Introduction

Follow this guide to replace a dead or worn-out battery in your Samsung Galaxy S23.

This guide is for the battery itself. If you're replacing the screen and battery assembly (the frame, screen, and battery as one piece), follow this guide.

Your phone's lithium-ion battery has a limited lifespan. If your phone dies quickly and doesn't hold a charge, it may be time to replace the battery.

If your battery is swollen, take appropriate precautions.

Note: 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.

Tools

Parts

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 to soften the adhesive.
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.

When inserting the first pick, I partly cracked my backplate: if the opening is not long enough, inserting the pick puts vertical pressure on the backplate and it'll crack. I suggest slicing a few centimeters of glue before inserting the pick.

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

Insert a second opening pick at the bottom right corner.
Rotate it around the bottom right corner to separate the adhesive.

Step 7

Slide your 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 your pick toward the top left corner to separate the adhesive.
Leave the pick in the top left corner to prevent the adhesive from resealing.

Step 11

Heat an iOpener and apply it to the top edge of the back cover for two minutes.

Step 12

Insert a fourth opening pick at the top left corner.
Rotate it around the top left corner to separate the adhesive.

Step 13

Slide your opening pick to the top right corner to separate the adhesive.
Leave the pick in the top right corner to prevent the adhesive from resealing.

Step 14

There's a remaining patch of adhesive directly under the flash.
Line up the tip of an opening pick with the flash cutout.
Slide the opening pick under the top of the back cover until you feel it start to snag on the adhesive.
You should see the opening pick through the flash cutout.
Keep sliding the pick toward the bottom of the phone until you feel the adhesive completely separate from the back cover.
Avoid touching the rear cameras with your pick. Pushing against the lenses risks damaging them.

Step 15

Grab and remove the back cover.
If your cover is still sticking to the frame, slide an opening pick around the perimeter until the cover completely separates.
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.
Remove any adhesive chunks with a pair of tweezers or your fingers. Apply heat and isopropyl alcohol (90% or greater) if you're having trouble removing the adhesive.
If you're using custom-cut adhesives, follow this guide.
If you're using double-sided tape, follow this guide.

Just before removing the backplate, take care at the long ribbon cable (in white on the 2nd and 3rd photos, next to the black wireless charging patch). In my case, part of it was gently glued to the backplate for some reason, so double-check that you've separated it from the backplate before attempting to open it, or you might just rip the ribbon cable entirely. In my case, this was preventing me lifting the backplate for more than a few millimeters, and I'm glad I didn't force it before trying to understand exactly what was going on.

Step 16

Use the point of your spudger to pry up and disconnect the wireless charging coil press connector from the motherboard.
To re-attach press connectors, carefully align and press down on one side until it clicks into place, then repeat on the other side. Don't press down on the middle. If the connector is misaligned, the pins can bend and cause permanent damage.

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 your spudger in the notch at the top left corner of the loudspeaker.
Pry up to unclip the loudspeaker from the frame.

Step 19

Use your fingers to lift the loudspeaker away from the frame to fully separate it.
Remove the wireless charging coil and loudspeaker from the frame.
During reassembly, press around the perimeter of the loudspeaker to clip it to the frame.

Step 20

Use the point of your spudger to pry up and disconnect the battery press connector.

Step 21

Use your spudger to pry up and disconnect the primary and secondary interconnect cable press connectors from the daughterboard.

Step 22

Repeat the previous step for the primary and secondary interconnect cable connectors on the motherboard.

Step 23

Remove both interconnect cables.

Step 24

Use your spudger to pry up and disconnect the display and 5G mmWave cable press connectors from the motherboard.

Step 25

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

Step 26

Use your finger to push the battery and antenna cables away from 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.
Use your fingers to carefully peel the battery pull tab from the left side of the battery.

Step 28

Peel the two small tabs from the top and bottom corners of the battery's left edge.
If these tabs aren't fully separated, you won't be able to lift the battery in the next step.

Step 29

With one hand, fold the two upper and lower tabs out of the way of the battery and firmly hold down the frame.
If you're having trouble with the tabs, you can fold them under the phone and tape them to the screen.
With your free hand, grip the blue center pull tab and pull straight up with strong, steady force to separate the battery adhesive.
The adhesive might not separate immediately. Keep pulling with consistent force until the battery comes free from the frame.
If you're having trouble, apply 1-2 drops of high-concentration (more than 90%) isopropyl alcohol to the left edge of the battery. Elevate the left edge of your phone and wait one minute for the alcohol to soften the adhesive.
Lay the battery over the right edge of your phone.

Step 30

Peel the battery's plastic film from the frame.
Remove the battery and its film.
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.

Take your e-waste to an R2 or e-Stewards certified recycler.

Thank you for this guide! Easy to follow. I couldn't get the phone open until I bought the iopener kit and anticlamp. Once I got it open, wasn't a big deal to replace. I did take photos that helped as I was opening it, as my battery was slightly different from these photos and I wanted to make sure I knew exactly what I was looking at. It works great now and turned right back on with no issue. Thank you!

Thank you very much for this guide. My phone basically bricked after an update, and there was nothing I could do to make it respond. Holding the power and volume buttons, charging it, even plugging it into my computer gave zero feedback (totally black screen, no vibration or sound). I had to pop the phone open and completely disconnect the battery, and when I reconnected it everything was back to normal. It was my first time ever disassembling and attempting to repair electronics and this guide was essential in figuring out what I was doing.
