A Tesla battery will take a 3,000 pound car a couple hundred miles or so. To take a hundred thousand pound aircraft to 30,000 feet and a few hours of flight or more requires a huge (heavy) amount of battery power/weight.
Also the ability to recharge or relace the cells for a rather quick turnaround is required. The fact that fuel burn and weight loss makes an aircraft more economic over time is lost on battery powered aircraft as well.
And short sighted people never make leaps and bounds.
Although Tesla had the idea of wireless transfer of power on a large magnitude 100ish years ago - he never thought of supplying 10 GW (Many, many, many houses) base load solar power from space 36,000 km away.
A) they will be different batteries than that of now.
B) the take off (launch) of aircraft may be very different - zero power consumed till after take off, dodgem cars or catapult launch or some new thing.
C) The ability to recharge or replace the cells may not be required - they may just be the emergency back up.
D) If your batteries/cells are only back up and are lighter than current fuel burnt to carry such reserve & its weight, fuel then becomes the economic problem to be carried prior to take off in comparison.
F) the phone was a tech advancement example not a power consumption one.
The Japanese a number of years ago now transferred wireless power, enough to boil a kettle with accuracy over 55 meters. That I assume charges a few phones.
