Samsung Galaxy Note20 Ultra Battery Replacement

Power off your phone completely before disassembling.

• Apply an iOpener to the left side of the rear cover for one minute.
• Alternatively, use a hair dryer, heat gun, or hot plate, but exercise caution to avoid overheating and damaging the screen or internal battery.

Apply a suction cup to the heated edge of the rear cover, as close to the edge as possible.

• If your back glass is badly cracked, covering it with clear packing tape may help the suction cup adhere.
• Alternatively, use strong tape instead of the suction cup or superglue it to the broken panel if necessary.

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

Depending on your phone's age, this may be difficult; apply more heat and try again if needed.

• Insert an opening pick into the gap, but do not insert it more than 5 mm to avoid damaging internal components.

Insert a credit card or similar tool into the device near the top and gently work it down the left side, stopping at the bottom left corner.

• Leave the pick in place to keep the adhesive separated, preventing re-sealing.

Insert opening pick no more than 5 mm into phone to avoid damaging internal components.

• Heat and cut adhesive along three remaining sides of rear cover, repeating process as needed.
• In each corner, insert new opening pick in gap created by previous pick and leave one pick per corner.
• Slide an opening pick around entire perimeter to release any missed adhesive, reheating stubborn areas as necessary.

Remove rear cover by lifting it straight up.

Careful: prying under the edge only prevents socket damage.

• Use a spudger to pry up and disconnect the wireless charging coil press connector, applying pressure only along its edges.
• When re-attaching, align carefully and press down on one side until it clicks, then repeat on the other. Avoid pressing the middle.

Misaligned connectors can cause pin bend and permanent damage.

Use the pointed end of a spudger to carefully pry up the white press connector at the bottom right of the motherboard shield.

Use a Phillips screwdriver to remove the six 4.0 mm screws securing the motherboard shield.

These screws may be difficult to remove if threadlocker has been applied, so proceed with caution.

• Label each removed screw for correct reassembly later.
• Keep track of the location of each screw to ensure it is replaced in its original position.

Use a tweezers to lift up the motherboard shield.

Handle the motherboard shield with care, as its thin edges can be sharp.

• Maintain a safe distance to access the battery, as it is still connected by a ribbon cable.

Bend the display cable back to gain access to the battery.

• Bend the main interconnect cable out of the way.

Excessive use of high-concentration isopropyl alcohol can damage the display.

• Apply 1-2 drops of strong (90% or higher) isopropyl alcohol to each corner gap in the battery.
• Allow 2 minutes for the adhesive underneath the battery to weaken from the isopropyl alcohol.

Attach a suction cup to the center of the battery.

Apply steady force with the suction cup to create a gap between the battery and frame.

Beware of bending the battery, which may cause chemical leaks or thermal events.

• Check for separation; if not, apply more isopropyl alcohol and wait two minutes before retrying.
• Multiply this process as necessary due to the strong adhesive underneath the battery.

Insert the point of an opening pick into the gap between the battery's bottom edge and the frame.

• Pry under the battery to cut through the adhesive and detach it from the frame.
