Introduction

Use this guide to replace a dead or worn-out battery in your HMD Fusion phone.

Your phone's lithium-ion battery has a limited lifespan. If your phone dies quickly and doesn't hold a charge, it may be time to replace the battery.

If your battery is swollen, take appropriate precautions.

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

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.
Remove the SIM card tray.

Use a T3 Torx screwdriver to remove the sixteen 5.0 mm‑long screws securing the back cover.
Use your fingernails, or angled tweezers, to remove any stuck screws.
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.

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

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

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

Carefully flip your phone over so the back cover is facing up.
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.
Be very careful not to strain the back cover's delicate cable.
During reassembly, place the back cover onto the frame and firmly press around the perimeter to reengage all the clips.

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.
Use your fingers to carefully peel the three plastic tabs from the right side of the battery.

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