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 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. Google Pixel 4 Battery Replacement, Heat the back panel glass: adım 1, 1 resimden 1.
    • 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. Google Pixel 4 Battery Replacement, Apply a suction cup: adım 2, 2 resimden 1. Google Pixel 4 Battery Replacement, Apply a suction cup: adım 2, 2 resimden 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. Google Pixel 4 Battery Replacement, Insert an opening pick: adım 3, 2 resimden 1. Google Pixel 4 Battery Replacement, Insert an opening pick: adım 3, 2 resimden 2.
    • 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.

    • 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 re-sealing the back panel. 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.

    • 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.

  19. Google Pixel 4 Battery Replacement, Remove the back panel: adım 20, 1 resimden 1.
    • 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.

  20. Google Pixel 4 Battery Replacement, Remove the adhesive strips: adım 21, 3 resimden 1. Google Pixel 4 Battery Replacement, Remove the adhesive strips: adım 21, 3 resimden 2. Google Pixel 4 Battery Replacement, Remove the adhesive strips: adım 21, 3 resimden 3.
    • Pull on the yellow pull tab of the adhesive strip 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.

  21. Google Pixel 4 Battery Replacement, Remove the battery: adım 22, 2 resimden 1. Google Pixel 4 Battery Replacement, Remove the battery: adım 22, 2 resimden 2.
    • 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.

    • 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.

    • 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.

    • If there's any alcohol solution remaining in the phone, carefully wipe it off with a lint-free cloth or allow it to air dry before installing your battery.

    • To install a replacement battery:

    • 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.

Nicholas Smyth - Yanıt

Hi Nicholas,

The iFixit kit should definitely have a T3 bit. Please contact our customer support and we will get the issue resolved!

Arthur Shi -

When you put it back together do you need to reheat the adhesive?

Keith P - Yanıt

Hey Keith,

When putting the phone back together and reinstalling the back panel, we recommend removing the old adhesive and installing new adhesive. The Pixel 4’s back panel adhesive can be found here, and a guide on how to install it can be found here!

If you’d like to reuse your old adhesive, try removing any large uneven chunks, reheat the adhesive, and press the back panel back into place.

Carsten Frauenheim -

Does the kit include replacement battery adhesive strips? I don’t recall seeing it in mine.
