Hello, I've been looking for a while to buy an iPhone 6s Plus and I have been debating on whether or not I want to buy it off Swappa used or the Apple store new. So many people have suggested buying it off Swappa, but I have my concerns on how long the phone will last compared to a new iPhone bought in the Apple store. A new iPhone will have a brand new battery and I'm scared that if I buy this iPhone off of Swappa, someone will sell me a phone that dies super fast or something. Would you... 1.) Buy a pre owned iPhone 6s Plus 64 GB from Swappa for around $500 or 2.) Buy a brand new iPhone 6s Plus 32 GB for about $700 after taxes Since it's an Iphone, does my concerns on the life of the phone even matter? Overall, I just want to get a good value for my money since I've been saving up for it for a while. Thanks for your suggestions!
