Samsung Galaxy S25 FE Battery Replacement

Do not start repair with a fully charged battery - risk of explosion.

• Disconnect all external cables from your Galaxy device.
• Hold the side key and volume down button to power off your phone completely.

Glass shards can cause injury; cracked back glass must be addressed before disassembly.

• Apply non-overlapping strips of packing tape over the cracked glass, covering it completely.
• Ensure a single strip of tape spans the bottom edge, allowing a suction cup to fit.
• Avoid applying tape to the phone's frame; only cover the glass itself.
• Consider wearing safety glasses during this repair to protect against flying glass debris.

Follow the heat gun safety guidelines carefully to avoid damage.

• Note: The adhesive can be softened using an iOpener, hair dryer, or heat gun.
• Lay a heated iOpener on the bottom edge of the back cover for two minutes.
• Alternatively, use a hair dryer or heat gun to warm the cover.

Ensure the back cover has reached optimal heat for removal.

• Reference the provided image when separating the adhesive perimeter.
• Insert tool carefully under the cover near cameras, taking care not to damage them.

Position the suction handle on the center of the back cover's lower edge, keeping it as close to the edge as feasible.

Apply firm, consistent pressure to the suction handle.

• A gap should form between the back cover and frame.

• Be cautious of hot temperatures.

• Hold the phone down with your lifting hand or steady the frame with your free hand.
• Insert the tip of an opening pick into the gap.

Apply heat if the back cover feels stuck.

• Use an opening pick to slide along the bottom edge.
• Separate the adhesive as you go.

Position the opening pick at the bottom right corner of the device.

• Slide the tool upward along the right edge, applying gentle pressure.
• Continue until the adhesive is separated completely.

• Insert the pick just a few millimeters near the cameras to prevent damage.
• Move the pick around the top right corner and along the top edge to loosen the adhesive.

Slide opening pick around top left corner, then down left edge.

• Separate adhesive using smooth, consistent motion.

Use a suction handle to lift and remove the back cover.

If the cover feels stuck, go around the perimeter with an opening pick and separate any remaining adhesive.

• Power on your phone and test all functions before reassembly.
• Power down your phone completely before continuing.

Check rear cameras for smudges, wiping them gently with a clean, lint-free cloth if necessary.

• Apply replacement adhesive to either the frame or the back cover.
• Use cutouts and contours to align it correctly. If applying to the back cover, follow this guide; if to the frame, use that guide.

Use the tip of a spudger to carefully pry up the wireless charging coil press connector.

Keep track of all screws during this repair to prevent damage.

• Remove six 3.5 mm screws from the wireless charging coil using a screwdriver.
• Next, remove eight 3.5 mm screws securing the loudspeaker assembly.

Make sure to replace each screw in its original position.

• Use the pointed end of a spudger to gently pry up the left side of the loudspeaker and unclip it.
• During reassembly, press firmly around the perimeter of the loudspeaker to secure its clips in place.

Hold the wireless charging and loudspeaker assembly with both hands.

• Grasp the assembly firmly from either side.

Pry carefully, as damage can occur.

• Locate the gold arrow near each press connector for correct prying location.
• Use a spudger point to pry up and disconnect each battery press connector.

Use a spudger to carefully pry up the three interconnect and screen cable press connectors at the bottom edge of the motherboard.

• Pry up interconnect and screen cable ends using the point of a spudger.
• Disconnect these cables from the phone's bottom.

Remove the three cables.

Avoid puncturing or denting the battery — risk of chemical leakage and fire.

Only use a blunt tool or your fingers to handle the battery.

• Use your fingers to lift up the plastic tabs, starting at the black arrow markings on the battery edges.
• If needed, use an opening pick to gently pry the tab until you can grip it with your fingers.

Hold the plastic tabs out of the way.

• Remove the battery if it feels stuck, do not force it out.
• Ensure all plastic tabs are fully out of the way for easy removal.

Do not force a stuck battery out.

During reassembly:

• The replacement battery's sleeve may differ from the original, ensure it matches the original.
• Remove the adhesive liner from the bottom of the new battery.
• Temporarily reconnect the battery press connector by holding the battery above its recess and reattaching with your finger.
• Lay the battery into its recess and press down firmly to secure it.

Disconnect the battery before continuing.

Do not use tools to scrape off remaining adhesive from the metallic vapor chamber.

Peel up old battery sleeve, taking most of adhesive with it.

• If adhesive remains on frame, carefully remove using a spudger or your fingers.
