Safety Precautions

Prioritize safety by completely powering off your phone before beginning any disassembly. Exercise caution when applying heat to avoid damaging internal components. Be extra careful not to puncture or bend the battery during removal to prevent any potential safety hazards.

Understand Steps

Familiarize yourself with each step of the battery replacement process before proceeding. Understand the sequence of actions required to safely remove and replace the battery. Follow each step meticulously to ensure a successful battery replacement.

Opening the Device

Heat Bottom Edge

  • Heat the bottom edge of the back cover using an iOpener for two minutes.

  • Apply consistent heat to soften the adhesive for easier removal.

  • Ensure the heat is evenly distributed along the bottom edge.

Separate Adhesive

Left Edge

  • Apply heat to the left edge of the back cover to facilitate its removal.

  • Use caution when heating this area to avoid damage to internal components.

  • Slide the opening pick along the left edge to separate the back cover from the frame.

Right Edge

  • Apply heat to the right edge of the back cover to loosen the adhesive.

  • Use a steady force when pulling up on the back cover to create a gap.

  • Slide the opening pick along the right edge to cut through the adhesive.

Corner Adhesive

  • Pay attention to the adhesive in the corners of the back cover.

  • Use heat and precision when removing the back cover from corners.

  • Ensure all adhesive residue is cleaned from the corners before reassembly.

Remove Back Cover

  • Remove the back cover carefully to avoid any damage to internal components.

  • Use a combination of tools to detach the back cover without causing cracks.

  • Take your time to ensure the back cover is removed smoothly.

Disassembling Internals

Unfasten Motherboard Bracket

Unfasten the screws securing the motherboard bracket to the frame. Use a Phillips screwdriver for this task. Keep track of the screws to avoid any misplacement issues during reassembly.

Remove Camera Shell

Carefully remove the camera shell to prevent damage. Take caution while detaching it to ensure the camera's functionality remains intact. Make sure the camera shell is safely removed before proceeding further.

Disconnect Components

Wireless Charging Coil

Detach the wireless charging coil carefully from its connector. Ensure a gentle yet firm grip when handling this component.

Loudspeaker

Disconnect the loudspeaker by gently releasing its connector. Handle with care to prevent any damage during disconnection.

Display Cable

Disconnect the display cable by carefully unlatching its connector. Avoid applying excessive force when detaching to prevent any harm to the cable.

Battery Removal Process

Apply Isopropyl Alcohol

To start the battery replacement process, apply isopropyl alcohol around the edges of the phone's back cover. This helps to loosen the adhesive holding the cover in place. Use a plastic card to gently pry open the back cover after applying the alcohol.

Once you have successfully removed the back cover, locate the screws securing the battery in place. Unscrew these carefully and set them aside in a safe place to avoid misplacement during reassembly later on.

Insert Opening Pick

Insert an opening pick or a plastic tool between the battery and the frame of the phone. Gently slide it along the edges to break any remaining adhesive bonds without damaging other components inside.

Carefully work your way around the battery, ensuring that you apply consistent pressure to separate it from the adhesive underneath. Take your time to avoid bending or puncturing the battery during this step.

Separate Battery Adhesive

After loosening all sides of the battery, carefully lift it from its position using a plastic card or a spudger tool. Be cautious not to bend or damage the battery while separating it from any remaining adhesive still clinging to its surface.

Inspect for any leftover adhesive residue on both the battery and inside of the phone. Clean these surfaces thoroughly with isopropyl alcohol and a clean cloth before proceeding with installing a new battery.

Remove Battery

With all adhesive fully detached, gently lift out the old battery from its housing. Ensure that no cables or connectors are still attached before completely removing it from inside the device.

Dispose of the old battery responsibly following local regulations for electronic waste recycling. Now you are ready to proceed with installing a new battery into your Galaxy S21 device for improved performance and longer usage times.

Handling Components

Disconnect Interconnect Cables

When disconnecting interconnect cables, start by locating the small connectors on the motherboard. Gently lift the connectors using a plastic spudger tool to avoid damage.

Be cautious not to apply too much force when removing the interconnect cables. A gentle wiggle and pull motion should suffice for safe disconnection.

Careful Component Removal

Wireless Coil

The wireless coil is a vital internal component responsible for wireless charging functionality. Handle it delicately to prevent any damage during removal.

When removing the wireless coil, ensure that you keep track of its orientation for correct reinstallation later on.

Loudspeaker

The loudspeaker plays a crucial role in audio output quality. Use a prying tool to carefully lift and remove the loudspeaker from its housing.

Avoid bending or damaging the loudspeaker flex cable during removal to maintain its functionality.

Reassembly Tips

Secure Connections

To ensure the secure connections of all components, double-check each connection point for proper alignment. Make sure connectors are firmly in place to prevent future issues. Test the connections by gently moving the components to see if they stay in place.

Loose connections can lead to poor device performance or even failure. It's crucial to verify that all connections are secure before proceeding with reassembly. Avoid forcing connections as this can damage delicate components.

Reattach Back Cover

When reattaching the back cover, align it carefully with the device frame. Apply gentle pressure evenly across the edges to snap it back into place securely. Check for any gaps or unevenness in the fit, which may indicate improper alignment.

A properly attached back cover ensures the device's structural integrity and protects internal components from dust and moisture. Take your time to align and secure the back cover correctly to maintain the device's aesthetics and functionality.

Test Device Functionality

After completing the reassembly process, test the device functionality thoroughly. Power on the device and check all functions such as screen responsiveness, camera operation, and audio output. Ensure that all buttons work correctly without sticking or malfunctioning.

Testing the device functionality is essential to confirm that all components were reassembled correctly. Check for any unusual sounds, overheating, or abnormal behavior during operation. Address any issues promptly to prevent further damage.
