Step-by-step

1. 1

   Remove the SIM tray

   1 min

   Insert a SIM eject tool into the hole next to the SIM tray. Push firmly to pop the tray out and set it aside.

2. 2

   Heat the rear cover

   3 min

   Apply a heat gun or iOpener around the perimeter of the back cover for 2 to 3 minutes. This softens the adhesive holding the plastic rear panel.

3. 3

   Apply suction cup

   2 min

   Press a suction cup onto the lower half of the back cover. Pull gently on the suction ring to create a small gap near the bottom edge.

4. 4

   Insert an opening pick

   1 min

   Slide a plastic opening pick into the seam opened by the suction cup. Do not insert it deeper than 3 millimeters to avoid damaging internal components.

5. 5

   Slice the perimeter adhesive

   4 min

   Slide the pick carefully around the lower, left, and top edges of the cover. Keep heating the edges if the adhesive becomes difficult to cut.

6. 6

   Slice the right edge adhesive

   2 min

   Move the pick along the right edge near the power button with extra caution. Stop near the center edge to avoid tearing the fingerprint sensor cable.

7. 7

   Gently lift the back cover

   1 min

   Slightly lift the back cover from the left side, opening it like a book. Keep the fingerprint sensor flex cable connected for now.

8. 8

   Unscrew the motherboard shield

   3 min

   Use a Phillips #00 screwdriver to remove the 11 screws securing the plastic motherboard bracket.

9. 9

   Remove the motherboard shield

   2 min

   Pry up the edges of the upper motherboard cover using a plastic spudger. Lift the cover off and set it aside.

10. 10

    Disconnect the battery cable

    1 min

    Use the flat edge of a plastic spudger to pop the battery connector straight up off the motherboard socket.

11. 11

    Disconnect the fingerprint sensor

    2 min

    Pry up the fingerprint reader ribbon cable connector from the motherboard. You can now completely detach and remove the back cover.

12. 12

    Disconnect the display interconnect cable

    1 min

    Unplug the main interconnect flex cable running over the bottom portion of the battery to clear the removal path.

13. 13

    Apply battery adhesive remover

    2 min

    Apply a few drops of high-purity isopropyl alcohol around the edges of the battery. Allow it to sit for 1 minute to break down the adhesive beneath.

14. 14

    Pull the adhesive pull-tab

    2 min

    Locate the pull-tab labeled on the side of the battery. Pull the tab steady and straight upward at a low angle until the battery loosens.

15. 15

    Pry out the old battery

    2 min

    Insert a flat plastic opening tool under the battery from the side opposite the motherboard. Slowly lift to pop the battery out of the frame.

16. 16

    Clean the battery well

    2 min

    Scrape away remaining glue from the housing using a plastic tool and a lint-free wipe dampened with isopropyl alcohol.

17. 17

    Install replacement adhesive

    2 min

    Peel the backing off new double-sided battery adhesive strips and lay them flat inside the battery frame.

18. 18

    Set the new battery in place

    1 min

    Align the new battery with the housing and press down firmly across its surface to secure it to the adhesive.

19. 19

    Reconnect the interconnect cable

    1 min

    Snap the main interconnect flex cable back onto its motherboard press connector.

20. 20

    Reconnect the battery cable

    1 min

    Align and press the battery connector straight down into its socket until it clicks into position.

21. 21

    Reconnect the fingerprint cable

    2 min

    Hold the back cover near the phone and press the fingerprint sensor flex cable onto the motherboard terminal.

22. 22

    Reinstall the motherboard shield

    3 min

    Place the upper motherboard shield back into alignment. Secure all 11 Phillips #00 screws firmly.

23. 23
