Samsung Galaxy S5 becomes very hot - Tips!

In this article we want to give you advice and tips to when you find out, that your Samsung Galaxy S5 smartphone becomes very hot.

The generated heat at the Samsung Galaxy S5 usually comes from two hardware components:

     - processor (CPU)
     - battery

Most of the generated heat at both components is created at the same time, since a high CPU load always attracts a high battery consumption. Now, you will certainly ask: Why becomes my Samsung Galaxy S5 so hot?

At first: Cooling the CPU in a smartphone in general is very difficult. Since the processor has no active cooling, it can always be that it is running hot. For example: When a computationally intense game or application demands performance of the CPU. The compact design of a smartphone like the Samsung Galaxy S5, makes it hard for the hot air to escape outside. The heat is then delivered to the battery cover or on the display glass of the Samsung Galaxy S5. These parts are then sometimes very hot. If the cause is due to a game or an application, then that is no problem and your smartphone is working correctly.

But if the Samsung Galaxy S5 becomes hot in stand-by or when using the Android browser, then there is an error. This may be caused by a software problem or by hardware failure.

Possible software faults:

1. A New firmware has been installed on the Samsung Galaxy S5 and no factory reset was performed. Since a firmware update deletes not all data from the old system it may lead to computationally intensive overlap, which then lead to the heat development of the Samsung Galaxy S5 CPU. Solution: Carry out factory reset.


2. If a new firmware is available, necessarily install them. In general, system applications, the tug on the performance are optimized and therefore the smartphone becomes not so hot anymore.

3. Your Samsung Galaxy S5 can not go to deep sleep, because an app permanently demands performance from the CPU. Here you can check via the app Android Assisstant which apps requests constant processing power of the CPU. Navigate within the app on Tools -> Battery use

Possible hardware failure:

Defective battery. When the battery is defective, it may be that it issues an increased heat generation during charging and during consumption of power.

The above mentioned causes occur most when your Samsung Galaxy S5 becomes hot.
