Introduction

If your Sony WF-1000XM3 earphones no longer charge or have a significantly shorter battery life, use this guide to replace the batteries.

Before using this guide, check to see if the charging pins are dirty or damaged. If they are dirty, a small amount of contact cleaner may potentially fix the problem.
