As long as we all don't know how exactly these "SOC" figures are derived, we're probably better off if we just ignore them. In the case of
@PBD I assume they have installed a (relatively...) new & full battery, and, most importantly, have reset the the SOC-status. Something that should be possible by the user in such a vehicle. As long as we as the users don't have access to a decent diagnostic tool and a complete workshop manual, it all remains speculation.
It is hard enough to determine the SOC of a lead acid battery even with advanced methods, (EDIT: Google "soc determination of lead acid batteries") I strongly doubt that INEOS have implemented something appropriate (Please, INEOS: Prove me wrong anytime by sharing detailed information!!). A displayed 1% resolution is also, let's say, optimistic...
_If_ something like Coloumb-counting would be implemented (there seem to be current measurement devices present at the battery poles, irritatingly 2 of them at the starter battery, in both + and -), when charging the battery with an external charger when ignition is off does not change SOC figures, since the charge cannot be measured & accumulated.
I would really appreciate more information.
Have ~5000kms now, no SW update, and every km proves that the decision to buy that toy was _absolutely_right_
