Cell phone are becoming increasingly popular with people from every walk of life as they become less and less expensive and installed with more and more practical built-in functions.



Is the above text well constructed? If not, how would you revise it? Thanks.

In this sentence I'd omit less and less, more and more and find some adverb to stress what you mean. my advice is
much more practical
they gradually become not that much expensive
