Hi folks. This morning I woke up 2 hours late for my work only to realize that my iPhone 6 is not turning on. I can't get to the apple logo, can't hard-restart it, can't get any response from charging nor plugging it in to my PC/iTunes. It worked fine when I watched a video before I went to bed last night, but something happened and it died on me. Model is iPhone 6 (A1586) and it's a 4 year old perfectly working device - no scratchs / damages , never really droppped , perfect mint condition. What happened? Is it possible that the battery died completely? I really hope it is because I NEED to save that phone.
