Last week I had my iPhone replaced at the apple store because of a problem with the vibrator motor. I used my 1 year warranty which was about to expire the next day. Then my replaced phone had a problem with the home key and I had to replace that. Now my im having problems with my third iphone. The last 2 days it has not charged past 90%. I set up an appointment today to fix it but today it happens to charge to 100%. WTF? What do I do? And on top of that when I entered this phone's serial # online and it says this phone's warranty expires. Isnt it supposed to be extended 90 days since I replaced a previous phone? They gave me a receipt for the 1st repair so maybe I can use that as proof that It should be still under warranty. Anyone know what I should do? Any apple geniuses on here? I got 2 issues sorry.
