Hi, I just signed up for an account since I have been experiencing shut downs for a while now. I have an iPhone 6, 64GB from within 1st month of launch. I have been experiencing shut downs at various times. Sometimes I am using my camera, sometimes the phone is just sitting there. There seems to be no rhyme or reason to when. All times I have at least 45-50% of my battery charge left. Many times it's even more. I just had one this morning (what prompted me to look more online) that my phone came off the charger and into my pocket to go to work. I pull my phone out of my pocket and feel it vibrate real quick. When I look at screen, it is black, I push home button and nothing. After trying to get it to respond, I ended up plugging in and pressing home and power button for several seconds for it to finally turn on. When it came on, it had 93% battery. I have been into the genius bar in July '16 to address this issue and they didn't do anything. I tried my serial number in the apple program thing and I am not eligible.
