I have a T460p and I'm very happy with it. I can't give you a precise battery life but I've stopped plugging my laptop in when I'm using it outside the house.

I have a T460p and I'm very happy with it. I can't give you a precise battery life but I've stopped plugging my laptop in when I'm using it outside the house. The only problems I've had have had to do with running Linux with a high DPI screen.
