Samsung Galaxy S24+ Battery Adhesive

Step 1

Allow your phone's battery to drain below 25%, as a charged lithium-ion battery is a potential safety hazard. If your battery is swollen, take appropriate precautions.
Unplug any cables from your phone.
Hold the side key and the volume down button, then select "Power off" to turn off your phone.

Step 2

Heat an iOpener and apply it to the right edge of the back cover 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 susceptible to heat damage.

Step 3

Apply a suction handle to the back cover, as close to the center of the right edge as possible.
Pull up on the suction handle with strong, steady force to create a gap between the cover and the frame.
If you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
Insert an opening pick into the gap.

Step 4

Slide the pick back and forth along the right edge to separate the adhesive.
Leave the pick inserted near the bottom right corner to prevent the adhesive from resealing.

Step 5

Apply a heated iOpener to the bottom edge of the back cover for two minutes.

Step 6

Rotate the opening pick around the bottom right corner to separate the adhesive.

Step 7

Insert a second pick at the bottom right corner.
Slide the opening pick to the bottom left corner to separate the adhesive.
Leave the pick in the bottom left corner to prevent the adhesive from resealing.

Step 8

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

Step 9

Rotate the opening pick around the bottom left corner to separate the adhesive.

Step 10

Insert a third opening pick at the bottom left corner.
Slide the pick toward the top left corner to separate the adhesive.
Leave the pick near the top left corner to prevent the adhesive from resealing.

Step 11

Apply a heated iOpener to the top edge of the back cover for two minutes.

Step 12

Rotate the opening pick around the top left corner to separate the adhesive.

Step 13

Insert a fourth opening pick at the top left corner.
Slide the pick toward the top right corner to separate the adhesive.
Leave the pick near the top right corner to prevent the adhesive from resealing.

Step 14

There's a square of adhesive around the rear microphone, just above the flash.
Line up the tip of an opening pick with the flash.
Slide the opening pick under the top of the back cover until you feel it start to snag on the adhesive.
Keep sliding the pick toward the bottom of the phone while gently lifting the cover until the cover is free of the adhesive.

Step 15

Grab and remove the back cover.
If the back cover is not lifting easily, use an opening pick to separate any adhesive that may have resealed.
During reassembly:
This is a good point to power on your phone and test all functions before sealing it up. Be sure to power your phone back down completely before you continue working.
Retaining water resistance after the repair will depend on how well you reapply the back cover adhesive, but your device will lose its IP (Ingress Protection) rating.
Use tweezers or your fingers to remove all adhesive from the back cover and the phone. Use heat or isopropyl alcohol (90% or greater) and a coffee filter or lint-free cloth if you're having trouble removing the adhesive.
If you're using custom-cut adhesives, follow this guide.

Step 16

Use a spudger to pry up and disconnect the wireless charging coil press connector from the motherboard.
There's an arrow printed on the board near each press connector that indicates the recommended prying location.
To reconnect press connectors, align the connector carefully over its socket and press down with your fingertip—first on one side, then the other—until it clicks into place. Don't try to force the connector into place. If you're having trouble, reposition it and try again.

Step 17

Use a Phillips screwdriver to remove the thirteen 3.5 mm‑long screws securing the wireless charging coil and the loudspeaker:
Six screws securing the wireless charging coil
Seven screws securing the loudspeaker

Step 18

Insert the point of a spudger in the notch at the top left corner of the loudspeaker, which is marked by an arrow.
Pry up to unclip the loudspeaker from the frame.

Step 19

Use your fingers to lift the loudspeaker away from the frame.
Remove the wireless charging coil and loudspeaker from the frame.
During reassembly, press around the edges of the loudspeaker to clip it to the frame before reinserting the screws.

Step 20

Use a spudger to pry up and disconnect the battery press connector.

Step 21

Use a spudger to pry up and disconnect both interconnect cable press connectors from the daughterboard.

Step 22

Use a spudger to pry up and disconnect both interconnect cable press connectors from the motherboard.

Step 23

Grab and remove the interconnect cables from the phone.

Step 24

Use a spudger to pry up and disconnect the display cable and lower antenna cable press connectors from the motherboard.

Step 25

Use a spudger to pry up and disconnect the display cable press connector near the bottom edge of the phone.
Remove the display cable.

Step 26

Push the battery and antenna cables out of the way of the battery.

Step 27

Be very careful not to bend, crease, or puncture the battery during the next few steps. A damaged battery can leak dangerous chemicals and catch fire.
Peel the battery pull tab away from the battery, towards the left edge of the phone.
If you're having trouble getting the pull tab up, use and opening pick or other thin plastic tool at a low angle to peel up a corner. Never use a metal tool on battery, and never press into the battery.

Step 28

Separate the small, clear tabs above and below the blue part of the pull tab from the rest of the pull tab.
Bend these small tabs away from the battery to make sure they stay clear of the battery.
If these tabs aren't separated, you won't be able to lift the battery in the next step. You can tape these tabs to the side of the phone or the screen to keep them out of the way.

Step 29

This battery is held by a piece of double-sided adhesive film that is doubled under the battery. When you lift the battery by the pull tab, the left edge will come up, but the right edge will not. You'll remove the remaining film and the battery in the next step.
With one hand firmly holding down the frame of the phone, use firm, steady force to lift the blue pull tab straight up until the battery separates from the bottom layer of adhesive film.
If you're having trouble, apply 1-2 drops of high‑concentration (90% or more) isopropyl alcohol to the left edge of the battery. Raise the left edge of the phone to let the alcohol flow under the battery and wait one minute for it to soften the adhesive.
Lay the battery over the right edge of your phone.
Be careful not to bend the battery on the right edge of the phone frame. You may need to peel up some of the bottom layer of adhesive film by pulling the battery up before laying it over the edge of the phone.

Step 30

Peel up the remaining film from the frame.
Remove the battery.
If you used isopropyl alcohol, wait ten minutes before installing the new battery to allow the alcohol to completely evaporate.

Conclusion

To reassemble your device, follow these instructions in reverse order.

For optimal performance, calibrate your newly installed battery after reassembling your phone.
