Great point. That saved me! Thanks!

Ensure you position the new battery nearer to the side of the case to allow room for the connector wire to fold down in the gap on the right side.

No. Use new strips only.

I used a white terrycloth hand towel as my work surface and to position and retain all the screws and part in their relative positions, so I didn't mix things up. I also magnetized the screwdriver tips and that made it very easy to deal with these tiny, tiny screws.

The flat end of the spudger works great to position and press down on the connectors during reassembly.

This tool is worth its weight in gold to make opening the case without breaking things very easy. Highly recommend using it. I needed to use the little blue plastic pry bar tool on one side of the case to get the glass and frame to release from the back.

The plastic strips quickly broke off. I used a neck warmer that you heat in the microwave for 90 seconds to supply warmth to the back of the iPhone to soften the adhesive (just lay the back of the phone down on the neck warmer). This allowed me to slip an old credit card slowly under the battery by wiggling it a bit from side to side, then gently lifting on the card. I peeled the adhesive residue very slowly off the case back with the flat end of the spudger, while still resting the back of the phone on the neck warmer to keep it soft.

To reinstall the glass, I lined up the bottom edge first, then pivoted the top in. The magnets pulled it quickly into place.

I used surgical tweezers to put place these two tiny screws back in without dropping them into the computer.

To avoid the pain on my finger tips in applying enough force, I used a bit of microfiber towel as padding under the sharp plastic edge and it was then easy.
