Your analogy doesn't fit the different markets, since,
mobile phones (the precursors to smartphones), never had to worry about fitting the wishes of the environmental wacko agenda, while, EVs are an attempt to replace the fossil fuel powered vehicles, with an agenda item by the wacky environmentalists.
Besides, the electric vehicles have been around for more than 100 years, and the makers/designers have been trying, for most of that time, to make them energy-efficient while trying to add distance to a charge. They've failed in every attempt, and they've given up many times in the past, and, just like Audi, they'll be giving up again. The technology is not there yet, and may never be, while, when it comes to the technology in computers and mobile devices (like smartphones), is one which is very doable and still getting improved on. By the time EVs become energy efficient, and can actually compete with fossil fuels, we'll be getting around with jet-packs, which might mean, never.
