Introduction

  1. KtKHZFEGNSqTtlRr

    • Remove the back cover of the phone.

    • The battery will now be visible.

    Pry off the back and separate it from the front of the phone case. You should see the battery once you pry the back off.

    (rewriting the second sentence)

    You will see the battery once the cover is removed.

    • Pinch the battery at the grey semi-circles on the top left and top right corners of the battery using your fingers and remove it from the device.

    On both sides of the battery, there is a lighter grey half-circle. This is the best place to use your fingers to gently lift the battery free of the housing. Set aside the old battery, then replace it with the new battery. It should easily fit into place.

    (deleted "it sits in") from second sentence

    Replace backing of phone, pressing gently to secure to back of phone case ( There seems to be a bit of repetition in this sentence so I rewrote it.)

    Reattach the back cover by pressing gently until cover is secure.

    • Remove the lower rear cover, using a small iFixit opening tool.

  4. eSMncFgGH1AxRHXh

    • Remove the six screws from the mid-frame of the device, using the T6 Torx Screwdriver.

    • Set the screws aside once they've been removed.

    Should say something like ‘Beginning from the middle of the device begin removing screws with a screwdriver…’ or ‘Using a screw driver, begin removing screws from the middle of the device…’ instead

    • Gently pull back the plastic tabs that secure the motherboard to the case.

    • Slowly pull the tabs, working your way around the case, until they are lifted and the motherboard is free.

    • Remove the motherboard.

    • The keypad and navigation ball may become loose and fall off the motherboard.

    First bullet should be red
