5 steps
  1. Removing the back cover

    1. The back of the Sony Xperia Z3’s enclosure is glued firmly in place. To detach it, you have to constantly heat it with a heat gun so the glue will soften. Then you have to insert a plastic pick into the gap between the frame and the glass to detach the adhesive.
    2. The gap between the aluminum frame and the glass is very small. We recommend that you use a very flat, sturdy object to get between them.
    3. Carefully lift the back cover while using a suction cup.
    4. As soon as a little gap opens up, use the plastic pick to avoid damaging the aluminum.
  2. Inserting the pick

    1. You should only insert the pick a few millimeters between the back cover and the frame to prevent damage inside the enclosure.
      The back cover is painted on the inside. Remove any adhesive residue carefully to avoid scratches or cracks.
    2. The back cover is glued to the entire outer edge of the Sony Xperia Z3. Move the pick once around the entire phone. There are also two removable adhesive strips attached to the battery. You can’t pull them off until you lift the top.
    3. Once you’ve detached all the glue, you can carefully lift the back cover.
  3. The right tools for your repair

    With the right tools, you will succeed in any repair. In our store you will find a large selection of professional quality tools.

    1. Place the pointed tip of the spudger very slightly below the contact and lift it up. Make sure you don’t break off the resistors that are soldered onto the logic board.
    2. Now slowly lift up the battery. It’s only lightly glued in place.
    3. Then remove it.
  5. Installing the battery

    2. The old glue is usually still sticky enough.
    3. Put the back cover back on, heat it slightly and then use a little force to press it onto the smartphone for a while.
