Introduction

Use this guide to replace the old battery in your Sony Xperia Z3.

Heat the back cover of your Xperia Z3 to loosen the adhesive underneath. Lift up the back cover with a suction handle and put an opening pick in the gap. Move the pick carefully around the edges to loosen the adhesive on every side of the phone.

  • Move the pick carefully around the edges to loosen the adhesive on every side of the phone.

  • Don't put the pick in too deep under the back cover to not damage any parts inside the phone.

How hot (how many C) should the iOpener be? I think it would be safer / more accurate to heat the iOpener in an oven with accurate temperature control.

Careful here. The back cover cracked in two places. Once when I exerted pressure with the suction handle, and in the corner when moving the pick around the edges- even though I was very gentle. The battery was adhered firmly to the back cover.

After the adhesive around the egdes is loosened, pull up the back cover with your suction handle. Use a tweezer to pull out two black straps that are attached to two pieces of adhesive right on the battery.

Gently pull out both of the black straps with the adhesive tabs. Never pull out the straps upwards but always sideways. It can easily happen that you rupture the adhesive tabs right in between. In this case use a plastic card to pry off the back cover carefully, use heat if necessary !

En hoe krijg je ‘m dan weer goed dicht?

If the original tape won’t hold anymore, you could replace it with double sided adhesive tape to reseal the back cover. Take a look here:

Tesa 61395 Tape

or directly in the EU Store for shipping to the Netherlands:
