Having tried to do a lot on smartphones, I'd say I have given up most of them. Editing texts on a touch screen is quite miserable for me, and I get thumb cramp after sending a lot of texts. Speech-to-text is great, but I still have to edit a lot, especially when what I talk about isn't pure English. I now carry a notepad and pen with me. One thing that can be done effectively is recording. Whether it's recording a video or audio, modern smart phone is better than cameras in terms of usability. I don't edit on the phone though. It's still too small a screen to be comfortable. I also want to point out that not all consumption is unproductive. If you are reading/watching videos critically, it's a very enriching experience. You can learn a new recipe, analyze some music, etc. Reading emails, sending important texts, making reservations, etc., especially if you are going to do it at some point anyway, are also productive.
