Nowadays, smart phones have become more and more popular, and everyone is very concerned about the problem of mobile phone fever when using smart phones. As a kind of electronic products, it is obviously unrealistic to completely suppress the fever of smart phones, but we still have some tips to keep smart phones from overheating in daily use. Let’s take a look at the fever of the mobile phone. How to solve the problem of mobile phone heating and power consumption?
First, the cause of mobile phone fever
Battery reasons, running too many large programs, high CPU load, damage to internal components, etc.
1. When the cell phone number strength is -75dBm, the signal strength becomes very poor. In order to ensure normal cell phone communication, the cell phone will automatically increase the transmission power. The higher the cell phone power, the greater the cell phone fever.
2. Multiple background applications run together, which leads to CPU overload, and the thermal effect of the current generated by it can be imagined. Moreover, the theme, background and screensaver are all users of TV University, which leads to the fever of the mobile phone. Especially when navigation, games and videos are running, when these programs are running, gps navigation, Bluetooth, wifi or hotspots will be turned on, which is very easy to cause serious fever.
3. When users use mobile phones to surf the Internet and transmit more data, the greater the power consumption, the higher the CPU utilization rate and the higher the calorific value.
4. The power consumption of the mobile phone when talking for a long time or using audio and video is very large, that is to say, its battery has a small equivalent load resistance, and it is discharged with a large current when working. After discharging a part of electricity, the internal resistance of the battery increases, but the current required for the work of the mobile phone cannot be reduced, so a considerable part of energy is consumed on the internal resistance of the battery, which leads to the battery heating.
5. Because people are used to holding the mobile phone with their hands, the mobile phone cannot dissipate heat. If you use your mobile phone for a long time and the heat dissipation is not good, it will also cause your mobile phone to heat up.
6. Charging with a non-original charger leads to the fever of the mobile phone. Such a charger lacks a protection circuit, which cannot guarantee the stability of the current when charging, and it is easy to burn out the battery, shorten the service life of the battery, and even have the danger of explosion.
7. When you play with your mobile phone while charging, the battery will heat up when it is charging, such as making phone calls and playing games, which will aggravate the fever. If the weather is hot and the mobile phone is covered, the mobile phone is very easy to get hot, and it is also easy to get hot with a thick mobile phone cover.

8. Hardware or battery failure of the mobile phone itself can also cause burning, but generally this kind of situation is less.
Second, the consequences of abnormal fever in mobile phones
If the abnormal fever of the mobile phone is not handled in time, it is easy to cause the following problems:
1) The most direct thing is to damage the battery and reduce its service life.
2) Damage to other mobile phone hardware, and the most extreme case is that the mobile phone explodes and hurts people.
3) It may cause system disorder, and it is easy to dial the phone by mistake and open the application indiscriminately.
Third, the handling method of abnormal fever of mobile phone
After abnormal fever occurs, you can use the following methods depending on your environment and specific application:
1) Physical cooling if possible. Put it in the air outlet of the air conditioner, or throw it into the refrigerator to cool down urgently. After the temperature drops, it won’t hurt the phone itself, then check what power-consuming programs are opened and turn it off.
2) When it is already very hot, turn it off immediately. After shutting down, it is equivalent to killing all the programs, and then turning it on after the temperature drops.
3) When the fever trend is relatively large, you can turn off gps positioning, wifi, Bluetooth and even direct flight mode. Or play games for a long time, just have a rest.
4) Other conditions, such as unplugging the charging cable, removing the phone case, or getting hot, let the phone rest.
Fourth, the reasons for mobile phone batteries
The damage of mobile phone battery is an important cause of mobile phone fever. With the mass production of mobile phones, their quality is uneven. Especially the cell phone battery is a problem that puzzles people. If your mobile phone has two batteries, change the other battery to see if it is still hot. If it is no longer hot, it means it is a battery problem. If it is still hot, please see the second method.
Solution to fever caused by running programs: Today’s smart phones can run applications that can only be run on computers before, but some inherent defects of mobile phones will bring us trouble, that is, fever. If you open too many applications, the load on the CPU of the mobile phone will be high, and the heat will be great. The solution is to close some large-scale running programs, and other programs that are not used should also be closed. If the phone is still hot after taking this method, please see the third method.
Solution of internal component damage: If you use the above two methods, the phone is still very hot, then you should consider the problem of internal component damage. If your mobile phone is still in the warranty period, you can take your mobile phone to the merchant for warranty or replacement; If your mobile phone has passed the warranty period, you need to pay for it.
