If your Samsung Galaxy S25 Plus is draining faster than usual, shutting down unexpectedly, or showing signs of a swollen back panel, it is time for a new battery. Modern Samsung devices now feature convenient pull tabs that make battery extraction much safer and simpler than older models. This guide will walk you through the process of safely opening the glass back, removing the wireless charging coil, and swapping out the degraded cell for a fresh one.
Required Tools
- Heat gun or hair dryer

Step 1: Power down and heat the device
Turn off your phone completely before starting any repairs.
Use a heat gun or hair dryer to apply even heat around the edges of the back glass for about two minutes to soften the waterproof adhesive.

Step 2: Create an opening gap
Apply a suction cup to the lower section of the back glass and pull up gently to create a tiny gap.
Insert a plastic guitar pick into this gap to prevent the adhesive from resealing.

Step 3: Slice the back glass adhesive
Slide the plastic pick around the entire perimeter of the phone to cut through the adhesive.
Be careful not to insert the pick too deeply near the camera module to avoid damaging the lenses, then carefully lift the back glass away.

Step 4: Remove the wireless charging coil
Locate the Phillips screws securing the wireless charging coil and NFC antenna assembly over the motherboard.
Extract these screws and use a plastic spudger to gently unclip the assembly, setting it aside safely.

Step 5: Disconnect the battery
Using your plastic spudger, immediately disconnect the main battery flex cable from the motherboard.
This is a critical safety measure that prevents accidental short circuits while you work on the internal components.

Step 6: Extract the old battery
The Galaxy S25 Plus features built in blue pull tabs for battery removal.
Grasp the tabs firmly and pull up steadily to release the battery from the chassis.
If the adhesive is stubborn, apply a few drops of isopropyl alcohol under the battery edges to loosen it.

Step 7: Install the replacement battery
Ensure the battery compartment is clean and free of leftover adhesive or alcohol residue.
Peel the protective liners off your new battery and press it firmly into the housing, ensuring the flex cable aligns perfectly with the motherboard socket.

Step 8: Reassemble the internal components
Connect the new battery cable to the motherboard.
Reinstall the wireless charging coil assembly over the top and secure it tightly with the original Phillips screws.

Step 9: Seal the back glass
Clean the old adhesive from both the phone frame and the back glass using isopropyl alcohol.
Apply the new precut adhesive to the frame, align the back glass, and apply steady pressure around the edges for several minutes to ensure a tight seal.

Frequently asked questions
Yes, breaking the original factory seal compromises the IP rating. You must apply a high quality precut adhesive and apply sustained pressure during reassembly to restore as much water resistance as possible.
It is highly recommended to calibrate your new battery for accurate percentage readings. Charge it uninterrupted to 100 percent, use the phone until it shuts off completely, and then charge it back to 100 percent.
If the tabs break, do not panic. Apply a few drops of high concentration isopropyl alcohol under the battery and wait a minute for the adhesive to dissolve. Then, use a flat plastic card to gently pry the battery out.
Absolutely not. Metal tools can easily puncture the soft outer shell of a lithium ion battery. A puncture can cause a dangerous thermal runaway event, leading to a fire or explosion.
