It was very simple to do. Sadly it seems the battery might not be what was wrong with my phone though. I did run into two problems while doing this. The second adhesive strip ripped before I could get it off. That took some trial and error and a little damage to the first battery to get it out. Second, when I was replacing the screws on the inside of the phone I lost one. I wish there had been extra of those ones included in the kit. But overall happy with my experience. I would suggest this to everyone.
