My iPhone 5 is not quite 1 year old yet and I've been noticing that battery loss. Went into the apple store to have them check out my iphone and they said i'm almost at 400 charge cycles. At about 600, I can expect the battery drop into the red zone (I assume that means 50% or less capacity). I plan to sell/trade in my iphone 5 and get a 5s (most likely). There's the ebay/craigslist route where I can probably get $400-450 or the gazelle/nextworth route where I can get $315. While I would like to get top dollar for it, I don't feel quite right about selling it to someone on ebay, only to have it substantially lose charge after 6 months or so. Am I just crazy for thinking that way or should I not care?
