This is exactly it. The tech in these sorts of devices is way overpowered for what they are or need simply because it's a lot cheaper to do it that way than it would be to use more appropriately scaled computing power. Either the "more appropriate" components are no longer in production, or they are in production but are now considered somewhat niche and are only produced in volumes that make them considerably more expensive than the more advanced/powerful options.

So you end up with something that could probably be coaxed into running DOOM at playable FPS (if it had enough RAM and a display) relegated to running a humble - and frankly objectionably wasteful (coupled with questionable health outcomes with long term use) - disposable vape.
