Google Pixel 4 XL Charging Assembly Replacement
Introduction
Passez à l'étape 1This 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.

-
-
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.
-
-
-
Prepare an iOpener and apply it to the bottom edge of the back panel for one minute.
-
-
-
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.
-
-
-
Pull up on the suction cup with strong, steady force to create a gap between the back panel and the frame.
-
Insert the point of an opening pick into the gap.
-
-
-
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.
-
-
-
Prepare an iOpener and apply it on the left edge of the phone for one minute.
-
-
-
Prepare an iOpener and apply it on the right edge of the phone for one minute.
-
-
-
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.
-
-
-
Slide the third opening pick around the top right corner and across the top side of the phone, slicing the final strip of adhesive.
-
-
-
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.
-
-
-
-
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.
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.

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
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!

Using the pointed end of a spudger, pry the battery connector straight up from the motherboard to disconnect the battery.
What are the 5 copper dots under the battery connector for.
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!

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

Remove the back panel.
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.
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.

Use blunt tweezers to lift up the battery adhesive pull tabs so you can more easily grip them with your fingers.
Tabs classically broke for me, however, I rushed ahead and did not read the steps on how to remove battery with alcohol properly and ended up damaging the charging port cable. The top left-hand side of the battery is the only safe spot to insert a prying tool to remove the battery.
-
-
-
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.
-
Continue this process for each of the three pull tabs, until all are either out or have snapped in half.
-
-
-
If the battery tabs snapped during removal, insert an opening pick on the upper right edge of the battery, slicing the adhesive underneath.
Strip of glue is only on the top part, only 3 stripes. Becareful passing the gold strip
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.
Also broke this grip sensor cable but now what where to get one?
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
All three tabs broke immediately for me. Take your time with the pick, using a sawing and poking motion as described and never cross the threshold of the grip sensor cable. If you're struggling in removing the adhesive, I had great success with using the IPA dropper with high concentrate isopropyl alcohol, applying a few drops, waiting a minute, trying the pick, and repeating. Good luck, you got this.

Lift the battery up, away from the phone to remove it.
-
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.
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?
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.

-
Disconnect the vibration and bottom microphone connectors from the charging assembly.
-
-
-
Peel back the ribbon cable that's secured to the phone's frame. It's secured with some light adhesive.
-

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.
