Google Pixel 8a Battery Replacement - Google Pixel 8a

Step 1 | Prepare your Pixel for disassembly

Allow the Pixel's battery to drain below 25% to prevent potential fire hazards.

Disconnect all cables from the phone.
Purposefully shut down the device by pressing and holding the power button and volume up button simultaneously.

Step 2 | Adhesive information

Do not insert tools more than 3mm from edges unless specified.

Be cautious near camera areas and note adhesive securing back cover.
Avoid inserting tools under camera bump edges to prevent damage.

Step 3 | Insert an opening tool

Position the opening tool with its flat end angled, ensuring the sharp edge is facing upwards.

Insert the tool's edge between the back cover and frame at a sharp corner.
This will help to gently separate the adhesive.

Step 4 | Separate the perimeter adhesive

Use an opening tool to pry the back cover from the bottom edge, separating the adhesive.

Step 5

Slide your opening tool around the bottom right corner and up the right edge, stopping at the bottom of the camera bump.

Do not press too hard on the edges or risk damaging the phone casing.

Remove your opening tool from under the back cover.

Step 6

Insert your opening tool under the top right corner of the back cover.

Slide it along the top edge to the top left corner, keeping it just above the camera bump.
Remove your opening tool from under the back cover.

Step 7

Position the opening tool at the left edge of the back cover, near the camera.

Work the tool downward along the edge to break the adhesive bond.

Step 8 | Separate the camera bump adhesive

Locate the strip of adhesive above the camera bump securing the back cover.
Insert an opening pick under the top left corner of the back cover until it reaches the area near the camera bump.

The pick can be inserted more than 3 mm along the top edge without damage.

Slide the pick to the right, stopping when it reaches the right edge of the cameras.

Step 9

Locate the adhesive strip at the bottom of the camera bump.

Pry the back cover loose by inserting a flat-edged tool under it, near the camera bump.
Repeat this action on the opposite side with another tool to ensure both edges are separated.

Step 10

Apply equal pressure to both sides of the back cover using two picks.

Beware of bending the back cover.

If adhesive is resistant, gently rotate the cover side-to-side.
If separation persists, lightly heat the area below the camera bump with a hair dryer or iOpener to soften the adhesive.

Step 11 | Remove the back cover

Remove the back cover.

Before sealing, power on your phone and verify its functionality.
Power off your phone before proceeding with reassembly.
Apply new adhesive and install the back cover as per this guide.

Step 12 | Separate the flash unit

Heat the flash unit carefully to avoid damaging nearby components.

Use a hair dryer, iOpener, or heat gun to gently warm the flash unit.
Aim for a temperature where the flash feels only warm to the touch.

Do not apply excessive heat, as it can damage the battery and surrounding components.

Step 13

Slide a pick under the top edge of the flash and lift to separate the adhesive.

Be careful not to slip and damage the fragile flash cable.

Follow the reassembly guide for replacing the flash adhesives.

Step 14 | Unclip the logic board cover

Keep track of each screw and ensure it returns to its original location.

Use a Torx Plus 3IP screwdriver for the logic board cover, as standard Torx bits may not fit properly; applying constant downward force will help prevent stripping.

Remove the 15 screws securing the logic board cover using the Torx Plus 3IP screwdriver:

Thirteen 4.3 mm-long screws:
Two 1.9 mm-long screws.

Step 15

Careful not to damage the spring contacts around your phone's perimeter.

Insert an opening pick under the bottom right corner of the logic board cover, then pry up to release the clip.
Insert a spudger tip under the notch near the top right corner (below the screw hole), and pry up to release the second clip.

Step 16

Slowly lift the logic board cover's top edge.

Thread the flash unit through its cutout.

Be careful not to damage the logic board or surrounding components during this process.

During reassembly, lower the logic board cover into place while threading the flash unit through its cutout.

Step 17 | Remove the wireless charging assembly

Remove the logic board cover, taking care not to damage the attached wireless charging coil.

Step 18 | Disconnect the battery

Remove the metal cover on the right edge using tweezers or fingers.

During reassembly, position the upper left corner of the cover under the logic board hook.
Place the cover into position with the hook securely attached.

Step 19

This guide was created using a Verizon model (G8HHN) Google Pixel 8a.

Not all models have an extra cable and connector for the 5G mmWave antenna.
If your device has this setup, proceed with the instructions that mention the antenna cable.
If not, skip any relevant steps.

Step 20

Insert the flat end of a spudger under the right edge of the battery press connector and pry straight up.

Only pry where instructed to prevent damaging surface mounted components around the battery and 5G mmWave connectors.

To reconnect, align the press connector 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 correctly.

Step 21 | Disconnect the 5G mmWave antenna

Locate the 5G mmWave antenna press connector. Insert the point of a spudger under its bottom edge, then gently pry straight up to release.

Step 22 | Move the cables

Route the battery cable and 5G mmWave cable aside to access the area under the battery.

Step 23

Move the graphite sheet gently to access the battery.

Step 24

Fold the side button tab gently over the left edge of your phone to keep it away from the battery.

Step 25 | Heat the battery adhesive

Don't concentrate heat on a single spot — risk of heat damage.

Apply even heat to the phone's frame using a hair dryer, heat gun, or hot plate.

The screen should warm up evenly, but be careful not to overheat it.

Step 26 | Pry up the battery

Insert opening pick into gap at left edge of battery, near frame.

Step 27

Do not damage or puncture the battery — a damaged battery poses safety risks.

Secure the frame with one hand and pry up the battery using an opening pick in your free hand. Maintain steady pressure for one minute.
If necessary, use multiple picks side by side or a plastic card to increase leverage.
As a last resort, apply highly-concentrated isopropyl alcohol (over 90%) to the left edge of the battery and wait one minute for the adhesive to soften.

Step 28 | Remove the battery

Use your opening pick to carefully separate the battery from its adhesive.

Lift the battery off the device.
Set aside the removed battery.

Step 29 | Reassembly instructions

Remove old adhesive by scraping it into a ball using the flat end of your spudger.

Use tweezers or your fingers to peel off the old adhesive from the frame.
Apply a few drops of highly-concentrated isopropyl alcohol (over 90%) to any remaining residue and wipe with a lint-free cloth.

Step 30

Remove pre-installed adhesive liners if your battery has them.

Pull off the large, clear liner from each battery adhesive strip.
(Optional): Use thin, double-sided tape instead of strips.
Apply both strips to the recess, with the longer one on the left side.
Firmly press down along each strip to secure it to the frame.

Do not remove blue liners until adhesive is fully pressed in place.

Step 31

Place the battery in its designated recess.

Ensure the side button tab is not trapped between the battery and the surrounding frame.

Firmly press the battery into place to secure it.
