Follow this guide to remove or replace the battery in your Google Pixel 8a.

Lithium-ion batteries have a limited lifespan. If your phone doesn't hold a charge or dies unexpectedly, it might be time to replace the battery.

If your battery is swollen, take appropriate precautions.

You'll need replacement battery, back cover, and flash unit adhesives to complete this repair.

Note: Any repair can compromise the water resistance of your phone. Retaining water resistance after the repair will depend on how well you reapply the back cover adhesive.

Tools

Parts

Step 1

Let your Pixel's battery drain below 25% before starting this repair. A charged lithium‑ion battery may catch fire if damaged.
Unplug all cables from your phone.
Completely power off your phone.
Press the power and volume up buttons at the same time to bring up the shutdown menu.

Step 2

The back cover is secured with adhesive around the perimeter and near the cameras. To avoid damaging your phone's internals, note the following:
Unless stated otherwise, don't insert your tool more than 3 mm (the width of your opening tool's flat section) around the edges.
Don't insert your tool under the edges of the camera bump.

Step 3

Your opening tool has a flat end and a curved end. During the opening procedure, use the flat end and angle it so the tool's sharp edge points upward.
Insert the edge of an opening tool between the back cover and the frame, starting with a sharp corner of the tool to help separate the adhesive.

Step 4

Slide your opening tool along the bottom edge to separate the adhesive securing the back cover.

Step 5

Slide your opening tool around the bottom right corner and up the right edge, stopping at the bottom of the camera bump.
Remove your opening tool from under the back cover.

Step 6

Insert your opening tool under the top right corner of the back cover, just above the camera bump.
Slide your opening tool along the top edge, stopping at the top left corner just above the camera bump.
Remove your opening tool from under the back cover.

Step 7

Insert your opening tool under the left edge of the back cover, just below the camera bump.
Slide your opening tool down the left edge to separate the adhesive.

Step 8

A strip of adhesive above the camera bump secures the top edge of the back cover.
Insert an opening pick under the top left corner of the back cover until the tip is close to the top edge of the camera bump.
You can insert the opening pick more than 3 mm along the top edge.
Slide the pick to the right, stopping when you reach the right edge of the cameras.

Step 9

A final strip of adhesive below the camera bump secures the back cover.
Insert the flat edge of an opening pick under the back cover, just below the camera bump.
Insert a second opening pick in the same spot on the other side.

Step 10

Pry up simultaneously with both picks and apply constant pressure to separate the final piece of adhesive securing the back cover.
Be careful not to bend the back cover. If the adhesive feels stubborn, rotate the cover side-to-side to further loosen the adhesive.
If the adhesive isn't separating, you can lightly heat the back cover just below the camera bump with a hair dryer or iOpener to soften the adhesive.

Step 11

Remove the back cover.
During reassembly:
Now is a good time to test your phone before sealing it up. Power it on and check that it works. Power it back down before you continue reassembly.
Follow this guide to apply new adhesive and install your back cover.

Step 12

Use a hair dryer to heat the flash unit to soften the adhesive securing it to the logic board cover.
Alternatively, you can use an iOpener or heat gun to warm the flash.
Only heat the flash so it's warm to the touch. The battery and surrounding components are susceptible to heat damage.

Step 13

Slide your pick under the top edge of the flash and lift to separate the adhesive securing it to the cover.
Be careful not to slip and tear the flash cable, as it's very fragile.
During reassembly, follow this guide to replace the flash adhesives.

Step 14

Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.
While the Pixel 8a uses Torx Plus screws, standard Torx bits work. Make sure to apply constant, downward force to prevent stripping.
Use a Torx Plus 3IP screwdriver to remove the 15 screws securing the logic board cover:
Thirteen 4.3 mm‑long screws
Two 1.9 mm‑long screws

Step 15

Be very careful not to damage the spring contacts around your phone's perimeter. Only insert your tool where instructed.
Insert an opening pick under the bottom right corner of the logic board cover and pry up to release the clip.
Insert the tip of a spudger under the notch near the top right corner of the logic board cover (just below the screw hole) and pry up to release the clip.

Step 16

Slowly lift the top edge of the logic board cover and thread the flash unit through its cutout.
During reassembly, thread the flash through its cutout as you lower the logic board cover into place.

Step 17

Remove the logic board cover (which has the wireless charging coil connected to it).

Step 18

Use a pair of tweezers or your fingers to remove the metal cover on the right edge of your phone.
During reassembly, place the upper left corner of the cover under the hook on the logic board before laying it into place.

Step 19

This guide was shot with the Verizon model (G8HHN) Google Pixel 8a, which has an extra cable and connector for the 5G mmWave antenna (just to the left of the battery connector). If you have the non-mmWave model, just skip any steps that mention the antenna cable.

Step 20

Insert the flat end of a spudger under the right edge of the battery press connector and pry straight up to disconnect it.
To reconnect a press connector, align it over the socket and gently press down on one side until it clicks into place, then press down on the other side. It might take a few tries to align the connector.
To prevent damaging the surface mounted components around the battery and 5G mmWave connectors, only pry where instructed.

Step 21

Insert the point of a spudger under the bottom edge of the 5G mmWave antenna press connector and pry straight up to disconnect it.

Step 22

Move the battery and 5G mmWave cables out of the way of the battery.

Step 23

Gently move the graphite sheet out of the way of the battery.

Step 24

Gently fold the side button tab over the left edge of your phone, so it's out of the way of the battery.

Step 25

Two strips of adhesive secure the battery in its recess.
Flip your phone over and use a hair dryer, heat gun, or hot plate to evenly heat the screen until the entire frame is warm to the touch.
Be careful not to overheat the screen, as it's susceptible to heat damage. Don't concentrate the heat in any one spot.

Step 26

Insert the flat end of an opening pick between the left edge of the battery and the frame.

Step 27

Take care not to deform or puncture the battery—a damaged battery is a potential safety hazard.
Firmly secure the frame with one hand, and use your free hand to pry up the battery with the opening pick. Keep steady pressure on the pick for one minute.
If you're having trouble, try using a plastic card or two picks side by side to get more leverage.
If the battery really isn't budging, apply a few drops of highly-concentrated isopropyl alcohol (over 90%) to the left edge of the battery, elevate the left edge of your phone, and wait one minute for the adhesive to soften.
Once the adhesive begins to separate, slide your pick deeper under the battery and continue prying it up.

Step 28

Use your opening pick to lift the battery, separating any remaining adhesive.
Remove the battery.

Step 29

The next three steps show how to apply new adhesive and install your replacement battery.
Use the flat end of your spudger to scrape an edge of the old adhesive into a ball large enough to grip with a pair of tweezers.
Use tweezers or your fingers to peel and remove the old adhesive from the frame.
Apply a few drops of highly-concentrated isopropyl alcohol (over 90%) to any adhesive residue and wipe it with a lint-free or microfiber cloth.

Step 30

If your battery comes with adhesive pre-installed, remove its adhesive liners and skip this step.
Peel the large, clear liner from the two battery adhesive strips.
Alternatively, you can use strips of thin, double-sided tape to secure the battery.
Apply the strips to the battery recess, so the longer strip is on the left side.
Firmly press down along the length of both strips to secure the adhesive to the frame.
Remove the remaining blue liner from the strips.
