The best feature on a mobile phone is the one that makes it less of a mobile phone – The Airplane Mode.
Use Airplane mode frequently.
This helps reduce distractions while engaging in deep work.
Use it while sitting in a cafe and working.
Use it while sleeping to protect your brain.
Use it while practicing the pomodoro technique work session.
I found this the most easily available productivity tool and I use it a lot for big blocks of focused deep work, especially where I don’t have to be coordinating with others.
This is great for working on a business strategy, or reviewing some data reports, or reading a book to upgrade my skills.
For example, I have a habit trigger when I open any PDF to read or review, I will first switch off all notifications by going airplane mode so I can focus on the PDF.
