Are you receiving an error message that your phone is too hot? Is it overheating and hot to the touch? When your phone senses hot to the touch, there’s a reason and consequences for using it continuously, all day.

In today’s world, it is very occasional that someone doesn’t have a phone. From ancestors to their grandchildren, every member of the family owns a phone and uses it for various purposes. 

The only usual use of these phones is to make calls, or else someone uses it for office tasks, somebody likes taking pictures, little ones want to play games on their phones and many other responsibilities depending on who is using it.

Because of heavy processing or playing high-end games, the chipset begins heating up and causes anxiety while holding the device in hand or resting it on the ear. 

Inside your phone, the processor, camera, screen, battery, and other parts can create a lot of heat when they are in use, just like a standard computer.

While computers and laptops have fans to cool them down, cell phones don’t. As a substitute, they use a distinct coating on the circuits inside to better diffuse heat. So many times, when your phone is working well, it will not give off too much heat, and you ’ll be able to keep it normally.

Unfortunately, there is no single answer to this question. Sometimes phones get hot as the outcome of too many apps running in the background. A corrupt battery or other hardware complications cannot be ruled out. Sometimes, it may be because of the malware infections your smartphone may face and making it hot so fast.

But just to help you understand whether your phone is heating up unusually or if it is all good, we will tell you the causes why your phone might be heating up. Also, we are going to propose several methods to cool down your device.

Finding the Culprit

There are some signs you can use to conclude why your phone is heating up. First, heating can be caused by defective hardware, but it can also be initiated by software glitches. Three main areas in a phone produce heat: the battery, CPU, and screen.

When a phone becomes hot, the battery is typically the first place to look. If the heat is coming out from the back of the phone. Recent lithium-ion batteries are exceptionally powerful, which is why they sometimes get hot. The temperature causes the battery to vent its organic solvents which could essentially ignite from too much heat or a flash.

If the heat is coming out from the front of the screen, however, it may be as a result of the phone’s CPU or GPU. Both of these components generate heat as a by-product of operation, so when the processor is in demand, the heat production increases consequently.

Similarly, if you are detecting heat coming from the bottom of your phone, there is a very good casual; there is an issue with the charging unit.

Hot Environment or Exposing your Phone to Direct Sunlight

If you have ever left your phone on a cloth at the beach or sitting on a table in the happy sun, you know just how rapidly those UV rays can overheat it.


One probable reason your phone feels hot is that it’s been visible to direct sunlight or some other heat source for too long. You might have left it in the car on a hot summer day, for example.

This kind of overheating can be a severe problem. Likewise, direct heat like this can potentially damage your phone’s inner components, impact battery life and charge time, slow down functioning, and even crack your phone’s screen, According to The Guardian newspaper.

Be cautious where you leave your phone for long periods, mainly in hot weather. When your headset gets too hot from the sun, find a cool, shady place to leave it while its temperature comes down.

Extreme Use of Screen or Processing Power

Mobile phones are great at dispersing heat from regular use so you do not burn your hands while using them, but they have a perimeter to what they can handle. Finally, they don’t have a high-speed fan inside them like more powerful processors require.

If your phone hasn’t been in a hot atmosphere or direct sun, but it’s badly overheating, there’s a great chance that your phone has been asked to use too much processing power or release too much light from its screen.

Here are a couple of main offenders that could be causing your phone to get so hot:

  • You are running too many apps
  • You’ve been playing gaming for too long
  • You’ve been watching Netflix, YouTube, or other video content
  • You’ve been surfing with the screen brightness cranked up too high
  • You’ve been linked to a Bluetooth device or Wi-Fi for too long
  • You’ve been taking several pictures or long videos with the camera

In these circumstances, there’s probably nothing extremely wrong — your phone just needs a bit of a pause to cool down. It’ll be ready to use again before you know it.

Battery Issue

The battery is another cause that leads to extreme heating, especially in slim and metallic phones. Heating in Li-ion batteries also suffers from a phenomenon called ‘thermal runaways’ which means they will disperse even more heat when heated.

Applications and Operating System Issues

Certain bugs in apps can be the cause of your phone to overheat or misbehave. The same happens for your phone’s OS. Because these apps have to run on various types of devices using diverse configurations and operating systems, they may act optimally on some, less so on others.

The better way to stop them from malfunctioning is to keep them updated. Here are some good helping guidelines to follow to make your phone cool down.

Cooling down your Phone

More often, the reason your phone heats up is due to several different reasons, not just with a single one. Here are some tips to assist you to drop the temperature.

First, never keep the phone in the freezer. Quickly introducing your phone to radically different temperature ranges can cause the screen to crack and the system to experience hardware problems. Also, putting a phone in the fridge will cause condensation both in and out of its case, which can harm electronic components.

Better Suggestions Include:

Your case is a common heat reason that many smartphone owners overlook. Many cases are created from plastic or have a large amount of plastic. Even those prepared with leather have the same problem: the phone is insulated, keeping the heat in and cold out.

Removing the Case

For safety reasons, as the phone becomes hot (mainly during high-performance tasks), it needs to discharge the heat away, and the presence of a case made from an insulating material prevents this. It’s just like exercising in a duffel coat.

Your choices here aren’t great, however. Taking out your phone from the case is a good start, but if you’re awkward with this (perhaps taking extra care to maintain its resell value), then it is not a practical long-term option.

Turning off Needless Settings

Frequently, people leave GPS, Bluetooth, or Wi-Fi options turned on, even when they do not require them. Turning off extra apps can end overheating and save battery life. Better still, turn on Airplane Mode when you don’t want to use your phone.

Checking the Battery Regularly

Sometimes you just have a corrupt battery. If the battery itself seems like it’s regularly overheating, then it may be time to pick up a new one. If you take out your battery and observe that it’s warped, bloated, or — especially — leaking, then it’s certainly time to change.

Similarly, if you see that your battery life just isn’t what it used to be, no matter what you have turned on or off, then it may be time to chunk it and look for a new one.

Slowing Down That Gaming and Chatting

A usual way device overheats when they are overworked, especially when high graphic games and apps are constantly running on the device. These apps can eat at your phone’s RAM, CPU, and GPU, compelling the battery to work harder than normal.

A good guideline when playing games and using applications that keep your phone’s processing power is to take a 20 to 30-minute pause every one to two hours after opening these apps.

Inspecting Your Battery and Charger Cable

Another side to consider is the state of your battery and the charging cable. If you have an old phone that has been overcharged several times (you should never charge to 100% if you can support it; regularly charge to 80-90% to keep the battery healthy), then smartphone overheating can happen. Our instructions on improving smartphone battery life should help here.


So all you need is just to recall that a cool phone is a happy phone, and by doing a few simple things, you cannot only maximize the quality of life for your phone and battery but maybe the quality of your life as well.
