1. How to Replace Google Pixel 3a-XL Battery • hornetsecurity.com

Replacing a battery in a Google Pixel 3a-XL smartphone may seem like a daunting task, but it’s not as intimidating as you might think. With the right tools and a little patience, you can do this yourself and save a significant amount of money over having it done by a professional. This guide will provide you with detailed instructions on how to replace the battery in your Pixel 3a-XL safely and efficiently.

Before you begin, gather the necessary tools: a Phillips #00 screwdriver, a small pry tool (such as a plastic spudger or guitar pick), a new Pixel 3a-XL battery, and a heat gun or hair dryer. Ensure your smartphone is powered off, and you have ample workspace with good lighting.

First, remove the SIM card tray and loosen the two screws located at the bottom of the phone. Heat the back cover of the phone with a heat gun or hair dryer for a few seconds to soften the adhesive holding it in place. Carefully insert the pry tool into the gap between the back cover and the frame and gently pry the cover loose. Be patient and work your way around the edges until the back cover separates from the frame.

Tools and Materials Required

Essential Equipment:

1. Tri-point Screwdriver: Specifically designed for removing tri-point Y000 screws found on the Pixel 3a XL. Ensure it has a strong magnetic tip to securely hold onto the screws.

2. Phillips #00 Screwdriver: For removing the Phillips PH00 screws holding the battery in place.

3. Plastic Pry Tools: Thin, flexible tools that gently pry open the device’s casing without causing damage. Include sizes ranging from thin to slightly thicker for different areas of the phone.

Step 1: Power Down and Safety Precautions

Before you begin, it’s crucial to take the following safety measures:

Power Down the Device

Before you start, power off your Pixel 3a XL. To do this, press and hold the power button on the right side of the phone for a few seconds. Then, tap the “Power off” button that appears on the screen. This will ensure that no electricity is flowing through the device while you’re working on it, reducing the risk of electrical shock or damage to the phone.

Prepare Your Workspace

Find a clean, well-lit workspace where you have plenty of room to work. Lay down a soft cloth or towel to protect your phone from scratches. Gather the necessary tools, including a small Phillips #00 screwdriver, a spudger or plastic opening tool, and a pair of tweezers (optional).

Anti-Static Precautions

Static electricity can damage the sensitive components of your phone. To minimize the risk of static discharge, ground yourself by touching a metal object, such as a doorknob or faucet. You can also wear an anti-static wrist strap if you have one.

Safety Measure	Why it’s Important
Power down the device	Prevents electrical shock
Prepare your workspace	Ensures a clean and safe environment
Anti-static precautions	Prevents damage to sensitive components

Step 2: Remove the Back Panel

3. Heat the Back Panel

To loosen the adhesive that secures the back panel, you’ll need to apply heat. Use a hair dryer or heat gun to warm up the edges of the panel, focusing on the area where the adhesive strip is located. Heat the back panel evenly for about 1-2 minutes, taking care not to overheat it.

Tip	Description
Don’t use too much heat	Excessive heat can damage the device’s components.
Move the heat gun/hair dryer constantly	Concentrated heat in one area can create hotspots and weaken the back panel.

4. Insert a Pick into the Seam

Once the back panel is warm enough, insert a thin, plastic pry tool or spudger into the seam between the back panel and the frame. Gently wiggle the tool back and forth to create a small gap. Be careful not to insert the tool too deeply, as you could damage the device’s internals.

5. Slide the Pick Around the Edges

Continue inserting and sliding the pry tool around the edges of the back panel, carefully separating it from the frame. Use moderate pressure and avoid twisting the tool, as this could break the back panel. As you go around the edges, you may need to reapply heat to soften the adhesive.

Step 3: Disconnect the Battery

Before handling the battery, discharge it below 25%. A charged lithium-ion battery can catch fire and/or explode if punctured. To discharge the battery, turn off the phone and leave it on for several hours or overnight.

Once the battery is discharged, power off the phone and disconnect the battery connector using a spudger or your fingernail. The battery connector is a small, black connector located on the bottom of the motherboard.

Battery Removal Tips

Be careful not to damage the battery by puncturing it with a sharp object.

If the battery is stuck to the phone, you can use a heat gun or hair dryer to loosen the adhesive. Be careful not to overheat the battery, as this can damage it.

Once the battery is removed, be sure to dispose of it properly. Lithium-ion batteries are considered hazardous waste and should not be disposed of in the trash. You can find more information on how to dispose of lithium-ion batteries at the website of your local waste management authority.

Tools Required:	Spudger or fingernail

Step 4: Remove the Old Battery

Now that the screws are removed and the backpanel lifted, you’ll need to remove the battery connector that connects the battery to the logic board.

Step 5: Disconnect Battery Connector

Use the spudger to gently pry up the battery connector. This can be a bit tricky, so be careful not to tear the connector or short out the battery. Once the connector is loose, use your fingers to disconnect it.

Caution!

When working with sensitive components like batteries, it’s important to be extra cautious and avoid short circuits. Always power off your device before any repairs and use appropriate tools and ESD protection to prevent damage.

Once you’ve disconnected the battery, you’re free to remove the old battery. Be careful not to bend or dent the battery, as this could damage it. Insert a plastic card between the battery and the frame of your device.

Gently pry up the battery until it comes loose. Use your fingers to grab the battery and pull it out of the device. How about that? You’ve successfully removed the old battery, leaving you one step closer to installing a brand-new one!

Step 5: Install the New Battery

Now that the old battery has been removed, it’s time to install the new one. Carefully align the new battery with the contacts on the phone and gently press it into place. Make sure it is securely seated, but avoid applying excessive force.

### Cautions for Installing the New Battery

Once the new battery is installed, replace the back cover of the phone and secure it with the screws. Double-check to make sure the cover is properly aligned and all the screws are tightened.

Step 6: Connect the Battery

Now that the battery is in place, it’s time to connect it to the motherboard. Locate the battery connector on the motherboard and carefully align the battery’s connector with it. Ensure that the connectors are properly aligned and press them together firmly.

Step 7: Secure the Battery

a) Test the Battery:

Before securing the battery in place, double-check its functionality. Turn on your Pixel 3a XL and confirm that it powers up normally. If it doesn’t, verify that the battery connector is properly attached.

b) Apply Battery Adhesive:

Remove the battery adhesive from the packaging and cut it to the appropriate size. Carefully apply the adhesive to the edges of the battery, ensuring that it bonds to both the battery and the device’s chassis.

c) Secure the Battery:

Place the battery firmly in its designated compartment and press down on it to ensure it’s properly secured. The adhesive should provide enough grip to keep the battery in place.

d) Reassemble the Device:

Follow the previous steps in reverse order to reassemble your Pixel 3a XL. Once everything is securely fastened, turn on the device to verify if the battery replacement was successful.

Step 7: Reassemble the Device

Once the battery is in place, you can start reassembling the device. Start by pressing down on the back of the device to snap it into place. Then, connect the battery cable to the motherboard. Be sure to press down firmly on the connector to ensure a secure connection.

Next, place the SIM card and microSD card into their respective slots. Finally, screw in the four screws that hold the back plate in place.

Step 8: Test the New Battery

Once the device is reassembled, turn it on and check if the new battery is working properly. The battery should charge and hold a charge as expected. If you have any problems with the new battery, contact Google support for assistance.
