I check emails, I ePay, SMS/Discord messages, utility apps like hobby score tracking or taking notes, necessary company apps like airlines or resorts, etc.
I never use my phone for pleasure. If I look up a YouTube video, it's for a purpose and it ends at that purpose. If something takes me to a social media site, I read the post and end there.
I keep pleasure on my computer. When I step away from my computer, I'm disconnected from all the carcinogenics of the modern online life.
