Why does my samsung galaxy s4 say 'Charging Paused,Battery Temp too High'? Ok so i have already brought a new battery and done a factory reset and tried different chargers and still says it is over heating . Please anyone got any ideas or solutions?
There might be a fault with the battery temperature sensor, due to which it detects high temperature every time the battery temp rises a bit over the normal  (which is common when you use the phone too much or you're charging it).

Does the phone feel very hot when this is shown?  If not, then the sensor has to be replaced,  and take your phone to an authorized service centre.
