Not bad.. took 30 minutes.. Start to finish, and I worked slow and meticulously...
No left over parts, nothing broke or misplaced, and it WORKS !!
I am now a huge fan of the ifixit website. Directions were right on, and they even provide two Phillips screws to replace the Pentalobe screws that hold the display down to make it easier the next time..
Now lets see what it does to the battery performance..
I will post the results.. Ummmm.. can't take photos with the iPhone with it disassembled.. I will have to work on that..
Based on the current Battery performance, it can only get better, I hope. It does seem related to the iOS 11.3... and above battery management "features"...
And the garage remote is fixed.
