How to do if the phone is overheat

First, the cause of fever in mobile phones

The battery causes too many large programs to run, causing high CPU load and internal component damage.

When the mobile phone number strength is -75dBm, the signal strength becomes very poor. In order to ensure normal mobile phone communication, the mobile phone will automatically increase the transmission power. The mobile phone power is large, and the mobile phone heat is also greater.

Multiple background applications run together, causing the CPU to be overloaded. The current thermal effect generated by the CPU can be imagined, and the theme, background, and screen saver are all used by the electric users, causing the mobile phone to heat up. Especially in the case of navigation, games, and video running, these programs will start gps navigation, Bluetooth, wifi or hotspots when running, which is very likely to cause serious fever.

When the user uses the mobile phone to access the Internet and the data transmission is large, the power consumption is larger, the CPU usage rate is also increased, and the heat generation is large.

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 a large current discharge during operation. After the battery is discharged, the internal resistance increases. However, the current required for the operation of the mobile phone cannot be reduced. Then, a considerable part of the energy is consumed on the internal resistance of the battery, causing the battery to heat up.

Because people are used to holding the phone by hand, causing the phone to not dissipate heat. Using the phone for a long time and poor heat dissipation can cause the phone to heat up.

Using a non-original charger to charge, causing the phone to heat, such a charger lacks a protection circuit, can not guarantee the stability of the current when charging, and easy to burn the battery, shorten the battery life, and even the danger of explosion.

When you are charging, you can play with your mobile phone. When the battery is charged, the battery will have a fever. It will happen if you make a phone call or play a game. If the phone is hot and the phone is covered, the phone is very hot. With a thick mobile phone case is also prone to heat. Mobile phone case knowledge encyclopedia.

The phone’s own hardware or battery failure will also cause hot, but generally this type of situation is less.

How to do if the phone is overheat

Second, the consequences of abnormal fever

If the phone is abnormally hot, if it is not handled in time, it is easy to cause the following problems:

The most direct is to damage the battery and reduce the battery life.

Damage to other mobile phone hardware, the most extreme case of mobile phone explosion, injury to the person.

It may cause system disorder, easy to dial the phone, open the application, and so on.

Third, the mobile phone abnormal heat treatment method

After an abnormal fever occurs, depending on your environment and the specific application you are opening, you can use the following method:

If there are conditions, physical cooling. Put it in the air outlet of the air conditioner, or throw it into the refrigerator to cool down urgently. After the temperature is lowered, it will not harm the phone itself, then check the power-consuming program and turn it off.

When it is very hot, turn it off immediately. After shutting down, it is equivalent to killing all the programs, and then turning on the power after the temperature has dropped.

When the trend of fever is relatively large, you can turn off GPS positioning, wifi, Bluetooth, and even direct flight mode. Or take a break after playing the game for a long time.

If you have other conditions, or if you have unplugged the charging cable, removed the phone case, or are hot, let the phone rest.

Fourth, the reason for the mobile phone battery

Damage to the phone battery is an important cause of fever in the phone. With the mass production of mobile phones, the quality is also uneven. Especially the mobile phone battery is a problem that plagues people. If your mobile phone has two batteries, then look for another battery to see if it is still hot. If it is no longer hot, it means that the battery is a problem. If it is still hot, please see the second method.

Solution to heat caused by running the program: Today’s smartphones can run applications that were previously only available on the computer, but some of the inherent flaws in the phone can cause us annoyance, which is a fever problem. If you open too many applications, then the load on the mobile CPU will be high and the heat will be very large. The solution is to close some large programs that are running, and other programs that are not used should be closed. If the mobile phone is still hot in this way, please see the third method.

Solution for internal component damage: If you are using 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 under warranty, you can take your mobile phone to the merchant to request warranty or exchange; if your mobile phone has passed the warranty period, then you need to pay for repair.

When the mobile phone is at normal room temperature, the heat does not exceed 50 В°C. It is normal. When the phone is very hot, remove the battery back cover and force heat dissipation.

It is best to use the original charger, and it is best not to play the phone when charging.

