Powering Down The Device
Power down your Samsung S21 Ultra before starting the battery replacement. Press and hold the power button until the power off menu appears, then select “Power Off” to ensure the device is completely shut down.

Installing The New Battery
Take the new replacement battery and align it with the battery connector. Connect it gently, ensuring it’s seated properly. Press down lightly to secure the connection. If necessary, reattach any screws to hold the connector in place.
Reassembling The Phone
Put the back cover back on the Samsung S21 Ultra. Align it correctly with the device body and press down firmly along the edges to ensure the adhesive seals. Restart your phone by pressing the power button, and check to see that the new battery is functioning correctly.
