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


                   Structure of various phones


                     1) PCB is much closer to customer's hands, hence heat can be easily felt.
                     2) PCB is
underneath the battery, hence heat is less likely to be felt by customer directly.

              - When products with HD LCD are used for a long duration, they
can get slightly hot.

              - LTE products
are normally equipped with 1.5GHz dual-core processor or above, and comprise of LTE modem that helps faster data processing. 
                As hardware performance improves, heat can also be generated due to faster CPU processing as a result. 

If products are used when connected to a charger, charging circuit can give up heat.