Develop a good habit of lock machine; do not press the home button when exiting the program, according to the home build program is not turned off, still running in the background; develop unused applications in the program management one-key clear.

If the battery is charged for too long, the battery will be damaged and heat will be generated. The normal charging time of the mobile phone is 3-5 hours. How to charge the phone.

If the mobile phone battery is charging when it feels that the mobile phone is a little hot, if it exceeds 50 В°C, it will immediately return to the standby state or use the replacement battery. If it is charging, immediately unplug the charger. What if the mobile phone battery is not full?

Often do the “one button cleaning” background program on the mobile phone, usually also turn off some unused function switches, such as WIFI, GPS, automatic synchronization, etc., appropriate to reduce the screen brightness, which will greatly reduce the fuselage Fever phenomenon.

Five, to prevent the abnormal heat of the phone

Mobile phones are used for phone calls, games, chats, etc. It is impossible to use them because they are afraid of heat. It is only normal that we can pay more attention to matters that can improve this situation. It can only be said to be improvement. To be thorough, it can only rely on the improvement of the functional performance of mobile phone manufacturers.

You can disable the mobile background automatic update program, or icloud background upload and download. Because these may cause unclear fever.

Try not to play the phone while charging.

If you bring a set of mobile phones, the material selection is better. If you can, you don’t need a mobile phone case. When you use your mobile phone every day, you should develop good habits, and don’t fall and bump.

If it is a long time online game or navigation, control time or do cooling measures.

Sixth, mobile phone power consumption situation and solution

The power consumption of mobile phones has always been the heart disease of mobile phone users. It is simply a blue sky when the mobile phone is playing and playing. Then there is no way to solve the problem of mobile phone power consumption? The answer is yes! As long as you are correct for the following points.

Case 1: The mobile phone has virtual power

The meaning of virtual power in the mobile phone is that you display the full power state when you turn it on, but after you turn it off, you can connect to the charger and find that the power display is only about 80%.

The Android system generally determines the battery power based on the battery voltage. The voltage has two recognition modes.

One is software identification, that is, the amount of power displayed on the phone after you boot into the system; the other is hardware identification, that is, the amount of power displayed by the phone after the charger is connected.

Usually, the software identification is higher than the voltage recognized by the hardware. Therefore, when we turn on the power, it will display full power. When the charger is connected to the power supply, it is found that it is actually only 80% or lower. Want to be full? Still have to continue to charge for a long time!

In fact, we often do not fully charge the mobile phone, wasting part of the battery capacity, naturally it will feel that the power is falling fast!

Solution:

First check if your phone has virtual power: fully charged when booting, then turn off the power and connect to the charger to see if it is fully charged. If there is virtual power, then turn it off and use it again to see if it will power down quickly!

Case 2: too many background programs, CPU power consumption increases

This old-fashioned question can be ignored. The Android machine is not so good. After the program exits, it will automatically run in the background. And in the case of mobile phones generally no problem, these background programs are often the biggest culprit in power consumption!

There are also screen brightness, wifi, GPS, Bluetooth, etc. of the mobile phone itself, as well as other settings, etc. These seemingly inconspicuous little things are actually big consumers.

Solution:

Regularly clean the background of the mobile phone to solve the unnecessary program to increase the CPU power consumption.

The screen brightness of the mobile phone is turned down. When not in use, turn off the wifi, Bluetooth, etc., turn off the button sound, press the vibration and other power settings.

Think about whether you have installed the program recently, first uninstall it, and see if the power consumption of the mobile phone is back to normal. Many of the small programs that we have neglected actually consume a lot of power!

Case 3: Battery aging

Most of today’s smartphones 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 more and more durable.

If we use the mobile phone battery incorrectly every day, it will easily cause the battery to age and the battery life will decrease.

Solution:

Proper use of the mobile phone battery is the way to extend battery life.

The question to be solved now is, how do we judge whether the mobile phone battery is aging?

If the battery has been in use for a year or so, you can use the usual habits, the phone is fully charged, and the power consumption is also fast, it is likely to have begun to age.

