Nest was recently turned on for the season. It started needing to be charged once a day in order to function for a few hours. All wires connected properly. Furnace repair speculates that it is not connecting properly to the base.
Now it is barely holding a charge and requires heat turned up to 90 degrees plus (in freezing house) to turn on briefly. I now think it is overheating on usb power.
Product is about 5 years old max. Appreciate the help!
