What are the causes of cell phone heating

Sihai network: the fast heating and power consumption of the machine is a big problem that puzzles many mobile phone users. It is not only hot, but also the navigation software is slow to use, card or even stagnant. In our daily use, what causes the cell phone to heat up? What can be solved quickly when the mobile phone is hot?

Causes of cell phone fever

1. Signal problem: 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 power of the cell phone is high, and the cell phone is also hot.

2. Program operation: multiple background applications run together, resulting in CPU overload, and the thermal effect of the current generated can be imagined, and the theme, background, Screensaver are all large users, resulting in phone heating. Especially in the case of navigation, game and video operation, these programs will turn on GPS navigation, Bluetooth, WiFi or hotspot when they are running, which is very easy to cause serious fever.

3. Data transmission: when users use mobile phones to access the Internet and have more data transmission, the greater the power consumption, the greater the CPU utilization, and the greater the heat output.

4. Long time audio and video or call: the power consumption of mobile phone during long-time call or use of audio and video is very large, and the battery of mobile phone is discharged with large current when working. After a part of the battery is discharged, the internal resistance increases, but the working current cannot be reduced, so a considerable part of the energy is consumed in the internal resistance of the battery, resulting in the battery heating.

5. Usage habits: because people are used to holding the mobile phone with their hands, the mobile phone can not dissipate heat. Long time use of mobile phones and poor heat dissipation will also cause the phone to heat up.

6. Non original charger: use non original charger to charge, resulting in phone heating. Such charger lacks protection circuit, cannot guarantee the stability of current when charging, and is easy to burn the battery, shorten the service life of the battery, and even has the risk of explosion.

7. Charging and playing with mobile phone: when the battery is charged, the battery will generate heat, such as making phone calls and playing games, which will aggravate the occurrence of heat. If the weather is hot and the mobile phone has a cover, the mobile phone is very easy to burn, and the thick mobile phone cover is also easy to generate heat.

8. Hardware or battery failure of the mobile phone itself: it can also cause scalding, but generally this kind of situation is less. If your mobile phone has two batteries, change another battery to see if it's still hot. If it's no longer hot, it's the problem of the battery. If it's still hot, close some running large programs and some programs that can't be used. If the mobile phone is still hot, it should be sent for maintenance considering the damage of internal components.

Solution to mobile phone fever

1) If possible, physical cooling. Put it in the air vent of the air conditioner or throw it into the refrigerator to cool down in an emergency. When the temperature drops, it won't hurt the phone itself. Check what power consumption program is turned on and turn it off.

2) When it's already hot, turn it off immediately. After shutdown, it is equivalent to killing all programs, and then starting up after the temperature drops.

3) When the trend of heating is large, GPS positioning, WiFi, Bluetooth and even direct flight mode can be turned off. Or if you've been playing games for a long time, take a break.

4) In other cases, if you unplug the charging line, remove the case, or it's hot, let the phone rest.
