Button phones never got hot. The first smartphones running the Symbian and Windows Mobile operating systems did not have such problems. Everything has changed only with the popularization of Android. With the development of this operating system, increased requirements for processor power began to arise. Unfinished applications also began to appear that adversely affect the performance of the device. And these are just a few of the reasons that cause a smartphone or, in rare cases, a tablet to overheat.

Most often, the degree of heating of the device depends on the processor. As an example, let's recall a home computer. In its system unit is also a processor. But it is hidden under a massive cooler, since the chipset is very hot under load. The architecture of ARM, used in mobile processors , allowed to reduce power consumption, and at the same time to reduce the degree of heating. But sometimes the device is still seriously heated. Why?
The fact is that not every processor is ideal. Sometimes engineers make some mistakes that are detected only after the mass production of the chipset has started. Something similar happened with the Qualcomm Snapdragon 810. The product received tremendous processing power, but at the same time, the processor started to get very hot under a little more serious load. Compared to competitors, it was incredibly hot - this was especially noticeable when shooting various devices with a thermal imager. MediaTek suffers from a similar, but less noticeable problem, Helio X10, X20 and X25 chips.
You can not do anything with the installed processor. To worry about a smartphone is also not worth it. With strong heating, the system reduces the clock speed of the chipset. This reduces performance, but it saves the insides and the battery from damage.
Using your smartphone while charging
Button phones at one time could be safely used at the moment when they are recharging. But modern smartphones receive very high voltage current from the charger . And if at this moment you are talking on a smartphone, then a heating processor will be added to this. As a result, serious overheating can occur. And in rare cases, this leads to bloating of the battery and even its ignition.
In no case do not talk on the phone when it is charging - in the end, disconnecting it from the charger is not difficult. But you can very well open a browser and perform other simple actions.
Another problem that is impossible to fight. It happens that the device heats up due to the fact that engineers have made up their minds with its insides. Remember Samsung Galaxy Note 7 - there the creators did not add space between the battery and the walls of the case, which caused cooling to be extremely inefficient (there was also a problem controller that did not take the phablet to reboot when overheating occurred). In the case of using Snapdragon 810 and some other processors, the installation of heat pipes working in the manner of a passive cooler is required. Needless to say, some manufacturers abandon this idea for the sake of economy?
Some people do not want to part with their gadget even on the beach. And then they are surprised that their Android phone is warming up and the battery is running out. If direct sunlight is incident on the device’s body, then the smartphone cannot but overheat. The plastic case heats up most of all. This problem can be solved very easily: do not get your smartphone out of the bag on the beach. In the end, not only the body, but also the mind will rest in your place.
Bad call quality
Previously, Nokia devices got very hot when using GPS or Wi-Fi. Now wireless modules are more energy efficient, and therefore they practically do not emit heat. But there is one exception. The mobile communication module itself depends on the quality of coverage and the equipment used by the operator.
If you are in a car, bus or other form of public transport, the smartphone will regularly switch from one tower to another. With poor coverage, the device will regularly switch from 4G to 3G and vice versa. If this is the situation in your city, then you can leave only a 3G connection for transport while traveling - this will reduce heat and increase battery life. This is done as follows:
Step 1. Go to " Settings ".
Step 2. Select “ Connections ”.
Step 3. Click on " Mobile Networks ."
Step 4. Select “ Network Mode ”.
Step 5. Select the option you need from the list. Please note that if your smartphone does not support LTE networks, then only 2G and 3G will appear in the list of available options.
Another device may become hot when downloading large amounts of data. For example, you can download a high-resolution movie that weighs about 7 GB through a torrent client for Android - at this moment the smartphone can warm up to a fairly high temperature. If this scares you - in the application settings you can set a speed limit, then the load on the device will decrease.
High software activity
Almost any processor starts to heat up under a certain load. Modern chipsets in many operating modes involve only two or four cores. This allows it to practically not heat up, at the same time it reduces power consumption, prolonging the battery life. But some applications have poor optimization - they load the chipset in full. Almost all games with three-dimensional graphics do this.
If everything is clear with games, then identifying voracious applications is much more difficult. You can see which of the programs consume the most battery power. But this does not mean that they heat up the processor, although the probability of coincidence will be quite high.
We recommend that you remove or at least disable Facebook from known programs. The client of this social network collects almost any information about user activity, which adversely affects the performance of the device.
Physical defects of a smartphone
If you asked yourself the question “why is the phone warming up on Android” only after six months or a year of using it, then this is due to either some installed application or a physical defect. If you regularly drop your device, then lean towards the second option. As a result of one of the falls, the antenna could recede, which leads to a deterioration in signal reception - each time the smartphone will try to improve it with software methods, thereby straining the components. Or, contacts could be oxidized from moisture, thereby causing increased resistance - the energy in this place will go into heat, raising the temperature of the battery.
If you think that the problem lies in the insides of the device, then contact the service center. They will help you, albeit not for free.
