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.

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

Step 7

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 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.

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 the point of a spudger to pry up and disconnect the NFC antenna press connector.

Step 18

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 19

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 20

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 21

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

Step 22

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

Step 23

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

Step 24

Remove the interconnect cables.

Step 25

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

Step 26

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 27

Use your finger to push the battery and antenna cables away from the battery.

Step 28

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 from the left side of the battery.

Step 29

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 30

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 31

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.
