Introduction

If your Galaxy A3 won't hold a charge you can use this guide to replace the worn-out battery. If your battery is swollen, take appropriate precautions.

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.

  1. Start by switching off your phone. Take an iOpener to heat up and soften the glue behind the back cover. Lift the bottom part of your back cover with a suction handle and insert an opening pick.

Nice post on Samsung phone. People are courageous about Galaxy phones and there is lot of hype about Samsung.

I bought a budget j7 for my wife and I am sure this will have good review.

not sure why they are not talking about.

Thanks

Thank you so very much! I'm an ageing priest working in Transylvania and The Republic of moldova with victims of child trafficking. My battery has suffered extensive use and I believe it still should have lasted longer. I have limited resources to use for myself and feel attempting to replace the battery myself far more economical and funds conscious. Thanks to you I shall endeavour to replace it myself…thanks to your instruction.

May all your journeys be ones of discovery!

Assolutamente insufficiente. L’iOpener non scioglie l’adesivo posteriore e quindi il vetro posteriore si rompe facilmente. Il tutorial indica una parte assolutamente inutile, ovvero lo smontaggio del telaio. Non serve basta estrarre la batteria con un piccolo cacciavite. I tutorial fateli scrivere a chi lavora sui device. Grazie

Hello axlduri,

thanks for your feedback. In case you weren’t able to loosen the adhesive beneath the back cover with an iOpener, you can use a heat gun to do so. However the iOpener should do the job and should be applied for at least 2 minutes to the back cover. Repeat this step several times until the adhesive is loose. Additionally the battery sits super tight in the mid frame and it’s nearly impossible to remove it safely, without removing the mid frame. You should never work or pry on batteries with metal tools like a screwdriver. If you accidentally puncture them, they can explode or catch fire. Thats the reason why we advise to remove the mid frame. It’s the safest way to remove the battery.
