Introduction

The charging port in the connection point where the charging cable goes in to feed power to the device. You may want to check our troubleshooting page first to verify that there isn't a problem with the software of the device.

If the problem turns out to be a hard ware problem, then you will have to replace the charging port board on your device.

Be forewarned- replacing this part involves breaking your phone's waterproof seal. If you want your phone to keep its waterproof capabilities, you will have to replace the seal.

  1. Before you begin, switch off your phone.
    • Before you begin, switch off your phone.

    • Apply a heated iOpener to a long edge of the phone to loosen the adhesive beneath the rear glass. Apply the iOpener for at least two minutes.

    • You might need to reheat and reapply the iOpener several times during the removal procedure to get the adhesive warm enough to cut. Follow the iOpener instructions to avoid overheating.

    • The adhesive of the Samsung Galaxy S9 is very strong. A hair dryer, heat gun, or hot plate may also be used if you aren't able to open the device with the iOpener. Be careful not to overheat the phone—the AMOLED display and internal battery are both susceptible to heat damage.

    Nightmare. Impossible to get the back off so far. Being trying using the iOpener with hair dryer for last 1hr. No chance.

    You’re right Chris. I’ve tried on 3 separate occasions now and haven’t been able to budge that back. All that has happened is the pick has taken a piece out of the glass back leaving a rough edge now.

    it was not easy but doable.

    It’s difficult, but the trick I did to get it was to wrap the hot iOpener around a bottom corner, apply the suction cup, then I covered the opener and phone with a paper plate, better insulating the area. Then I set my blow dryer to high heat and low velocity and heated the area under the plate for about a minute. Right after turning off the blower, I took off the plate and pulled the suction cup with a cutter at hand. You’ll hear a bit of a cracking/popping noise when the adhesive is starting to give, just apply a little more force and push the cutter at the seam. This method worked great for me, so good luck and just keep at it — you’ve got this!

    I used nearly boiling water in a storage zip bag on the phone for 10 minutes. I can’t really recommend this method, but thankfully the bag did not leak - an iOpener is probably a much better way to go. Regardless, the bag covered the entire back of the phone, and the phone was too hot to hold, but I still could not get the glass to budge with the suction cup after struggling with it for about an hour and multiple reheats. I ended up epoxying a 2”x2” square of PVC board to the bottom of the cover and built a relatively complex fixture that pulled on the PVC with the turn of a screw while it held down the frame by the edges. After heating the edges up again It did lift the glass enough to get a pick underneath it, but it cracked the glass and it was a pain to slide a pick around the edge while the glass was cracking all the way around. Once I finally got all the glass off, I spent the next 30 minutes (which is what this entire process is supposed to take… what a joke!) cleaning the adhesive off the phone.

  2. In the following steps, you'll be cutting through the adhesive securing the back cover.
    • In the following steps, you'll be cutting through the adhesive securing the back cover.

    • The adhesive in the inside of the back cover is laid out as seen in the image.

    • You'll be slicing through the adhesive in the areas shown:

    • Thick portions of adhesive

    • Thin areas of adhesive

    • Avoid prying or slicing in this area, to protect the fingerprint sensor flex cable.

  3. If the phone's rear glass is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed. Press a suction cup onto the back cover. Lift the back cover's bottom edge with your suction cup, opening a slight gap between the back cover and the frame.
    • If the phone's rear glass is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.

    • Press a suction cup onto the back cover.

    • Lift the back cover's bottom edge with your suction cup, opening a slight gap between the back cover and the frame.

    • This may require a significant amount of force, but you only need to open a very slight gap with the suction cup to insert your tool. If you have trouble, apply more heat to further soften the adhesive, and try again. The adhesive cools very fast, so you may need to heat it repeatedly.

    • Insert an opening pick in the gap you created and slide it to the bottom right corner.

    • Insert a second opening pick and slide it to the bottom left corner.

    • Insert a third opening pick to prevent the adhesive from resealing during the rest of the removal procedure.

  4. While inserting only the tip of the opening pick, slide it from the bottom left corner along the side to the top. Slide the pick around the top corner and leave it there to prevent the adhesive from resealing.
    • While inserting only the tip of the opening pick, slide it from the bottom left corner along the side to the top.

    • Slide the pick around the top corner and leave it there to prevent the adhesive from resealing.

  5. Slide the opening pick from the bottom right corner along the side to the top. Apply more heat if the adhesive becomes hard to cut. During the removal process, the back cover is under tension all the time and is likely to break if the adhesive isn't softened enough. Slide the opening pick around the corner and cut the remaining adhesive at the top of the phone.
    • Slide the opening pick from the bottom right corner along the side to the top.

