Why is my smart phone hot and how can I minimize it?




- Heat from smart phones are generally from CPU in main board and chip.

  It can also occur more frequently for high-performance dual core or quad-core, that use 4G network.  

- Structure : PCB (Printed Circuit Board) locations vary by product design, and heat experienced by customers also can differ.


                   Structure of various phones


                     1) PCB is exposed to hands, heat is easily detected >
                     2) PCB is
underneath the battery, heat cannot be easily detected >


- When products with HD LCD are used for a long time, they can get slightly hot. 
- LTE products
are equipped with 1.5GHz dual-core processor and LTE modem that helps faster data processing. 
  As hardware performance is improved, heat can be generated due to CPU processing. 
If products are used when connected to a charger, charging circuit can give up heat.



 How to fix   

- When the smart phone gets extremely hot, stop use and leave to cool down.

  (Close all running programs such as games and apps)


- Have brightness less than 40% for indoors or engage illumination sensor to reduce heat from LCD. 

Do not directly connect the charger to the phone and remove battery for charging.

   Use a certified charger.
