A physics professor listed the common causes of phone overheating

The smartphone can heat up even when the screen is turned off and without charging. Alexey Yurasov, Doctor of Physico-Mathematical Sciences, Professor of the Department of Nanoelectronics at RTU MIREA, told about this on Wednesday, November 11.

In conversation with Lenta.Ru The specialist noted that background processes are most often the cause: updating applications, synchronizing data, processing photos and creating backups. Increased processor load increases power consumption and heat generation. This happens especially often after updating the operating system or transferring data to a new phone.

Heating may also be associated with a weak mobile network signal. In such conditions, the device uses more energy to search for base stations. You can check the cause using airplane mode: if the smartphone starts to cool down, the problem may lie in the operation of the radio module. In addition, overheating is caused by direct sunlight, tight covers and poor ventilation.

Yurasov warned that constant heating combined with rapid discharge may indicate a malfunction of the battery or power supply circuits. Battery damage can lead to fire in severe cases.

If the temperature rises inexplicably, the expert recommends checking the battery consumption, restarting the smartphone, updating the software and limiting the background activity of applications. If the case is very hot, stop using the device, remove the case and let it cool down at room temperature. In case of regular overheating, rapid discharge or spontaneous shutdowns, it is necessary to find out the cause of the malfunction before continuing operation, writes NSN.

How much have sales of these gadgets increased and which models do Russians choose?

In late October, analyst Stanislav Yanchev warned that unknown applications, suspicious account logins, and actions without the owner's knowledge may indicate hacking of a smartphone. Rapid battery discharge, slow operation, and overheating of the device are not necessarily associated with infection, but if these problems appear along with other signs of hacking. It is worth conducting a deep check of the gadget, according to 360.ru .

Also in October, expert Vladimir Zuev, in an interview with RT, urged not to leave the extension cord plugged in at night. He explained that damaged insulation is a direct path to a short circuit, which can occur at any time, including at night when a person is sleeping.

In July, information security expert Alexey Gorelkin told Moscow 24 that there are practically no devices on the market right now that are prone to overheating, explosions and similar incidents. In his opinion, the problem in such situations often lies not in the technology itself, but in the chargers, wires or cases.

In June, expert Alexey Dviliansky told the Moscow City News agency that before handing over an overheated smartphone for repair, confidential data should be deleted and important accounts logged out to avoid leakage of personal information.

At the same time, expert Natalia Golitsyna noted that at high temperatures, especially above 35 degrees, the phone may work unstable, as overheating makes it difficult to remove heat and in some cases leads to its automatic shutdown.
