HMD Fusion Battery Replacement

ID: 176181

Description: Use this guide to replace a dead or worn-out...

Steps:

1. Let your phone's battery drain below 25% before starting this repair. A charged lithium‑ion battery may catch fire if damaged.
2. Unplug all cables from your phone and completely power it down.

3. Firmly press a SIM eject tool, bit, or straightened paper clip into the SIM card tray hole on the left edge of your phone until the tray ejects.
4. Remove the SIM card tray.

5. Use a T3 Torx screwdriver to remove the sixteen 5.0 mm‑long screws securing the back cover.
6. Use your fingernails, or angled tweezers, to remove any stuck screws.
7. The screws are secured tightly in the back cover, so you might not be able to remove all of them. If you can't remove a few screws, don't worry! Move to the next step and follow the guide normally.

8. During the next four steps, the remaining back cover screws might fall out unexpectedly.
9. To avoid losing screws, you can place a tray, bowl, or Magnetic Project Mat under the phone while you work.

10. Flip your phone over so the screen is facing up.
11. Insert the tip of an opening pick between the back cover and frame at the SIM card tray cutout.

12. Slide the opening pick along the left edge to begin unclipping the back cover.

13. Continue sliding the pick around the perimeter of your phone until the back cover is fully unclipped.
14. The corners can be tricky to unclip and may take some force. If you're having trouble, try prying up with the pick.
15. Don't try to fully remove the cover yet, as it's still connected by a delicate cable.

16. Carefully flip your phone over so the back cover is facing up.
17. Lift the back cover off the frame and flip it over the left edge of your phone, laying the cover flat on your work surface.
18. Be very careful not to strain the back cover's delicate cable.
19. During reassembly, place the back cover onto the frame and firmly press around the perimeter to reengage all the clips.

20. Use a spudger to pry up and disconnect the battery press connector.

21. Use a spudger to pry up and disconnect the power button press connector.
22. Remove the back cover.

23. Be very careful not to bend, crease, or puncture the battery during the next few steps. A damaged battery can leak dangerous chemicals and catch fire.
24. Use your fingers to carefully peel the three plastic tabs from the right side of the battery.

25. With one hand, fold the two outer tabs out of the way of the battery and firmly hold them down to secure the frame.
26. If you're having trouble with the tabs, you can fold them under the phone and tape them to the screen.
27. With your free hand, grip the center pull tab and pull straight up to fully separate the battery adhesive.
28. Lay the battery over the left edge of your phone.

29. Use your fingers to peel the battery's plastic film from the frame.
30. Remove the battery and its film.

31. Use tweezers, or your fingers, to peel the three battery adhesive strips off the frame.

32. Align the new battery adhesive over the frame, making sure that the three adhesive strips overlap properly.

33. Peel off the clear liner from the new battery adhesive.
34. Align an edge of the adhesive with the textured surface on the frame and press it down flat.

35. Use the flat end of a spudger or your fingers to press the adhesive onto the frame.

36. Grip the middle pull tab on the larger blue liner and peel it off the adhesive.
37. You have to remove this liner first, as it sits on top of the other two liners.

38. Remove the two remaining liners to expose the adhesive.

39. While holding the battery over its recess, temporarily reconnect the battery connector.
40. Lay the battery into its recess.

41. Firmly press the battery into its recess to secure it with the adhesive.