1. When the mobile phone is at normal room temperature, it is normal for it to heat less than 50℃. When the mobile phone is very hot, remove the back cover of the battery and force heat dissipation.
2. It is best to use the original charger, and it is best not to play with the mobile phone when charging.
3. Develop a good habit of locking the machine; Don’t press the home button when you exit the program. Press home to build the program, which is still running in the background. Develop unused applications and clear them with one click in program management.
4. Charging for too long will damage the battery and generate heat. The normal charging time of the mobile phone is 3-5 hours. How to charge the mobile phone > >
5. If the mobile phone battery feels a little hot when charging, if it exceeds 50℃, immediately return to the standby state or replace the battery. If charging, immediately unplug the charger. What should I do if my mobile phone battery is not fully charged? > >
6, often do the "one-click cleaning" background program for the mobile phone, and usually turn off some unused function switches, such as WIFI, GPS, automatic synchronization, etc., and appropriately reduce the screen brightness, which will greatly reduce the body heating phenomenon.
V. Precautions for preventing abnormal fever of mobile phones
Mobile phones are used for making phone calls, playing games, chatting, etc. It is impossible not to use them for fear of fever, but we can pay more attention to things at ordinary times, which can improve this situation. It can only be said that it is an improvement. If it is to be thorough, it can only rely on the improvement of the functional performance of mobile phone manufacturers.
1) You can prohibit the background automatic update program of the mobile phone or the background upload and download of icloud. Because these may cause unexplained fever.
2) Try not to play with your mobile phone while charging.
3) If you wear a cover for your mobile phone, choose a material with better heat dissipation. If possible, you don’t need a cover. When you use your mobile phone in daily life, as long as you develop good habits, be careful not to fall and bump.
4) If you are playing online games or navigating for a long time, control the time or take cooling measures.
Six, mobile phone power consumption situation and solutions.
Fast power consumption of mobile phones has always been a worry for mobile phone users. It’s a bolt from the blue when the mobile phone is playing without electricity. So is there any way to solve the problem of fast power consumption of mobile phones? The answer is yes! As long as you prescribe the right medicine for the following points.
Case 1: There is virtual power in the mobile phone.
There is virtual power in the mobile phone, which means that when you turn it on, it shows full power, but when you turn it off and then connect the charger, you find that the power display is actually only about 80%.
The Android system generally judges the battery charge according to the battery voltage, and there are two modes to recognize the voltage.
One is software identification, that is, the power displayed on the mobile phone after you boot into the system; The other is hardware identification, that is, when the charger is connected, the power displayed by the mobile phone is not turned on.
Usually, the voltage of software identification is higher than that of hardware identification. Therefore, it will appear that when we turn on the battery, it is full. After turning off the battery and connecting the charger, we find that there is actually only 80% or even lower power. Want to fill it up? It will continue to charge for a long time!
In fact, we often don’t fully charge our mobile phones, wasting part of the battery capacity, and naturally feel that the power is falling fast!
Solution:
Check whether there is virtual power in your mobile phone first: it is fully charged when it is turned on, and then turn it off and connect the charger to see if it is fully charged. If there is virtual electricity, then turn it off and fully use it, and see if it will be powered off again!
Case 2: Too many background programs increase CPU power consumption.
Don’t be careless about this old-fashioned question. What’s not so good about Android is that it will automatically run in the background after the program exits. Moreover, in the case that there is generally no problem with mobile phones, these background programs are often the biggest culprit in power consumption!
There are also the screen brightness of the mobile phone itself, the opening of wifi, Gps, Bluetooth, etc., and other settings, etc. These seemingly insignificant little things are actually big power consumers.
Solution:
1. Clean up the background operation of the mobile phone regularly to solve the problem that unnecessary programs occupy running memory and increase CPU power consumption.
2. Turn down the brightness of the mobile phone screen, turn off wifi, Bluetooth, etc. when not in use, and turn off power consumption settings such as button sound and button vibration.
3. Think about whether you have installed a program recently, uninstall it first, and see if the power consumption of the mobile phone is back to normal. Many small programs we ignored actually consume amazing power!
Situation 3: Battery aging
Nowadays, most smart phones use lithium batteries, and the average life of lithium batteries is 2-3 years. After 400-500 times of charging and discharging, it will accelerate the aging speed and become less and less durable.
If we use the mobile phone battery incorrectly every day, it will easily lead to battery aging and battery life decline.
Solution:
Proper use of mobile phone batteries is the best way to prolong battery life.
The problem to be solved now is, how do we judge whether the mobile phone battery is aging?
