This step is not well explained. For some models of 2012 you need to disconnect this to be able to remove the motherboard and unscrew the hdd. However, this looks very fragile, and many people screw this sensor. If someone has been successful it would be nice if they can develop this. How to disconnect and how to re-connect it. thanks.

Just use two iFixit screwdrivers and pull

This was the second repair in the same iphone5. First was the screen, and all the screws came easily. After a year, I wanted to change the battery. From the two Pentalobe screws, one came easy. The other just turn but did not come out. I search and tried to glue the screw with superglue to the screw-driver, but did not work. Finally, I separated the glass from the phone, removed the button, and pushed the screw from inside to outside. It came just enough I could catch it with tweezers and turned meanwhile pulling. Finally came out. I know, not the best solution, but I did not find another way. I put the battery and works.

My battery connector looks like the energy star (6+12 pins) but on the motherboard says “apple inc 820-2279-A “ and no ‘energy star’ is written. I assume I should get the energy star model because is identical to mine. However, iFixit points to follow what is written on the board. So, something wrong here…

I replaced a swollen battery. It came with no charge. So, after about 2-3h, it was 100% charged. Watch works again! thanks

The guide looks incomplete to me. Adding a picture after pulling the battery connector out would help to understand better the last step. It took a while to figure this out. Also, links to the spare parts would be helpful.
