Smartphone has become an important part of every person’s life today. From the alarm in the morning to the last message at night, the mobile remains in constant use. But in recent times, many users are troubled by a common problem – overheating of the phone. This may seem normal at first glance, but experts recommend not ignoring it.

According to technical experts, the biggest reason for the phone getting hot is its continuous and prolonged use. Video streaming, online gaming, video calls and use of heavy apps put additional pressure on the processor. When the processor works excessively, it produces heat, which the phone’s system cannot completely control.

Heating of the phone during charging is also a common problem. Especially during fast charging, more current flows in the phone, due to which the temperature increases. If the phone is used while charging or a fake charger and cable is used, this problem can become more serious.

Apps running in the background are also an important reason for phone heating. Many apps constantly sync data, track location or send notifications without your knowledge. This has a direct impact on the battery and processor, due to which the phone starts heating up.

Experts also point out that poor network connectivity can increase the temperature of the phone. When the network is weak, the phone searches for signals more frequently, which drains the battery faster and generates heat. This problem is seen more in rural areas or places like basements.

In addition, the phone cover can also play a role in heating. Thick or low quality covers prevent the phone’s heat from escaping. As a result, the heat accumulated inside further increases the temperature of the phone.

Software related problems can also cause phone heating. Old operating system, bugs or not updating on time affects the performance of the phone. Therefore, the updates released by the company should not be ignored.

Experts recommend giving the phone a rest from time to time, not using it while charging, removing unnecessary apps and using only original accessories. If despite this the phone is getting excessively hot, then it is necessary to get it checked from the service center.
