Yup, this video helped me know what people were talking about. It worked and I didn’t rip or break anything…so far XD

Pablo is right, there IS a visible difference between the two yellow 2.0 mm standoff screws - make a note of which is which (label, drawing, etc.) when you’re at this step.

I followed John’s advice, and it went smoothly. My iPhone had a white outline of where the battery was on the back case (you can see the white lines in the photo), but I added a few more lines with a white marker just to make sure I would put the new battery in the correct place.

Followed Peter’s advice, and the battery came out no issues. Pull up one at a time (leaving the other adhesive strips in place), and pull the adhesive strip straight out, parallel to the table you’re working on. Instead of continuing to pull one long piece (like the photo in Step 25), I’d pull some, bunch in up in my fingers,then keep pulling. This allowed for more control over the phone and this step in general.

Just as a precaution: to guide where I’d put the battery back into place (I took it out while replacing the lightning connector), I marked with a metallic sharpie the outline of where the battery was, to help me make sure I put it back exactly where the original had been.

Yes! I marked one with a fine point sharpie to tell the difference. Super important to make a note of each piece, cable, and their position along the way!
