I'm sure if they could offer better battery life, they would. But yes, obviously such efforts will involve some kind of optimization.
There are quadcopter drones out there which can purportedly last around an hour in the sky. The Aeryon drones for example, marketed for industrial applications, is touted to have up to almost an hour flight time. But the DJI Matrice 200 series, also for industrial applications, has around 1/2 an hour for example. So there are places where they can improve for sure. Surely it can't be a technology limitation.
not that hard in a fixed wing to get +10 minutes from optimizations like lighter body, larger wings, more aerodynamic and stuff like that because again the things generating lift does not require the battery to power it, its passive its the wings, the losses are from the drag of the air.
but with drones getting over the 30 minute hump is incredibly difficult not impossible, just currently impractical. have to consider batteries dont get lighter as they get drained so drawing same amperage at 100% and 10% battery but its alot harder for those battery cells to delivery same amps as gets weaker without voltage sag and heat from internal resistance, plus on top of that it has to deal with that weight of the drone still which more batteries = more weight = more work those batteries have to do.
people look at this like tesla cars i think who put more batteries in it and goes further, kinda true, however gravy isn't as big of an effect and drag coefficient isnt as still because the body of the car and speed of the vehicles.. where as with drone, gravy is always against you, and harder and faster have to spin those props the thicker and heavier air becomes..turns from being of little resistance to being like water or even honey depending how fast props are whipping around... and a tesla you can drive it slower if need to or battery is weak the motors and vehical works at whatever speeds you want.... drone has to keep the props spinning fast and hard or it falls like a stone..
as for the fan in mavic air,m doesnt draw much energy, the wires way to light and thin small gauge to carry much current. its loud because the fan is whipping air and being shoved down a blower style cooling system by some shielding thats why its so loud.... the blades arent really biting the air and throwing it a direction like a proper blower fan. i think yes they could optimize the SoC (system on Chip) a bit more so not as hot and doesnt draw as much power.. but i dont think the idel power useage of the mavic air is very high compared to drones like the spark, spark has really terrible idel power usage and by the time your airbourne with sat lock, you drained like 5-10% power...
