what is the best under 300 dollar phone that can run warzone mobile?

Increase your budget and get Poco F6. Believe me, you'll need a lot of performance later on in the future.

don't play that shit

nubia 9 pro I think 🤔

iPhone 13 pro Max

there is a good amount I think, you just need to catch them at sale. there is also lots of youtube videos listing gaming phones under 300$.

Poco X6 pro is priced at 310$ with 8Ram-256GBs, I have the 12+6Ram-512GB, honestly an amazing experience, I played genshin impact on maximum graphic settings and it was SMOOTH, I'd recommend you to invest in the one I bought, I got it for 350$, I know you wanted under 300, but for the value this is the best phone bruv

I can run it perfectly on my Poco F6. 12 GB Ram, 512 GB Memory and the Snapdragon is Gen3 deliver a perfect gaming experience. I paid just 350 Euro for my unit and I'm very happy with it!
