I successfully changed my battery today, but I was surprised that my new battery was completely discharged. I put it together and tried to turn it on. I got no response. I thought I had wrecked it. I headed to the Apple Store to buy a new phone. They were out of the 64 GB iPhone 6 for Verizon. When I left the store I continued to try to turn on the phone, and I got the dead battery indicator. I charged it up, and it has worked fine. Those tiny screws were very hard to work with. It took my 20 minutes to get it back together.
