should I replace my phone with an Nokia E72 or samsung e250?

I want to be more productive in life and I feel like I'm stuck with my stupid phone and waste my hours with it and I want to change it in a way. I tried to limit the use of apps in my phone but at the end nothing really happend so I'm thinking about using old phones as an escape from all of it and I still like the function and the look of it. It is pleasing to me.

In short I want to limit the use of my phone in my life and focus on life and college and actually be productive about it. what should I do? which model is better for me?
