You can't have a game be free on one platform and cost money on another either, at least I am not aware of any such games. So either it is free/cheap everywhere or you don't release it on phones.
Edit: And by high budget games I mean games with a high development budget, not games that costs a lot to buy. Genshin impact is a AAA game that runs on phones, they invested $100 million to make it, that is what I meant by it being a high budget game.
My point is that the discussion wasn't around "high budget", it was around "high price". Yes Genshin Impact is high budget, but it's free everywhere so it's not relevant to the phenomenon of there effectively being a cap on game prices on phones.

It's not totally unheard of. Among Us is paid on PC/console but free on mobile. PUBG was similar before it went free to play on all platforms earlier this year.
