Step-by-step

1. 1

   Power Off Device

   1 min

   Press and hold the Power button on the right side of the device. Select 'Power off' on the screen and wait for the phone to shut down completely.

2. 2

   Wear Anti-Static Strap

   1 min

   Attach an anti-static wrist strap to your wrist and ground it to a grounded metal object. This protects sensitive internal electronics from static damage.

3. 3

   Locate Back Cover Pry Notch

   1 min

   Find the small fingernail indentation at the top edge of the phone near the 3.5mm headphone jack. This gives leverage to release the rear shell.

4. 4

   Insert Plastic Spudger

   1 min

   Insert the flat pry tip of a plastic spudger into the back cover notch. Avoid using metal tools to prevent cracking or scratching the plastic frame.

5. 5

   Pry Up Top Edge

   1 min

   Gently twist the spudger to pop open the top plastic retaining clips. You will hear a distinct snap as the cover separates.

6. 6

   Unclip Side Perimeter

   1 min

   Slide the spudger down along the left and right edges of the phone frame. Release all the plastic tabs along both sides.

7. 7

   Remove Rear Cover

   1 min

   Lift the rear cover away from the chassis once all perimeter clips are released. Set the cover aside in a clean workspace.

8. 8

   Locate Battery Recess

   1 min

   Identify the small pry notch located at the bottom rim of the battery compartment. This notch allows you to lift the old cell clear of its tray.

9. 9

   Lift Battery Out

   1 min

   Insert the edge of your spudger into the lower battery recess and lift upward. Remove the old battery from the device compartment.

10. 10

    Inspect Contact Pins

    1 min

    Examine the gold spring contacts inside the top of the battery compartment. Ensure none of the four metal pins are bent or dirty.

11. 11

    Clean Metal Terminals

    2 min

    Dampen a cotton swab with a drop of 99% isopropyl alcohol. Gently wipe the spring contacts to remove any residue or oxidation.

12. 12

    Unpack New Battery

    1 min

    Remove your replacement Galaxy S2 battery from its protective wrapping. Verify that the battery model match reads EB-F1A2GBU.

13. 13

    Align Gold Terminals

    1 min

    Angle the top end of the new battery into the bay so its golden contacts touch the phone's spring pins. Keep the lower end slightly raised.

14. 14

    Press Battery Into Place

    1 min

    Push down on the lower edge of the battery until it sits flat in the compartment. Ensure it rests flush with the surrounding frame.

15. 15

    Position Rear Cover

    1 min

    Place the rear cover onto the back of the phone, aligning the camera cutout with the camera module. Make sure the cover rests evenly.

16. 16

    Snap Cover Clips Closed

    1 min

    Press firmly along the outer edges of the rear cover until every clip snaps shut. Check around the entire border to confirm there are no gaps.
