Introduzione

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.

  1. Heat an iOpener and apply it to the bottom of the phone for one minute. When prying above the power button, be careful not to insert the pick too deeply, or you will damage the fingerprint sensor cable.

    • 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.

    The initial opening/insert is the hardest part of this repair, and if you end up having to use a flat-head screwdriver (etc) to get the first gap opened, you’ll scratch the phone. But it works.

    I don’t recommend using a screwdriver. I tried this and it shattered the glass in that area. I replaced the battery on my Pixel 1 recently and noted that heating the FRONT glass on that phone enough to get a gap for one of the pics takes a considerable amount of time AND patience. I was one of the few who didn’t break or otherwise damage the glass in that process. I would say the same rule applies here. Allow for significant time and patiences to heat the old adhesive enough to get a pick inside the cover.

    Definitely, this opening/insert is the hardest part of the procedure. I was unable to open even a slight separation with a suction cup and even with tons of heat from a hair dryer. What worked really well, and what I would highly recommend to others who experience really strong adhesive, is to use a small X-acto knife with a #16 blade. Make sure it’s a #16 (find on Amazon) because it differs greatly in angle and rigidity from the usual #11 blade. The sharpness of the blade makes it really easy to find the crack and open a gap, where you can then insert a pick with no problem.

    Andris Vizulis - Replica

    I gave up with the iOpener and pick, I tried >5 times for over an hour… After heating with theiOpener, I used and X-acto knife instead and that worked like a charm, except it did leave a few scuff marks unfortunatly. I used a size 22 blade.

    I really wanted to level off the back of the phone when pulling on the suction cup in this step, but found it was actually pretty easy once I used the opening tool to push down on the edge of the bezel, at the crack, barely putting any force on the back of the phone at all (just to keep it steady).

    Eugene Creswick - Replica

    I have about a 2 year old Pixel 3. iOpener didn’t work at all on this step, but once I broke out the hair dryer, I was able to get the phone hot enough to insert the pick (no screwdriver or xacto knife needed)

    sliverdragon37 - Replica

    I’m having trouble with the iOpener too. It is frustrating because I practiced on a bricked iPhone earlier this week and it was effortless. My Pixel 3 is also about 2 years old. Out of curiosity, were you replacing the charging assembly because of the charging cables fitting too loosely on the phone or for some other reason?

    Edwin -

    I used a stanley knive to get started and then a combo of opener and plektrums.

    All went well till I used to much force on the camera corner and broke the back into lots of small pieces. Be careful on that corner, people.

    But the new camera does focus, so for a first attempt at fixing a phone I am happy.

    clas ebeling - Replica

    I heated the bottom up with the Iopener and then used a rectangular razor blade and the suction cup to lift the bottom. Place the entire blade edge into the crack and push/pry while lifting with the suction cup. As soon as you have a gap start to open, have a second person insert a pick into the corner. It was actually really easy. I had given up after a couple of tries without a blade. My Pixel 3 is 2 years old.

    Jeremy Stewart - Replica

    Agreed with many other comments here. My Pixel 3 is two years old and neither the iopener nor a blow dryer were capable of loosening it enough. I ended up using a VERY hot iopener for a couple of minutes, the suction cup, and then a wide-bladed razer blade (about 80% width of bottom edge to spread out the stress and prevent risk of fracturing the rear glass panel). Once adding the razer blade I was able to get the pick in and follow the rest of the instructions as written.

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

    • Remove the fingerprint connector bracket.

    Re-inserting this is tricky and requires pretty good dexterity. The shiny metal frame of the wireless charger is also not held down, so you may wish to gently apply pressure to it as you try to re-position the connector bracket.

    • 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 new adhesive required to reassemble, or is it reuseable?

    Campbell Wright - Replica

    Hi Campbell,

    If the adhesive is in decent condition, you can try to re-use the adhesive. Squeeze the back cover along the perimeter, and heat it with a hair dryer to help the adhesive re-bond. Note that there is a chance that the back cover may fall off when you reuse the adhesive.

    Arthur Shi -

    When reassembling is it better to first attach the new adhesive back gasket to the phone back or the phone chassis frame?

    Tom Burke - Replica

    Hi Tom!

    It depends on the adhesive. Carefully align the adhesive to the phone by matching the contours. Note which adhesive side is backed by a clear liner, and which side is backed by a colored liner. The clear liner should be removed first. Whichever component the exposed adhesive faces should be the first surface to apply to.

    Hope that helps!

    Arthur Shi -

    Two things:

    1) I recommend attaching the adhesive to the Phone frame and not the back panel. As you attach, you can more easily see the gaps and guide the adhesive along the groove, leaving equal space all around.

    2) To transfer the fingerprint sensor, you will need double-sticky tape to make a new gasket. Put the tape on the back from the inside, and trim with a blade to make the sensor hole. To attach the sensor, place it on something small to raise it off your working surface, then lower the back over it. You’ll be able to see the sensor alignment as you lower the back, which helps get a good position.

    Oh, and be prepared: Removing the old adhesive is teeeeedious!! It will take you some time. :-b Alcohol is not a strong solvent, so don’t expect it to remove much; it is mostly for cleaning afterward. In the end, I used one of iFixit’s flat metal tools from the big toolkit to remove the final remains. Its was blunt enough to not cut metal shavings as I cleaned.

    Gary Beardsley - Replica

    I ended up reusing the original adhesive as it was in pretty good shape. So far, no problems.

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

Campbell Wright - Replica

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!
