You touch these often, yes, but how often do you share them with other people? If all the germs on there are yours, maybe disinfecting it is not really helping.
But if you are constantly handling your phone it will reduce the value of frequent washing/sanitizing of hands, since anything you do get on your hands will transfer to your phone.
Although, I don’t know what the numbers look like for transferring virus when a touch occurs—e.g. if we look at a path like “handshake → touch phone → [wash hands] → touch phone → touch face”, how much of the virus is left after four sequential touch events like that? Perhaps this kind of secondary contamination is not actually a huge deal? I have no idea.
A powder called Glo Germ, meant to visualize germ spread, was still visible to the naked eye after 8 handshakes (but not 9) in an informal experiment by YouTuber Mark Rober. ( https://youtu.be/I5-dI74zxPg?t=346 )
This is my usual attitude, but given the evidence that coronavirus is very long lived on surfaces and reinfection is possible, it seems worth it to me in this specific case.

I guesstimate the deal is not negligible.
