Re: 6 -> XS
Indeed, I'm very happy with my XS after upgrading from a 7.
My battery life is great, I used to plug in my phone every night but don't bother with the XS, knowing a little Car Play juicing on the commute will keep it chugging along nicely.
Since the XR came out however (and seems to be so good for £250 less than my XS) I was kicking myself a little bit for splashing out.
I think that the sheer size of the XR would have been too much for me though, the XS is pretty much as hefty as I want a phone to be.
So yeah, a XR would have been more than enough phone for my use, but I'm a happy XS customer.
