Battery was draining too quickly and battery indicator was dropping from 30% to LOW Battery Message.
This was my second time performing a battery replacement and it went much faster. Purchased the iSclack this time around and it worked like a charm, but not necessary for the repair.
Removing the battery adhesive continues to be the most challenging aspect since I seem to stretch it to a breaking point going around the battery. I found it easier to pull it straight out without going around the battery. I can see myself doing future battery replacements and will purchase the Magnetic Mat to keep track of the parts especially the tiny screws. The mat will help with organization and keep track of the of the steps for reassembly.
