Ok I will try the software reset with the program you mentioned, also in the meaning time i have done more testing, here the results:
ALL test were done on idle screen on and app open.
1.- Probe the humans - Game
on pause while playing level
starting at 27% battery
finished at 27% after 15 min
2.- Chrome - App
no use, white page idle
starting at 27%
finished at 29% after 15 min
3.- Dead trigger - Game
Pause menu while playing level
starting at 29%
finished at 27% after 15 min
4.- MX Player - App
playing normal video (NO HD)
started at 27%
finished at 29 $ after 15 min
After those tests i can say that the heat wasnt excesive on any test (but no use was done on any also)
It clearly looks like something is wrong either with my individual phone or with the model in general due to a very slow charge while using the device or even worst, loosing charge while being charged. I seriously doubt reseting software will do a change but i will try it before calling this thread done and going to the center you posted.
Thanks for your help, i was siriously hoping a better answer different than just go to tech support or dont use your phone. I thought a problem like this should have been addressed as the testing of the device was done in your labs. Or if it wasnt test and found on customer then a plan of action should have been taken like replace defective devices, this is a big stain for what looked like a good device. If it is just mine it is acceptable as long as the problem is solved, if not the only one ..... well someone need to be fired for letting go such a big issue in a premium phone along with compensation for the people affected.
I wont call this issue resolved until it really solves.
EDIT:
Test was with WiFi On and screen brightness at 40%
