So far mine has been pretty good. I can't compare it to the Turbo 2. The battery is massive and using it the way I use a phone (not a power user) I could get two or three days out of it if I had to. I just went two days without charging it and still had 55% left when I put it on the charger.
Also of note is there is a Turbo charger and a usb cable in the box. It charges fast.
