What to do if the phone is overheating?
An overheat smartphone usually run slowly, run out of battery fast, shorten its life span, or even explode. So, take it seriously once your phone is extremely hot.
#1. DON’T leave your phone in the sunlight too long.
In other words, avoid using your cell phone at high temperature. Sunlight, especially summer’s sunlight, will heat up your mobile phone if you put it under sun directly for a long time.
If the phone is extremely hot in sun, stop using it and move it to cold it, do not use the phone until it cools down. The phone will cool down faster after taking the protective case off.
#2. Close hardly used programs in the background.
You may don’t know so many apps are running on phone background, as you haven’t used any of them. These apps not only consume RAM storage, but also consume battery power, and generate heat in long time processing.
The program isn’t closed if you tape Home button to back home page, it will run in the background. Generally, tape the return button twice to close the program, or click Exit from the app menu to quit running the program. Certainly, you may forget to end the app, or haven’t time to quit the app. In this case, you can check your phone frequently and close the apps at one time.
#3. Stop using the phone if you have used it too long.
People are easy to addict to their mobile phones so that often forget the time when using the phones, or continue to play with the phones while charging . It’s no doubt that long time of using and using while charging will make the phone gets hot. For example, the heat arise when you play game or make a call for a long time, because a game requires many parts of phone work at the same time and thus the phone’s CPU cannot meet your demand.
Stop using your phone when you feel it’s hot. If you can’t control yourself, just download an app like Offtime, Moment to restrict the using time.
#4. Remove malware from your phone.
Malware goes wherever they can, so be careful with them when using your mobile phone. When your cell phone is infected by the virus or other types of malware, it will spread malicious content, send your data to the malware developer by using the phone’s resources. Thus, your phone gets heat suddenly.
Therefore, run the virus scan tool on your phone to find the malware source, then uninstall the app. However, though the phone hasn’t infected by malware, you should remember:
● Download apps from an official site or known market store, instead of unknown source.
● Do not click pop up advertisement while surfing the internet.
● Do not click unsafe, strange links from others.
● Install an anti-malware tool and scan your phone frequently.
#5. Update the firmware and apps to the latest version.
Developers are dedicated to offering their users new firmware version, because outdated apps or software run inefficiently or have some bugs which overuse the cell phone’s processor and thus cause your phone overheats.
Update your apps: head to the app store on your phone, click your Account, check if there are any available updates for your downloaded apps. Generally, when you open an app, it will notify you to update the app if it has a new version.
#6. Avoid using your phone while the signal is poor.
If your phone’s signal is poor, the phone will change to a better network type automatically, and struggle to find strong signal while you are surfing the internet, which results in the mobile works harder and begins to heat up.
Avoid surfing the internet or making a call when the signal is poor. If you are urged to call someone, the easiest way to obtain better signal is to change a place to check if you get better reception.
#7. Charge your Android phone properly.
If the overheating problem is caused by phone battery, the back of your mobile phone will be obvious hot. Press and hold the power key to turn off the phone, then check your phone battery temperature. Android phone battery’s temperature is about 30 centidegree, sometimes go up to 40 centidegree. You could check the battery temperature of your smartphone in settings:
There are two main reasons that why the battery is overheating: you charge the phone with improper charging cable, or the phone is too old. Charge your phone with its original charging cable or branded USB cable . If the battery is overheating though you didn’t use the phone for long, maybe the battery is aging seriously. Therefore, you should replace a battery for your phone, or just purchase a new mobile phone.
Wrap up
Above are some common reasons and solutions for resolving a hot Android phone. However, the overheating problem can be caused by personal settings, which you can try disabling unneeded features and functions, and restart your phone (or factory reset) to fix the problem.
The solutions work on almost all Android phones. If the overheating problem cannot be fixed by trying all above methods, go to a local mobile phone repair shop or contact the seller to solve the problem.
What to Do If Your Phone Is Overheating
Here’s why smartphones overheat, and several steps you can take to help cool things down.
Heat is your phone’s worst enemy. Modern smartphones house powerful processors and large-capacity batteries inside slim cases, which make overheating a real concern, even under normal operating conditions (looking at you, Galaxy Note 7). Whether it’s charging, sitting idle, or performing more active tasks, your phone has a safe internal temperature it needs to maintain, lest it end up shorting out, catching fire, or even exploding.
Sometimes, internal defects can lead to major problems, other times it’s the way we treat our phones that dictate how long they last. Whatever the reason, if your phone overheats, there are a few steps you can take to help cool things down and prevent it from happening again.
What Temperature Should My Phone Be?
