Google Pixel 4 XL Wireless Charging Coil Replacement

Difficulty

Moderate

Steps

Time Required

10 - 30 minutes

Introduction

This repair guide was authored by the iFixit staff and hasn’t been endorsed by Google. Learn more about our repair guides here.

Use this guide to remove or replace the wireless charging coil on your Google Pixel 4 XL.

Caution: The wireless charging coil is adhered to the back panel as a large sticker. It is covered by an insulating / heat-dissipating graphite adhesive layer which will need to be destructively removed and will need to be replaced.

Caution: Google warns that disassembly of the front laser assembly could result in hazardous exposure to invisible infrared laser emissions. Read their safety warnings here.

Tools

Step 1

Insert a SIM eject tool, bit, or a straightened paper clip into the small hole on the SIM card tray on the left edge of the phone.
Press firmly to eject the tray.
Remove the SIM card tray.

Step 2

Prepare an iOpener and apply it to the bottom edge of the back panel for one minute.
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 both susceptible to heat damage.

I found 2 minutes works best per side. Great Guide btw, thank you for being a strong leader in the fight for right to repair.

Step 3

Apply a suction cup to the heated edge of the back panel by pressing down on it to create suction, as close to the edge as possible.
If your back glass is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken panel.

Step 4

Pull up on the suction cup with strong, steady force to create a gap between the back panel and the frame.
Depending on the age of your phone, this may be difficult. If you are having trouble, apply more heat to the edge and try again.
Insert the point of an opening pick into the gap.

Step 5

Slide the opening pick across the bottom towards the left corner to slice the adhesive.
With the pick still inserted, slide it from the bottom left corner over to the bottom right corner to completely slice the bottom side adhesive.
Leave the pick inserted in the bottom right corner to prevent the adhesive from re-sealing.

Step 6

Prepare an iOpener and apply it on the left edge of the phone for one minute.

Step 7

Insert a second opening pick underneath the back panel directly over the charge port.
Slide the opening pick to the bottom left corner of the phone.

Step 8

Slide the opening pick around the bottom left corner and across the left side of the phone to slice the adhesive.
The adhesive can be very gummy. Push the pick in and out in a sawing motion to help with slicing.
Stop when you reach the top left corner, near the camera, and leave the pick inserted.

Step 9

Prepare an iOpener and apply it on the right edge of the phone for one minute.

Step 10

With the first two opening picks still in place, insert a third pick on the lower part of the righthand side.
Slide the opening pick up towards the top of the phone, slicing the right side's adhesive.
Stop when you reach the top right corner, and leave the pick inserted.

Be careful when slicing the right side's adhesive. The contacts for the wireless charging pad are close to the edge and can easily be bent with the opening pick.

Step 11

Slide the third opening pick around the top right corner and across the top side of the phone, slicing the final strip of adhesive.

Step 12

Once you have sliced around the perimeter of the phone, carefully lift the right edge of the back cover, opening it like a book.
Do not try to pull the panel all the way off yet, as it is still connected to the phone.

Step 13

Continue swinging open the back panel until you can rest it on the left edge the phone, being careful not to put any stress on the attached ribbon cable.
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.

“and test all functions before sealing it up.”

Pretty sure I wont be sealing this up for a few hours, might be worth removing this part of the sentence as it’s confusing…

Geoff B: These are good instructions. Any technician worth his or her salt will test the device for functionality before sealing it up. That’s why it reads, “During reassembly…and test all functions before sealing it up.” Not confusing if you read and comprehend the full pin.

No instructions on how to fit new sticky gasket before assembly. Removing old adhesive was a messy business, I used IPA on a cotton bud and removed as much as possible with flat end of spudger and kitchen paper.

Step 14

Remove the four T3 Torx screws securing the battery connector shield:
One 1.8 mm screw
One 4.1 mm screw
One 4.4 mm shouldered screw
One 4.0 mm shouldered screw
Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.

Anyone know the thread size of the 1.8mm screw mentioned here? Mine went missing, and I need to get a replacement. I've got a bunch of tiny screw kits, but none of them have fit!

