Did I kill my phone/battery?
So I have an iPhone 6 Plus that I had to replace screen on (months ago) and it was working fine until about two days ago. It started doing this no signal/ no service mess but if I bent the top of the phone by signal came back. I opened my phone (which I've done confidently on many of my iPhones) I was looking for the antenna and disconnected the power cable to my sleep/wake button. I plugged it back in when I realized I never turned my phone off but it wouldn't work, so I unplugged the battery.
I plugged everything back on and now my phone won't turn back on. I tried plugging it up to the charger, a hard reset. Nothing. And there is a weird warm spot or the top of my phone near the camera
Is this a good question?