Check to see if the battery has a drum kit. If there is a drum kit, it means that it is not just aging, but the battery is no longer usable. For safety reasons, change the battery quickly.

After the phone has been used for a period of time, the battery body has been hot all the time, so change the battery as soon as possible.

Situation 4: improper brushing

In order to obtain ROOT authority or other various factors, many people will quickly brush up the 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 troublesome!

In this case, it is generally that the brush machine is not complete, resulting in a program error, and then will continue to run the program repeatedly, the power consumption will naturally speed up!

Solution:

The major brushing systems may have some defects more or less, unable to call some of the programs on the mobile phone hardware, and then these programs will be tried repeatedly, we can not see the surface, only after brushing the machine, found problems when using the phone, Will know!

At this time, it is best to find someone to help re-flash, brush back to the original system or the official ROM system, and then manage the system boot and self-start software, you can solve it perfectly.

Case 5: Short circuit and leakage of mobile phone motherboard

For those who are familiar with mobile phone hardware, you can manually remove it to see if the motherboard of the mobile phone is in poor contact with a certain chip capacitor, resulting in a short circuit, causing the phone to heat up, and then check to see if there is any leakage.

Of course, this must be done by professionals, and it is more difficult for the average person to do it.

Solution:

Get the mobile phone after-sales service point to test, or go to some regular mobile phone repair shop, let the professional test you, determine the problem, then the right medicine!

Seven, mobile phone power consumption can also try the following methods

Don’t let the battery run out

The mobile phone battery is fully charged and then consumed, so cycle to avoid the “memory effect.” In fact, this method is only applicable to nickel-cadmium or nickel-hydrogen batteries, not to lithium batteries. Most of the current smart phones use lithium batteries. The author suggests that in order to extend battery life and protect battery health, users should fully charge the phone before the battery is exhausted.

Targeting settings

When users use mobile phones, some LBS-based applications often track the user’s location, which also increases power consumption. Although the power consumption is increased, these application users often use it, and the tracking location enables the application to better serve the user. At this time, the user can find the corresponding application in “Settings” -> “Privacy” -> “Location Service”, and set its allowed access location information to “Use application period”, so that when the application is not used, Save a lot of electricity. Of course, if you don’t need the location service for this app at all, you can set it to “never”.

Better use of WiFi networks

Under normal circumstances, users want to be online 24/7, mobile mobile network is undoubtedly a good choice, but at the same time it means faster power consumption, especially when the mobile phone signal in the user’s area is not good, the mobile phone will search frequently. Carrier signals increase power consumption. At this time, if you can use the WiFi network, the phone does not need to search for signals frequently.

However, the user needs to remember that when leaving the WiFi hotspot, the user can turn off the WiFi connection. In general, it is to let the mobile phone stay in a stable network, without having to search for signals frequently, the mobile phone can save more power.

Proper use of flight mode

Similar to the situation mentioned above, there is no mobile phone or WiFi signal in the subway, such as the high-speed rail, because the mobile phone will continue to search for connections and the power consumption increases. The user can set the phone to flight mode before returning to the signaled location. In addition, turning on the flight mode before going to bed is also a good way to save power.

Low energy mode

If there is no chargeable condition at hand and you want the phone to save power as much as possible, you can consider turning on the low-power mode of the phone. Taking the iPhone as an example, when the battery is only 20% and 10%, the phone will automatically remind the user to turn on the low energy mode.

Low battery mode will temporarily reduce power consumption until your phone is fully charged. When this mode is turned on, see acquisition, background application refresh and automatic download will be disabled, and some visual effects will be weakened or turned off. When the iPhone is charged to 80% capacity, the low power mode will automatically turn off.

Find big power consumers

Now, no matter which mobile phone, you can count the current power consumption in the system. As long as you know who consumes a lot of power, the user can optimize the use. The mobile phone is running out of power. It must be that you have over-utilized an application. iPhone users can use the ‘Battery’ option to get an overview of the applications that used the most power in the past 24 hours and the past week.

Android users can also choose the “Battery” option, which will display a battery usage graph since the last charge and a list of apps that use the most power.