Step 15

Use a pair of tweezers to remove the battery connector shield.

Step 16

Whenever you use the spudger near the battery, be very careful not to puncture the battery.
Using the pointed end of a spudger, pry the battery connector straight up from the motherboard to disconnect the battery.
To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.

I had the piece from the cable break off inside the connector. How would I go about getting it out

Dylan DVP -

What are the 5 copper dots under the battery connector for.

Brian Davis -

When you reattach the connector to the motherboard this is a good time to power up and check basic functionality temporarily. Even though it had appeared it was correctly lined, my camera was not functional, in particular the switch button from the rear to the front camera, I was stuck in selfie mode. Then I was getting a message on the screen, possible hardware or software issues. Once I reattached the connecter (several times) until it was correctly inlined, the error went away and I was able to switch from the rear and front cameras.

That was a good call! Thanks!

Step 17

Using the flat end of a spudger, gently fold the battery cable over so it doesn't accidentally make contact during the rest of your repairs.

Step 18

Use a T3 Torx driver to remove the two 4.1 mm screws securing the back panel connector cover.

Wouldn’t it make more sense to use the same (orange) color circles as the other 4.1mm screw?

Maybe Google did it to avoid exchange in the models where they differ

Step 19

Use a pair of tweezers to remove the back panel connector cover.

Step 20

Using the pointed end of a spudger, pry up and disconnect the back panel connector.

During reassembly, make sure to firmly connect this back panel connector.

I had to hold the back panel close to the phone so that the connector stays connected, while putting back all the screws.

Step 21

Remove the back panel.
During reassembly, follow this guide to install custom-cut adhesives for your device.
Follow this guide if you are using a pre-cut adhesive card.

REASSEMBLY ADHESIVE: This is the step during reassembly that you'll want to set the back glass adhesive strip on (before you reattach ribbons). Set the adhesive strip into the body of the phone with the red tabs down (toward the body of the phone, it will simply rest inside the lip of the phone body). Press the back glass onto the adhesive strip to set the strip onto the back glass, lift the back glass back out of the body of the phone. Next reattach the ribbons, test functions, reattach connector covers, peel red adhesive cover off of the adhesive (on the back glass) then set the back glass into the phone lip. This could have been explained far better but was skipped over and the generic adhesive instructions posted in the comments are useless for this.

There are also detailed instructions at answer 742532, "How do I apply new back panel adhesive on a Pixel 4xl?" (sorry it doesn't let me link directly). But it advises adhering the adhesive to the main frame first before the glass. I do notice a slight lip on the main frame on both sides, which seems less forgiving to align with than the glass, so I would imagine doing the frame first would be easier? I haven't done this yet myself, so would be interested in opinions.

AySz88 -

Update: it appears the discrepancy is due to a difference between the third-party adhesives and the iFixit "genuine" one. The iFixit one is not mirror symmetric and must be adhered to the glass back first, though it has cutouts that avoid protrusions and facilitate this. The third-party one (I believe) has no such cutouts and thus must go on the frame first.

However, in trying to follow Michael's instructions, I could not get the adhesive and red tabs off the blue plastic without distorting the adhesive, and had to take the clear side off first. I ended up directly placing the adhesive onto the glass back, without the frame to help align (I posted my method in the above-mentioned answer 742532). The cutouts in the blue plastic seem to have been made with this in mind.

Step 22

The wireless charging coil adhered to the back panel is covered by a graphite adhesive layer which will need to be removed.
Use tweezers on one of the bottom corners to pull up the adhesive enough to grab it with your fingers.

Step 23

Peel back the graphite adhesive layer to expose the wireless charging coil and NFC pads.
Completely remove the graphite adhesive layer.

Step 24

Use tweezers on one of the bottom corners of the wireless charging coil pad to pull up the adhesive backing enough so you can grab it with your fingers.
Peel off and remove the wireless charging coil.
When installing a new wireless charging coil pad, align the contacts with the residue outline left by the old adhesive.

you will have to find the wireless coil yourself as ifixit does not carry this unit.

Conclusion

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow the above steps in reverse order.

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