Samsung Galaxy S25 FE Battery Replacement

Unplug all cables from your phone.

Completely power off your phone by holding the side key and volume down button and selecting Power off.

Apply strips of packing tape to the cracked glass until it's completely covered—this will help keep the glass contained and allow the suction cup to stick.

Make sure there's a single strip (not overlapping) of tape across the bottom edge, big enough for a suction cup to fit on.

Heat an iOpener and lay it on the bottom edge of the back cover for two minutes.

The cover is secured with adhesive around the perimeter of the frame. Use this picture as a reference while you separate the adhesive.

Apply a suction handle to the center of the back cover's bottom edge, as close to the edge as possible.

Pull up on the suction handle with strong, steady force until a gap forms between the back cover and frame.

Insert the tip of an opening pick into the gap.

Slide the opening pick along the bottom edge to separate the adhesive.

Slide the opening pick around the bottom right corner and up the right edge to separate the adhesive.

Slide the opening pick around the top right corner and along the top edge to separate the adhesive.

Slide the opening pick around the top left corner and down the left edge to separate the adhesive.

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

This is a good point to power on your phone and test all functions before sealing it up. Be sure to power your phone back down completely before you continue working.

Check your rear cameras for any smudges and gently wipe them with a clean, lint–free cloth if necessary.

Your replacement back cover adhesive will be applied to either the frame or the back cover. Use cutouts and contours to see where it lines up best. If it matches the back cover, follow this guide. If it matches the frame, use this guide.

Use the point of a spudger to pry up and disconnect the wireless charging coil press connector.

Use a screwdriver to remove the fourteen screws securing the wireless charging and loudspeaker assembly:

Six 3.5 mm‑long screws securing the wireless charging coil

Eight 3.5 mm‑long screws securing the loudspeaker

Use the point of a spudger to pry up and lift the left side of the loudspeaker to unclip it.

Use two hands to remove the wireless charging and loudspeaker assembly.

Use the point of a spudger to pry up and disconnect the battery press connector.

Use the point of a spudger to pry up and disconnect the interconnect and screen cable press connectors (three total) from the bottom edge of the motherboard.

Use the point of a spudger to pry up and disconnect the other ends of interconnect and screen cables from the bottom of the phone.

Remove the three cables you just disconnected.

Use your fingers to peel up the plastic tabs on the edges of the battery, starting at the black, circular arrow markings.

Hold the plastic tabs out of the way and remove the battery.

Remove the adhesive liner from the bottom of the battery.

Hold the battery above its recess and use your finger to reconnect the battery press connector—temporarily reconnecting the battery ensures it's sitting properly in its recess.

Lay the battery into its recess and press down firmly to secure it.

Disconnect the battery before continuing.

Slowly peel up and remove the old battery sleeve—most of the adhesive should come up with the sleeve.

If any adhesive is still on the frame, use a spudger or your fingers to remove it.
