I myself don't mind sims using the phone a lot after the update but I understand why people find it annoying since there is no way to turn it down... The interaction should probably be user controlled, not added to the long list of idle animations that we already have in The Sims 4.
Idle animations are good for making sims seem less "robot-like" (otherwise they would just stand still) but they should probably not have so many phone animations as idle animations, idle animations play whenever the game thinks it has time to play them so it makes sims look obsessed with their phones, especially on a game that runs a bit slower.
For the next sims game phone interactions should probably be user controlled somehow, so that it feels that our sims have a choice to use the phone or not.
