My iPhone 6 plus had a black screen the other day after being on the charger all day. I did all the troubleshooting that they said to do online. No luck. Made an appointment at the Apple Store, to come to the conclusion that it was "DOA" as they called it. They said that there wasn't enough energy from the cord to the battery. They wanted me to buy a new phone. I went in ATT today to use an upgrade so that I was able to have my phone back. I was explaining to the girl what was wrong with the phone. She suggested that Apple may be wrong and go to batteries plus to see if changing the battery would help. I got the new phone, but I was going to revive the other phone. I was just wondering if anyone else had an experience like this with this phone. I was wondering if I should try to give it a shot.
