Introduction

If your Galaxy A3 won't hold a charge you can use this guide to replace the worn-out battery.

This guide involves removing the rear glass cover and the mid frame. You will need replacement adhesive to reattach the back cover to the phone.

Before disassembling your phone, discharge the battery below 25%. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged.
