In this detailed photo tutorial, we will show you step by step how you can easily replace your battery yourself.

Once you open your device, the specified IP certification (protection against dust and water ingress) will expire.If your battery is inflated, keep in mind that the gas inside the battery is flammable and can escape. If you do not feel confident enough, have it replaced at a repair shop.

  3. Lifting up the back cover

    To detach the back cover, we recommend using a thin, sturdy tool like the iFlex.

At the same time, insert the iFlex between the screen unit and the back cover.

    To avoid damaging the edge of the case with the sharp edges of the iFlex, you should switch to a plastic tool like the iPlastix as soon as possible.

    Be extra careful when loosening around the camera module, so you don't damage it with your tool.

    1. Drive the tool completely around the edge of the back cover to loosen it piece by piece. Heat the adhesive again in between.
    2. Slide flat picks under the back cover at regular intervals, so that the glue cannot bond again.

    1. Heat the adhesive frame with hot air to make it easier to remove from the inside of the back cover.
    2. Pull it off bit by bit with a pair of tweezers.
