Not really. Top of the line Android phones can actually be worse for this problem than cheaper ("burner") ones. Top-of-the-line Android phones tend to follow the pattern of having a CPU with many cores each of which is slower than the CPU would be if they used a single core solution. This is excellent for native apps that properly use multithreading, but dreadful for web apps since JavaScript as it is commonly written (ignoring the various *Worker extensions to the language attempted over the years) is essentially single-threaded, so the majority of the app code is running on one slow core while the rest sit idle (or run background services that have nothing to do with the foreground app).
