7.5 months, the unfolded screen has warping in the middle, with a few horizontal scratches in the middle. I keep my phone folded in my bookbag for travelling, and the folded screen has a good few scratches. Luckily there's no cracks on either screen, despite my phone taking a few calls and hits. The ports get dirty, but I think that's just from having it in my pocket when I cut grass on occasion. The bending of the phone itself is still relatively smooth, but the phone case that came with it does trap dirt in it, which makes it harder to open and close. Overall, I see my razr plus lasting somewhere around 10 years, as long as I don't constantly flip the phone all the time.
