First, the cause of mobile phone fever
< br >
Battery reasons, running too many large programs so that the CPU load is high, internal components damage.

1, 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, the mobile phone heat is larger.
< br >
2, multiple background applications run together, resulting in CPU overload, the current thermal effect can be imagined, and the theme, background, screen saver, which are large users of electricity, resulting in mobile phone fever. Especially in the case of navigation, games, and video operation, these programs will open gps navigation, Bluetooth, wifi, or hot spots when running, which is very easy to cause serious heat.

3, when the user uses the mobile phone Internet, when the data transmission is more, the greater the power consumption, the CPU usage will increase, the heat is large.
< br >
4, the power consumption of mobile phones in long-term calls or the use of audio and video is very large, that is, the equivalent load resistance of its battery is small, and it is a large current discharge when working. After the battery is discharged, the internal resistance increases, but the current required for the work of the mobile phone cannot be reduced, so a considerable part of the energy is consumed in the internal resistance of the battery, resulting in battery heat.

5, because people are used to holding the mobile phone, resulting in the mobile phone can not heat. If you use your phone for a long time and the heat dissipation is not good, it will also cause the phone to heat up.
< br >
6, the use of non-original charger charging, resulting in mobile phone fever, such a charger lack of 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 risk of explosion.
< br >
7, when charging the mobile phone, the battery itself is charging, the battery will have a fever phenomenon, such as phone calls, playing games and so on will increase the fever, if the day is hot and the mobile phone with a case, the mobile phone is very easy to hot, with a thick mobile phone cover is also easy to heat.

8, the hardware or battery failure of the phone itself will also cause hot, but this type of situation is generally less.
After all, this is the use of TSMC seven-nanometer process processing processor, its performance is very powerful, of course, its power consumption is also very terrible, but compared with Qualcomm Snapdragon 888 processor, its power control is quite excellent, but compared with Qualcomm Snapdragon 865, its power consumption is still quite large, after all, its performance has improved a lot.
Hello, the subject
First of all, to explain which phone you are using with Snapdragon 870, different models of the heat dissipation system is different, so the operating temperature of the phone is not the same at the same time.
Secondly, today is the hot summer temperature is high, the temperature of the surrounding environment will also directly affect the problem of mobile phones, especially in the high temperature environment using mobile phones is easier to heat.
At the same time, the use of mobile phones will also affect the change in temperature, so it is necessary to analyze specific problems.
Snapdragon 870 is based on TSMC. Made by 7nm process, including one A77 (3.19GHz) super core, three A77 (2.42GHz) large core and four A55 (1.8GHz) performance core, other aspects such as Adreno 650 and X55 5G The baseband has not changed, but the WIFI chip is only supported to FastConnect 6800.
