This guide shows how to remove and replace a worn out battery for your Pixel 3 XL.
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. If your battery is swollen, take appropriate precautions.
Replacing the battery requires un-gluing the wireless charging coil from it and transferring the coil to a replacement battery.

-
Heat an iOpener and apply it to the right edge of the back cover for a minute.
-
While you wait, note the following areas on the back cover:
-
Strong adhesive—there are large patches of adhesive near the bottom of the phone.
-
Fingerprint sensor cable—be careful not to slice through the cable as you pry
-
-
-
Apply a suction cup to the heated edge of the back cover, as close to the edge as possible.
-
Pull up on the suction cup with strong, steady force to create a gap.
-
Depending on the age of your phone, this may be difficult. If you are having trouble, apply heat to the edge and try again.
-
Insert the point of an opening pick into the gap.
-
-
-
Slide the opening pick along the right edge to slice through the adhesive.
-
The adhesive gums up and becomes hard to slice once it cools. If that happens, re-apply heat to the edge to make slicing easier.
-
Once you have sliced through the edge, leave an opening pick in the seam to prevent the adhesive from re-sealing.
-
-
-
Apply a heated iOpener to the bottom of the back cover for a minute.
-
-
-
Use an opening pick to slice around the bottom right corner and continue along the bottom edge of the phone.
-
Leave a pick in the edge to prevent the adhesive from re-sealing.
-
-
-
Continue heating and slicing the remaining edges of the phone.
-
Be careful as you slice along the left edge of the phone. If your pick feels like it's stuck near the top, you may have snagged the fingerprint sensor. Retract the pick out of the seam slightly and try again.
-
Be sure to cut through the thick portions of adhesive near the bottom and right edge of the phone.
-
-
-
Gently pry up the right edge of the back cover.
-
Use an opening pick to slice through any remaining adhesive along the edges.
-
-
-
Swing the right edge of the back cover upwards and rest the flipped panel along the left side of the phone.
-
-
-
User tweezers to carefully peel up the yellow tape over the fingerprint sensor connector.
-
-
-
-
Use the point of a spudger to carefully flip up the black lock bar on the fingerprint sensor's ZIF socket.
-
Grasp the cable's tab with your fingers or tweezers and gently walk the flex cable out of the socket.
-
-
-
Remove the following four T3 screws securing the metal cover bracket:
-
Three 4 mm long screws
-
One 3 mm long screw
-
-
-
Insert the flat end of a spudger underneath the top right edge of the metal bracket and pry up to loosen it.
-
Remove the metal cover bracket.
-
-
-
Use the point of a spudger to pry up and disconnect the battery connector from its socket.
-
Bend the battery cable such that the connector will not accidentally touch the socket.
-
-
-
Use the point of a spudger to pry up and disconnect the charging coil connector from motherboard near the right edge of the phone.
-
-
-
Insert the point of an opening pick underneath one edge of the charging coil.
-
Slide the pick along the edge to loosen the adhesive.
-
-
-
Tilt the edge you have been slicing upwards.
-
While holding the phone in a tilted position, apply a few drops of adhesive remover or high concentration isopropyl alcohol along the edge.
-
Keep the phone in that position for a minute or two to allow the adhesive to soften.
-
-
-
Insert the flat end of an opening pick underneath a corner of the charging coil.
-
Push the pick slowly and firmly under the coil to loosen the adhesive.
-
The adhesive is mostly around the perimeter of the wireless coil. Use the opening pick to slowly slice through the adhesive.
-
-
-
Remove the wireless charging coil.
-
Be sure to clean off the battery surface of any adhesive residue. Be very careful not to puncture the battery.
-
Connect the wireless coil connector to its motherboard socket. This ensures that the coil is properly aligned.
-
Peel off any adhesive backing on the replacement coil.
-
Lay the coil on top of the battery and firmly press it into position.
-
-
-
Remove the two 3 mm-long T3 screws securing the button array connector bracket.
-
Remove the button array connector bracket.
-
-
-
Use the point of a spudger to pry up and disconnect the button array connector from its motherboard socket.
-
-
-
Insert the point of a spudger into the gap along the top edge of the battery.
-
Slowly slide the point along the gap to lift up and detach the insulating tape from the battery.
-
Fold the tape away from the battery.
-
-
-
Carefully slide the point of a spudger underneath the yellow battery pull tabs folded along the top edge of the battery.
-
Separate the pull tabs from the battery.
-
-
-
Insert the flat end of an opening pick into the gap above the battery, behind a yellow pull tab.
-
Wedge the pick firmly underneath the battery. The pick will serve as a buffer for the adhesive strip as well as a prying point.
-
-
-
Pull on the yellow adhesive pull tab with slow steady force. Try your best to pull it as shallow of an angle (vs. straight up) as possible.
-
As you pull on the adhesive tab, maintain pressure on the opening pick to wedge it underneath the battery as much as possible.
-
Repeat the process with the second adhesive pull tab.
-
-
-
Remove the battery.
-
Remove any remaining adhesive from the battery well.
-
Temporarily re-connect the battery connector to its motherboard socket. This ensures that the battery will be properly aligned.

Lay the battery in the phone and press it firmly in place.
-
Disconnect the battery connector from its motherboard socket and resume reassembly.

To reassemble your device, follow these instructions in reverse order.
For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.
Take your e-waste to an R2 or e-Stewards certified recycler.

Very helpful, thank you! I was able to replace my battery pretty easily thanks to this guide.
Hey. After installing ney battery and new usb port my Pixel 3 has problems with microphones. Its only works with phoning via speakers. can you help me ?
Hi Kevin,
Assuming that you did not remove the motherboard (which houses a mic), it sounds like something may be off with the daughterboard, which surrounds the USB port and houses the other microphone. I would suggest carefully disconnecting and re-seating the daughterboard connectors, and making sure that the microphone is aligned to the port.
Thanks for these great instructions.
I followed them, and managed to replace my old Pixel 3 XL battery without any problems.
What about re attaching the charging coil? The adhesive is now shot on the coil. What should you do to adhere the coil to the new battery?
