Hi @Vasanth77, I'm sorry to hear about this.
I just tested this on a Xperia Z5 Compact with the latest software installed and the phone did not stop to charge when a call came in to the phone.
Does the phone stop to charge when you answer the call or just when it starts to ring in your phone? If you place a call while the phone is charging does the charging stop?
Are you charging your phone using a wall socket or a USB port? If you are using a wall socket, could you please try and see if the same thing happens using a USB port or the other way around.
I would recommend that you reboot your phone in safe mode. Does the phone stop to charge when rebooted in safe mode?
Let me know how it went! 
THE CHARGING DOES NOT NOT STOP COMPLETELY .
THE CHARGING SYMBOL IS THERE. BUT THE CHARGING TAKES LIKE MORE THAN 5 HOURS TO COMPLETE IF ANY CALL COMES INBETWEEN THE CHARGE.
IT CHARGES AT THE RATE OF 1 % FOR 10 MINS.
TO BRING IT BACK TO NORMAL.
I NEED TO PLUG OUT AND IN AGAIN . OR DISCONNECT THE CHARGER FROM WALL MOUNT AND CONNECT AGAIN .
Thanks for the update. 
Was there any difference when the phone was rebooted in safe mode?
I would recommend that you try with another original charger and/or cable if you have the possibility to do that.
Please keep me updated!
