Hey. I want to buy a phone. My priorities are: camera >>>> performance >> battery

I found the Mi 11 refurbished (excellent condition) for that price which I thing is VERY good for a phone that was a flagship and the camera seems to be EXCELLENT.

Is there a better phone I can buy for that price? (Highest I can go is 250/300€) If possible, it should have custom ROM support (so probably Snapdragon cpu).

I live in Spain. I recommend looking at prices in kimovil.
