I have been getting 2 days out of my 6+ during the busy work week. With the larger battery capacity, and fewer charge cycles over the life of the phone, I'll probably go 3 years with this one and hop on the S cycle next. Unless it gets super slow, but my 5 was fine after 2+ years except for the lock button which was repaired for free with the replacement program. OR they make the 5.5" screen fit a shorter frame with the '7'. Other than that, I'll probably hold off.
