I do it short and sweet, I'm thrilled, albeit with restrictions. Particularly impressed by the madness of battery life, which for me is the killer feature per se, I come loose through the day, at 6 of the socket, the whole day on the road and evening even spontaneously until the wee hours at a party? No problem for the Z2, at last I do not have more worry when it comes to the shop, just as it should be. And I see myself in the trend rather than heavy users, 5-6 hours screen on time, with a lot of surfing on LTE and HSDPA, telen about 2 hours, no problem. In idle state, the Z2 hardly used is negligible namely electricity.
More Pros:
+ Processing, Design
+ Speed: really fast, I do not Mikroruckler etc.
Neutral:
- The camera: in lowlight in comparison to the competition very well, often blurred in daylight in automatic mode, do not like it so well, inexplicably, the manual mode with the local settings is often better by a mile!
- Screen, nothing earth-shattering, but absolutely ok.
Minus:
- 16GB storage for a Topsmartphone today absolutely no longer appropriate !! This is almost a deal breaker! From Android 4.4 data can also be more difficult to outsource ne external SD card, double annoying!
For my usage scenario due to the incredible battery power is currently the best mobile phone!
In one year, then there's the Z5 if Sony carries on at the pace ;-)
