Last Update Date : Apr 19. 2018

Factors < Outside condition and the design>


As Galaxy S4 has slim design and use high performance CPU, you may feel your device is hot to the touch while using.
But, this is normal and should not affect your device’s lifespan or performance.

1) All of mobile devices from Samsung have been observing the International Safety Specification(EN563).

2) while using the device under the environment that has high ambient temperature , you may feel the device gets hotter than usual because your device work in the thermal equilibrium status with an ambient temperature.
But it is commonly seen not just on Samsung devices, but many other manufacturers devices also ; when the device is used, and it is a general phenomenon of all electronic devices.

3) And while charging, the device may heat up. But, Samsung device observe the International Safety Specification(EN563).

 

2. Factor < End user usage condition >
Heating of smart phone depends very much on how you use the device.
Please refer below instruction ,this will help in improving the device heating .

1) When you closes the application using HOME key not back key, the application is still working and occupying RAM even it’s not being used. The temperature of your device is related with CPU usage which is affected by running applications.
Check the Task Manager and close unnecessary programs running in the background. Then, you can reduce the
consumption of battery and increase of device temperature.

 

2) Keeping Wi-Fi and Bluetooth, GPS “ ON “ is often the main cause of battery drain and high temperature of your device because it works periodically to search AP, a satellite, the equipment.
Turn off wireless functions when not in use. Then, you can reduce the consumption of battery and increase of device
temperature.

If you use the Quick panel menu to toggle Wi-Fi, Bluetooth and GPS on/off, you will set the function more conveniently.

 

 

3) Keeping Tethering or Portable Wi-Fi hotspot on is often the main cause of battery drain and temperature of your device
Turn off Tethering and portable hotspot function when not in use.
Then, you can reduce the consumption of battery & also this will reduce device temperature  

 

4) If you set the background color of your device to other color except white, you can reduce the consumption of
battery and increase of device temperature.

5) Some 3rd party applications which downloaded from Play Store may cause unwanted battery consumption and
increase of device temperature.
After you download and install the 3rd party , if you feel the device gets hotter and battery life is poor than before,
we suggest to remove the application for your device.

 

3. Factors < The specific function of Galaxy S4>
1) Galaxy S4 support dual camera of high performance( 13M rear camera + 2M front camera).
When the device uses dual camera at the same time, CPU processing becomes faster because two cameras work
simultaneously and compose the images and the device can generate the heat at that processing.
But Samsung observe the International Safety Specification(EN563), so it should not affect your device’s lifespan or
performance and usage.

 
2) Samsung provide the periodic S/W upgrade to optimize the software features in order to provide added value for
Galaxy S4 owners throughout the device’s whole lifespan.  
You can conveniently upgrade the improved S/W binary via Kies tool or FOTA for the better optimized device’s status.
