I did a reboot last night before charging to 50% before sleeping, the charged in the morning.hmm, obviously you have to add all your cards again in the re-pair process, I did get emails for all of mine telling me that my card has been enabled for Apple Pay ... good luck with the unpair/re-pair, it a p.i.t.a.
Off the charger at 10am and things are looking better than yesterday. Will see if I make it through the night, which I was with 7.0.1, before I unpair/pair
