As far as I know, this performance started in 1.20, it consists of simply as we walk, it drops the fps from 90 to 30, to render the chunks.
It's a game performance error, not my phone's, because regardless of the number of chunks, it still has this problem, There are many performance issues in Minecraft Bedrock, this is one of them, It's an error that goes unnoticed, but I think it's due to a lack of optimization for the new versions of android
