To answer your questions:
ABOUT NOTE 2
1) The applications that I use frequently are WhatsApp, Yahoo Mail and some video on YouTube for 5 or 10 minutes, depending on the link that I have been sent by the previous media.
2) The teminal had a use of 2 years, like the original battery. The new battery was purchased in a Samsung store had 6 months of use. (Although I clarify that the problem of overheating occurred from day 1 of use, fresh out of its original packaging)
EVERYTHING THIS WAS SOLVED WITH A NOTE 4. I HAVE IT SINCE 9 MONTHS AGO (EQUIPMENT WITH OTHER 6 MONTHS OF USE), AND I HAVE HAD NO DISADVANTAGES WITH THE OVERHEATING OF THE BATTERY, THAT FOR CERTAIN LASTS LASTS IN THE NOTE 2.
Thanks for your answer.
