Would anyone go for the z play over the z2 play? Not an upgrade from the first z play but a new phone
I would make a case for the Z2. The Z has 16% more battery, but the Z2 life is still excellent. it like the difference between excellent (Z2 Play) and best ever (Z Play). Excellent is still, well, excellent. Probably the difference between 40 hours of average use (Z2) vs. 48 hours of average use (Z).
The Z2 Play has:
-better camera
-metal back (vs glass)
-slightly faster CPU clock
-upgraded Bluetooth
-more likely to get Android O
-FM radio
-better finger print scanner with nav features
On the other hand, the original Z does go a bit longer on battery and it can be found for a $50 discount relative to the Z2 Play. I would go for the new Z2, if only for the camera and software updates.
