There has been plenty of buzz surrounding Sony’s splashy new entry to the Xperia Z5 family of phones. The Sony 4K Smartphone, known as the Xperia Z5 Premium, is said to be the first smartphone ever with a 4K display. It’s a revolutionary step forward visual quality on a handheld screen. However, as Engadget notes, there are a few details regarding the Sony 4K Smartphone that need to be taken into account.
The catch is this: Only videos and photos will display at 4K resolution on the vaunted Sony 4K Smartphone, whereas all other content will revert to 1080p. That means that we still haven’t reached the point of full 4K screen resolution. The hardware technology simply isn’t quite where it needs to be yet; according to Phone Arena, the decision was necessary in order for the phone to maintain its promised two-day battery life.
What is 4K resolution, you might ask? This refers to a display with horizontal resolution of 4,000 pixels. It is known as “ultra-high definition” and is a sizable step up from the current standard, 1080p HD. This TV resolution chart, courtesy of 4K.com, should give you an idea of the comparative quality:
Although the picture is a huge step up over 1080p, the processing power needed to render 4K resolution is substantial. It will drain a laptop battery quickly, so it goes without saying that a smaller cell phone battery is going to struggle to survive while constantly running it. This explains why the Sony 4K Smartphone needed to wade into this pool rather than diving in.
It’s still a major innovation in the smartphone game, and we’re excited to experience photos and video at 4K resolution on the new Xperia Z5 Premium device. Packing 8 million pixes into a 5.5-inch display, it represents a new frontier for viewing media on the mobile screen.
