Why hot Android phone?

Modern smartphones can heat up to too high temperatures. Why is this happening and is it possible to deal with it?

push-Button phones is never heated. Had no such problems and the first smartphones that were running the operating systems Symbian and Windows Mobile. Things changed only with the popularization of Android. With the development of this operating system began to experience increased demands on processor power. Also began to appear incomplete application, which adversely affect the performance of the device. And these are just a few of the causes of overheating of the smartphone or, in rare cases, the tablet.


Most often, the degree of heating of the device depends on the processor. As an example, let us remember the home computer. In his system unit is also a processor. But it is hidden under the massive cooler, as the chipset under load is strongly heated. The ARM architecture used in mobile processors, enabled to reduce power consumption, and simultaneously reduce the degree of heat. But sometimes the unit still seriously hot. Why?

The fact that not every processor is the perfect. Sometimes engineers admit some of the errors, which are detected only after the start of mass production of the chipset. Something similar happened with the Qualcomm Snapdragon 810. The product received huge computing power, but the processor under the slightest stress begins to heat up. Against the competition he was incredibly hot — this was particularly noticeable when shooting different devices the imager. From MediaTek from similar, but less noticeable problems suffer chips Helio X10, X20 and X25.


Nothing to do with processor installed, you can not. To worry about the smartphone is not worth it. With strong heating system reduces the clock speed of the chipset. This reduces performance, but saves the inside and the battery from damage.

The use of the smartphone when recharging

push-Button phones at the time could easily use the time when they are recharged. But modern smartphones are getting from a charger current with very high voltage. And if you are at this moment going to talk on the phone, then this will increase the heating processor. The result could be severe overheating. But in rare cases it leads to swelling of the battery and even fire.

Ни в коем случае не разговаривайте по телефону, когда тот заряжается — в конце концов, отсоединить его от charger труда не составляет. А вот открыть браузер и совершать прочие несложные действия вы вполне можете.

Defects structure

Is another problem that it is impossible to fight. It happens that the machine heats up due to the fact that the engineers messed with its innards. Remember Samsung Galaxy Note 7 — where the creators have not added space between the battery and walls of the housing, which cooling was very inefficient (also there was the problem of the controller not takes phablet in the resetting in the event of overheating). In the case of using the Snapdragon 810 and other processors requires installation of the thermal tubes operating in the manner of a passive cooler. Needless to say that some manufacturers refuse to this idea for the sake of saving?



Some people do not wish to part with their gadgets even on the beach. And then they are surprised that they have hot Android phone and drains the battery. If the body of the device to direct sunlight, the smartphone can not overheat. The hardest heats up plastic case. To solve this problem is very easy: do not get on the beach the smart phone from the bag. In the end, so you will not only relax the body but also the mind.

Poor quality of connection

Earlier devices Nokia very hot when using GPS or Wi-Fi. Now the wireless modules are more energy efficient, and the heat they emit nearly. But there is one exception. The mobile communication module depends on the coating quality and the operator's equipment.

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 unit will regularly go from 4G to 3G and back. If your city is a situation that you can travel time in transport to leave only a 3G connection — this will reduce heat and increase battery life. This is done as follows:

Step 1. Go to "Settings».

Step 2. Select "Connection».

Step 3. Click on the item "Mobile network».

Step 4. Select "network Mode».

Step 5. in the list, Select the desired option. Please note if your smartphone doesn't support LTE networks, in the list of available options will be only 2G and 3G.

Else device may get hot when downloading large amounts of data. For example, you can use a torrent client for Android to download a movie in high definition, which weighs about 7 GB at this point, the smartphone could be heated to a sufficiently high temperature. If it scares you — in the app settings you can set the limit of speed, then the load on the machine will be reduced.

Software activity

Virtually any processor under a certain load begins to heat up. Modern chipsets in many modes involve only two or four cores. This allows him almost no heat, at the same time it reduces power consumption, prolonging the battery life. But some applications have poor optimization — they load the chipset in full. Do this and almost all games with three-dimensional graphics.

If the games are clear, to identify power hungry applications much more difficult. You can see what programs consume the most battery power. But this does not mean that they heat the CPU, although the probability of coincidence will be quite high.

of the renowned programs, we recommend that you remove or at least disable Facebook. Client social network collect almost any information about user activity that adversely affects the performance of the device.

Physical defects smartphone

If you wondered "why the heated Android phone" only after a year of use, the reason for this is either some sort of installed app or a physical defect. If you regularly drop your device, then inclines to the second option. One of the drops could move the antenna, which leads to deterioration of signal reception smartphone every time you will try to improve its programming methods, thereby tensioning components. Or moisture could be oxidized contacts causing high 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 guts of the device, contact the service center. It will help you, if not for free.

  • The main cause of overheating of processor today is directly a sufficiently low frequency compared to the frequency Windows, and a high enough pixel density for this frequency. For comparison. Take the standard CPU on the Windows, two or four cores with a clock frequency of 3.2 ghrz and resolution 1280х720пикселей on the screen. Most likely processor to be heated to be no, but there are many factors influence, and cooling system and many other factors. Take smartphone with the same resolution, usually the frequency of these smartphones reaches a maximum of at best 2 ghrz. That is, the pixelation remained, and the resolution of the clock frequency was lowered. As a consequence, have the device at maximum frequency. That is, at the maximum. Of course, this is the main indicator of congestion — work at full capacity without a free resource with subsequent dispersal frequency. From high pixilation is followed by another without a doubt an important factor — the growing weight of digital data in connection with expansion of volume of the occupied space. Actually, I need it all, even the traffic could not rise itself, the main two characteristics of the file, if people download pictures and videos — Pixelate image if people download music and videos — bitrate. The solution to overheating looks very simple — a complete rollback of the increase of digital data in the direction of the source formats. Or else, search for files, having a light weight and having high quality. The main and constant format such files — the text. Next comes the image. And after is audio. At the moment on all subsequent, data file formats can fit and be played on virtually any modern device.
