Considering the fact that the iPhone 8 costs almost 1k for just 64gb storage and the 7s being a 7 with wireless charging I am thinking of keeping my 7 Plus for another year. Compared to my iPhone 6 which had heavy slowdowns after a year of use,it's faring extremely well. Who else's doing the same?
Your 6 had heavy slowdowns? I'm still using a 6! Performance is still pretty good, but I plan to upgrade this year. I would probably keep a 7 if I had one.
