Samsung Galaxy Note20 Battery Replacement - Samsung Galaxy Note20

Step 1 | Heat the rear cover

Completely power off your phone before starting disassembly.

Apply an iOpener to the left side of the rear cover for one minute.
Alternatively, use a hair dryer, heat gun, or hot plate to warm the area carefully (be cautious not to overheat and damage the phone's screen, internal battery, or plastic rear cover).

Step 2 | Insert an opening pick

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

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

Depending on your phone's age, this may be difficult. If you encounter issues, reapply heat and try again.

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

Step 3 | Begin to cut the adhesive

Do not insert the pick more than 5 mm into the phone's adhesive to avoid damaging internal components.

Slide the opening pick along the left edge towards the bottom left corner to cut through the adhesive.
Leave the pick inserted in the bottom left corner after cutting to prevent re-sealing of the adhesive.

Step 4 | Cut along the perimeter of the rear cover

Heat and cut the adhesive along the three remaining sides of the rear cover.
Insert new opening picks into the gaps created by previous picks in each corner.
Leave a pick in each corner to prevent re-sealing as you proceed.

If still attached, try slicing through adhesive again with an opening pick.

Step 5 | Remove the rear cover

Lift the rear cover straight up to release it.

Step 6 | Remove the motherboard shield

Screws with threadlocker may require extra effort for removal.

Remove the six 4.0 mm screws securing the motherboard shield using a Phillips screwdriver.
Keep track of each screw and ensure it is returned to its original location.

Step 7

Handle the motherboard shield with care, as its edges are thin and sharp.

Use a pair of tweezers to lift up and flip back the motherboard shield.

Step 8 | Disconnect the battery

Avoid damaging socket and components by prying only under edge of the connector.

Hold motherboard shield out of way using tweezers.
Pry up battery press connector with pointed end of a spudger.

Do not press down on middle; misaligned pins can bend and cause permanent damage.

Re-attach by aligning and pressing one side until it clicks, then repeat on other side.

Step 9 | Disconnect the wireless charging coil

Hold the motherboard shield away with a pair of tweezers.

Pry up the wireless charging coil press connector using the pointed end of a spudger.

Step 10 | Remove the wireless charging coil

Grasp the motherboard shield carefully with your fingers.

Pry the wireless charging coil upwards, loosening its hold on the device.
The wireless charging coil is secured by light adhesive; be cautious not to damage it.
Remove the wireless charging coil.

Step 11 | Unscrew the loudspeaker

Unscrew the 5 x 4.0 mm screws using a Phillips screwdriver.

Step 12 | Remove the loudspeaker

Careful not to damage the battery.

Insert the spudger near the top left screw hole of the loudspeaker and pry it up from the frame.
Use tweezers to lift and remove the loudspeaker.

Avoid puncturing or bending the battery, as this may cause leakage or a thermal event.

Step 13 | Disconnect the interconnect cables

Disconnect the main interconnect cable using the pointed end of a spudger.

Step 14

Use the pointed end of a spudger to disconnect the secondary interconnect cable from the daughterboard.

Step 15

Disconnect the secondary interconnect cable from the motherboard using the pointed end of a spudger.

Step 16

Disconnect the main interconnect cable from the motherboard using the pointed end of a spudger.

Step 17 | Disconnect the display cable

Disconnect the display cable from the motherboard using the pointed end of a spudger.

Step 18 | Move the cables

Excessive bending of ribbon cables can cause damage.

Flip the secondary interconnect cable away from the battery, keeping the attached ribbon cable loose but intact.

Step 19

Bend the main interconnect cable back for access to the battery.
Bend the display cable back and remove it from your work area.

Step 20 | Apply isopropyl alcohol

Excessive isopropyl alcohol may damage the display.

Apply 1-2 drops of high-concentration (90% or higher) isopropyl alcohol to each corner of the battery.
Wait two minutes for the adhesive underneath the battery to weaken.

Step 21 | Remove the battery

Attach a suction cup to the center of the battery.

Step 22

Bending the battery can cause a thermal event or leak hazardous chemicals.

Apply steady force to the suction cup to create a gap between the battery's bottom edge and the frame.
If separation is difficult, apply more drops of isopropyl alcohol and wait two minutes before retrying.

Step 23

Insert opening pick into gap between bottom edge of battery and frame.

Push opening pick under battery to cut through adhesive and detach from frame.

Do not insert opening pick more than halfway to avoid damaging fingerprint sensor.

Do not attempt to forcefully lever battery out; apply additional drops of alcohol if necessary.

Step 24

Never reuse a battery that's already been removed — risk of electric shock and damage.

Pull up on the suction cup to remove the battery.
Use isopropyl alcohol to loosen battery adhesive; the battery will come out easily once penetrated.
Before reassembly, wipe off or let dry any remaining isopropyl solution in the phone.
Replace old adhesive with stretch release adhesive strips, double sided tape, or pre-cut adhesive for new battery.
