when I use the included fast charging charger to charge my Note 5, the screen feels really warm after about 15 to 20 minutes. The fast charging uses higher voltage to deliver more juice and this causes the battery to heat up, right?
just to scientific about it, I used my infrared thermometer to check the temps. before plugging in the charger, the phone screen surface temperature was 78 degrees.(a couple of degrees above my room temperature) 15 minutes after I plug in the fast charger, the surface temperature has risen to 112 degree. after 30 minutes, it was 119 degrees and remained 119 until the battery reached 100%.
if I only use a regular 2A Samsung charger(like from my old S5 or Note 3), the screen doesn't feel warm at all. with the same thermometer, the screen surface temps ranged from 79 to 89. (so it does heat up, but not so much that it feels warm enough to my bare hands)
as with any thing electronic, heat is the biggest enemy. I'm wondering if using the fast charger all the time with the increase in temperature will shorten the battery's life expectancy? I usually trade my phones after a little over 1 year, so I guess it's not that big of a deal to me... but still...
