I am replacing a 2011 IPhone 4s 16 gig (Verizon) and am wondering what I should do. My 4S is shutting off anytime I am taking photos when I have plenty of battery life left, it has done it at 72%, 41%, and 27%, and as soon as I plug it back in it starts working again. I have not upgraded to iOS 8. I like the physical size of the 5s and I like that it has 32 gigs of storage available. I also really like the price. Since I tend to keep my phones forever I am wondering if it will be a bad investment to buy a year old 5s? I also think I might like the larger 6 physical size, but I am not sure what storage size I should get, 16 or 64 gig. I have a hard time paying $366 (including tax) for the 64 gig phone, but then I have heard from others that the 16 gig isn't enough space as the operating system takes up close to 8 or 9 gigs of space, but then someone else told me it takes up less than 5 gigs of space. I plan to store mainly music (about a 1000 songs), some photos (although I upload and delete frequently), and some apps (I have 62 on my 4S, but could pair that down if I needed to, esp. the games for kids which I can put only on my iPad). what would you do or what did you do when replacing your 4S?
