  1. Samsung Galaxy S20 Ultra Battery Replacement, Heat the bottom edge: crwdns2935265:01crwdnd2935265:01crwdnd2935265:01crwdne2935265:0
    • Unplug and power off your phone before you begin.

    • Heat an iOpener and apply it to the back cover's bottom edge for two minutes.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.

  2. Samsung Galaxy S20 Ultra Battery Replacement, Separate the bottom edge adhesive: crwdns2935265:02crwdnd2935265:01crwdnd2935265:03crwdne2935265:0 Samsung Galaxy S20 Ultra Battery Replacement, Separate the bottom edge adhesive: crwdns2935265:02crwdnd2935265:02crwdnd2935265:03crwdne2935265:0 Samsung Galaxy S20 Ultra Battery Replacement, Separate the bottom edge adhesive: crwdns2935265:02crwdnd2935265:03crwdnd2935265:03crwdne2935265:0
    • Apply a suction cup to the back of the phone, as close to the center of the bottom edge as possible.

    • If the back cover is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken cover.

    • Pull on the suction cup with strong, steady force to create a gap between the back cover and the frame.

    • Insert the point of an opening pick into the gap.

    • Due to tight tolerances, this may take multiple attempts of reheating with the iOpener and separating with the suction cup before you get it right.

    • If you are having trouble creating a gap, apply more heat to the edge and try again.

    • Do not apply excessive force with the pick, or you risk cracking the back cover glass.

  3. Samsung Galaxy S20 Ultra Battery Replacement, Slice the adhesive: crwdns2935265:03crwdnd2935265:01crwdnd2935265:03crwdne2935265:0 Samsung Galaxy S20 Ultra Battery Replacement, Slice the adhesive: crwdns2935265:03crwdnd2935265:02crwdnd2935265:03crwdne2935265:0 Samsung Galaxy S20 Ultra Battery Replacement, Slice the adhesive: crwdns2935265:03crwdnd2935265:03crwdnd2935265:03crwdne2935265:0
    • Slide the pick back and forth along the bottom edge to slice through the adhesive.

    • Do not attempt to cut the adhesive near the corners of the phone where the glass is curved or you risk cracking the glass panel.

    • Leave your opening pick in the seam to prevent the adhesive from resealing.

  4. Samsung Galaxy S20 Ultra Battery Replacement, Heat the left edge: crwdns2935265:04crwdnd2935265:01crwdnd2935265:01crwdne2935265:0
    • Apply a heated iOpener to the left edge of the back cover for two minutes.

  5. Samsung Galaxy S20 Ultra Battery Replacement, Separate the left edge adhesive: crwdns2935265:05crwdnd2935265:01crwdnd2935265:03crwdne2935265:0 Samsung Galaxy S20 Ultra Battery Replacement, Separate the left edge adhesive: crwdns2935265:05crwdnd2935265:02crwdnd2935265:03crwdne2935265:0 Samsung Galaxy S20 Ultra Battery Replacement, Separate the left edge adhesive: crwdns2935265:05crwdnd2935265:03crwdnd2935265:03crwdne2935265:0
    • Apply a suction cup to the back of the phone, as close to the center of the left edge as possible.

    • Pull on the suction cup with strong, steady force to create a gap between the back cover and the frame.

    • Insert the point of an opening pick into the gap.

    • As the glass on this edge is curved, you won't be able to insert this pick very far. As long as the very tip of the pick is underneath the glass's edge, you will be able to proceed.

    • Due to tight tolerances, this may take multiple attempts.

    • If you are having trouble creating a gap, apply more heat to the edge and try again.

    • You can try also applying a few drops of high concentration (over 90%) isopropyl alcohol into the seam to help loosen the adhesive.

    • Do not apply excessive force with the pick, or you risk cracking the back cover glass.

    • Insert another pick under the center of the left edge of the back cover.

    • Gradually slide the pick towards the top of the device to separate the back cover's adhesive.

    • Take care when sliding across the ridge in the frame surrounding the volume and power buttons—the cutout in the glass may make it more prone to cracking.

    • Leave your pick under the left edge of the glass near the top of the device to prevent the adhesive from resealing.

    • Apply a few drops of high concentration (over 90%) isopropyl alcohol to the gaps in between the frame and the edges of the battery.

    • Do not apply too much isopropyl alcohol. Use a pipette and only apply a few drops at a time, only at the edges of the battery. Too much alcohol can damage the screen underneath.

    • Tilt the device gently as you apply the alcohol help it penetrate the adhesive underneath the battery.

    • After you apply the alcohol, continue tilting the phone gently in all directions for three to five minutes to help the alcohol penetrate further and evaporate.

    DO NOT DO THIS. This step will destroy your screen. Alcohol seeps into the screen through a hole under the battery compartment. This will dissolve critical components of the screen and cause it to fail.

    Nick Graham - crwdns2934203:0crwdne2934203:0

    This section needs to be updated with new photos showing the correct way of removing the battery: using heat. I myself have tried to remove my battery with alcohol, and because of the wording the guide had before, I used too much and my screen and motherboard were completely destroyed.

Daniele Carminati -

Where did you buy this battery, avoid ebay only buy from trusted sources with warranty like ifixit

I bought a galaxy s7 battery on eBay claiming to be original quality it swelled up badly in 2 days

James middleton -

I completed this repair yesterday and for awhile everything was working. Now it looks like there’s residual isopropyl alcohol in the camera assembly and the screen is no longer working. For awhile touch input stopped but the display remained and now the display has stopped as well. I’m worried I damaged something by using too much alcohol when getting the battery out, or maybe on the display cable when reattaching it during reassembly. How do I go about finding out what the issue is and hopefully fix it?

Michael Miller - crwdns2934203:0crwdne2934203:0

This exact issue happened to me as well, word for word how you put it. Took my phone to a repair store and they said the motherboard was damaged and there was nothing they could do. The wording this guide had before was extremely dangerous and probably killed a lot of people's phones.

Rex Hughes -

Thanks for bringing this up! I'm sorry to hear about the damage during repair. We'll look into the procedure and update it.
