The Samsung Galaxy S21 is a flagship smartphone known for its impressive features and sleek design. However, there might come a time when you need to remove the battery for various reasons—whether to troubleshoot issues, replace a faulty battery, or perform a thorough cleaning. Unlike older Samsung devices, the Galaxy S21 comes with a non-removable battery design. This article will guide you through the process of battery removal, ensuring you do it correctly and safely.
Understanding the Samsung Galaxy S21 Battery Design
Before diving into the steps for battery removal, it’s essential to understand the battery design of the Samsung Galaxy S21. The device features a non-removable lithium-ion battery that is sealed inside the smartphone’s body. This design helps maintain the phone’s slim profile and durability but also makes altering or replacing components more complicated.

There are several reasons you might consider removing the battery from your Samsung Galaxy S21:
- Performing Resetting Procedures: A battery removal can sometimes help reset the device if it’s frozen or not responding.
- Replacing a Faulty Battery: If your battery health has deteriorated, replacing it can restore your device’s performance.
What You’ll Need Before Starting the Removal Process
Preparation is key when attempting to remove the battery from your Samsung Galaxy S21. Gather the following tools and items before starting:
- Precision Screwdriver Set: A small Phillips head screwdriver and a specialized tool for prying open the case.
- Plastic Pry Tools: Useful for carefully opening the phone without causing damage.

Step-by-Step Guide to Removing the Battery from Your Samsung Galaxy S21
Now that you are prepared, let’s dive into the detailed step-by-step process to safely remove the battery from your Samsung Galaxy S21.
Step 1: Power Off Your Device
Before you begin, make sure to turn off your Samsung Galaxy S21 completely. This prevents any electrical short circuits from occurring while you’re working.
Step 2: Remove the SIM Card Tray
Remove the SIM card tray using the SIM eject tool or a small paperclip. This step will give you easier access to the area near the phone’s edge, which will be helpful later during disassembly.
Step 3: Heat the Edges of the Phone
Using a heat gun or hair dryer, apply gentle heat along the edges of the Samsung Galaxy S21. This step is critical as it softens the adhesive that holds the back cover in place. Aim to warm the edges for about 30-60 seconds but be careful not to overheat the device.
Step 4: Pry Open the Back Cover
Once the edges of the device feel warm, use a plastic pry tool to carefully insert between the back cover and the device frame. Gently apply pressure to open the cover. Work your way around the device until it is completely separated from the back cover.
Step 5: Disconnect the Battery Connector
After removing the back cover, you will see the internal components of the device. Locate the battery connector—this is where the battery connects to the motherboard. Use your tweezers to carefully disconnect this connector from the motherboard.
Step 6: Remove the Battery
Removing the battery itself can be a bit tricky due to the adhesive that keeps it in place. Here are a few tips for this step:
Using Heat
If the battery feels stuck, you may need to apply gentle heat again to loosen the adhesive.
Using Pry Tools
Once the adhesive is softened, use a plastic pry tool to carefully lift the battery out of its compartment. Ensure you do this slowly and gently to avoid damage.
Step 7: Install a New Battery (if replacing)
If you are replacing the battery, simply position the new battery into the compartment and reconnect it to the motherboard by carefully pressing the battery connector back in place.
Step 8: Reassemble Your Device
Once the battery has been installed or removed, it’s time to put the back cover back on. Align the cover, press it down firmly, and ensure that it snaps back into place.
Step 9: Test Your Device
After reassembling your Samsung Galaxy S21, turn it back on and check if everything operates smoothly. If you experienced issues that prompted the battery removal, now is the time to see if they are resolved.

Is removing the battery from my Galaxy S21 safe?
While removing the battery from your Samsung Galaxy S21 is generally safe if you follow the proper procedures, it can still pose risks if not done correctly. The battery is secured with adhesive, and improper handling can lead to damage to internal components. Additionally, there’s a risk of voiding your warranty if the device has not been opened by an authorized technician.
To minimize these risks, make sure to work in a clean, dry environment and follow a detailed guide with step-by-step instructions. Using the right tools and going slowly can also help ensure a safe and successful battery removal experience.
What should I do if my battery is swollen?
If you notice that your Samsung Galaxy S21’s battery is swollen, it’s essential to handle the situation with care. A swollen battery can be a serious hazard, as it may leak or even implode. First, do not attempt to remove the battery if it is swollen, as it could be dangerous. Instead, seek professional assistance from an authorized repair center or Samsung support.
In the meantime, ensure that your device is turned off and store it in a cool, dry place away from flammable materials. Do not puncture or make any attempts to relieve the swelling as this could lead to further complications or accidents. Prioritizing safety in these situations is critical.
How can I tell if my battery needs to be replaced?
There are several signs that can indicate it’s time to replace the battery in your Samsung Galaxy S21. Common symptoms include a significant decrease in battery life, where the device drains faster than it used to, or the phone unexpectedly shutting down even when there is charge remaining. Additionally, if you notice physical deformation, such as swelling or bumps on the back of the device, it’s a strong indication that the battery is failing.
Another sign to look out for is overheating, where the device becomes excessively warm during regular use or charging. If you experience any of these issues, you should consider getting the battery checked or replaced to ensure optimal performance and safety.
Can I replace the battery myself, or should I go to a professional?
You can replace the battery yourself, but it is essential to weigh the pros and cons. If you are comfortable using tools and following detailed instructions, you may be able to complete the task successfully. There are many online guides and videos that can help. However, keep in mind that doing it yourself carries a risk of damaging the device further or voiding any existing warranty.
On the other hand, visiting a professional or an authorized Samsung repair center can provide peace of mind. Technicians who are trained specifically to work with Samsung devices will have the experience and tools necessary to handle battery replacements safely and efficiently. If you’re unsure about your skills or want to ensure the integrity of your device, seeking professional help is always a good option.
