Introduzione

Use this guide to remove or replace a worn battery in the Google Pixel 4. If your battery is swollen, take appropriate precautions.

For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

Note: Some photos in this guide show the SIM card tray ejected from the phone. You do not need to eject the SIM card tray for this procedure.

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.

  1. Prepare an iOpener and apply it to the bottom edge of the back panel for one minute.
    • 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.

  2. 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.

  3. 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.

  4. 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.

    • Slide the opening pick to the bottom left corner of the phone.

  7. 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.

  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. Do not try to pull the panel all the way off yet, as it is still connected to the phone.

  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.

    • Remove the five T3 Torx screws securing the battery connector shield:

    • Four 4.0 mm screws

    • One 2.1 mm screw

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

    • 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.

  16. 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. 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.

  20. Remove the back panel.
    • Remove the back panel.

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

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

    • If you are installing a replacement back panel, be sure compare it with the original part.

  21. Pull on the yellow pull tab at a shallow angle with steady force. If the adhesive becomes hard to pull, you can roll it around a spudger and continue pulling. Continue firmly pulling up on the adhesive strip with constant force. If you're using a spudger, spin it 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. Pull 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.

  22. 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.

    • 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.

  23. Lift the battery up and away from the phone to remove it. You may need to peel the battery away from any leftover adhesive tabs.
    • Lift the battery up and away from the phone to remove it.

    • You may need to peel the battery away from any leftover adhesive tabs.

    • To install a replacement battery:

    • Lay some double-sided tape 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 on the adhesive and press firmly.

    • Disconnect the battery connector from its motherboard socket and resume re-assembly.
