Causes the phone to heat up
The battery causes too many large programs to run, causing high CPU load and internal component damage.
1. When the mobile phone number strength is -75dBm, the signal strength will become 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.
2. 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.
3. When the user uses the mobile phone to access the Internet, when the data is transmitted for a long time, the power consumption is increased, the CPU usage rate is also increased, and the heat generation is large.
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, the equivalent load resistance of the battery is small, and the current is a large current discharge. 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.
5, 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.
6, 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.
Battery cause solution
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.
1. When the mobile phone is at normal room temperature, the heat does not exceed 50 °C. It is normal. When the phone is very hot, remove the battery back cover and force heat dissipation.
2, it is best to use the original charger, and it is best not to play the phone when charging.
3, 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.
4. 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 (lithium battery)
5. When using a mobile phone to listen to MP3 or battery charging, if the phone feels a bit hot, if it exceeds 50 °C, immediately return to the standby state or use a replacement battery. If charging, immediately unplug the charger.
6, 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.
