Wondering why the back of your iPhone is hot? Learn about the potential causes and tips to prevent overheating in this informative article.
Sometimes the heating of the iPhone is simply inevitable and you can’t do anything about it, no matter which technician picks up your device. Professionals from the iLab service center advise monitoring the overheating of the iPhone: if it occurs due to the launch of some application, try to use this application less; if the phone heats up during wireless charging, there is nothing to do here (this is normal); if the problem is systematic, pass complete device diagnostics.
Why is the Back of My iPhone Hot?
The most common reason for iPhone overheating (Back of My iPhone Hot) is the use of wireless charging . Because of this technology, the iPhone may well get warm, this is normal and there is nothing you can do about it. There is no need to worry about this problem, since the iPhone can independently regulate critical temperatures when charging wirelessly. However, if you use cheap charging or are not sure whether you got a high-quality charger, be careful and mix the use of wireless charging with charging using a cable.
Personally, I use wireless charging only when I need to charge my iPhone very quickly in the office or when I don’t want to look for my cable around the apartment. And I also advise you not to use wireless charging as the main type of charging your iPhone.
Potential Causes of iPhone Overheating
There are several factors that can contribute to your iPhone’s back becoming hot:
- Background Apps: Running multiple apps in the background can put a strain on your device’s processor, leading to increased heat generation.
- Software Updates: Sometimes, software updates can cause your iPhone to work harder, leading to increased heat production.
- External Factors: Using your iPhone in direct sunlight or in a hot environment can also cause it to become hot.
- Malfunctioning Battery: A faulty or aging battery can also lead to overheating issues.
2. Through video games
The second common reason why your iPhone might get too hot is when playing video games. If you’re an avid gamer, chances are you’ve burned your fingers more than once while playing PUBG or any other game on your iPhone. Especially if you play on older iPhone models.
Due to update
When updating software, your iPhone may become very hot. Apple mentions this in its instructions. There is nothing wrong with this phenomenon; there is no need to contact the service. Just wait until the new software is completely installed and do not do anything with your phone during installation, no matter how hot it gets.
4. The influence of the sun
You’ve probably heard that iPhones can turn off at very low temperatures. Oddly enough, above-zero temperatures also have a detrimental effect on the device and can cause it to break.
Therefore, we strongly advise against leaving your iPhone in direct sunlight and allowing it to overheat due to the sun. If you’re heading to the beach, make sure to keep your iPhone in a bag or shade to prevent it from overheating. If the device is already hot, try not to cool it suddenly and do not use the device. Wrap in a cool blanket (not damp) and wait until the iPhone’s temperature drops.
5. Downloading files from the Internet
On older iPhone models, the device may overheat if you download a large file. A TV series or a large Excel spreadsheet can cause the device to overheat. If you notice this with your device, unfortunately, there is nothing you can do about it.
Try to open and download large files on your iPad/MacBook so as not to overload your iPhone. You can also use AirDrop transfer to avoid the need to download files to your device.
6. Lack of memory
Don’t be surprised if the temperature suddenly jumps on a fully loaded iPhone. If there is insufficient memory, this is a completely normal behavior of the device system. If possible, try to clear your application cache so that your iPhone can continue to function normally.
Clean up sections of your iPhone or delete apps you haven’t used in a while. By going to the “Gallery” you can delete duplicate photos, videos and selfies to free up some space on your smartphone.
7. Moisture ingress
Due to moisture getting inside the iPhone, the contacts of the device may short out. As a result, the device may overheat. The critical condition of the iPhone in case of moisture ingress obliges you to contact the iLab service center as soon as possible for diagnostics, and then repair work/cleaning the device from moisture.
Please, in this case, you simply cannot ignore your iPhone overheating. This is a clear sign of damage. Therefore, contact the service center as soon as possible.
8. Damage to internal components
If your iPhone is severely damaged due to an impact or fall, the smartphone may overheat. This may be due to damage to internal components and failure of individual parts.
It’s difficult to say exactly what the cause of overheating is if your device was damaged by a fall. To do this, you will need to carry out a full diagnostic of your iPhone at a trusted iLab service center.
- Record 4K video
Few people know, but recording 4K video can cause your iPhone to get very hot. This is not so noticeable on newer iPhone 11 models, but on iPhone XS and below it is a real problem. Unfortunately, this cannot be fixed without losing video quality.
You can only reduce the quality of the recorded video if you go to Settings and then to the Camera app settings.
- Using low-quality chargers
One of the most common causes of iPhone overheating while charging is the use of low-quality chargers. In addition, because of this, the iPhone may not only overheat, but also fail. Therefore, try to only use MFI certified charging cables and power supplies .
Let’s summarize
iPhone overheating is a fairly common complaint among users. Basically, the device may overheat due to the use of power-hungry applications, lack of memory on the device, or wireless charging. you can prevent your device from overheating and ensure its optimal performance. Remember to take care of your iPhone and monitor its temperature regularly to prevent any potential damage.
