Have you ever noticed that your phone gets hot, but never knew why? Although itâs not uncommon for your phone to get warm when itâs overused, an unusually high temperature may be indicative of a larger problem.
There are a number of reasons for an overheated phone, so itâs important to think through them and figure out what might be causing it so you can ensure that itâs performing well and will last you longer. Read on to learn some of the most common reasons your phone gets hot, how to troubleshoot an overheated phone, and how to prevent overheating in the first place.
Why Do Phones Get Hot? 7 Likely Causes
Various factors cause a phone to get hot and they generally have varying levels of severity. Your phone may be hot from direct sunlight, running too many apps, malware, faulty charging equipment, internal damage, blocked ventilation, or old hardware.
We explain the different causes for an overheated phone to help you understand the problem and prevent it in the future.
1. Warm Environment or Direct Sunlight
If youâve ever left your phone out on a sunny day, you may have been shocked to find out it was very hot to the touch. Direct sunlight is a common culprit of an overheated phoneâso cover your phone from the sun while youâre outdoors.
Aside from prolonged, direct contact with the sun, your phone might also overheat after sitting in a warm environment for long periods of time, such as in your car on a hot summer day.
2. Overloading the Processor
Smartphones are basically just miniature computers, but a key difference between the two is that computers have internal fans to keep them cool and phones do not. Although smartphones are great at diffusing heat for everyday use, thereâs a limit to what they can handle. If you have too much running on your phone at once, it can overload the processor and cause it to overheat.
Below are some examples of what might trigger an overloaded processor:
- Running too many apps at once
- Streaming video content like Netflix or YouTube
- Recording long videos on your phone
- Playing mobile games for an extended period of time
- Sub-optimal settings, like animated wallpapers or widgets
- Keeping your screen brightness on high every time you use it
3. Malware
Sometimes your phone seems to be overheating for no identifiable reason. If you know you havenât left your phone in a warm environment and arenât overloading the phoneâs processor with lots of apps, the issue could be malware on your phone.
Just like desktop computers are susceptible to online viruses and malwareâwhich will sometimes cause the computerâs processor to overload and shut downâthe same can happen to your phone. You may have malware planted in your phone that keeps apps, widgets, and other harmful processes running in the background that strain your phoneâs processor.
When thereâs too much strain on your processor, it gives off more heat. Use this guide to remove malware from your device and to stop it from overheating in the future.
4. Faulty Charging Equipment or Battery
Damaged or faulty chargers, cables, and batteries are capable of heating your phone to dangerous levels. If youâre using charging equipment and notice a burning smell, scorch marks, or melting plastic, stop using it immediately. Be careful not to burn yourself when unplugging it from your phone or the electrical socket.
Replacing your faulty equipment or battery as soon as possible should resolve your overheated phone. Itâs best to only use good quality charging accessories, especially the original cables and chargers if you still have them.
5. Your Phone Has Internal Damage
If your phone has other internal damage aside from the battery, this can cause it to overheat too. Itâs not uncommon to drop your phone, but doing so may result in loose parts that short circuit and overheat your phone. Other damages to your phoneâs thermal paste may render it ineffective at transferring heat from the processor.
6. Blocked Ventilation
Your phone uses its charging port as ventilation, and if this gets blocked by debris, it may cause your phone to get hot. The blocked ventilation in combination with a hot summer day or too much time spent in direct sunlight are likely to make your phone overheat. You can try cleaning the charging port carefully with a cotton swab or toothpick.
7. You Have an Older Phone
Having an older phone also makes it more likely to get hot. Older hardware is likely to have wear and tear on components of your phone, such as the thermal paste of your processor. If the thermal paste is worn off, it will cause your phone to get hot quicker.
Consider taking breaks if you plan to use your phone for a long period of time or turn off features that you donât need to use like Bluetooth to give your processor a break.
How to Diagnose Your Phoneâs Temperature
Itâs important to remember that all phones get hot to some degree, but how do you know when the temperature is cause for concern? Typically, your phoneâs internal temperature will range from 98.6 to 109.4 degrees Fahrenheit when operating normally.
Here are a few tips to figure out if your iPhone or Androidâs temperature is out of the ordinary.
For iPhone users:
Thereâs no way to get a temperature reading on an iPhone, but you can use the Battery Health feature to view information about battery usage and what apps are draining the most battery.
