For me, an iPhone is essentially a consumption and communication device. I can do everything I can do on the phone, faster and better on the laptop. Thus I find it is very valuable to give each of these devices a well defined purpose and use them in this way. With all the freedom and power that a smartphone brings, it also brings a lot of distraction. There is Twitter, Reddit, Instagram with their endless feeds of streaming live updating content. Reddit, Hacker News, Medium or any other news outlet you prefer to stay on top of news. Staying on top of everything at all times is exhausting and addictive.
