As they get older, a FItbit Aria scale can drain four AA batteries in a week. Batteries should last months. This is...

I have a Beko refrigerator. It is a European refrigerator, static cold, single compressor, freezer and refrigerator...

With further research, I found that the Aria has a poorly designed activation mechanism in the feet, with a plastic flex part that breaks, causing the activation contacts to randomly short, which keeps turning on the display. This happens repeatedly from any vibration or temperature change, and drains the batteries. The solution is to repair the flex part, possibly with glue or resin, or 3d print the replacement part from thingverse.

The foam on the connectors holds the connector in place once the phone is reassembled. The foam on the flex cable itself is normally a conductive pad that connects to the part that compresses it when reassembled. Sorry Ben, I have repaired computers, phones and tablets professionally, and have not heard of anyone cutting themselves on flex cables or flex cable connectors, with or without foam on them. You are more likely to be cut by paper than a flex cable.
