What to do if the iPhone gets hot, is there any kind of risk? — 2022

Surely on some occasion you have noticed that your iPhone mobile heats up. It is usually even normal considering the absence of fans and that sometimes there are more demanding processes, but is it normal if nothing is being done with the phone? Well, the truth is that no. If it happens to you with some regularity, you should review the reason, something that we will see extensively in this article to avoid major problems and also prevent excess temperatures from overheating the iPhone unnecessarily.

What are the risks of the iPhone getting hot?

Although in a next section we will tell you that there are situations in which it is normal to find the iPhone with a high temperature, the truth is that there are situations in which this is not normal. And even if it did, there are several dangers of a device like this being exposed to constant overheating. The main and most common are these:

  • It puts your own integrity at risk and, although the risk of explosion or fire is really low, the simple fact of handling it while it is hot can cause a slight burn or, at least, an annoyance.
  • Greater degradation of the battery, since precisely the internal heat is one of the factors that most alters this element, which, on the other hand, already tends to wear out over time.
  • Problems on the board that can lead to all kinds of electrical failures that prevent the correct use of the device or some of its functions.
  • There is a possibility that the device may not be able to turn on, either temporarily or forever.
  • The SIM card could be damaged by heat and, although melting is complicated, its chip could be defective.
  • Problems charging the device's battery, especially via wireless charging, but also via cable.

Actions that can change the temperature

In the following sections, we will tell you what the main causes of an iPhone, like other devices, can vary in temperature can be. Just as we analyzed occasions in which it should not be normal to notice that it is increasing.



When is it normal for it to get hot?

As we said at the beginning of this article, the heavy processes are the main culprits that the iPhone can get hot and that it is noticeable when we have it in our hand, even with a case. It also happens on a computer and that is that smartphones are ultimately a miniature computer. The most common situations in which heating is considered normal are the following:

  • If the iPhone is used in high temperature environments.
  • When setting up iPhone for the first time.
  • When uploading a backup from iCloud or iTunes.

  • At the time of transferring files to other computers.
  • When performing heavy processes such as photo or video editing.
  • When using the camera for a long time, whether photo or video.
  • In a video call that lasts for several minutes.
  • During the consumption of streaming video for a long time.
  • If the device is being used while charging its battery, either by cable or on a charging base.
  • If the device is charging with a non-MFi (Made For iPhone) charger or charging cradle.

Situations considered atypical for it to happen

Contrary to what was mentioned in the previous section, we find that the rest of the actions carried out should not justify the increase in temperature. Based on what has been reported by iPhone users for years, there are a number of actions that are normally carried out on the device and that can cause the temperature to rise unreasonably, so if this happens to you, you should be concerned:

  • Consumption of social networks.
  • Web browsing.
  • Consume video content in qualities other than 4K.
  • Normal phone calls via voice coverage.
  • Video calls with only two participants (FaceTime, Skype, Zoom...).
  • With the iPhone in sleep while charging via cable or an MFi charging base.
  • Putting the device to sleep while it is on the table or in your pocket.

Prevent iPhone over-temperature

If you have already had problems of this type or it has not been the case directly, but you want to prevent them, we advise you to read carefully the following advice that we will give you. This will make your iPhone less likely to heat up and therefore suffer some kind of deterioration and even save your own physical integrity.

The device already has a protection system

First of all, it should be noted that no fire hazard nor anything similar with your phone, since Apple implements a security system in iPhones that is capable of detecting high temperatures. In order to preserve both the integrity of the phone and your own, the device can go into stand-by automatically. You will detect it thanks to a message that appears on the screen informing you precisely of this, that the iPhone is in high temperatures and you must wait a few minutes to be able to use it.

iPhone temperature warning

The time that the terminal is in this state will depend largely on the conditions in which it is found. It will take longer if it is still exposed to inappropriate temperatures or you place it on a surface in direct sunlight, put it on charge or try to turn it on. That is why we recommend that, at this point, you apply one of the prevention systems that we discuss in the following sections, as they will help the message to disappear soon as a result of having already regulated the internal temperature.

