Does anyone who own both watches notice any differences between the charging? My wife has the 38 and I have the 42. We are both on 1.0.1. When I wake up in the morning my 42mm Steel watch is cold and at 100%. Her 38mm Steel watch is warm and at 98%. I got mine May 8th. She got hers Tuesday May 19. On her Apple Watch app it says she has fully charged. I'm just nervous if something is wrong. I think however it might be a software issue. Anyone else experiencing warm watches when they wake up? ETC. Hope all is well.
