Sony Xperia Z5 Premium hands-on: the first phone with a 4K screen

It was bound to happen sooner or later – the world's first smartphone boasting a 4K display has been officially announced. That's the Sony Xperia Z5 Premium, which got unveiled at IFA 2015. Long story short, we're dealing with a cool yet weird beast of a smartphone – a smartphone reminding us that technology still has plenty of room ahead of it to evolve. After all, a figure of 800 pixels per inch sound quite impressive, no matter how we look at it. On the other hand, the Z5 Premium raises the question whether a 4K screen on a smartphone is truly something we need or simply a gimmick. Let's dive into it, shall we?...

Wait. The Meizu M5 with the SD820 is supposed to come out February at the latest so better devices are literally right around the corner.

There are no advantages to USB Type C, right now, in fact, more disadvantages than advantages, quite frankly. It does not charge the phone any faster, is less versatile! Feel free to enlighten me.....I am sure there will be a time when there are clear advantages to be had but there are none save, for it being reversible, right now.

Sony claims up to 2 days battery life even for the z5 premium. We just have to wait for reviews.

O.k we were glad Apple joined the Mobile Market but there Pricing of there Phones as got the Others thinking if Apple can get away with Over Pricing Why Can"t We,£699 sim free is way over the Top for a Smartphone that might Overheat,people would spend this money Smart Tv instead of phone in your hand

Might....well, if my auntie had balls she'd be my uncle....! Go read GSMArena, Sony has addressed potential for the SD810 to heat up through the installation of 2 cooling pipes within the phone.......crazy cool. There is tear down of the phone on GSMA.

Hopefully people stop complaining about 4k screens. Like it or not, they are here and they really don't affect performance and battery all that much. In fact, the diminishing returns of battery and performance is similar to the diminishing resolution difference. Just look at the Z3 vs the Z3 compact. Despite what the benchmarks say, that are rigged for Apples low res screens, the performance and battery is pretty damn close. And I predict that the Z5 premium won't be noticeably worse than the Z5 in performance and battery either. So let the manufacturers that pour billions into new technologies worry about what's overkill and what's not.

Are you kidding? 4k is almost 4 times of pixels of FHD and QHD is almost twice of FHD, if QHD S6 is about 80 percent of HTC m9 in fps. So if we do rough count don't expect more than half of fps of htc m9 or sony z3+

What? You can't do your count yourself? I said roughly. you can't hope 70-80 percent range of graphic performance of SD 810 with FHD.

Um the GS6 performs better than the M9 in most cases. In fact, the GTA3 is probably the only game that runs better on the Adreno 430. Dragon quest and other games that chug on most phones actually run better on the GS6. Like I said, whatever the benchmarks say, there's really no noticeable difference. The Xperia Z3 compact and and Z3 perform roughly the same in battery and performance despite the huge resolution gap.

Hm, wouldn't this heat up so much because that 810 + 4K combo?

85. TMach unregistered

See link below. Records 10 mins of 4K content without heating up which absolutely no other phone manages!

90% chance Z5 Premium will be my next phone. I just don't see anything else available before the end of the year that can match this. I was planning on buying the large Nexus 7 until I saw how absolutely ugly it is with that huge hump on the back. The only other interesting phone coming soon is the BlackBerry Venice.

"As a matter of fact, we could probably stick our nose to its surface and still find it hard to spot individual pixels." Is this the way of evaluating top of the line screens?

How is this better than note 5 or the s6 edge?

Just one thing please market the hell out of these phones. Marketing has always been Sony's achilles heel...Emphasise all of your products USPs! Gonna grab me a Z5 Premium.

The author seems unaware of HMD based mobile cinema or virtual reality in his consideration of the display resolution. 2160 lines is about the lowest with which you can begin to expect cinema quality video from a head mounted display. That's what the bulk of that potential market requires and that's why it will be the new standard for anything that can call itself premium.

Sony still use snap 810. is it still hot like an iron when we play game or use camera as z3+ ?