Smartphone manufacturers recommend you keep your device between 32-95 degrees Fahrenheit/0 to 35 degrees Celsius when it’s charging, performing tasks, or sitting idle. It may run hotter than that if you’ve been playing games, streaming video, or mirroring your screen for hours, or you’re synching a huge amount of data to the cloud, restoring from backup, or using graphics-intensive or augmented-reality apps or features, among other things.
Unfortunately, there is no easy way to check your device’s internal temperature. In the past, some phones displayed this information within the settings menu, but that is no longer the case. Instead, you’ll need a third-party app for a reliable look at the internal goings-on of your phone.
What to Look Out For
While phones have CPUs like your computer, they do not have internal fans to keep temperatures down, largely because phones aren’t doing as labor-intensive tasks as PCs. Modern smartphones will help you out here by posting a warning on the screen if the device gets too hot. It may also shut down certain features in order to help it cool down. But it’s a bad idea to rely on these warnings; exposing your phone to high temperatures on a regular basis can permanently damage it.
Be Careful Where You Place Your Phone
It may seem silly, but take note of where you place your phone when it’s charging. Since connecting it to power will naturally increase the temperature of the device, keep your phone free of any clutter. Don’t charge it in bed, or bury it under pillows, blankets, papers, or books. Your smartphone should instead sit on a hard, flat surface as much as possible.
Unplug and Restart
Has your phone become uncomfortably hot (but not so much that you can’t handle it)? It should go without saying, but don’t put it in the freezer. Sudden shifts in temperature can seriously damage the phone because the components inside your device expand when they heat up, so introducing intense cold can add unwanted moisture to the phone.
Instead, unplug your phone if it’s charging. Then, power it down, and let it sit in a cool place, away from direct sunlight or any heat sources, such as a radiator. If you have a phone case on the device, remove it.
Try a Different Charger
If the device was just charging, check for any damage. Is the cable melted or shredded to the point where you can see the internal wiring? Dispose of it safely and use one without damage.
Even if there’s nothing physically wrong with the charger, double-check that it’s from a reputable brand. Ideally, you’ll only charge your phone with the charger that comes in the box. But if your new iPhone or Galaxy phone didn’t come with one, make sure the charger was made by Apple or Samsung, or stick with a known brand, such as Anker.
Cheap alternatives from no-name companies sold online are not safe; the potential hazards are not worth the few bucks you might save. If you’re not sure what to look for, Apple has a whole page dedicated to identifying fake MFi chargers for the iPhone.
Put Offending Apps to Sleep
Your device’s CPU works hard to process games, augmented reality features, and even GPS navigation. If the phone is heating up while running one of these apps, force-close the program and give your device a break.
Even if you are not actively using an app, it can still be running in the background and putting pressure on the CPU. On an Android device, you can put these programs to sleep. Specific instructions differ based on your phone’s manufacturer and the operating system, but on a Samsung device running Android 11, you can open Settings > Battery and device care.
Tap the Battery option and choose Background usage limits. The option Put unused apps to sleep should be turned on by default; if not, turn it on. You can also manually add misbehaving apps under Sleeping apps—those that only occasionally run in the background—and Deep sleeping apps—those that only run when you open them. Choose the category, tap the + icon, select the offending apps, and click Add to put them to sleep.
Your device may notify you when a specific app is using too many resources and prompt you to put the app to sleep or uninstall it. Don’t ignore these types of warnings.

Install Updates
Something else not to ignore? Updates. Phone manufacturers and app developers roll out software updates on a regular basis, and these security and feature upgrades protect phones from security flaws and help them run advanced apps.
On your iPhone, go to Settings > General > Software Update to manually check for OS updates. Tap Automatic Updates to install them automatically when the phone is on Wi-Fi and charging. For an Android device, look for a Software update or System update option in Settings.
You should also have your apps set to update automatically. Open Settings > App Store on an iPhone and make sure App Updates under the Automatic Downloads header is turned on. On Android, click your user profile in the Google Play store and choose Manage apps & device. If there are updates, an Updates available option will be visible.
Check for Malware
If your phone is still overheating, malware may be the culprit. The Loapi Android malware, for example, can max out your processor’s computing power, overheat the battery, and cause permanent damage to the device. If your device is running slower than normal, launching pop-ups, and getting hot even when idle, it’s possible your phone has a virus.
Apple’s walled garden approach to iOS apps means your iPhone is less likely to be hit by malware than an Android phone. If you’re regularly downloading new apps from the Play Store, make sure those downloads are being scanned. Open Google Play and click your user icon. Select Manage apps & device, and look for the words No harmful apps found. (You can also tap that entry and perform a manual scan to be sure.) Tap the settings gear on this page and make sure Play Protect is enabled.
