Highly recommend making sure you are grounded before removing the battery. You will be handling areas that could cause damage if you accidentally create a static discharge.

You will notice a disclaimer on the battery that states that if you remove the battery you void the warranty. Make sure your warranty has expired before performing this repair.

Starting near the lower area of the phone, carefully press the battery towards the top of the phone and then lift up.

Lift the battery up and over the top of the phone to expose the battery cable and port.

Using tweezers and opening tool, flip the lock on the port and carefully pull out the cable.
