HMD Fusion Battery Replacement

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.
