Sony further clarifies why Xperia Z5 Premium mostly runs at 1080p despite 4K display
The Sony Xperia Z5 Premium is the first handset in the world to include a 4K display, and as we told in our hands-on coverage, it's a real joy to behold. But despite boasting an unholy number of pixels that comfortably trumps any other smartphone for density, there are quite a few caveats. As Sony mentioned shortly after the announcement of the Z5 Premium, the device only renders media in 4K, with the vast majority of the smartphone's experience set at a less extravagant 1080p. Noted at the time as a battery-saving measure, the Japanese firm has further clarified its stance on why the Xperia Z5 Premium's 4K display, for the most part, does not run at its native resolution. 

With a new 23-megapixel camera capable of 4K video, having a 4K display for viewing them can only enhance the user experience. However, Sony knows well that pushing an interface at 2160 x 3840 is going to wreak havoc with battery retention. While some may feel shortchanged that the 4K smartphone isn't always as sharp as it should be, Sony's explanation is a legitimate one:


Since most apps aren't built for 4K displays as yet, rendering applications and games in 4K mode would be a profligate use of resources:


The idea of future-proofing seems a noble enough cause, but one can't help wondering if this is a marketing ploy to set the Z5 Premium apart from the rest. Even to the average consumer, '4K' is an alluring buzzword, despite the fact that for the most part, users cannot make the most of it. 

After the stuttered arrival of the Xperia Z3+ and Z4, Sony needed a strong response, and on paper, the Z5 Premium is just that. But with its marquee feature being somewhat peripheral, early adopters may be waiting a long while to really make use of its capabilities.

If you are considering the purchase of an Xperia Z5 Premium, then the full article is well worth checking out at the source.

I'm almost positive that if you root your phone you can have it display 4k whenever you want, and Sony can also release updates that increase when you can use the 4k(Software updates from Sony... Okay I'm stretching...) for programs that have support for 4k. From the masses standpoint, this makes great sense. I do think an option to change it for users with the warning that battery life will be greatly sacrificed would be a great way to hush all of the haters and still keep the current set up.

In other words. it is really useless right now. Sure, specs junkies will still salivate.

1080p is good enough for media. 4k screen is just marketing stun and makes device overprice. No one is going to watch 4k video in smartphone. Maybe useful for pictures but it doesnt justify hefty price tag. Even my Z3 Compact 720p screen is good enough for me. I prefer 128GB internal storage, and bigger battery for Z5 premium rather than useless 4K screen.

Why are people bitching about a manufacturer taking money out of their own pocket to give us 4K and praising greedy companies that are keeping their displays at a s**t 750p for profit? You guys really need to work on your morals and societal beliefs....lol. Don't disempower technological advancement at reasonable prices and empower greedy cheap ass companies that hide poor hardware with simple software. They are giving you s**t 720p Z3 compact for battery and performance w***es, the Z5 to be safe from the haters, and the Z5 premium for not that much more, not even close to Apple prices for the people who demand the cutting edge. I would buy the premium in a heartbeat just to support them if it was the same size as the Z5. It's too big for me though. Lol

the thing is the cam on the + and the note 5 are better than the normal s6, I be thinking down to software or something, so they just need to test them and they will score better, I have both normal s6 edge and the bigger + ver and its 100% better both have the same Sony optics

That's easy. Snapdragon 810 has too weak GPU for 4K.

Nope its has all its need to Run 4K for the UI and normal app at least. for game thats may be another matter but for game no current SOC can run them at 4k anyway.

quite agree here. But... I don't think the UI speed will be stellar on UHD.

Who would want to see facebook, viber and tinder notifications in 4k anyway? Unless eagles and hawks know how to use phones, sony's approach on z5p display is not a deal breaker for me.

After Phonearena removed the article about Xperia Z5 DxOMark scores.www.phonearena.com/news/DxOMark-says-the-Sony-Xperia-Z5s-camera-is-the-best-its-tested-so-far_id74256 Now they are ignoring the most important thing that Sony conveyed in the article. "We also believe Xperia Z5 Premium is capable of offering the clearest, sharpest Virtual Reality platform – we’re working on a few things here internally, so stay tuned for more news soon."

Indeed, Virtual Reality is getting more and more attention, and this will be the best mobile device for VR. I really don't understand why PA is so bias against Sony.

you were born with human legs, so no need for cars you were born with human hands, so no need for forks ... 4k display on a phone of course is pretty much a "gimmick", according to many people, but it's also a first step for something better in the future just because you can't see it now doesnt mean it's useless for the rest of time

If Sony is very confident with their lines of Z5 phones and they want to enter the US market they should give their phones to Marques Brownlee and have him review their phones. He is one of the best reviewer and influential guy in the US.

to bad their marketing team is having a permanent vacation somewhere else =.= As much as i love Sony, I still have to admit their marketing strategy is a disaster

Lol the S810 isn't capable of rendering 4K content, so it isn't that futureproof.

Yes, and even the 801 was capable of 2560x2048

SD805 cannot handle WQHD properly even though it is theoretically capable of UHD.

Rendering picture and movie is a lots easier than UI and games.
