Your smartphone should slightly heat up while in use; this shouldn’t be a cause for alarm. You should be bothered when the change in temperature affects the performance or productivity of your device.

For any machine to operate, it requires a process to run. From the start up point of being switched on, to when you require the machine to perform a task, till it gets to a “switched-off” mode, it is constantly on a systematic process that enables it to carry out any task required of it. This process also applies to the smartphone.

Smartphone manufacturers constantly upgrade their smartphone hardware to meet new market trends. With the latest operating systems, processors, RAM and ROM size, the slimmer designs that we have in the markets today, and of course the shorter cycles to introducing the newer models. This makes it almost certain that some production flaws will be associated with these smartphones, in areas such as inconsistency between software and hardware phone operations, performance lagging, and overheating.

This leads to the question; “Should I be worried when my smart device overheats?” The short answer is “No”. The reason is that you can ascertain the cause(s) in the first place and you can adopt measures to prevent it.

We will go through some major reasons why smartphones overheat. We will also let you in on ways to prevent overheating. Keep reading…

Causes of Smartphone Overheating and ways to prevent it

1. Using your phone while it is being charged

This can be regarded as the leading cause of overheating in most smartphones.  Smartphones shouldn’t be in use while it is being charged. Apart from the hazardous effect that is associated with using the phone while charging, the smartphone’s circuitry is also constantly open with charges going through it. This is not a good idea. In addition, once your smartphone has attained the ‘fully charged’ status, it should be unplugged.

Another good practice is to charge your device only when the battery power is flat, and not just whenever there is electricity even when the battery is not running low.

Your device should also be kept on a flat strong surface while charging, instead of being kept on a bed or sofa.

2. Continuous Usage and Multi-tasking

Continuous usage is one of the major reasons why smartphones heat up. Several apps run while you are using your device, not to forget the apps that run in the background. These apps running in the background make the processing power drain out, and in turn, it causes overheating of the device.

So, the best way to prevent the overheating which comes with continuous usage and multi-tasking, is to close the apps, and let your smartphone breathe.

 3.Bad Ventilation

Direct sunlight is a reason anything, or even anyone, can have a high temperature. So, why not smartphones? If your device is always exposed to direct sunlight and wet environment, then you make your device susceptible to overheating or liquid damage, respectively. To prevent either of these from happening, always keep your device in a well-ventilated environment, free from direct sunlight or liquid spill.

4. Third-party chargers and faulty batteries

Faulty batteries and some third-party chargers can be responsible for overheating. Different chargers are made to different wattage and different smartphones are made to work on different wattage. This is also a factor to consider when using a charger or getting a new battery.

Ensure your chargers and batteries are made for your device, and are also made by the original equipment manufacturer.

5.  Phone Case Usage

Using a phone case is a safety measure that we highly recommend at BM Academy. But then again, one should be careful because keeping the phone in a case always, traps the heat from the handset.

Removing the phone case from time to time can reduce overheating to an extent.
