This guide shows how to remove and replace the battery for the Samsung Galaxy S20 Ultra.

The battery is held in place with strong adhesive. High concentration (over 90%) isopropyl alcohol is necessary to loosen and release this adhesive.

If your battery is swollen, take appropriate precautions and do not heat your phone.

For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

  1. Unplug and power off your phone before you begin.
    • 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. Apply a suction cup to the back of the phone, as close to the center of the bottom 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.
    • Apply a suction cup to the back of the phone, as close to the center of the bottom 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.

    • 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, your best bet is to apply more heat to the edge and try again.

    • You can also try 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 will risk cracking the back cover glass.

  3. 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.

    • 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, your best bet is to 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 will risk cracking the back cover glass.
