I have 2 Nest Learning thermostat. I think it’s version 3. They are both 6 years old. The one I have in the downstairs no longer connects to WiFi and loses charge. I’ve never had to charge it before. If I pull it out and charge it manually, it will connect for a little while and within a day says offline and a low battery again.

Could this be a Thermostat issue? Would the system stop charging the thermostat after 6 years?
