Smartphone overheating - Causes and possible fixes

We have been hearing a lot these days about overheating of smartphones. Such excessive overheating has led to burn injuries too in some exceptional and extreme cases. In this context, we need to have an insight into what exactly causes this overheating. Let us analyse a few reasons for the occurrence and how we can minimise it.

Smartphones have turned into being necessities nowadays from being a luxury just a few years ago. Excessive demand on the resources has raised the performance level of the devices. At the same time, it has given rise to certain issues too. Overheating is one of them. Let us make an attempt to find the reasons that can cause your phone to overheat and discuss about the possible measures you can employ in an attempt to minimise such occurrence.

To begin with, we will analyse the possible causes for the overheating issue. As a matter of fact, we have come out of an age where phones were meant for communicating via voice calls. The smartphones today have become Universal Devices. What I mean by this term is your smartphone now does - or more precisely, you want it to - carry the collective responsibility of all your older devices. It is your music player, your digital camera, your laptop and what not. Such overburden is bound to have certain effects.


Extensive Gaming

One of the most important causes for a smartphone to heat up is how it is being used. Tendency to practice excessive gaming is one of the prime examples. You need to remember that your smartphone is NOT comparable to your gaming console. Playing a resource hungry can be quite taxing for the motherboard.

Internet browsing

Indulging in excessive web browsing can be harmful for the device. Surveys have shown that this is the second largest cause for the overheating issues. The phone needs to double efforts while browsing on a mobile data - be it Edge, 3G or 4G. It needs to support the data network and at the same time has to use the resources to show you the results.

Lack of Ventilation

Since your smartphone is is so small in size, it lacks proper ventilation. All our gadgets and gizmos have heating issues, but being huge in size - they are well ventilated. Same goes true for your TV, PC or Laptop. The handset you are using keeps waiting for that "Breathing Space" which it does not get! The problem gets more aggravated with the demand for the leaner and thinner devices. In an attempt to make their phones thinner than the competitors, smartphone manufacturers do not pay any attention to the dissipation of the heat generated.

Faulty batteries

Most of the time, we tend to forget that the battery that powers your smartphone is not an integral part of your device. You need to CHANGE it after a certain period. None of the smartphone manufacturers educate the buyers about the havoc that an old battery can play. A standard Li-ion battery is capable of around 500 charge - discharge cycles ( this is the maximum value I am talking about, some batteries may have a 300 charge cycles). If you have the habit of charging your phone once everyday, you may need to replace the battery after about two years after your purchase.
Your phone may also have some other malfunctioning components which have a tendency to heat up.

Unhealthy charging habits

We know that you can use your phone while being charged. But you should not be tempted to do it all the time. Such an exercise can cause your battery to get shortened. It may also result in unnecessary stress on other components of your phone like processor.

Probable solutions to overheating

Disable unwanted processes

Some of the functions your smartphone offers are taxing on the battery. Many such processes keep running in the background even if your phone stays idle. You can disable such apps and background processes you do not need. Lower the screen brightness. Turn of the Auto Brightness when you are indoors. You do not need to keep the features like WiFi, Bluetooth or GPS turned on even when you are not using them. If you are rooted, you may use apps like Greenify for the purpose.

Take care of your batteries

If you need to replace batteries, go for reliable ones. Using a genuine battery will always be good idea. There are some brands which provide better quality. You can opt for the ones from Mugen and Hyperion among others. Never ever go for low priced batteries. E-commerce sites are filled with such products. They may not give you the same backup as the original batteries. Avoid draining your battery fully before plugging it into charging. Partial charging tends to make your battery last longer.

Have a limit on your tasks

Extensive gaming and web browsing are more prone to overheating. These tasks tend to be exhausting for the hardware - especially the processor. Control the time spent on such activities. Make sure you close the running apps while multitasking. Most of the times while working on the phone with one app, we tend to open another one to check for some information. Once done, we just press the home button and continue with our task. Be sure to close every app you opened from app specific exit button.

Reboot your phone regularly

Make it a habit to restart your phone at least once in a day. Rebooting always solves most of the problems with your phone. Though it may appear as a simple and silly solution, it works wonders at times.

Clear Cache

Some corrupt cache memory can result in overheating of your device. Once you delete the cache files, the phone creates a new cache file which solves the issue. This becomes more important when you have uninstalled an application. Though the app has been uninstalled, it may leave some orphaned files back. Such files can cause the malfunction.

Check your SD card

A faulty SD card can cause overheating issues. Remove the memory card and try running your phone without it or a couple of hours. You may check it with some other memory card if you have a spare one.

Care while charging

If your charging habits are not proper, it can result in malfunctioning batteries, which in turn can cause overheating. Use original chargers for charging your device. Do not perform extensive tasks while your phone is being charged. Also ensure proper ventilation at the place where you charge your phone.

Handle your device carefully

We have a tendency of practically throwing our phones anywhere. Do not just leave it in the car where it burns under the heat from the car and bright sunlight. Leaving it aside another electronic equipment can make it suffer magnetization effects. Taking proper care for your device may be much helpful in reducing overheating issues.

Clean your device

Keep your device clean. Cleaning the battery contacts by puffing air can help remove accumulated dust. Clean the ports. Take care not to damage the contacts.

Parting Words

Well, I hope to have made an attempt at minimising the overheating issues in a smartphone. Most of the above suggestions assume the heat generation caused by improper usage of the device. It should be noted that some phones suffer from internal hardware issues that cause overheating. Only solution in such cases would be getting it repaired or replacing the phone. Apart from such extreme cases, I would wish to find a few comments from readers with a few more tips on avoiding overheating.
