You call it silly because you could be doing useful stuff on your phone. I'd go one step further and say that even if you're slacking off that's not necessarily a bad thing. Everybody, including politicians, slacks off from time to time. Be it due to stress, awful sleep because the neighbor's dog barked all night, illness, or something else. It's just human and there's little wrong with it as long as you do your job well most of the time.