While this is a nice tool to have, it won’t solve for every problem. Apps infected with harmful malware have found ways to circumvent the Play Store’s vetting process. When this happens, Google can disable the app, but those who download it will need to uninstall manually. This is what happened when 16 apps infected with Joker malware, and another 21 apps with HiddenAds malware, were discovered in the Play Store.
If you think your device has been infected by malware, or you want to prevent such an issue, many popular antivirus companies offer free antivirus apps for Android, or include them as part of a multi-device subscription. Bitdefender, Kaspersky, Norton, and McAfee are all PCMag Editors’ Choice picks in the category.

How to Stop Phone from Overheating
That the phone is getting hot might be harmful for it and its battery life. Many phone owners complain about overheating problem of their phones and want to figure out a way to solve it. Actually, there are several reasons such as the surrounding temperature of the phone, large storage taken up on your phone, apps running in the background and many more. To solve this problem, we provide some practical methods to help you cool down your phone.
Ways on How to Stop Phone from Overheating
1. Keep Your Phone in a Cool Place
You may easily find that your phone is more likely to overheat when the weather is hot. So if possible, find a cool place for your mobile. What’s more, when you charge the phone, the charging module will also generate some heat. Thus, do not put your phone around something hot or beside other running devices and remove the phone case while it’s charged.
But remember, placing your phone in somewhere cool doesn’t mean putting it into a refrigerator, because that will also cause damage to your phone. However, you can cool down your phone by putting it in front of a fan or air conditioner vent.
2. Manage Your Phone Storage
Too many files and applications stored on your phone might also lead to overheating problems. In that case, you need to check out what kind of files eat your phone storage. You can go to “Settings” to view storage and delete some unwanted data, but if you find it too complicated, try the products below.
For Android Devices – Use Apowersoft Phone Manager
Phone Manager app now is updated to version 3.0 for Android, which can help you mange phone files directly on the phone.
On your phone, open this app and tap menu icon. Click “Space analyser” to see how much space you have used and how much space you can use. It also analyses how data like music, photos, videos takes up your storage. Press each item to view details, you can select and delete some items. And go to “APPS” tab, uninstall apps that you seldom use.
Also, this application has a desktop version, so you can use it to manage your phone through PC, transfer data between smartphone and PC and back up files. Just click the button below to download.
For iDevices – AirMore FlashDisk
If your phone is an iPhone, you can try AirMore FlashDisk, as it could not only analyse your iPhone storage but also add storage to iPhone. To make it work, you need to download AirMore+ app on your iPhone and connect your network to this disk. Then the result of your storage analysis will be shown on your app interface. And you may transfer files to the disk. Moreover, if you need the files stored in the disk, you can transfer them to iPhone or PC freely.
3. Update Your Apps and Close Background Apps
The applications you use might have some bugs, so the developers of the Apps often update them to fix the problems, which will also help you stop phone from overheating and make your phone work more smoothly.
And multiple apps running in the background may easily increase the burden of CPU, thus, you should close them.
4. Let Your Phone Have a Rest
Constantly working may also cause phone to overheat. So, after you have a long phone call, watch videos and play games, let your phone have some rests.
5. Use Professional Apps
Here is another tip for Android owners. As numerous apps are designed to help Android users solve overheating problems, you can download one from Google Play. Take CPU Cooler Master as an example, it will scan CPU status for phone, tell you the current temperature of your phone and which apps heat up your smartphone. Also, you can tap the snowflake button to cool down your phone.
Conclusion
Besides the surrounding temperature, heavy load of storage, background apps, and long-time working of your phone, poor battery will also cause overheating. In that case, you’d better improve phone’s battery life to prevent your phone from heating up.

Why is my Android phone heating up?
The Avast Guide to Android Apps Part 3 explains what causes Android phones to get so hot and what you can do about it.
Why do phones get hot?
Unfortunately, there’s no single answer to this question. Sometimes phones get hot as the result of too many apps running in the background. A bad battery or other hardware problems cannot be ruled out. Other times, it’s because of a malware infection.
Here’s the thing: All phones can, and usually will, get a little hot from time to time. But it becomes a problem when your phone heats up to the point where you cannot even hold it, or it begins to exhibit odd behavior. There are a number of reasons why this could happen.
Identifying the culprit
There are some telltale signs you can use to determine why your phone is heating up.
First off, heating can be caused by faulty hardware, but it can also be triggered by software glitches. There are three main areas in a phone that generate heat: the battery, CPU, and screen.
When a phone gets hot, the battery is usually the first place to look. Even moreso if the heat is coming from the back of the phone. Modern lithium-ion batteries are extremely powerful, which is why they sometimes get hot. The heat causes the battery to vent its organic solvents which could actually ignite from too much heat or a spark. The infamous Samsung Galaxy S7 explosions were caused by faulty batteries (that’s why they recalled 2.5 million units ).
