The battery was draining fast and wouldn't last me half a day. It overheated multiple times to the point were I had to put it in front of my car ac fan
I had some trouble getting back glass off but with patience and a lot of heat I eventually got it without breaking the glass
When putting the battery in make sure you put it as far up as you can in the phone because the battery power connector is a little shorter than factory. Overall my advice is to TAKE YOUR TIME!! It took me 2 hours to do this job but in the end it was worth it. Clean the phone well while you have it open and make sure the connectors are all secure with a quick look over.
