Developers seem to keep trying to cram as much high-end technology into their phones as possible. Cell phones now rival televisions and cameras, as well as other devices, in many areas. You may have heard the term "4K" being tossed around in the past couple of years. For those not satisfied with 1080p resolution, 4K offers 4 times the pixel resolution. Sony's Xperia Z5 Premium is the first phone to offer a screen that boasts the ability to play back content in 4K; it also records video in the same resolution.
As for the camera, its sensor is a staggering 23 megapixels. For comparison, the Galaxy Note 5's camera is 16 megapixels while the iPhone 6's is only 8 megapixels.
Experts claim that specs at this level don't contribute enough value or function to the phone to justify their inclusion. Can the average consumer even process the contrast between these lofty specs with those of other phones? It all depends on the market for the phone.
Sony will be offering 2 other versions of the Xperia Z5, which are not as spec-heavy, which could suggest that Sony realizes the small market for super high-end phones. Apple has proven repeatedly that a phone doesn't require the highest specs to conquer the market. Even so, the feat of producing a phone with specs at the level of the Xperia Z5 Premium is impressive to say the least.
Sony’s Xperia Z5 will be available in October, with the premium version arriving in November. Pricing for the US is still not solidified.
