Introduction

This guide shows how to remove and replace the wireless charging coil for your Pixel 3 XL.

The coil is heavily glued onto the battery. To prevent damage to the battery, you will need to use adhesive remover or high concentration isopropyl alcohol in order to detach the coil from the battery.

What you need

Step 1

              Heat the edge of the back cover

Heat an iOpener and apply it to the right edge of the back cover for a 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.
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

Step 2

              Create a gap under the back cover

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.

Step 3

              Loosen the right edge adhesives

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.

Step 6

              Slice through the remaining edges

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.
