Just changed battery on sisters 4S. Thanks to the many great comments and suggestions the change went smoothly and startup was flawless.
Boy are these screws tiny..!!
Tips that helped include: using #000 Phillips, working on white towel, egg cartoon parts holder, project light, iPhone magnifier on my 6S, toothpick to hold the two clips in place until I started the small lower screw, magnetized the screw drivers and tweezers, and plastic gloves to avoid contamination.
I still managed to dump the grounding clip onto the floor at one point but luckily found it.
Without the detailed procedures, photos and comments I would never have attempted this.
Thanks to all.
