First off, I know battery can be replaced free of charge. What I find ironic is that I didn't start to have issues with it dying at a certain percentage UNTIL literally the day they announce the issue, since then with testing it out seems to differ from each charge. I have a 5 16gb. Had it since release. I am OCD when it comes to my phone, I let no one touch it. Naturally I freaked out when it died in the 20% range the day they announce an issue. It has died a few more times since then, last week at 17%. Today at 21%, but here is the kicker. I tested it with very little usage, I am short 14 hours of a full week and it just got down to 21% so the battery is draining fine, it just shuts off within the 20% range. Does it need just to be "calibrated," or something else? All the horror stories I read is that it died more frequently than this one has so I have that going for it. I want the 6, I just don't have the money for it. ATT will buy it back for $200 but I have until 10/20 and I don't know if I would have a phone by then. I need to stop obsessing over this, I literally have a piece of paper with stuff written down on it. What do you think? I know someone who says their 4s regularly dies within 17-20%. What should I do? Like I said, I just hate people touching my phone and I know they have to open it up to replace the battery, I wonder if ATT will know to look for battery issues when buying it back because this thing is pristine and everything internal checks out just this aspect.
