Introduction

With our step-by-step photo guide you can easily replace the defective battery of your Galaxy S10 by yourself.

The repair is a bit more difficult, because the heavily glued glass backcover has to be removed to get to the battery. Removing the backcover may take a while, so plan enough time for the repair.

It is best to make a backup of all your data before the repair and only work on a clean and well-lit work surface. If you get stuck at a point, you can contact us via live chat and we will be happy to help.

10 steps
  1. Switching off your device

    1. Turn off your device by holding down the power button until the “Power off” option appears.
    2. Use your finger to confirm that you want to shut down your device and wait until the screen goes blank.

  2. Removing the back cover

    1. The back cover’s heavily glued to the chassis. Heat the device evenly with hot air to soften the glue. A temperature of 60 - 80°C should be sufficient. As a rule of thumb, you should still be able to touch your device without it being uncomfortably hot.
    2. The easiest way to loosen the back cover is to use a flat and flexible tool such as the iPlastix or iFlex. You will also need several picks to unstick the back cover all around.
    3. Heat the spot where you start and place a flat tool between the back cover and the frame.

    The iPlastix is made of plastic, so it won't scratch the device. On the other hand, it's very soft and tricky to insert. The iFlex makes it easier to get into the gap between the glass and the frame because it's made of very thin, stable metal. But it also makes it easier to scratch the frame of your device. To get into the gap initially, you can use the iFlex and then continue with the iPlastix as soon as possible.

    Be extra careful, the back cover can break very easily. If necessary, apply the heat several times and try again. Removing the back cover might take half an hour. Take a little more time and work carefully to make sure you don't break anything.

    1. Once the tool is inserted, stick a pick into the gap to keep it open. Then run the tool around the entire edge to gradually loosen the glue.
    2. Then heat the next part and insert the picks one by one.
    Use a suction cup to lift the glass if you can’t find anywhere to insert the tool.

    Be careful not to insert your tool too far and not to move the backcover too much back and forth while it is still lying down flat. An edge on the inside of the back cover can otherwise damage the pulse sensor cover.

  3. Removing the plastic cover

    • 8 × 3,9 mm Phillips
    1. Loosen the Phillips screws that secure the cover. The contactless charging coil and NFC antenna are attached to the plastic cover.
    2. The cover is hooked into the top of the housing and the lower part is lightly glued on. Carefully slide a flat tool under the attached areas and loosen them.
    3. Now you can remove the cover together with the coil.
  4. Disconnecting the battery

    • Battery connector
    1. Using the spudger, carefully disconnect the battery contact from the motherboard.

    Always lever from a side where there are no small components on the motherboard. This avoids unintentional damage to capacitors or ICs.

    The battery is strongly glued, so you should use hot air again to loosen the glue. The glue is on the edge of the battery but not in the middle.

    Never heat the battery directly and avoid bending it.

    1. Heat the battery from below via the display.
    2. We recommend using a flat tool like the iPlastix or an iSesamo to go around the battery and lever it carefully.
    3. When the glue is loosened everywhere, lift the battery and remove it from the device.

    If you only replace the battery, be careful not to insert the tool too far to avoid damaging the back of the display.Be careful not to damage the battery. Take your time again and heat the glue several times.


  6. Preparing the battery

    1. Remove all adhesive residues so the new battery can sit evenly in the device and is not pushed upwards.
    2. Remove all protective films over the adhesive surfaces of your new battery.

    If your new battery doesn't have new adhesive surfaces, you can use thin double-sided tape to fix the battery back in it's place. However, stick nothing on the black back of the display, but only on the metal frame at the edge.

  7. Inserting the battery

    1. Put the battery in the display unit.
    2. Press the battery firmly into the frame so the glue will stick better.
  8. Connecting the battery

    • 8 × 3,9 mm Phillips
    1. Put the cover with the antenna back in the enclosure after hooking it onto the top of the enclosure.
    2. Then press the cover with your fingers until it clicks gently into place.
    3. Fasten the phillips screws.
  10. Attaching the back cover

    If the adhesive on the back cover is still intact, you can seal your device without using a new adhesive frame.

    1. Put the back cover back in its original position.
    2. Press the back cover on all over so the glue will stick.

    You can also heat your device with hot air and then clamp it or weight it down with a couple books so the glue will stick better.

    If you install a new backcover, now remove the last protective films from the adhesive surfaces.
