Samsung Galaxy S20 Plus Battery Replacement

Unplug your phone and power it off.

• iOpener: Heat for two minutes and apply to the back cover's bottom edge.
• Alternatively, use a hair dryer, heat gun, or hot plate; however, be cautious not to overheat your phone as the display and internal battery are prone to heat damage.

Apply a suction cup to the phone's back, near the center of the bottom edge.

• If the display is badly cracked, cover it with clear packing tape for better adhesion.
• Alternatively, use strong tape or superglue the suction cup to the broken glass if needed.

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

• Insert an opening pick into the gap once it's created.
• Reheat with the iOpener and try again if necessary due to tight tolerances.

Avoid applying excessive force with the pick, which can crack the back cover glass.

If trouble persists, apply more heat and try again.

Risk of cracked glass if cutting near curved edges.

• Slide a pick back and forth along the bottom edge to slice through the adhesive.
• Avoid cutting near corners where the glass is curved to prevent cracking.
• Leave your pick in the seam to keep the adhesive from resealing.

Apply a iOpener to the left edge of the back cover for 2 minutes.

Apply a suction cup to the left edge, close to center.

• Pull on the suction cup with strong, steady force to create a gap.
• Insert an opening pick into the gap, just beneath the curved glass edge.

Due to tight tolerances, this may take multiple attempts.

Apply gentle heat and isopropyl alcohol (over 90% concentration) if needed.

Avoid applying excessive force with the pick, or you risk cracking the glass.

Position the pick under the glass's edge.

• Tilt it downward and push further in to break the adhesive.

Be cautious around the frame's ridge near the volume and power buttons, as the glass cutout can crack.

• Slide a pick along the left edge of the phone to loosen the back cover's adhesive.
• Position the pick under the left edge of the glass after removal to prevent re-adhesion.

Risk of heat damage to the display and internal battery.

• Apply a heated iOpener to the right edge of the back cover for two minutes.
• Alternatively, use a hair dryer, heat gun, or hot plate, but be cautious not to overheat the phone.

• Apply a suction cup to the right edge of the phone, near its center.
• Pull on the suction cup with strong force to create a gap between the back cover and frame.
• Insert an opening pick into the gap; tilt it downward for full insertion under the back cover.

Slide a pick along the right edge of the phone to separate the back cover's adhesive.

Leave the pick under the glass near the top to prevent resealing.

• If other picks fall free, set them aside as the bottom edge shouldn't reseal further.

Apply a iOpener to the top edge of the back cover for 2 minutes using heat.

Be gentle when handling the curved glass near the corners of the back cover, as it is prone to cracking.

• Start by sliding a pick from the right edge around the top right corner, gradually applying more pressure.
• Continue slicing along the top edge, moving clockwise until you reach the left edge to fully separate the adhesive.
• If the process becomes difficult, stop and reapply heat before resuming.

Disconnect power to prevent accidental start-up.

• Lift the back cover slowly and use opening picks to remove any remaining adhesive.
• Remove the back cover.

Power your phone back down completely before proceeding.

• Remove any remaining adhesive chunks with tweezers or fingers. Apply heat if necessary for separation.
• If using custom-cut adhesives, consult the relevant guide.
• If using double-sided tape, consult the relevant guide.

Remove the six 4 mm screws using a Phillips #00 screwdriver.

• Set aside each screw to ensure correct reinstallation.
• Label or number each screw for easy identification later.

Use tweezers to gently pull up and unclip the motherboard bracket from the plastic midframe.

Do not remove it completely yet, as it is still attached to the wireless charging coil.

Slowly lift the motherboard bracket to clear the orange battery connector.

Risk of damage when handling surface-mounted components.

• Use a spudger to pry up and remove the battery connector.
• Be cautious not to dislodge surrounding surface-mounted components.

Remove the wireless charging coil connector by prying it loose with a spudger.

Use a pair of tweezers to gently peel the wireless charging coil away from the device.

• Remove the wireless charging coil.

During reassembly, reconnect the charging coil and battery connectors, then refasten the motherboard bracket screws. Finally, firmly press the coil pad down to adhere it.

• Remove the loudspeaker and lower midframe using a Phillips #00 screwdriver.
• Loosen all five 4 mm-long screws securing it.

Locate the notch in the top left corner of the midframe.

• Pry up the midframe using a spudger or tweezers, starting from the identified notch.

Be cautious not to damage surrounding components.

• Remove the loudspeaker and lower midframe.

Risk of damage to delicate connectors.

• Use a spudger to pry up and disconnect the main and auxiliary flex cables from the daughterboard near the bottom.
• To reattach press connectors, carefully align them and press down on one side until they click into place.

Misaligned connectors can bend pins causing permanent damage — do not press in the middle.

Remove the main and auxiliary flex cables using a spudger.

• Pry up on the main flex cable connector.
• Gently disconnect the auxiliary flex cable from the motherboard.

Remove the main and auxiliary flex cables by gently peeling them up.

Disconnect the left 5G antenna cable from the motherboard using a pry tool.

Disconnect the main display flex cable from the motherboard using a spudger.

Peel up the display flex cable and left 5G antenna flex cable, gently bending them aside to clear the path for the motherboard and battery.

Excessive use of isopropyl alcohol can damage the display.

• Apply 1-2 drops of high concentration (over 90%) isopropyl alcohol to the gaps between the frame and battery edges.
• Allow 1 minute for the alcohol to soften the adhesive before proceeding.

Apply a suction handle to the center of the battery.

• Hold the device firmly with one hand, bracing the top and bottom against your work surface.
• Pull up on the suction handle with steady force for 15 seconds at a time. Repeat as needed.

If the battery doesn't loosen, apply 1-2 drops of isopropyl alcohol along the top, left, and right edges, wait one minute, then pull again.

• Continue pulling until the battery begins to lift from the device.

Do not proceed until the battery is lifted enough for a pick to be inserted easily — risk of piercing the battery.

• Insert an opening pick under the bottom edge of the battery, then twist to loosen the adhesive.
• Do not apply isopropyl alcohol yet; it may damage your screen's fingerprint sensor if applied too soon.

Remove the battery.

Prevent potential safety hazards by never reusing batteries that have been removed.

• Peel up and scrape away any remaining adhesive from the battery well.
• Clean the area with isopropyl alcohol and a lint-free cloth.

Wait at least ten minutes after cleaning to allow complete evaporation of any solvents before installing the new battery.

• If not pre-applied, apply adhesive to the well and install the new battery.
• Firmly press the new battery into place during reassembly.
