Just as one example, Ankidroid is pretty unpleasant on a phone, especially searching for new decks. There are quite a few other apps, too, that are "tablet optimized" for larger screens than phones have, and use internal detection to change the UI/UX you're presented with. Web usage on sites that are menu or image heavy can be problematic, too, as is working with tabular data any time. I don't enjoy watching movies/tv on my phone, either (and the battery life is horrendous).