If the heat is coming from the front of the screen, however, it may be due to the phone’s CPU or GPU. Both of these components create heat as a byproduct of operation, so when the processor is in demand, the heat production increases accordingly.
Likewise, if you are noticing heat coming from the bottom of your phone, there is a very good chance there is an issue with the charging unit.
How hot is too hot?
Remember, all phones get hot. But how can you tell if your phone is experiencing a problem? All phones have a normal temperature range of 37-43 degrees Celsius, or 98.6-109.4 degrees Fahrenheit. Since we don’t (yet) have thermometers in our fingers, we have to use our best guess to judge when it might be a good time to stop binging on YouTube videos and let our phone catch its breath.
Why do phones get hot?
Let’s say you have a phone that is literally too hot to handle. Here are several more reasons why it might be happening:
You’re gaming… a lot!
Come on, don’t tell us you haven’t binged on Clash of Clans or one of the many Tetris knockoffs on your way to work or on a lazy Sunday. Much like PCs, gaming on a smartphone taxes the CPU and GPU to their limits, which causes them to generate a lot of heat. While the occasional gaming session won’t kill your phone, those spanning several hours are not recommended without frequent breaks.
Too many background apps
As you minimize your Gmail app to check out Facebook, you are not actually turning it off. Rather, your Gmail is still active in the background. Ditto that for every app you minimize. The more apps you have running in the background, the harder your system has to work to maintain them. Generally speaking, background apps aren’t typically a problem. However, if you never go into settings and turn them off, they could turn into one.
Binging on streaming videos
Yes, unfortunately, binging on YouTube or Netflix for season-long sessions is just as detrimental to your phone’s health as marathon gaming. Truth be told, anything that keeps your screen lit for long periods of time and uses your phone’s GPU will cause the device to heat up.
You have less-than-optimal settings
Turning the brightness way up, collecting all those widgets and 3D wallpapers, and using the sleep setting for a long session of audio or video are all rather taxing on a phone’s performance. If your phone is heating up, it might be a good idea to dial down the eye-candy and see if that helps. 
You left the phone in the sun
App and OS Issues
Certain bugs in apps can cause your phone to overheat or misbehave. Same goes for your phone’s OS. Because these apps have to run on different types of devices using different configurations and operating systems, they may act optimally on some, less so on others. The best way to stop them from malfunctioning is to keep them updated.
Cryptocurrencies like Bitcoin and Ethereum are also on the suspect list. While almost everyone’s heard of them, what few people know is that the sudden onslaught of cryptocurrencies has spawned a dark industry. Mining cryptocurrency takes a lot of processing power, and miners are often torn between the cost required to mine the coins and the market value of the coins themselves.
Cool your phone down
More often than not, the reason your phone heats up is due to a number of different issues, not just one. Here are some tips to help you drop the temperature.
First, never put the phone in the freezer. Suddenly introducing your phone to radically different temperature ranges can cause the screen to crack and the system to experience hardware issues. Similarly, putting a phone in the fridge will cause condensation both in and out of its shell, which can damage electronic components.
Better suggestions include:
Turn off that app
Remove the case
A skin or phone cover can act as insulation, causing a buildup of heat. Remove it to let the phone cool off. If the problem persists, use the phone without it.
Run the phone on low power
On Android, look for Battery Saver Mode.
Turn off unnecessary settings
Too often, people leave GPS, Bluetooth, or Wi-Fi options turned on, even when they don’t need them. Turning off unneeded apps can end overheating and save battery life. Better still, turn on Airplane Mode when you don’t plan on using your phone.
Get rid of junk
Trash not only the apps you don’t use, but also junk data that useful apps keep collecting as well. Avast Cleanup for Android can help you out here.
Turn the brightness down
Or turn on Adaptive brightness.
Keep your apps up to date
Updating is essentially another name for optimizing. The more optimized an app is, the fewer resources it uses, which translates to less of a likelihood that it will heat up your phone.
Change the charging cable
Every once in a while a faulty charging cable can cause the charging unit to malfunction. If the heat is mostly concentrated around the cable port, then you might consider switching to another cable.
How to prevent overheating in the first place
Start with an antivirus. This is your bouncer at the door, making sure nothing harmful gets in to heat up the place, including cryptojacking malware. A robust cybersecurity software like Avast Free Antivirus blocks the malware on the spot, as well as alerts you if a website you try to visit is infected. Take the step to protect yourself. and your hardware.
Also, keep in mind all of the above advice, especially the commandment not to leave your phone in direct sunlight. Depending on how strongly the sun is beating down, your phone could overheat very quickly say if you leave it on your dashboard in your car. Stay mindful of where you place it so it doesn’t get fried when you’re not looking. If we treat our phones with care, they’ll continue serving us well.
