Thank you, one and all. Maybe I am expecting too much of the Volvo stop/start system as the car is definitely doing fewer miles but does at least get driven regularly. 6 hours to fully charge? Then my 1hr there and 1 back wasn't enough it would seem.
All very strange as my BMW which has driven even fewer miles and sat stationary for long periods at a time seems to have a stop/start system that works just fine. It doesn't have its infotainment system shutting down when you listen to the DAB radio either.
Great cars these Volvos that seem to fail when challenged by the use they get from their owners......or maybe not.
