Yes.That will mean at least one of your media, interior then exterior lights will be switched off. In the end the onboard computer will tell you to switch on the engine or it will shut down the electrics.
As you say, I think what points to a bad battery is the lack of any of the above-- also the fact that I have stressed my battery but never got this issue after-- I even updated the software and GPS without connecting a charger loads of times working with the car with the ignition on (=headlights on)
I also think very little to be gained from looking at the induced (computed) values, as this is probably pre-mature failure according to the calculations. I believe @Ape_Factory was looking at the chart showing the charging, not sure where that is located. I believe with the regeneration when coasting and the higher voltage, the battery should charge quickly, meaning if the battery is healthy it should not need to charge much when idling.
