Almost all of us are using smart phones these days. Phones get heated on constant usage Most of us face the problem of our phones getting heated up. This problem occurs mostly in Android phones. But this kind of heating up is not good for the phone. It is also not good for those who are using it. For this, it is important to know the advice by experts, on what to do in this matter.
Why does the smart phone get heated up? Software and hardware are like two eyes. Both should work in coordination. If they are not coordinated, the processor in the phone will work overtime. This produces heat. If optimization between these two is good, there will not be such problems. Many smart phones have a more effective processor, and a high end hardware facility. This leads to heating up problem.
Most importantly, sophisticated smart phone processors like snapdragon 652, and snap dragon 810 have these kind of problems. The heating up of a smart phone depends on the amount of power that is being used up by it. If you are playing a game with a lot of graphics, there is a need for more energy from Central and graphics processing units. This leads to generation of heat. Excess heat, slows down the processor. Stop using the phone when it is very hot and use it again, when it cools down. For some functions, more battery power is necessary. During this time, it is normal for the phone to get heated up.
Will they burst?
Even cars and bikes become hot, when driven for a long time. The same is with mixers or grinders that are worked on for a long time. Use a laptop or TV for some time and later feel it with your hand. You will feel the heat. Heating up is not just for mobile phones. Malfunction of processor, battery, signals, environment, are all responsible for the heating up of a mobile phone. Except for some fault in the battery, there is no chance of mobile phone bursting, just because of heating.
Games damage processor
If you play games for a long time on the mobile phone, CPU is loaded. Due to games with heavy graphics, the phone has to multitask and if this is so for half-an-hour or so, you can notice that the phone is heated up. That is why do not choose games that take a long time to get over.
The slim design of the phone too leads to quick heating up, due to lack of surface area. The heat has no room to spread, leaving letting room for it expand.
When the battery is charging, negative electrons are stored. They turn to positive when the phone is in use again. Because both these things happen simultaneously, the electrons move very quickly, leading to heating up of the device.
When used in an area where the signals are weak, the mobile automatically searches for signals. This is not apparent. Signals could be either wifi or mobile signals. So when not using the net, switch these off.
Heat in the surroundings
When it is very hot in summer season, phones get heated up very quickly. Added to the atmospheric heat, is the heat produced in the phone.
In all phones?
Heating problem occurs in all smart phones, including iphone and Samsung. While using camera, games, opening four or five apps, and mobile data, the processor gets heated up. Because of the extra energy being used by the processor, the phone is heated up. When not using them, switch off all of them. The heat reduces within minutes. If the phone temperature is 40 degrees or more, even after switching off all these, then it is assumed that the phone is faulty. It is understood that the hardware, software optimisation is not done properly. Or it is a battery problem.
Forgetting to close apps
Normally, after using an app, we go back to the Home page by pressing back button. When apps are not closed after using, they keep working in the background. For this, the processor needs to work with extra energy. That is why heat is generated. That is why it is necessary to close the app after use.
In a laptop or a desktop computer, there are fans that dissipate the heat that is absorbed in the atmosphere. There is no such facility in the mobile. Therefore, the heat is felt when touched.
Update the software
It is always necessary to keep the software on the phone updated. In some phones, the software and hardware do not get optimised. That is why companies are changing the software and giving updated versions. If these are installed, the heat problem might be resolved. Software updates are found in 'About' option in phone settings.
Disable unnecessary items
Always keep the phone location button switched off. Switch it on whenever necessary and switch it off whenever the task is completed. If this button is switched on, the phone keeps constantly searching for Geographic Positioning System (GPS). As such the battery is worn out. Also the blue tooth option should be switched. If it is on, it will search for a nearby device, leading to heating problem.
App for cooling
An app called 'Greenify' is available. There are several options in this. After downloading the app, select settings. When you use an application and go to another application, the app will identify the previous one in the background and close it. Specially, apps like Whats App and Facebook, use up a lot of data and battery power. Greenify app will close them when they are in background. Battery life will improve. Load will decrease on the processor and there will be no heating up problem. There is another option, through which not all apps in the background, but only those you select will be closed. Supposing you check your mail frequently. If you do not want it to be closed, Greenify will not close it. All these have to be selected in the app settings.
App notifications too are load on the processor. Keep the frequency of the app notifications far apart. Or switch of the notifications. As such, even if apps are not open in the background and do not function, decreasing the load on the processor. But if you switch off the notifications, you will not have any information regarding the app.
The processor is loaded when apps are open. Even if they are closed, there is some pressure on the processor. Because these have to be maintained, actively. The phone gets loaded, if every app of your fancy is downloading. That is why the apps you use once in a way can be deleted.
Use of data
When 3G and 4G data is used constantly on the phone, the device is heated up. This is because of the constant functioning of the CPU. At least half-an-hour should be allowed in between.
When data is necessary in the smart phone, the network should be changed to 3G or 4G. It is better to select 2G for speaking. Because 2G signals are strong. The headache of searching for signals is reduced. The processor remains cool.
While charging the phone, keep it in a flat area. This releases the heat from inside. If the phone has a plastic cover, the heat is not dissipated.
Still heating up
If the phone is still getting heated up, despite all the precautions, it might be due to battery or lack of optimisation between hardware and software. Backup all the data on the phone and select factory reset in Settings. This will restore the original setting of the phone as when your bought it. All the data, apps and settings will be deleted. This also will reduce heat. If phone is heated up even after this, take it to the service centre and get it checked. You can ask for replacement. If the warranty is up and the problem persists, install custom RAM on the phone. If the heating up is due to operating software, the custom RAM will improve the situation.
Do not use when heating up
Optimisation might not be good, charging might be wrong, or it might be due to playing heavy games, browsing for long hours, watching videos, camera etc. When the phone is getting heated up quickly, stop using it. If you continue using it, the chip will be destroyed because of the heat. It is better to give some rest to the phone, if it is heating up often.
