[AC Question]

Galaxy Note 4, was fast charging perfectly for 1.5 years. Since last week, it stopped recognizing all 3 of my fast chargers. Girlfriends S5 charges well on all of them. My phone IS charging (micro-usb doesn't appear loose) but overnight it charges only 70 percent, averaging 10 percent/hr. I've tried pushing usb in firmly, moving it, no change. It never stops charging, as it would if it were loose, whenever I move it around. It charges so slowly, that even when in 'power saving mode' with all applications closed aside from browsing online, it still manages to lose battery life unless phone is in sleep mode.

Reading your post and symptoms described, I would say it's time for a new battery.

That depends on how deeply he discharges it. It could also be one bad pin on the microUSB connector.
