Everytime I would disconnect my phone it would die. Then when I did get it to turn on it would say to plug it into iTunes but wouldn't let me. Once you unplugged it from wall it would shut off.
Repair went really good I followed a video of a man replacing the battery the girl went to fast. Battery and phone works good seems like this battery dies allot faster then the original.
Real easy todo just take your time and go slow.
