Why is the phone heating up?

A modern telephone is a complex technical device, sometimes in no way inferior to a conventional computer. Under the plastic or metal case hides a powerful processor that performs the most complex tasks. During its operation, thermal energy is inevitably released, so the phone inevitably heats up. And the more complex tasks the user sets in front of the phone, the more the device heats up.

In most cases, a phone that heats up during operation should not bother the owner. Device manufacturers taught physics and made sure that the inevitably released thermal energy could not damage the technical stuffing of the gadget. It is constant overheating that is dangerous – when the phone heats up to a temperature of 50-70 degrees, this happens often and no longer has a direct relationship with the use of the phone.

The weakest link is the battery. Lithium – one of its constituent parts – is a very active metal with a low melting point. For such batteries, the upper operating temperature is 60 degrees. It is detrimental to him to constantly stay in conditions where the temperature around is elevated. At first it will discharge faster, then it may stop working altogether. When storing the battery at a temperature of 50 degrees, the degradation of capacity, according to researchers, increases six times.

In second place is the display matrix, it can also fail, or some of its sections will be damaged.

The very same parts of the processor, motherboard are most often able to operate at a temperature of 70-85 degrees. A slight overheating due to work, long conversations cannot harm them, but if the phone heats up to such a temperature, this is already a reason to run to a service center.

Phone gets hot while talking

The smartphone has a transmitter, which is responsible for communication. When talking, it works continuously, so the device heats up. He has to constantly exchange data, both for reception and for transmission. And the longer the conversation lasts, the hotter the phone gets. If the connection is not very good, for example, you are in a country house or in a forest, it will need more power to “reach out” to the tower, which means that the phone will turn into a burning brick even faster.

What to do?

There is nothing to worry about especially much, however, it is worth remembering: an overheating phone increases radiation. When talking, you keep it next to your head – this can negatively affect your health. It is recommended to use a headset or reduce the talk time. After a long conversation, the phone should be allowed to “cool down” without using it for some time.

Phone gets hot while charging

The reason may be the use of the wrong charger: non-native, out of order. In this case, the phone may be supplied with more voltage than it needs, and some microcircuit will have to extinguish the excess, hence the heating occurs.

What to do?

Use a native adapter purchased in the salon to charge your smartphone. The cost savings is a possible battery replacement that may be required, and this is not too cheap. Try not to use the phone while charging, and even more so not to load heavy files at this moment, do not turn on games.

Phone gets hot due to background apps

The greatest excitement among phone owners is the situation when their gadget starts to warm up for no apparent reason. It seems that the phone is lying idle on the table, but nevertheless, the temperature of the device rises and after some time it is impossible to pick it up and not get burned. The thing is that a modern smartphone can live an active life without human intervention. For example, in a moving train, it will constantly check the network, and this is the continuous operation of the transmitter. At rest, the phone constantly connects to the network to check incoming messages in instant messengers, download weather widgets, updates. If you have a large number of applications running in the background, then the phone almost never rests.

What to do?

Use any program that allows you to clear the RAM of your smartphone. In most versions of Android, this can be done with the utilities available. However, third-party programs allow you to better find all running processes and stop unnecessary ones. And also get into the habit of “cleaning up” your smartphone more often: don’t leave 100 open tabs in your browser, close applications that you no longer use, and don’t just minimize them.

Phone gets hot when playing games

Also a standard situation, especially when it comes to complex games with good graphics. To run such applications, you need all the power of the processor, which works in full, which means it heats up more than usual. Too much overheating indicates that your device “does not pull” this or that application.

What to do?

If the smartphone is not powerful enough, do not try to run too heavy games on it. Take breaks from heavy use by turning off all apps completely and allowing your smartphone to cool down. If you are uploading heavy files, pause the process. You should not play in stuffy public transport or, for example, in the heat on the beach. A combination of several reasons can lead to overheating.

The phone heats up due to WI-FI, Bluetooth, 3G

If you have all data transfer technologies running all the time, as well as a GPS sensor, don’t be surprised if your phone is constantly overheating. Of course, these are not so big “degrees”, but all simultaneously running modules can collectively lead to overheating.

What to do?

Turn off the constant search for WI-FI, do not leave the navigation module on all the time, especially if you are not driving and driving on the navigator right now. When you use wireless internet, turn off your mobile internet. Also turn it off in a train or plane – when there is no network, the transmitter does not calm down for almost a minute, trying to “reach out” to the transmitting tower. And not only makes the phone warm, but also drains the battery.

Phone overheating due to software bugs

Poorly designed applications don’t use operating system resources well enough. As a result, they send the wrong commands to the technical part of the smartphone, which reacts incorrectly to them, and, trying to figure out the confusing instructions, the processor starts to work unnecessarily hard.

What to do?

Find out which program is causing the overheating and remove it. Update the programs installed on the gadget, as developers constantly “fix” errors. In general, try not to keep extra and unused programs in stock. This will save space and prevent your phone from getting hot.

Smartphone overheating when watching a movie

This is especially inconvenient if you have to hold the phone while viewing. Most often, a movie cannot cause a phone to overheat, the temperature increase that occurs will not harm the gadget, so there is no reason to worry.

What to do?

It is normal for the device to become warm during active use. If you are going to watch an hour-long movie, for example, on a plane or train, think about how to fix the gadget. It is best to make a stand on which it will be in an upright position. Take breaks. Turn off running modules, including mobile Internet, stop downloading heavy files.

The phone is heated in the sun, in your pocket

A modern person without a phone is nowhere. True, it is worth remembering that in some conditions it is still not recommended to use the technique. The cause of overheating of the phone can be the banal exposure to high temperatures. If you read a book on a smartphone on the beach, it will definitely heat up. If you put it in a cramped pocket and get stuck in a stuffy bus for an hour, get ready for dangerous heat. Especially if at this time, for example, the device is downloading a heavy movie, or actively checking instant messengers.

What to do?

Take a paper book with you to the beach. Do not leave your phone in direct sunlight. If you put your device in your bag at the beach or at a picnic, don’t leave it upstairs, better bury it deeper. Set the screen to auto-lock so that the camera, call, and other applications do not accidentally start in your pocket. It is better to hold the phone in your hands if you put heavy files on download.

Phone gets hot due to case

Yes, the wrong case can cause your phone to overheat. If you actively use the phone: play, talk for a long time, watch a long movie, it is better to remove the cover so that the case cools down faster. In general, a case that is too tight can be the cause of problems.

What to do?

Change the “clothes” of the phone. A good option is silicone cases. They leave enough space for cooling the gadget. Remove the case if you use your smartphone to its fullest.

Overheating due to operating system problems

Often the phone starts to warm up due to the garbage accumulated in the operating system. These are “hovsticks” of remote programs, a cache of running applications, copies of all the photos and videos that have ever been downloaded saved on the device. With such a background in the RAM, the device starts to boot longer, search for the necessary information longer, work more slowly and warm up more.

What to do?

First, look in the “Settings – About the system” section to see if your phone has been updated to the latest version of the available software. Sometimes just rebooting your phone is enough for instant cleaning, but if that doesn’t help, you can reset the settings to factory settings, thus removing all the accumulated garbage. Only first you need to save all important data by creating a copy of all contacts in the address book.

The phone heats up due to defective or broken parts

If you have followed all of the above tips, and the phone is still warming up, and in the most incomprehensible situations, it may be a matter of hardware. A factory defect or some burnt part may be to blame.

What to do?

If the problem has affected a new device, it can be returned under warranty. Otherwise, the device should be taken to a service center, where they will help you understand which part is out of order and tell you whether it can be replaced, or it will be cheaper to buy a new phone.
