Step-by-Step Battery Replacement Process
Step 1: Power Down Your Device
Hold the power button and select “Power Off.” Wait until the device is completely shut down before proceeding.
Step 2: Remove the SIM Card Tray
Use the SIM ejector tool to remove the SIM card tray from the top of the device. Set it aside in a safe place.
Step 3: Heat the Back Panel
Apply heat around the edges of the back glass panel using a heat gun or hair dryer for about 2-3 minutes. This softens the adhesive holding the back cover in place. Be careful not to overheat the device.
Step 4: Remove the Back Glass Panel
- Place a suction cup near the bottom edge of the back panel
- Gently pull up while inserting a plastic opening pick into the gap
- Carefully slide the pick around the edges to separate the adhesive
- Work slowly to avoid cracking the glass
- Lift the back panel off once all adhesive is separated (source: Nerdy Tech Blog)
Step 5: Remove the Midframe Screws
You’ll see several small Phillips screws holding the midframe in place. Remove all visible screws (typically 12-15 screws) and keep them organized, as they may be different sizes.
Step 6: Remove the Midframe
Carefully lift the plastic midframe away from the device. You may need to use a spudger to gently pry it up at the edges.
Step 7: Disconnect the Battery
This is a critical step:
- Locate the battery connector on the motherboard
- Use the flat end of a spudger to carefully disconnect the battery connector from its socket
- Pry gently upward to avoid damaging the connector (source: iFixit)
Step 8: Remove the Old Battery
The battery is held in place with strong adhesive strips:
- Apply gentle heat to the back of the phone (where the battery sits) to soften the adhesive
- Use a plastic spudger or opening pick to carefully pry up the battery
- Work slowly and avoid bending the battery excessively
- If there are pull tabs on the adhesive, gently pull them at a low angle
- Never use metal tools directly on the battery to prevent puncturing it
Step 9: Clean the Battery Compartment
Remove any remaining adhesive residue using isopropyl alcohol and a lint-free cloth. Ensure the area is completely clean and dry before installing the new battery.
Step 10: Install the New Battery
- Apply new adhesive strips to the battery compartment or to the back of the new battery
- Carefully position the new battery in place, ensuring proper alignment
- Press down firmly to secure the adhesive bond
- Make sure the battery connector is accessible and properly positioned
Step 11: Reconnect the Battery
Align the battery connector with its socket on the motherboard and press down gently until it clicks into place. Ensure a secure connection (source: Battery Spotlight).
Step 12: Reassemble the Midframe
- Replace the plastic midframe
- Reinstall all screws in their correct positions
- Ensure everything is seated properly before tightening
Step 13: Test Before Sealing
Before reattaching the back glass:
- Press and hold the power button to see if the device powers on
- Check that the battery is charging properly
- Verify all functions are working
Step 14: Reattach the Back Panel
- Clean both surfaces thoroughly
- Apply new adhesive around the edges of the frame
- Carefully position the back glass panel
- Press firmly around all edges to secure the seal
- You may want to place a book or weight on top for a few hours to ensure proper bonding
Step 15: Final Steps
- Reinsert the SIM card tray
- Charge your device fully before regular use
- Calibrate the battery by charging to 100%, then draining completely, then charging to 100% again

Preparing for Battery Replacement
Replacing the battery in a Samsung Galaxy S6 requires careful preparation. Safety, the right tools, and initial steps are all important for a successful battery change.
Safety Precautions
Safety is the first priority. Lithium-Ion batteries can be dangerous. Work in a well-ventilated area. Keep a fire extinguisher nearby. Handle the battery gently to avoid puncturing it. Wear safety glasses and gloves. Turn off your Samsung Galaxy S6 before starting.
Avoid overheating the battery. Using a heat gun or Iopener helps soften the adhesive but use low heat. This prevents the glass from cracking or the battery from catching fire. If using a microwave to warm up an Iopener, follow the instructions closely to avoid overheating it.
Required Tools and Parts
Gather all necessary tools and parts. You will need a Philips #00 screwdriver, spudger tool, plastic opening tool, tweezers, suction cup, and double-sided tape. Also, have a new battery ready. Use high concentration isopropyl alcohol to dissolve adhesive.
Get a heat gun or Iopener to loosen the adhesive. You may also need packing tape to prevent the back glass from shattering. Having the user manual nearby can guide you through the steps.
Initial Steps Before Opening the Device
Start by turning off your Samsung Galaxy S6. Remove the SIM card tray using a pin or SIM removal tool. This ensures you do not damage the SIM card slot during the process.
Use the heat gun or Iopener to soften the adhesive around the rear glass. Gently apply heat and use a suction cup to lift the glass. Insert a thin plastic opening tool underneath the glass to carefully separate it from the device.
Once the back cover is removed, locate the battery connector. Unscrew the Philips #00 screws that hold it in place. Detach the battery connector using the spudger. You are now ready to replace the battery.
