Follow this guide to replace the charging assembly for the Pixel 3. The charging assembly contains the USB-C port as well as some antenna connectors, and is layered underneath the loudspeaker. This requires removing the loudspeaker first, which will compromise the loudspeaker’s ingress gasket.

    • Apply a suction cup to the heated bottom edge of the back cover.

    • Make sure you did not mistake the screen side for the back cover side.

    • If your back cover is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere.

    • Lift on the suction cup with strong, steady force to create a gap.

    • Depending on how aged your phone is, this may take significant force. If you are having trouble, apply more heat and try again.

    • Insert an opening pick into the gap.

    • Don't use metal tools to pry, or you'll mar or shatter the glass back cover. If the panel won't budge, apply more heat, either with a hair dryer or heat gun.

  3. Google Pixel 3 Charging Assembly Replacement: step 3, image 1 of 1
    • When inserting an opening pick above the power button, be careful not to insert the pick too deeply, or you will damage the fingerprint sensor cable.

    • Slice the adhesive along the bottom edge of the phone and around the right corner.

    • Leave a pick in the bottom edge to prevent the adhesive from re-sealing.

  5. Google Pixel 3 Charging Assembly Replacement: step 5, image 1 of 3 Google Pixel 3 Charging Assembly Replacement: step 5, image 2 of 3 Google Pixel 3 Charging Assembly Replacement: step 5, image 3 of 3
    • Heat the right edge with an iOpener and continue slicing the adhesive with an opening pick.

    • The adhesive can be very gummy. Push the pick in and out in a sawing motion to help with slicing.

    • Continue heating and slicing through the rest of the phone perimeter. Leave a pick in each edge to prevent the adhesive from resealing.

    • When slicing above the power button, do not insert the pick more than halfway in to avoid damaging the fingerprint sensor cable.

  7.

    • Once you have sliced around the perimeter of the phone, carefully lift the left edge of the back cover.

    • Do not attempt to remove the back cover. It is still attached to the phone by the fingerprint sensor cable.

    • Flip the back cover along its long axis and rest it so that the fingerprint sensor cable is not strained.

    • Remove the two 4.1 mm long Phillips screws securing the fingerprint connector bracket.

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.

    • During reassembly, be careful not to over-tighten these screws, or you may damage your display.

    • Use the point of a spudger to slide the fingerprint connector bracket out from under the NFC coil.

    • Remove the fingerprint connector bracket.

  9. Google Pixel 3 Charging Assembly Replacement, Disconnect the fingerprint connector: step 10, image 1 of 2 Google Pixel 3 Charging Assembly Replacement, Disconnect the fingerprint connector: step 10, image 2 of 2
    • Use the point of a spudger to pry up and disconnect the fingerprint connector from its socket.

    • When you disconnect connectors like these, be careful not to dislodge the small surface-mounted components surrounding the socket.

    • 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.

    • Remove the back cover.

    • Before you install a replacement back cover, be sure to remove all adhesive residue from the phone frame. Use an opening tool to scrape and high concentration isopropyl alcohol to clean the surface.

    • If you are re-using the back cover, be sure to clean off any adhesive, and apply new back cover adhesive.

    • If you are installing a replacement back cover, be sure compare it with the original part. Transfer any remaining parts (such as the flash diffuser) over to your replacement part.

is the adhesive for the back of the phone reusable, or do I need to buy a replacement adhesive for reassembly?

Campbell Wright - Responder

It depends on the age of your phone it seems - the older the phone, the less resuseable the existing adhesive. I used gasket maker to reseal my phone, in part because I did not want to heat my new battery up when trying to reseal the back cover. I would advise getting some additional adhesive if you want a water-tight assembly.

Andrew Williams -

Best to order a new back phone lid, as my back lid shattered when trying to prise it off, despite repeated heating to uncomfortably hot. Also, if you’re replacing the charging logic board because of the ‘unrecognised analogue device’ messsage, I still got the same message AFTER having put everything back together having replaced the logic board. If you shatter the back lid of the phone and have to replace it, the finger print scanner and lens covers are all prisable off and reapplicable to the new cover (with a little heating). But this requires care. Make sure to replace the battery also - because of the ka-fafel of opening this barely user-repairable phone (Cheers Google!). I ended up using gasket maker silicone (yes the stuff I use for reassembling my motorbike engine) to seal everything. Seems to have worked a treat. Good luck - you’ll need it!

Andrew Williams - Responder

I swapped out the USB-C charging port and battery at the same time. Hopefully I can get another two years out of the phone now. If you are just changing this port, then I would recommend changing the battery too. The battery replacement kit comes with new adhesive to reseal the back panel.

can I do this with a heat gun instead of the iOpener? what do I set the temperature to?
