DO NOT DO THIS STEP. It is totally unnecessary to remove the connectors, and they are a really big pain to put back in, and there is risk of damaging them, and it adds a lot of time to the process of replacing the battery. Just securely prop up the front panel, and then if you gently heat the back of the phone when removing the adhesive strips, the battery comes off easily. I could have saved myself about 2 hours and a lot of frustration if I had just left these connectors in. I wish the instructions here would just include this step (connector removal) ONLY IF the battery doesn't come out easily.
