Reasons for Your Phone Overheating Too Much

One of the common problems when using phones, which has existed from the past until today, is the phone overheating—whether slightly or severely. Overall, a hot phone does not give a pleasant feeling to the user and can sometimes be a sign of a danger threatening the phone’s processor and battery. However, it is normal for any of our phones to get hot at times. So, what factors cause a phone to overheat? In this report from the technology section of Namnak, we will introduce you to 6 important reasons behind phone overheating.

1. Excessive Phone Usage
   Don’t get it wrong! We don’t mean just the amount of time you spend holding and using the phone. Although time matters, it is not the main factor. What we mean here is running multiple heavy apps simultaneously and switching between them. For example, if your phone has 4GB of RAM, it is very likely that up to 90% of it could be filled, causing lag and severe overheating. This indicates that you have used the phone beyond its capability.

   

   If your phone overheats in this situation, there’s no need to worry. It is recommended to close the multiple apps you’ve opened and let the phone sit for a few minutes to return to room temperature.

2. Bugs in the Phone’s Operating System
   Sometimes, your phone’s operating system may have bugs, which can cause the phone to overheat. Therefore, it is always recommended to download and install the latest updates for your phone’s OS to prevent such bugs from making your device vulnerable to hackers. Another point to note, which has existed for many years, is the security difference between Android and iOS.

   

   Android OS is less secure compared to Apple’s iOS and is more prone to malware and hacker attacks. On the other hand, Apple’s iOS has high security. So, if you can afford a phone with iOS and value security, it is recommended to choose iOS.

3. Battery, Charging Cable, or Charger Issues
   This may seem simple but is actually more dangerous than it appears. If your charger or cable has even minor or major defects and you continue using it, it may not deliver the proper voltage to your battery. For instance, if your battery requires a 25V charger but your damaged charger only delivers 5V due to faults, the battery will not receive sufficient voltage and will start overheating.

   

   Initially, this overheating can make the processor and other hardware warm, which, over time, can damage the hardware. It also reduces battery life, eventually leading to battery failure, swelling, and making it unusable. Therefore, if you notice your charger is no longer safe to use due to minor damage, it is recommended to replace it.

4. Damage to Phone Hardware
   As mentioned earlier, frequent overheating can damage your phone’s hardware. When hardware is damaged, you may experience minor technical problems such as lag, severe slowdown, frequent overheating, or even the phone getting hot when not in use. It is recommended to consult a technician with expertise to check your phone’s hardware.

   

5. Old Phone Model
   Another important factor affecting overheating is an old phone. Hardware age has more impact than many realize. For example, if you are using a phone designed in 2014, apps back then were designed according to the specifications of phones from that year. A phone with 2GB RAM could easily run WhatsApp at that time.

   

   However, today WhatsApp has advanced significantly with more features. If you want smooth performance, a 2014 phone’s RAM will no longer be sufficient, causing heavy processing and overheating. (WhatsApp is just an example; the principle applies to modern apps in general.) So, if your old phone frequently overheats, it is likely due to aging hardware.

6. Malware Infection
   Another important point is that your phone might be infected with malware. You may have ignored warnings about not clicking unknown links, not installing unknown apps, or not downloading suspicious files. If so, your phone is likely infected. It is recommended to use genuine antivirus programs with a valid license to protect your phone.
