Step 3: Remove the Old Battery

With the Pixel 4A disassembled, the next critical step is to carefully remove the old battery from the device. The battery is a vital component, and its removal requires precision and caution to avoid damage to the surrounding parts and ensure a safe extraction. Here's a detailed guide on how to remove the old battery from your Pixel 4A:

Assess the Battery Placement

Before proceeding, take a moment to locate the battery within the device. In most smartphones, including the Pixel 4A, the battery is typically positioned near the center or bottom of the device, secured in place with adhesive and possibly additional fasteners. Identifying the battery's exact placement will provide clarity as you prepare to detach it from the device's framework.

Loosen the Adhesive

The battery in the Pixel 4A is often secured with strong adhesive to keep it in place. To release the battery, carefully insert a plastic opening tool or a spudger underneath the edge of the battery. Gently pry upwards, applying even pressure to gradually loosen the adhesive bond. It's crucial to exercise patience and avoid using excessive force to prevent unintended damage to the battery or the device's internal components.

Disconnect Any Remaining Connectors

In some smartphone models, including the Pixel 4A, the battery may have additional connectors or flex cables attached to it. If this is the case, carefully inspect the battery to ensure that all connectors and cables are identified. Using a spudger tool, delicately disconnect any remaining connectors from the battery, taking care not to damage the connectors or the cables themselves.

Lift and Remove the Battery

Once the adhesive is sufficiently loosened, and all connectors are detached, gently lift the battery from its position within the device. Exercise caution to avoid bending or puncturing the battery, as lithium-ion batteries are sensitive and should be handled with care. If the battery resists removal, re-evaluate the adhesive and connectors to ensure that all securing elements have been properly addressed before proceeding.

Secure the Removed Battery

After successfully removing the old battery, place it in a secure location away from any potential sources of damage or heat. Properly disposing of the old battery in accordance with local regulations is essential, as lithium-ion batteries require special handling and recycling procedures to minimize environmental impact.

By meticulously following these steps, you'll effectively remove the old battery from your Pixel 4A, paving the way for the subsequent installation of the new battery in the upcoming step.
