In this comprehensive guide, we will walk you through the process step-by-step, ensuring your experience is smooth and safe.
Why Remove the Battery from Your Samsung S21 Ultra?
Before diving into the intricate steps of battery removal, it’s worth noting why you might consider doing this. There are several reasons for needing to remove or replace the battery in your Samsung S21 Ultra:

Before you start the battery removal process, proper preparation is key. Follow these steps to ensure a smooth operation:
Gather Necessary Tools
You will need the following tools:
- Small Phillips screwdriver
- Plastic pry tool or spudger
- Fine-tip tweezers (optional)
- Heat gun or hairdryer (for loosening adhesive)
Backup Your Data
Before any repair or maintenance work, it’s essential to backup your data. Use Samsung Cloud, Google Drive, or any other cloud service to save your important files, contacts, and photos.
Power Down Your Device
Always turn off your Samsung S21 Ultra before attempting to remove the battery. This will prevent any accidental damage or short-circuiting during the process.
Step-by-Step Guide to Removing the Battery
Now that you are fully prepared, follow these detailed steps to remove your Samsung S21 Ultra battery:
Step 1: Heat the Edges of the Screen
Using a heat gun or a hairdryer, apply gentle heat to the edges of your device. This helps loosen the adhesive that holds the screen in place. Take care not to overheat the device – aim for approximately 80°C (176°F).
Step 2: Prepare for Opening the Device

Important Note
Make sure not to insert the tool too deeply to avoid damaging internal components, including battery connections.
Step 3: Detach the Back Cover
Continue sliding the pry tool along the edges until you successfully detach the back cover. Be patient and take your time to ensure that the adhesive is completely released.
Step 4: Disconnect the Battery
With the back cover removed, locate the battery connector. It is usually found near the battery itself and is secured by a plastic cover. Remove the screws holding the cover with your Phillips screwdriver, and gently lift it off.
Disconnecting the Battery
Once the cover is off, use a plastic pry tool to lift the battery connector gently. Make sure to work carefully to avoid damaging any nearby components.
Step 5: Remove the Battery
With the connector detached, it is now time to remove the battery. Some batteries may be glued, so you may need to apply heat again to loosen any remaining adhesive. Slowly and carefully lift the battery from its compartment.
Important Safety Precaution
If the battery feels swollen or shows signs of damage, it’s crucial to handle it with care. In such cases, follow proper disposal guidelines and consider seeking professional help.