Take off the case, charger and other accessories

Whether or not it is an official Apple case, it is recommended that to help the iPhone cool down you remove its protective case or casing. It is not for its safety, since it will hardly suffer problems due to the heating of the phone. It is really done to help the device not have elements that prevent it from cooling down more quickly. The same happens if you have the device charging, either on a charging base or through a cable. Even if these chargers are official, it is advisable that they be removed from the device as soon as possible.

Don't worry if your iPhone is out of battery and you want to recharge it. In fact, it is even positive that it does not have a battery so that it can be turned off and the temperature is regulated earlier. Once the device's warning message disappears and it has already been regulated, you can put it on charge and turn it on with total comfort. You can also put the cover back on it, but make sure it is not exposed again in bad conditions.

Keep it at a recommended temperature

Apple recommends always using devices like the iPhone in controlled environments that are free of excessive humidity and very high or low temperatures. The exact specification is that it be between -20 and 45º C, although by common sense we understand that these are very extreme limits and that the lowest temperature can be just as bad as the highest.

This may seem very obvious to you, but do not put the iPhone in the fridge , do not put ice, or any excessively cold element on top. It may seem crazy, but you have probably read or heard this as a recommendation and it really is the most absurd. The temperature contrast could be decisive in causing irreversible failures in the iPhone, as well as the risk that moisture seeps into the interior of the device and you will already know that water and electronics are not exactly allies.

What you can do is put the iPhone on a surface that is at room temperature and whose materials are more or less cold. For example a marble table or similar materials, as well as the floor. Of course, in the latter case you must be careful that no one steps on it and if you also have pets it is almost better that you forget the idea.

Turn off the phone for several minutes

Depending on whether the phone is more or less hot, you can keep it off for more or less seconds. Doing this will not only kill any processes that are temporarily heating up the iPhone, but will also kill those that are running in the background. Many times invisible tasks are being carried out internally in our phones and we are not aware of it and some can cause errors or failures such as excessive overheating. Therefore this turning it off for a few minutes is always a good idea to correct them once it is turned on again.

If the iPhone constantly heats up

The recommendations discussed so far focus on specific problems with the iPhone, but if the iPhone overheats on a regular basis, it is likely that none of these recommendations will work. This is where we find several solutions that we recommend you follow in the order in which you will read them, since if one does not work it will take you directly to the other.

Restore iPhone from backup

No one likes to lose their data and settings, so formatting iPhone and then uploading a backup of these data can be important. To do this, yes, we recommend you do a complete restore for which you will need to have a Mac or Windows PC to connect the iPhone to via cable.

That yes, the backup that you make previously can be both the one that is made through iCloud from the iPhone itself and the one that is saved on the computer. If you do it the first way, you will not need to connect the device to the computer, but if you do it through the computer, you will have to keep it connected so that it restores all your data.

Factory Reset

If the above way of restoring iPhone did not help you to get rid of the heating problem, it is possible that the fault that causes this problem is among the data stored in the backup. Therefore, now you will have to follow the same restoration steps using a computer, but with the difference that in the phone configuration you will have to choose the option to configure as a new iPhone.

Of course, some data such as your photos, calendars, notes and others will still be present if you synced them with iCloud and later sign in with the same Apple ID (you can see it in Settings > your name > iCloud). These will always be present on all your devices where you have logged in with the same account, so in the end they are always independent of backup copies.

Go to the technical service

If after all this you have not managed to solve your problems, unfortunately it will be because the device has hardware problems. The recommendation in this case is to go to an Apple Store or Authorized Technical Service (SAT) where they can accurately verify the origin of the problem and propose a solution. The reason for going to an official place is that they have more precise knowledge and tools to make the diagnosis.

If the iPhone is also under warranty and it is detected that it is a factory defect or any other reason other than misuse on your part, the repair will be free. In any other case, you will be offered a repair estimate in advance, which, of course, you will not be obliged to accept, although if you want to repair the device you will have no other choice.
