In this guide, we’ll explore the ins and outs of removing the battery from your Samsung S21, ensuring you do it safely and efficiently while maintaining the integrity of your device.
Understanding the Samsung Galaxy S21 Battery
Before delving into the removal process, it’s essential to understand a few key aspects of the Samsung S21 battery:
Battery Specifications
The Samsung S21 is equipped with a non-removable lithium-ion battery with a capacity of 4000 mAh. Lithium-ion batteries are preferred for their efficiency and compact size, but their non-removable design can make replacement or maintenance a bit challenging.
Signs You May Need to Remove the Battery
It’s important to recognize when you may need to consider battery removal. Here are some common indicators:
- Your device is frequently overheating.
- The battery drains rapidly despite minimal usage.
Understanding these signs can help you determine when it’s time to take action.
Gathering the Necessary Tools
Before you begin the battery removal process, gather the tools you’ll need. Proper preparation ensures that the procedure is smooth and efficient. Here’s a list of essential tools for the job:
- Small Phillips screwdriver
- Plastic pry tool or opening tool
- Sim card ejector tool
- Small container for screws
Having these tools ready will save you time and frustration during the process.
Step-by-Step Guide to Remove Battery from Samsung S21
Removing the battery from your Samsung S21 can be tricky due to its non-removable design. However, with patience and careful handling, you can do it yourself. Follow these detailed steps:
1. Power Off Your Device
Before beginning any procedure involving your smartphone’s internal components, always power off the device. This prevents any short circuits or electric shocks during the process.
2. Remove the SIM Card Tray
Using the sim card ejector tool, gently insert it into the small hole beside the SIM card tray to eject it. It’s important to clear this compartment to avoid damaging components while opening the device.
3. Heat the Back Cover
To facilitate the opening of the device, you need to soften the adhesive holding the back cover in place. Use a heat gun or a hairdryer on a low setting and gently warm the back cover for about 30 seconds. Be cautious to not overheat, as this could damage the internal components.
4. Open the Back Cover
Using a plastic pry tool, gently insert it between the back cover and the frame. Start at the edge and slowly work your way around. Be patient and apply gentle pressure to avoid cracking the glass. Once the adhesive starts to give way, you can lift the back cover off entirely.
5. Unscrew the Battery Connector Shield
With the back cover removed, you’ll see the internal components. The battery connector will be covered by a small metal shield, which is usually secured with a few screws. Using your Phillips screwdriver, carefully remove these screws and place them in your small container for safekeeping.
6. Disconnect the Battery
Once the shield is removed, you’ll locate the battery connector. Use your plastic pry tool to gently lift the connector from the motherboard. Be careful to not apply too much force, as this could damage the motherboard or connector.
7. Remove the Battery
With the battery disconnected, you can now remove it from the device. If it’s sticky or difficult to remove, you may gently pry it from the edges. Avoid using any metallic tools to prevent puncturing the battery.
Safety Precautions
As you complete this process, remember the following safety tips:
- Always handle batteries with care to prevent leaks or punctures.
- Recycle or dispose of old batteries according to local guidelines.
Reassembly: Installing a New Battery
If you have successfully removed the battery for replacement, reassembly is relatively straightforward:
1. Insert the New Battery
Carefully place your new battery into the dedicated slot. Ensure it fits snugly without forcing it.
2. Reconnect the Battery Connector
Utilize your plastic pry tool to reconnect the battery connector to the motherboard. Press it firmly but gently until you feel it secure.
3. Replace the Battery Connector Shield
Position the metal shield back over the battery connector and secure it using the screws you previously removed.
4. Reattach the Back Cover
Align the back cover with the device frame and press down firmly. The adhesive should hold it in place. If necessary, you can use additional adhesive or double-sided tape for a tighter fit.
5. Insert the SIM Card Tray
Finally, reinsert the SIM card tray into your device.
Troubleshooting Common Issues
Even after a successful battery installation or removal, issues may arise. Here are some common problems and troubleshooting tips:
Device Won’t Power On
If your device fails to turn on after battery removal, try the following steps:
1. Ensure Proper Connection
Double-check that the battery connector is seated properly.
2. Charge Your Device
Connect the device to a charger for at least 15 minutes. Sometimes the battery may not have enough charge to power up immediately.
Unexpected Shutdowns
If your device powers off unexpectedly, try the following:
1. Inspect the Battery
Make sure the battery is seated correctly and the contacts are clean.
2. Check for Software Issues
Outdated software may cause power management issues. Ensure your device is up to date.
Conclusion
Successfully removing and replacing the battery on your Samsung S21 can dramatically enhance the device’s performance and prolong its life. While this guide provides you with the necessary steps and precautions, it’s always recommended to consult with a professional technician if you’re uncomfortable performing the task yourself. Remember to always handle your device with care and to recycle or dispose of batteries responsibly for safety and environmental sustainability. By understanding the removal process, you’re one step closer to ensuring your Samsung S21 remains in optimal condition.

Is removing the battery from the Samsung S21 safe?
Removing the battery from the Samsung S21 is generally safe as long as you follow the proper procedures outlined in the guide. Samsung’s design may make battery removal seem daunting, but with the right tools and approach, the process can be completed without damaging the device.
It’s important to note that opening your phone may void any warranty. If you’re uncertain or uncomfortable with performing the battery removal yourself, it’s advisable to consult a professional technician or authorized service center for assistance. This ensures the integrity of your device is maintained.
Do I need to worry about static electricity when removing the battery?
Yes, static electricity can damage your device’s internal components when working on electronic devices like smartphones. To minimize the risk of static discharge, it’s advisable to work on an anti-static mat and wear an anti-static wrist strap.
Before handling the internal components, touch a grounded metal object to discharge any static electricity that may have built up in your body. This precaution helps protect sensitive components within your Samsung S21 from potential damage.
How do I know if the battery needs to be replaced?
Indications that your Samsung S21 battery may need replacement include rapidly draining battery life, difficulty charging, or swelling of the battery. If your device frequently shuts down despite having a charge or does not hold a charge for long, these are also signs of a failing battery.
Additionally, if your phone heats up excessively during charging or use, it may suggest an internal issue with the battery. Regular monitoring of these symptoms can help you decide the right time for a battery replacement.
What precautions should I take before attempting battery removal?
Before attempting to remove the battery from your Samsung S21, make sure to back up all of your important data.
