Introduction

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

Image 1/3: Lift up the back cover with a suction handle and put an opening pick in the gap. Image 2/3: Move the pick carefully around the edges to loosen the adhesive on every side of the phone. Image 3/3: Don't put the pick in too deep under the back cover to not damage any parts inside the phone.
  • 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.

  • 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.

Image 1/2: 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 ! Image 2/2: Never pull out the straps upwards but always sideways.
