There is no percentage setting for Return to Home.

Yes there is.if you go to the battery settings it gives you option to set your rth percentage

Sparky: you seem to be confused. You can set battery level warnings but not a percentage for RTH. There is a switch to enable ‘Smart RTH’, this means the Spark will commence RTH when it calculates battery power required to safely get home. Hence why you see a moving ‘H’ on the battery indicator. The RTH will be initiated based on distance, height, wind - so every flight, it could be different. Screenshot from DJI GO4 (currently disconnected but shows the setting I mention).

As Mike mentions above and as I stated - There is no RTH percentage level adjustment.
RTH is dynamic and will adjust itself based on the distance the aircraft is from the Home Point. There is no user control over this.
Familiarise yourself with pages 13/14/15 of the user manual.

Thanks for your reply.
The reason I said this, I was flying for about 10min and a message poped up saying rth will kick in unless I cancel. And when I went to battery screen I saw it was set on 22%.
