* Keeping in touch with people - texting, calling, social media apps like FB, Twitter, WhatsApp, Line, etc. (the most important aspect of the phone imo)
* Listening to music (the most used app in terms of hours spent. Thank goodness Music app doesn't consume battery much)
* Reading news (movie industry news, car news, general news, forums like MacRumors, etc)
* Work-related apps (cloud storage apps, word-processing app, PDF, scanning documents, etc)
* Weather (I'm sensitive about what I wear and my car, so I check weather multiple times each day)
* Movie streaming apps (Mubi, Fandor, Shomi, YouTube, etc)
* Guitar tab reader
* Reading books (I use iBouquiniste)
* Reading emails.
* Calendar app and date-based Reminders
* Shopping (imagine going back in time to 10 years ago to tell people that we will be doing shopping on the phone....)
