So this is my old iphone 5 64gb that i gave to my son a year ago, I had it replaced once with a refurbished a couple months after launch of the iphone 5, then again late year last even though it was out of warranty by about 4 months or so. After about 2-3 months with the 2nd refurb the phone started acting wierd, it would never show increasing/actual battery percentage while charging until you rebooted the phone, then freeze at that number until you rebooted it again. This didnt bug me majorly since it wasnt my phone anymore so i let it go on. At the same time the phone started constantly rebooting during any mildy intensive task. Then it stopped for a few months and has now started constantly rebooting again. Brought it to the apple store today and i was not expecting yet a 3rd replacement out of warranty, but i wanted to see if he could do anything. He said the logic board was most likely bad since everything else tested out fine but he kept getting kernel panics one after the other non stop. So.....the question is..replace it for $279? Or just sell it for whatever i can get? The phone still works great...when its working. Not sure what it would be worth. Maybe $300? At that price i could probably a 16gb 5s maybe.
