How to replace Samsung Galaxy Note 9 wireless charger pad

If your Samsung Galaxy Note 9 doesn’t charge wirelessly but charges fine with wired charger, then the problem could be with its wireless charger pad, which is located on top of the battery when the phone is facing down. In other words, it’s on the back side of the device and that’s the reason why you place the phone facing up when you want it to charge wirelessly.

When it gets damaged, only the wireless charging capability is affected. Your Note 9 may still fast-charge using the wired charger and you can still use it normally. Spare parts for the Note 9 can now be bought online and for this specific module, if I’m not mistaken, it costs $6.00 more or less. That’s right, the wireless charger pad inside your phone is actually cheap but the tech may still want you to pay around $50 to $75 for the service fee.

So, you will really have a great advantage if you knew how to dissect your Note 9 successfully because the moment you’ve removed the back cover, replacing inside components would be a lot easier. I understand that if you want to take pictures underwater, the device’s IP68 is very important but if you’re not that kind of a user, then you can still leave with a Note 9 that’s not water-resistant anymore. I’m saying this because aside from the wireless charger pad, you may also have to buy the adhesive that you’ll use to make your phone water-resistant but if that doesn’t matter to you, you can replace the back cover without those new sets of adhesive.

Now, let’s go back to replacing the wireless charger pad inside your phone and here’s what you need to do…

Things you need

  • Suction cup
  • Small Phillips screwdriver
  • Prying tools
  • Heat gun or hair dryer
  • OEM Wireless Charger for Samsung Galaxy Note 9

Remove the back cover

  1. Remove the SIM/SD card tray and pull the stylus out.
  2. Using the heat gun, heat up the edges of the back cover until it would be uncomfortable to touch it. Just apply enough heat to loosen the adhesive and remember that applying too much heat may damage the battery. And when applying heat, do not point the gun in one place, always move around the edges.
  3. Once the cover is hot enough, put the suction cup on the lower part of the phone or where the USB port is.
  4. Gently lift the suction cup until you can see a slight opening between the back cover and the frame. After applying reasonable amount of upwards pressure, the back cover should separate slightly from the frame but if it doesn’t, you may need to apply more heat.
  5. Place a prying tool into the crack to prevent the glue from sticking back to the frame.
  6. Once the prying tool is inserted, you may now remove the suction cup.
  7. Move the prying tool along the sides to loosen the adhesive but be very gentle in doing this so as not to mess up some components. Also, don’t push the prying tool too deep. You may use more prying tools if necessary. If the phone cools down before the back cover is removed, try applying heat again to loosen up the adhesives.
  8. Once the back cover is loose enough, lift it gently so as not to break the flex cable of the fingerprint scanner. Remove the flex cable to set the back cover free.

Removing the back cover takes too much time, I know but you can never skip this step because it’s the primary protection of the phone. Note 9 is a notch-free device and that means that its components are either screwed to the frame or glued together…carefully.

Remove defective wireless charger pad

The charger pad is a part of the top frame that secures smaller components inside and it’s secured by 11 screws. It covers the top part of the phone and the battery but don’t worry, it’s a lot easier to remove it…

  1. Remove the screws one by one.
  2. Once all screws securing it are removed, you can easily remove the wireless charger pad with your fingers.
  3. Now, place a new charger pad and secure it with the screws.

Replacing the back cover

As I said earlier, if you’re not so particular with the IP68 certification of the Note 9 that makes is dust- and water-resistant, then you can simply use the old (possibly damaged) adhesive on the back cover. If you still want your phone to be water-resistant, you should buy the OEM Back Cover Sticker for Samsung Galaxy Note 9. To replace the back cover, here’s what you need to do…

  1. If you don’t have the back cover adhesive, then reconnect the fingerprint sensor flex cable to the connector.
  2. If you have a new set of adhesive, then remove the old adhesive from the back cover and install the new one.
  3. Carefully place the back cover in place and then hit it with a heat gun and gently press it in place until it cools down.

Depending on how good the back cover is replaced, your phone may still be water-resistant after this. Also, the back cover sticker costs around a dollar or two so I suggest you buy one together with the component you want replaced before you actually open your phone.

I hope that this guide can help you one way or another. Thanks for reading.