    • Apply more heat if the adhesive becomes hard to cut. During the removal process, the back cover is under tension all the time and is likely to break if the adhesive isn't softened enough.

    • Slide the opening pick around the corner and cut the remaining adhesive at the top of the phone.

    • Don't open the phone all the way yet. The fragile fingerprint sensor cable still connects the back cover to the motherboard.

  6. Carefully lift the side of the rear glass where the volume button is located. Use the edge of a spudger to pry up and disconnect the fingerprint sensor flex cable.

  7. Remove the rear glass.
    • Remove the rear glass.

    • When reassembling follow this guide to replace the adhesive and reinstall the rear glass.

    • In case you want to replace your rear glass follow this guide to transfer the rear camera bezel including the fingerprint.

  9. Remove the NFC coil assembly.
    • Remove the NFC coil assembly.

    This is not quite as easy as the simple statement “Remove the NFC coil assembly” would lead you to believe. The top and left side of the plastic bracket attached to the coil have tabs inserted into the frame of the phone and you can’t just pick the coil assembly up. It takes a bit of force, and I used a spudger to gently pry along the top from right to left to pop the tabs free, and then the tabs on the left came out more easily. Do not just pull on the coil and bend it up.

  10. Remove the motherboard bracket.
    • Remove the motherboard bracket.

    My phone did not have a separate bracket covering the motherboard.

    jason boesiger - Réponse

    The NFC/wireless charging coil is adhered to the motherboard bracket, and in my case they both came off together.

    Also, for safety, the battery connecter should be disconnected in this step rather than waiting until after removing the speaker cover/antenna assembly.

    Hi Kara! If I remember correctly, we didn’t need to remove the battery. However, it’s been over a year, so I could definitely be wrong.

    • Disconnect three cables.

    • If your replacement charging port does not come with the blue and white cables, you will need to remove them from your old board in order to connect your new one.

    Forgot step to remove logic board held by several connectors and one screw. Connect new charging port cable to mother board before putting it back together.

    Kara Monster - Réponse

    Could you point out to me where the logic board is? It’s possible we called it something else.

    Ani Svadjian -

    The board to the left of the battery the two cables connect to.

    Spencer Buskirk - Réponse

    Kind of a big step to miss.

    Spencer Buskirk -

    Oh, I think I get what y’all are pointing out.

    1) We called the logic board the charging port board.

    2) We did disconnect the two cables (the blue and white ones, right?) in the step above, as seen by the upper red rectangle. (Look at step #13)

    3) I’m having trouble finding which screw we missed. Could you identify it a little better so I can fix the picture? (Look at step #12)

    Ani Svadjian - Réponse

    We might also have called the logic board the mother board, which you do not need to remove as long as you detach all of the cables.

    Ani Svadjian -

    Yes, logic board must be removed. It is what you called the motherboard. We had to remove the motherboard enough to be able to mate the charging port board to the motherboard multipin connection seen under the index finger in the photo for step 15.

    jason boesiger - Réponse

    I’m not sure if I can change the prerequisite guides now that this one has been published, but we do have a motherboard replacement guide here. It has detailed instructions on removing the motherboard/logic board.

    Ani Svadjian -

    We also had to remove the opposite ends of the blue and white cables from the charging port board since our replacement charging port board did not come with new cables.

    jason boesiger - Réponse

    Thanks! I’ll see if I can add that in.

Hi, does the screen need to be replaced once the charging port has been replaced?

Elliot Lawrence - Réponse

Hi Elliot! If you replace your charging port, you will need to replace the back cover, but the screen should remain intact. It is very difficult to remove the back cover without breaking it (unless you have access to a heat gun), so if you’re thinking about replacing your charging port, you may want to get a new back cover ready beforehand. Good luck and Happy Fixing!

Ani Svadjian -

A lot of parts missing to this guide.

Kara Monster - Réponse

Hi there, is there anything you would recommending replacing/updating/upgrading while you have the phone disassembled? Thanks!

Callum Eve - Réponse

This guide is decent, but it was not my primary reference for this task. IMO a better guide can be found here: https://www.youtube.com/watch?v=o1NYvdkZ...

**VERY IMPORTANT!**

You have to buy the same revision charging board as the one that’s in your phone, the one that i unknowingly ordered was a E4 but my phone needed a C7. Now i’m hunting down the correct parts and my phones not working.
