Steps

Time Required

30 minutes - 2 hours

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 charging assembly on your Google Pixel 4 XL. The charging assembly contains the USB-C port, as well as some antenna connectors, and is layered underneath the loudspeaker and battery.

This process requires removing the loudspeaker, which will compromise the loudspeaker’s ingress gasket.

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.

Warning: Do not reuse the battery if it has been deformed or damaged, as doing so is a potential safety hazard. Replace it with a new battery.

Google Pixel 4 XL Charging Assembly - Genuine

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.

John G -

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 - 03/05/21

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.

Jeana Morales - 02/06/21

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.

Malcolm Hall -

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!

Joseph Sctbunio -

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.

bonita pauley -

That was a good call! Thanks!

Esther -

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?

Mark Kanzler - 18/05/21

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

Daniele Carminati - 18/05/21

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.

Esther -

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.

Michael A. Mascaro -

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.

AySz88 - 26/11/22

Step 22

Use blunt tweezers to lift up the battery adhesive pull tabs so you can more easily grip them with your fingers.
The battery is held in place with three separate stretch adhesive strips, which are connected to a single black pull tab. You can try to pull all three strips out together, but it is easier to cut the black pull tab where it is notched and pull each strip out individually.

Yellow tab instead of black in my oh so orange Pixel 4XL

Geoff B - 03/05/21

Step 23

Pull on the black pull tab at a shallow angle with steady force. When the adhesive grows long, roll it around a spudger and continue pulling.
Continue firmly pulling up on the adhesive strip with constant force, spinning the spudger every so often to keep the exposed section of the pull tab as short as possible.
This may take a lot of force.
These adhesive pull tabs are very prone to snapping in half during this process. Try pulling as slowly as possible.
If the adhesive pull tabs are not stretching, you can fill a plastic dropper or syringe with high concentration isopropyl alcohol and apply a few drops under the left edge of the battery. Give the alcohol a minute to weaken the battery adhesive.
Continue this process for each of the three pull tabs, until all are either out or have snapped in half.

Step 24

If the battery tabs snapped during removal, insert an opening pick on the upper right edge of the battery, slicing the adhesive underneath.
Even if you successfully removed all three adhesive pull tabs, using an opening pick to dislodge the battery may be helpful.
Don't insert the opening pick on or anywhere below the grip sensor cable, as the pick can damage the charge port flex cable located underneath the battery.

Strip of glue is only on the top part, only 3 stripes. Becareful passing the gold strip

Jairon Lopez - 06/03/21

I wouldn't risk going across the topside of the battery either. the thin cable connecting the side buttons to the board is exposed and is easy to break. Learned from experience.

Rancid -

Also broke this grip sensor cable but now what where to get one?

David Johnson -

I carefully pulled up the battery from the bottom using the opening pick because my adhesive pull tabs snapped. The battery was so strongly glued to the bottom. I needed to use the other tools in the box to really push the battery out. Could not do it that gently. But anyway succeeded! v

Esther -

Step 25

Don't reuse the battery if it has been deformed or damaged, as doing so is a potential safety hazard. Replace it with a new battery.
Lift the battery up, away from the phone to remove it.
To install a replacement battery:
Remove any remaining adhesive from the battery well.
If you're using stretch release adhesive, apply them onto the battery. Otherwise, apply some double-sided tape, or pre-cut adhesive strips in the phone's battery well, being careful not to cover the charge port flex cable. Peel away any tape liners to expose the adhesive.
Temporarily re-connect the battery's connector to the motherboard socket. This ensures that the battery is properly positioned.
Lay the battery in place and press firmly.
Disconnect the battery connector from its motherboard socket and resume re-assembly.

The kit comes with a replacement glue strip for the back cover. I would like to have seen some guidance on putting that on. I’m not exactly a beginner at repairing things in general, but this is the first time I’ve worked on a phone. Figuring it out wasn’t too bad, but getting the old glue off enough to make it work added 15-30 minutes to the process.

Jason Ridenour - 18/11/20

This is what I’m sitting at now. probably 90% of the original glue off. did you put the replacement strip on the cover first or the body of the phone?

david janzen - 10/12/20

For this, I peeled off the white strip and placed the new adhesive (with blue template still on) onto the inside of the back cover, making sure it aligned. I then peeled off the blue sheet and applied pressure and a mostly-cooled iOpener to help it adhere. Worked very well for me.

Zaeda June - 25/01/21

You can follow this adhesive guide for installing new battery adhesive!

Carsten Frauenheim - 26/01/21

I decided to give up on getting all of the original adhesive stuff. I removed maybe 30% of it and then placed the replacement strip. It seems to be okay, and the back closed all the way.

Chem -

FYI the kit includes a new adhesive tapes for the battery. I only found out because I looked inside the kit.

Esther -

Step 26

Remove the three T3 Torx screws securing the loudspeaker:
One 4.1 mm screw
One 2.7 mm screw
One 4.4 mm shouldered screw

On my model there is only two screws holding the speaker and it slides forward (towards the battery compartment) to release.

Joe -

Step 27

Use a pair of tweezers to remove the loudspeaker.
Before you install a replacement loudspeaker, check the adhesive gasket:
If it is in good condition, you can re-use the gasket. Make sure that the gasket does not cover the exit hole.
If the gasket is pulled out of place, remove it and replace the adhesive with a pre-cut strip or Tesa tape.

Step 28

Use a T3 Torx driver to remove the four 3.5 mm screws securing the display connector cover.

Step 29

Use a pair of tweezer to remove the display connector cover.

Step 30

Using the pointed end of a spudger, disconnect the charging cable connector by prying it straight up from the motherboard.

Step 31

Disconnect the antenna press connector from the charging assembly.

Step 32

Disconnect the vibration and bottom microphone connectors from the charging assembly.

Argh... don't miss the microphone like I just did!

Jon Barlow -

Step 33

Use the pointed end of a spudger to pry up and disconnect the black antenna cable from its socket on the motherboard.

Step 34

Peel back the ribbon cable that's secured to the phone's frame. It's secured with some light adhesive.

Step 35

Remove the charging assembly.

For reinstallation, I found it best to connect the port, then the vibration/microphone connections, then the charging cable connecter, with a sharp bend made in the connector, then remove the blue adhesive coatings and flatten/adhere the cable.

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.