Follow these steps to find out more:
- Go to Settings
- Then choose Battery
- Select Battery Health to view battery usage information
Tip: In Battery Health, check if your battery is worn by looking at the Maximum Capacity and Peak Performance Capability. If itâs operating at less than 100% or isnât operating at normal peak performance, your battery may need replacing.
For Android Users:
Similar to an iPhone, you canât measure the temperature of your Android right from your phone. You can use an app called AIDA64 to give you important details on your phoneâs hardware and software, such as how much RAM youâre using, how fast your CPU is having to run, and how hot your phone is.
Use the steps below to check out the battery usage on your Android.
- Open Settings
- Click on Battery
- Select Battery Usage to see your battery status from the last 24 hours
How to Cool Down Your Phone
If you find yourself with an overheated phone, there are some simple steps you can take to troubleshoot it. Try the following to get your phone back in working order.
Avoid Direct Sunlight
If your phone overheated because it was left out in the sun, remove it from the sunlight as soon as possible. As long as it remains under the sunâs rays, itâs unlikely that it will be able to cool down.
That said, donât put your phone in the freezerâsome think this will bring the phoneâs temperature down faster, but drastically changing the temperature from hot to cold can cause further damage to your phone. Instead, just bring it inside in a cool dry place and leave it alone for a few minutes, and it should return to normal.
Turn On Airplane Mode
Airplane mode can help combat an overheated phone because it turns off all non-essential programs that might be running in the background. This may speed up the cooling process.
Another option is to completely turn your phone off, which is one of the fastest ways you can get your phoneâs temperature back to normal.
Close Out Your Apps and Keep Them Updated
Running a ton of apps in the background can push your phone to its limits. If itâs overheated, close all your apps down until the temperature returns to normal.
Additionally, if you havenât updated your apps in a while, itâs a good idea to do so. Many app updates tackle bug fixes that can improve the efficiency of your phone and keep the processor from overloading in the future.
Take the Case Off
Phone cases are critical for protection from physical damage, but many of them have poor ventilation. They can actually trap the heat in your phone and interfere with it cooling down. If your phone is overheated and you have it in a case, take the case off to help bring the temperature down.
Place It Next to a Fan
If you have access to a fan or a car AC, give your phone access to cool air to speed up the cooling process. Even if you donât have access to a fan, simply blowing on your phone yourself or fanning it with your hands can help it return to a normal temperature more quickly.
How to Prevent Your Phone from Overheating in the Future
If you want to avoid your phone overheating, there are a few simple precautions you can take. Use these preventative measures to stop your phone from getting too hot and becoming unusable.
Keep Your Apps Updated
If your phone has ever overheated for no apparent reason, you may want to investigate some of your apps. One or more of them could have a bug thatâs causing your phone to overheat. To keep your phone performing optimally overall and to prevent overheating in the future, itâs best to always keep your apps and phone settings updated.
Purge Unused Apps
Unused apps running in the background cause your phone to work harder than it has to and strains the battery and phone processor. This can result in overheating. Itâs a good idea to regularly clean out your phone of any unused apps or downloads that are weighing your phoneâs processor down to prevent overheating in the future.
Charge Your Phone Correctly
Did you know that using your phone while itâs charging causes your phone to produce more heat? You can prevent an overheated phone by leaving your phone alone while itâs charging.
In addition to this, using the incorrect charger for your phone can also contribute to overheating.
Some chargers are designed for stronger phones, and if you use a charger thatâs not suited for your particular phone model it can cause battery damage and overheating. The main thing to make sure of is that the input of your phone is the same as the output of the charging adapter youâre using.
Turn Off Unnecessary Settings
Certain phone settings, like high brightness, GPS, or Bluetooth, can keep your phoneâs battery processor in overdrive unnecessarily and lead to overheating. To avoid this, remember to turn energy-draining settings off to preserve your phoneâs energy and keep it cool.
Use an Antivirus Software
Sometimes overheating is caused by malware thatâs been downloaded on your phone or bugs in your apps. Using antivirus software is one of the best ways to protect your phone from overheating as well as from data and security breaches.
While antivirus software is already built into iPhones, Android users can benefit from a mobile antivirus that detects viruses, malware, and other threats that might compromise your phone. Panda Security offers a free antivirus software for Android that can work for your phone and tablets.
While an overheated phone may seem like cause for concern, it usually takes a quick fix to get your phone back in working order. Donât leave your phone out in hot environments and limit how many apps and programs you have running on your phone at once to avoid overheating.
Most importantly, protect yourself from malware and other cyber threats by having the proper antivirus software installed on your smartphone and computer.
