Galaxy S20 - Battery replacement

1. Switch off the device at the beginning to avoid short circuits during the repair.

If the screen can no longer be used due to damage, the device is switched off by disconnecting the battery.

The Samsung Galaxy S20 is opened via the heavily bonded glass back cover.

1. Heat the frame of the device with hot air to about 60-80 degrees. Heating it makes the backcover's adhesive easier to remove.
2. Take a suction cup and place it on the bottom of the device.
3. Pull the suction cup and guide your flat opening tool into the resulting gap.

The iFlex opening tool, which is made of thin, strong metal, is very suitable for removing such glued back covers. Once inserted, we recommend using a plastic tool, as this will not scratch the frame and back cover.You can also use an iSclack instead of a suction cup. This tool works like a pair of pliers with suction cups on both sides.

1. Insert a narrow plectrum into the already loosened part so that the glue does not reattach.
2. Guide your tool along the entire edge of the back cover.

Warm up the tool from time to time and work carefully to avoid breaking the glass. This step takes some time.

1. In the area of the camera you should also take care not to insert your tool too far into the device.

Please note: Once the device has been opened for the first time, a hundred percent protection against the ingress of dust and liquids can no longer be guaranteed.

• 5 × 4,0 mm Phillips

1. Remove the Phillips screws of equal length from the charging coil.

An iDoc magnetic pad can help you sort screws and smaller components.

1. The coil is slightly glued to the speaker. Loosen the glue and remove the cover. It is slightly hooked at the top end.

• Battery Connector

1. Now disconnect the battery with a plastic spudger.

Pay attention to the small components next to the battery connector. Lever from the other side to avoid accidentally damaging them.

• 5 × 4,0 mm Phillips

1. Loosen the Phillips screws that secure the speaker in the unit.
2. Then lift up the speaker and take it out.

• Connector

1. Loosen and remove the flex cables that run over the battery.
2. Separate the connectors carefully with the spudger and take out the two upper cables.
3. Then disconnect the display cable from the motherboard.

1. The battery is strongly glued. You should use hot air again to loosen the glue more easily.

Never heat the battery directly, but from underneath via the screen.

1. Fold the display flex cable that runs above the battery to the side. If necessary you can fix it to prevent it from getting in the way while removing the battery.
2. Use a tool such as the iSesamo or a battery supdger to lever.
3. Lever with the tool around the battery to release it bit by bit.
4. Do not bend the battery and take care not to pinch the battery or damage its cover.
5. Once the glue is slightly loosened, you can use a flat plastic tool such as the iPlastix to slide beneath the battery.
6. Take enough time for this step and warm up the glue in between.
7. Once the adhesive is loosened, you can remove the battery from the device.

1. Remove any adhesive residue remaining in the unit. This will prevent your new battery from sitting improperly inside the device and being pushed up by adhesive residue.
   
2. Then remove all protective films from the adhesive surfaces of your new battery.
3. If there is no adhesive surface on your new battery, you can use very thin double-sided adhesive tape or our universal adhesive strips.

1. Then insert the battery into the device. Make sure that it has a little space on all sides and is not pushed against the frame anywhere.

• Connector

1. Reinsert the flex cables that run above the battery.
2. The side labeled "MAIN" should face up inside the unit.
3. Connect the connectors to the main board and the USB board.

• 5 × 4,0 mm Phillips

1. Insert the speaker, press it down and screw it in place. Make sure it's hooked in at the bottom.

• Battery Connector

1. Position the battery contact over its socket on the mainboard and press it down.

• 5 × 4,0 mm Phillips

1. Put on the metal cover with the charging coil.
2. Hook it in at the top and fasten all screws.

1. Test your Galaxy S20 before you finally close the device.
2. Switch on the device and open the telefone app.
3. Here you enter *#0*# and a test menu opens.
4. In the test menu you can test the display for pixel errors and check the touchscreen and other functions such as the camera, the speaker or the status LED.
5. If everything is OK, you can lock your smartphone for good.

1. Before you put the backcover back on you should check the glue. It should be evenly distributed on the edge of the backcover. Remove excess glue if necessary.
2. If you like, you can also remove the old glue and use a new one.

Please note, that even with a new adhesive frame a 100% protection against the ingress of dust and liquids can no longer be guaranteed.

1. Before attaching a new adhesive frame, you must first remove all old adhesive residues on the backcover and frame. You can use a plastic supdger to scrape off some of the glue. Cleaning alcohol and a lint-free cloth can help to remove the residue.
2. Check the alignment of the frame, then peel off the first protective film and apply the adhesive to the frame. Don't press it down yet, but check that it is properly seated on all sides. The adhesive should not protrude at anywhere.
3. Press the adhesive down all around so that it bonds properly to the frame.
4. Loosen the second foil. Make sure that the adhesive does not come off the frame.
5. Position the backcover over the device and put it down slowly.
6. Heat the backcover again with hot air so that the adhesive bonds again.
7. As long as the glue cools down, you can press the backcover down with your fingers or weight it down with a few books.
