Step-by-Step Guide to Remove the Battery from a Samsung S21
While it is possible to extract the battery from a Samsung S21, doing so requires caution and a step-by-step approach to avoid damaging your device. Here is a detailed procedure for safely removing the battery from your Samsung Galaxy S21:
Step 1: Power Off Your Device
The first step in any battery removal process is to ensure that your device is completely powered off. Long-press the power button and select “Power off.” Wait for your device to shut down entirely. This step is critical for your safety and for preventing short circuits.
Step 2: Gather Your Tools
Ensure you have all the necessary tools at your disposal. This will help you perform the battery removal swiftly and efficiently. Having everything you need on hand is crucial to avoid leaving your phone exposed for an extended period.
Step 3: Remove the SIM Card Tray
Before you proceed, locate the SIM card tray on the Samsung S21. Use the SIM card ejector tool to carefully remove the SIM card tray. This step will provide better access to the internal components of your phone.
Step 4: Heat the Edges of the Device
To soften the adhesive holding the screen in place, carefully apply heat along the edges of the phone. You can use a hairdryer or a heating pad for this process. The heat should be gentle; excessive heat can cause damage, so always be cautious.
Step 5: Insert the Suction Cup Tool
Once the edges are warm, take your suction cup tool and place it on the lower part of the screen. Gently pull the suction cup upward while sliding a plastic opening tool into the gap that forms. Start at the bottom and work your way around the sides to slowly detach the adhesive. You may need to reheat it as necessary to keep the adhesive soft.
Step 6: Release the Screen Clips
After releasing the adhesive, you should be able to lift the screen slightly. Use your plastic opening tool to carefully pry apart the clips holding the screen in place. Be gentle to avoid breaking these delicate components.
Step 7: Disconnect the Battery
Once you have accessed the internals, you will find the battery connector located near the center of the device. Use your tweezers to carefully disconnect the battery by gently lifting the connector out of its socket.
Step 8: Remove the Battery
Gently lift the battery from its slot. If there’s any adhesive holding it in place, you might have to apply a little heat again to loosen it. Be very careful during this step, as lithium-ion batteries can be fragile and might swell over time.
Step 9: Inspect and Replace (if necessary)
If you’re replacing the battery, make sure the new battery matches the original specifications. Inspect the old battery for any signs of damage or corrosion. If you notice any issues, it’s time for a replacement.
Step 10: Reassemble Your Device
After replacing the battery, reverse the disassembly process. Carefully reattach the screen, making sure to secure all clips and reapply adhesive where necessary. Reconnect the battery and the SIM card tray, and finally power on your device to ensure everything is functioning properly.

Choosing Authorized Service Centers
If you decide that professional help is necessary, always opt for authorized service centers or technicians. They have the right tools and expertise to handle your device safely and efficiently without voiding your warranty.
Warranty and Service Agreements
Always be aware of your device’s warranty. Attempting to repair or modify your phone may void your warranty terms, so evaluate your options carefully and review the service agreements from Samsung before proceeding with any DIY fixes.
Conclusion
