The metal clip on the battery is what clips the battery to the logic board, and you'll need to pop it up with a plastic pry tool. Simply stick the end of your pry tool underneath the clip and gently pull upwards until it unfastens from the logic board.
To remove the battery, use your pry tool to break the adhesive along the right side of the battery, rather than using the plastic pull tab, which can rip or bend the battery. Once the battery is free from the adhesive, you can pull the old battery out of the phone.
Here's a checklist of things to keep in mind when removing the battery:
- Remove the #00 screw holding the battery clip in place.
- Pry up the metal clip on the battery with a plastic tool.
- Break the adhesive along the right side of the battery with a pry tool.
- Do not lose the grounding clip, which grounds your cellular antenna.
Before installing a new battery, make sure the grounding clip is in place and aligned with the #00 screw hole for your battery. It should be lined up under your battery clip.
