Yeah, those airjets are inefficient as hell. They need that increased battery size and then some alright. Here four mini airjets would consume 1W each at full load meaning 4W in total. That would absolutely tank the battery life hard under load and make it significantly worse at any load when they are on.

It's because of efficiency. It's a cool concept dont get me wrong, but compared to a fan you're using a lot more electricity for a little bit of airflow. Dave 2d just made a video covering this in depth.

Yup! Here's a graph:

It's probably for the usual reasons: Existing supply chains, lower costs for current solutions, and unwillingness to gamble on an emerging technology at scale. Companies are naturally risk averse and often take years to implement new standards, even if and when the new options are superior. These cooling solutions seem to be fairly low volume at the moment, meaning the time and difficulty to scale production would require significant investment, until which the fans are almost definitely going to be cheaper. Related to this, the availability of such fans is currently widespread - going through the costs of re-engineering your product for this new technology, adapting new production lines, and then hoping you can get a stable supply at sufficient scale to meet your needs is a tough pill to swallow.

12w to 18w power consumption... Green arrow up instead of red.

Samsung, we know that you treat your clients as if they were dumb, but that's just laughing at them a bit too much.

Edit: OK it seems that "Performance" is mislabeled in the graph and should read "Power Dissipation" (face-palm)
