The default of phone screens sleeping if they aren't touched every couple of seconds I believe contributes a lot to their addictive behaviour. Using a phone as a device to enable thinking (like a book) involves taking in information from the device and then processing that information internally. The fact that phones by default sleep/dim after several seconds continously beheads the second part of that process. You have to stop processing and think about tapping your phone to wake it back up.
