Samsung Galaxy S25 Battery Replacement
Follow this guide to replace a dead or worn-out battery in your Samsung Galaxy S25 smartphone.
Your phone's lithium‑ion battery has a limited lifespan. If your phone dies quickly, doesn't hold a charge, randomly shuts off with battery remaining, or only works when plugged in, you may need to replace the battery.
If your battery is swollen, take appropriate precautions.
Note: You'll need replacement back cover adhesive to complete this repair.
Some photos in this guide are from a different model and may contain slight visual discrepancies, but they won't affect the procedure.

Cracked glass preparation
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 the back cover
Heat an iOpener and lay it on the bottom edge of the back cover for two minutes.
-
-
Adhesive information
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
Apply a suction handle to the center of the back cover's bottom edge, as close to the edge as possible.
-
-
Insert an opening pick
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.
-
-
Separate the bottom edge adhesive
Slide the opening pick along the bottom edge to separate the adhesive.
-
-
Separate the right edge adhesive
Slide the opening pick around the bottom right corner and up the right edge to separate the adhesive.
-
-
Separate the top edge adhesive
Slide the opening pick around the top right corner and along the top edge to separate the adhesive.
-
-
Separate the left edge adhesive
Slide the opening pick around the top left corner and down the left edge to separate the adhesive.
-
-
Remove the back cover
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.
