I was having some trouble with my iPhone 6 about 2 and a half months ago, so I switched out back to my old iPhone 5. The 6 just stayed in a drawer since then, and obviously it was dead. I went to go charge it again to get something off of it. Left it plugged in for about 14 hours, and it still didn't turn on. Eventually I got the red battery to show, but the phone itself never turned on past that. Tried plugging it into my laptop and holding the power and home button to do a DFU restore but nothing happens. Any fix for this problem?
TIA
