I've managed to limit my "phone time" significantly since a few years now. Other than the traditional remedies, one thing which works exceptionally well for me is that I've put the device on silent and on vibrate at all time, unless I'm explicitly expecting a very important call (rare). The main reasoning behind this is that auditory signals are much more distracting than visual signals; the latter you must explicitly look for. I just occasionally glance to check the flash notifier. The phone stays out of my hand most of the day.