1. If the battery has been used for a year or so, according to your usual usage habits, the mobile phone will charge quickly and consume electricity quickly, which is likely to have begun to age.
2. Check to see if there is a bulge in the battery. If there is a bulge, it means that it is not just aging, but the battery is no longer usable. For safety reasons, it is better to change the battery as soon as possible.
3. After using the mobile phone for a period of time, the battery body has been burning, so you should change the battery as soon as possible.
Situation 4: Caused by improper brushing
In order to get ROOT privileges or other factors, many people quickly brush up when they get a new machine. But not long after, I found that mobile phones are prone to various problems, especially the power consumption will increase rapidly, which is really disturbing!
In this case, generally speaking, the brush is incomplete, resulting in program errors, and then the program will be run repeatedly, and the power consumption will naturally accelerate!
Solution:
The major brushing systems may have some defects more or less, and some programs on the mobile phone hardware can’t be called, and then these programs will be tried again and again, which is invisible to us. Only after brushing the machine and finding problems when using the mobile phone will we know!
At this time, it is best to find someone to help you refresh the machine, refresh the original system or the official ROM system, and then manage the system startup and self-startup software, which can be solved perfectly.
Case 5: Short circuit and leakage of the mobile phone motherboard.
For those who are familiar with mobile phone hardware, you can manually remove it, and check whether a patch capacitor on the main board of the mobile phone is in poor contact, which leads to a short circuit and causes the mobile phone to heat up, and then check to see if there is any leakage.
Of course, this must be tested by professionals, which is more difficult for ordinary people.
Solution:
Take it to a mobile phone after-sales service point for testing, or go to some regular mobile phone repair shops, and let professionals test it for you. After determining the problem, you can prescribe the right medicine!
Seven, mobile phone power consumption is fast, you can also try the following methods.
Don’t let the battery run out.
The mobile phone battery is fully charged and then consumed, and this cycle avoids the "memory effect". In fact, this practice is only applicable to Ni-Cd or Ni-MH batteries, not to lithium batteries. At present, most smart phones use lithium batteries. The author suggests that in order to prolong battery life and protect battery health, users should fully charge their mobile phones before running out of power.
Positioning setting
When users use mobile phones, some LBS-based applications often track users’ location, which will also increase power consumption. Although the power consumption increases, users of these applications often use them, and tracking the location can make the applications serve users better. At this time, users can find the corresponding application in Settings-> Privacy-> Location Services, and set the location information that they are allowed to access as "during the use of the application", which can save a lot of electricity when the application is not used. Of course, if you don’t need the location service of this app at all, you can set it to "never".
Better use of WiFi network
Under normal circumstances, users want to be online around the clock. Mobile phone network is undoubtedly a good choice, but at the same time it also means faster power consumption, especially when the mobile phone signal in the user’s area is not good, the mobile phone will frequently search for operator signals, which will increase power consumption. At this time, if the WiFi network can be used, the mobile phone does not need to search for signals frequently.
However, users need to remember that when leaving the WiFi hotspot, users can turn off the WiFi connection. Generally speaking, it is to let the mobile phone stay in a stable network, and it is not necessary to search for signals frequently, so that the mobile phone can save more electricity.
Appropriate use of flight mode
Similar to the situation mentioned above, there is no busy mobile phone or WiFi signal in the underground high-speed rail, because the mobile phone will keep searching for connections, which will lead to an increase in power consumption. The user can set the mobile phone to flight mode before returning to the place with signal. In addition, turning on flight mode before going to bed is also a good way to save electricity.
Low energy consumption mode
If you don’t have the rechargeable conditions at hand for the time being, and you want the mobile phone to save as much electricity as possible, users can consider turning on the low energy consumption mode of the mobile phone. Take the iPhone as an example. When the power is only 20% and 10%, the mobile phone will automatically remind the user to turn on the low-energy consumption mode.
Low-power mode will temporarily reduce power consumption until your mobile phone is fully charged. When this mode is turned on, you will stop viewing acquisition, background application refresh and automatic download, and weaken or turn off some visual effects. When the iPhone is charged to 80% capacity, the low-power mode will be automatically turned off.
Find a big power consumer
Now, no matter which mobile phone, you can count the major power consumers in the system for a period of time. As long as you know who consumes a lot of power, users can optimize their use. The mobile phone is running out of power, and you must have overdone one of your applications. IPhone users can get an overview of the most power-consuming applications in the past 24 hours and the past week in the "Battery" option.
Android users can also select the "battery" option, and the system will display a chart of power usage since the last charging and a list of applications that use the most power.
