen will become relatively slow to respond! Many people wonder, is it true that people are afraid of the cold in winter, and the mobile phone as a machine is also afraid of the cold? What the hell is going on?

In fact, the principle is very simple, at present, on the market, the main power supply battery in the mobile phone we use is the lithium-ion battery used, and the reason why the battery can work is mainly dependent on the positive electrode material in the battery, and the negative electrode material generates electricity through chemical reactions. In a low-temperature environment, the electrolyte will become more solidified, and the activity of the lithium battery will slowly decline, resulting in a gradual decrease in the power of the mobile phone, which is why the power consumption of the mobile phone in winter is faster. <>

Especially below 0 degrees, most of the mobile phone power consumption will be relatively fast, there are many friends like to use the Apple mobile phone, in the winter will always shut down, because Apple has set up a low temperature protection function, in the lower temperature will automatically shut down to protect the battery, once it returns to normal temperature, it will be automatically lifted, and why does this not happen to the Android machine? It is because the manufacturer has a wide range of critical points for this protection. <>

Especially in winter, when dialing **, the situation of power loss is more obvious, and basically a call will find that the electricity has dropped by about 20%. In addition, if the temperature of the phone is too low, the brightness of the screen will also decrease, and the response speed will be correspondingly slower. The most intuitive thing is that you can see the drag phenomenon on the mobile phone screen, so it is recommended that if you want to play with your mobile phone in winter, it is best to bring a thick silicone case to your mobile phone.

Not only can it effectively block the low temperature from the outside world, but it can also make the heat emitted by the mobile phone itself not lose too quickly, just like putting on a thick cotton jacket for the mobile phone!

The reason why the phone consumes power quickly in winter is because the temperature in winter is very low, and the phone will get hot in order to maintain performance, and hot means power consumption.

In a low-temperature environment, the electrolyte will become more solidified, and the activity of the lithium battery will slowly decline, resulting in a gradual decrease in the power of the mobile phone. It will automatically shut down to protect the battery when it is at a low temperature, and will automatically release it once it returns to normal temperature.

In winter, the temperature is low and the weather is relatively cold, and the battery of the mobile phone, under the condition of long-term cold, will accelerate the loss of the mobile phone battery and the loss of power.

Life tips: Don't worry about the fast power consumption of your mobile phone in winter, learn these tricks to extend the battery use time, let's take a look.

I think it's mainly because the weather is too cold, so the phone needs to consume a lot of power to maintain when it is running.

The reasons that affect power consumption generally include battery capacity, screen display, application operation, communication connection, etc., and the power consumption is different in different usage states.

If you're using a Huawei phone, here's how you can optimize your battery life

1.Use one-click power saving or one-click optimization to automatically diagnose optimization.

3.Turn on Smart Resolution to help save power.

4.Turn on the power saving mode.

Go to Settings > Battery and turn on Power Saver Mode or Super Power Saver.

Most of the batteries used in mobile phones are lithium batteries, and the positive and negative electrodes of lithium batteries are electrolytes, and in the process of use, the negative electrodes produce electrons, which reach the positive electrodes through the electrolyte and form an electric current, so the generation of electric current is a chemical reaction process. And one of the factors that affect the rate of chemical reactions is temperature.

When the ambient temperature is too low, the resistance of the electrolyte becomes larger, the chemical reaction rate decreases, and the current generated is relatively reduced. Therefore, the reason for the increase in battery power consumption in low temperature environment is actually the decrease in the current generated by the battery, resulting in a decrease in the available power, so it will feel that the power consumption is greater when used.

The reason is this: mobile phone batteries are mostly lithium-ion batteries, which usually consume more power in a low-temperature environment, and the lithium-ion battery itself will stop working when the temperature is lower than 10 degrees Celsius.

The acceleration of battery power consumption in low temperature environment is related to the chemical properties of lithium batteries themselves. Generally speaking, when the mobile phone detects that the battery capacity is low and the ambient temperature is low and the current is low, the temperature protection circuit in the battery's built-in protection board will automatically start, and the mobile phone will automatically shut down.

If you use a vivo mobile phone, there are more and more scenarios that need to use a mobile phone in daily life, and the power consumption is mainly related to the running status of the mobile phone, such as playing games, watching ** and live broadcasts, ** call and chat, running a large number of programs in the background and other scenarios will consume more power with ants; The brighter the screen of your phone, the louder the volume, or the more power you use over time, the more power you consume.

To reduce power consumption, it is recommended to operate the following methods:

1. For common use scenarios, such as using social software, listening to songs, watching ** and other scenarios with low demand for network speed, it is recommended to use 4G data network, and when you need to play games on a faster 5G network or load files at high speed, you can enable 5G data network again, which can effectively extend the battery life;

3. Adjust the software settings to appropriately reduce the image quality and frame rate, and the screen refresh rate model can be set to the normal refresh rate to reduce power consumption;

4. Clean up unnecessary programs in the background, and you can usually use the "one-click acceleration" function;

5. When GPS positioning, Bluetooth and other functions are not used, the function can be turned off to reduce the power consumption of the burial;

6. Go to Settings - Battery, and choose to turn on power saving mode, super power saving mode or sleep mode according to your needs.

01 The battery has low working efficiency in low temperature environment.

Mobile phone batteries generally use lithium batteries and nickel-metal hydride batteries.

And mobile phones consume power quickly in winter.

As far as lithium batteries are concerned, they can't withstand low temperatures.

The normal working temperature of the mobile phone is 0 35 years old, the best use temperature is 22, and the limit temperature is -20 45 Therefore, when the ambient temperature of the mobile phone is close to about 0, it will affect its work efficiency.

02What is the normal use temperature of the phone?

Optimal operating temperature: 16 —22

Normal operating temperature: 0 —35

Storage temperature range: -20 -45

The temperature is below 0

The phone will go into an automatic freeze state.

The temperature is over 35

The phone will alarm because the battery is overheating.

At the same time, it will automatically shut down.

Use the ambient temperature is too high or too low or lifted.

will affect the speed of the phone.

It may even lead to an automatic shutdown.

In addition, in a low-temperature environment.

Mobile phones will also be difficult to charge.

03Why does the mobile phone lose power in cold weather?

Most mobile phones use lithium-ion batteries.

This is what we usually call lithium batteries).

The interior consists of a positive electrode and a negative electrode.

and the composition of the electrolyte between the positive and negative electrodes.

The negative electrode precipitates lithium ions through a chemical reaction.

An electric current is generated during the movement of lithium ions to the positive electrode.

In a low temperature environment.

The chemical reaction of lithium batteries slows down.

As a result, the discharge current becomes smaller and the charge decreases.

04What are the power-saving tips for mobile phones in low temperature weather?

1. Reduce the brightness of the screen.

The biggest killer of your phone's battery.

It's not a CPU, it's not a hit.

It's getting bigger and bigger phone screens.

The default settings for a lot of phones are:

Automatically adjusts the brightness of the screen.

In this way, when the light is stronger.

Mobile phones generally work at maximum brightness.

And the power consumption at this time is almost.

It can be measured by the rate of 1% drop in two minutes.

So want to save electricity.

The first thing to remember is to reduce the brightness of your screen.

This will save a lot of power.

Especially for large-screen phones over 4 inches.

There are several reasons why mobile phones drain battery quickly in winter:

1.Decreased battery cleaning capacity: In winter, when the temperature is low, the battery capacity will decrease, making the phone drain faster.

2.Battery aging: Battery aging will cause the battery to decrease its capacity, which will make the phone consume more power.

3.Battery temperature: When the temperature is low in winter, the battery temperature will also drop, making the phone drain faster.
