No major innovation compared to the Z1, but: Mobile very effective, always impeccable finishes

OK, the Z2 is clearly a very good mobile.

However, it does not bring any real revolution compared to char. his previous Sony model, the Z1.
I made a comment on the amazon Z (click on my username to view it), I was excited because he has made a very large range of novelty and innovation. The Z1 also has brought a lot of innovation in relation to Z.

But here, from Z1 to Z2 no major innovation hence the 4 stars instead of 5.

The only concrete news are taken from video in 4K (= 2 times the full HD) video editing achievable directly from the mobile (slowdown and acceleration of live video), and 5-pin jack socket that allows noise reduction.

For noise reduction, it is pretty good, but no need to test it in the subway to see the contribution it gives low: Although noise reduction is active and effective, you still keep your perception environment.
"Noise Reduction + Music" provides a sense of isolation pretty close to a listening "music only" without noise reduction.

Also, the battery was greatly improved capacity. The widely more than a day if the laptop is used very actively battery (application, mobile TV, music). I am not yet agreement at all once with the comment "Petit Nicolas" about it here because to burn the battery in less than a day, it is not the "intensive use" as said, but a very bad management and use of the product (= never pausing, never put in STAMINA mode that intelligently cut unnecessary standby wifi, never stop applications with the window of the latest applications, never turn off / turn on the mobile to release fragments of memory, etc ...).

IN SUMMARY:
- Phone super efficient, compared to Z1: improvement videos made on mobile + (5-pin audio jack instead of 4 which allows power from the Noise Reduction) + screen 5.2 "slightly larger than Z1.
- With always the same fundamental bases of Sony: waterproof, glass and aluminum materials pleasant.
- And basic technical capacity to upscale: 4G, full HD resolution, 20MP camera +.
- And finally useful finishes: 2 high front speakers to optimize the sound and an LED on the length of the upper HP, very classy.

The +: the noise reduction headphones MDR-NC31EM provided free in the box with the mobile (headphones values ​​on the SONY site if separately: 79.0), headphones with her happily-compatible technology with 5-pin jack the mobile.

All this makes him a true mobile without incredible innovation "breathtaking" but no doubt very effective, with impeccable finishes.

FOR WHO?
If you had the Xperia Z1, this mobile will have very little interest, unless you take a lot of video.
If you had the Xperia Z or an equivalent model, it's worth it if it is financially interesting for you (= beneficial mobile renewal, or just you can afford).
If you had a previous model and want to opt for a sustainable model, go with eyes closed.

If you are used to another brand other than Sony or another brand other than Sony + initially interested you, well the two mobile that compete directly with the Z2 are the HTC ONE M8 and the SAMSUNG GALAXY S5.

Each of these three high-end mobile have similar characteristics (such as components, power ... "what there is under the hood" and also the operating system Android 4.4), however, each has a mobile unique finish and different details.
This is according to your taste and preferences. I suggest you an easy and free grip in a shop operator (SFR, Orange etc ..) of each mobile set if you hesitate to buy one of these high-end mobile ...
