I really recommend trying an e-reader in your local shop or borrowing one from a friend if you can.
I’ve read books on my phone for about a year now, but the “feeling” isn’t right there, and I somehow get distracted a bit.
I’m really a fan of “a device should do one thing, and that really good”. I bought a camera, a reader, and so on because of that. My software habits are the same. I have dozens of simple apps on my phone and PC, and all of them serve one single purpose. Look up the UNIX-principle if you’re interested in more. (Sorry, this site is full of Linux-circlejerk 🙃)
The camera makes 10x better photos than every top tier smartphone (+ is a fun offline hobby that improves your skills!)
The reader gives you a display that’s super easy on the eyes, lasts for weeks on battery and doesn’t distract you.
My smartphone is only there for communication (Lemmy, messengers, calls) or if I have to quickly look up something on the web
Separating everything really also separates your mind, giving you peace.
