Sony has just announced the Xperia Z2, which is the direct successor to the Xperia Z1 that released in the fall. While quite a bit stays the same, there’s also quite a bit that has changed.
While there’s plenty of other things mentioned in the press release, much of it is the standard fluff and fanfare that most press releases come with. Ultimately, the differences come down to the spec sheet, and the Xperia Z2 has few notable changes from the Xperia Z1. Battery gets larger to compensate for the larger display, Sony added the ability to record in 4K/30p, the SoC is a minor bump from improved yields, RAM goes up to compete with Samsung’s Note 3 and presumably a future Galaxy S phone as well.
While I will admit that I haven’t properly used either Xperia Z1/Z2, I do have a good idea of the various issues that seem to be consistently repeated by Sony in their Xperia lineup. Probably the biggest question that I have is whether the Xperia Z2 truly has a better display than the Xperia Z1. While the press release talks about how “TRILUMINOS Display for mobile with brand new Live Colour LED uses red & green phosphor with blue LEDs and customised colour filters to produce a brighter and more uniform light. The result is richer colours on the screen for all of your smartphone viewing without the risk of saturation,” I am skeptical that this actually translates to better display. While it’s too early to judge whether display has truly changed from the Z1’s display with poor calibration and worse viewing angles, initially it seems that nothing significant has changed.
What can be talked about is the MSM8974AB, a SoC that was already outed by Xiaomi with their Mi-3. The differences are minor, far smaller than that of the APQ8064 and APQ8064AB/AC, which had slightly improved IPC and higher clocks. The 8974AB instead brings higher GPU clocks (550 MHz vs 450 MHz), higher memory clocks (933 MHz vs 800 MHz), and the ISP goes from 320 MHz to 465 MHz. This is almost guaranteed to be the SoC of choice for all high end flagships launching at MWC, judging by various rumblings about the internet.
The final change of note in the Xperia Z2 are the stereo front facing speakers, which are finally in a phone that doesn’t start with One or Butterfly in the model name. While there aren’t many details on the quality of the speakers, just putting them on the front is great. However, just like with HTC devices, it seems that the speakers have added a great deal of bezel to the front of the device. While some may not mind the difference, there are definitely a great deal of people that voice their complaints over the size of bezels in phones.
Outside of hardware, it should be noted that Sony is advertising a “built-in noise cancelation feature with certain earbuds. These would use two microphones located on the earbuds and leverage the smartphone for the noise cancelation processing.
