In daily life, mobile phone CPU is one of the features that are easily ignored by consumers. In fact, the most important thing for a smart phone with excellent performance is its' core ', that is, CPU. Here is the content about why the CPU temperature of mobile phone is high brought by Xiaobian. Welcome to read!
≫ & gt; & gt; click next to see why the CPU temperature of the phone is high
Why the CPU temperature of mobile phone is high:
If the frequency of use is too high, reduce the heat and turn off the self starting software.
1. Press and hold the home key (also known as the main screen key) for about 2-3 seconds, put the current 'task manager' option, click to enter the task manager - at the top of the screen, and then click the 'active application' option - click the 'finish' option.
2. Clear memory (go to Task Manager - at the top of the screen, then click 'memory' option - click 'clear memory' option).
3. If the program, check whether it is because the mobile phone is installed third-party software (such as 360 mobile phone management software), which is set to always run automatically.
The CPU is generally stable in the temperature range of 20 to 30 degrees. That is to say, the tolerance temperature of the CPU is 60 degrees. According to the maximum temperature of 35 degrees in summer, the CPU temperature should be 55 degrees, not more than 65 degrees. Of course, by analogy, if your ambient temperature is 20 degrees now, the CPU should not exceed 50 degrees.
The temperature of the CPU is different from the temperature when it is used and the manufacturer of the motherboard. The reason why the temperature increases is that the heat output of the CPU is greater than that of the radiator. Once the heat output and heat dissipation tend to balance, the temperature will no longer increase. The calorific value is determined by the power of CPU, and the power is proportional to the voltage. Therefore, to control the temperature well, it is necessary to control the core voltage of CPU.
In daily life, mobile phone CPU is one of the mobile phone performances that are easily ignored by consumers. In fact, the most important thing for a smart phone with excellent performance is its' core ', that is, CPU.
Why is the CPU of mobile phone hot
Because when the mobile phone is running large-scale games or high processing operations, the CPU runs fast, and it will heat up.
Causes of mobile phone fever
In addition to the weather and environmental factors, there are six main reasons for the fever of mobile phones. Let's see if you have been shot in your use habits
1. Running high energy consuming apps
Such as playing 3D games, playing movies, and transmitting a large amount of data, the CPU continues to run with high load.
2. Play games or talk while charging
Cell phone battery input and output at the same time, which will not only double the power loss, but also may cause damage to the battery performance, it is best to avoid this behavior.
3. Poor use of lithium battery or poor quality of Shanzhai machine
For iPhone users, it's not a problem, as long as you don't buy an iPhone & hellip that can replace batteries and double cards;
4. Mobile app failure
Sometimes the abnormal operation of some apps will take up a lot of memory and make the CPU run with high load.
5. Protective shell and other coverings
Some protective cases may affect the heat dissipation of the mobile phone and cause the mobile phone to get hot.
6. Root installs incompatible plug-ins
After root, install some plug-ins that start randomly and stay in the background for a long time, or incompatible plug-ins, which may cause the phone to get hot and hot.
Harm of mobile phone fever
The fever of mobile phone may not only make you feel too hot to hold, but also cause scald on the left cheek of someone who is close to the mobile phone for half an hour. It will cause damage to the battery, induce other risk factors and cause additional harm.
According to the theory, when the temperature of lithium battery increases by 10 ℃, the chemical reaction speed will increase by two times, which will accelerate the battery power consumption. This is the possible reason why the battery power consumption is faster in summer.
If the temperature is too high, more than 45 ℃, it will destroy the chemical balance in the lithium battery, resulting in the adverse side reactions and products in the lithium battery being intensified to produce more thermal reactions, triggering more dangerous situations.
Although the current lithium polymer battery has elastic packaging to absorb the energy of thermal expansion, with the expansion of the polymer packaging, it may squeeze into the circuit board and other parts, which is easy to cause short circuit or arc in the internal circuit of the mobile phone. The electric arc can produce a high temperature of more than 20000 degrees Celsius, which may ignite other polymer materials and flexible packaging, causing the danger of mobile phone burning.
How to solve the problem of cell phone perm
1. Avoid playing games, watching movies or talking while charging;
2. Avoid talking for a long time, put the mobile phone close to the cheek, and try to use the earphone;
3. Close the unused background program;
4. Turn off the auto download and auto update function of APP in 'Settings' -'itunes store and app store';
5. Avoid using the protective shell with poor heat dissipation, or remove it when it is hot;
6. Avoid using high energy consuming app programs for a long time;
7. If the mobile phone is hot, use the mobile phone cleaning software to clean up the memory will effectively cool down;
8. Stop using when charging to prevent danger.
9. If you hold it in your hand or put it in your pocket, it will transfer heat to each other. Try to put it on the other side with ventilation and heat dissipation. If you have air conditioning, let your mobile phone blow air conditioning together.
10. If it doesn't work, turn off the phone temporarily and let the temperature of the phone return to normal before continuing to use it.
