Google Pixel 9a Battery Installation

Use a spudger and tweezers to remove all the old battery adhesive from the frame.

Use high‑concentration (>90%) isopropyl alcohol and a lint‑free cloth (or coffee filters) to clean up and remove all the old adhesive residue from the frame.

Remove the larger, clear liner from your replacement battery adhesive.

Lay the adhesive into the battery recess so the strips align with their contours on the frame.

Use your fingers or a spudger to firmly press the adhesive into place, securing it to the frame.

Peel up and remove the remaining liner.

Gently flip the side button cable over the frame so it doesn't get stuck between the side of the battery and the frame in the next step.

Hold the battery above its recess and use your finger to push down and reconnect the battery press connector.

Lay the battery into its recess and press down firmly to secure it to the adhesive.

Once the battery's in place, disconnect it while you continue reassembly.

Use your finger to flip the side button cable onto the battery and gently press down to secure it with its tape.
