Sony Z5 Premium with 5.5" 4K display !

[spriter]

BTW, QHD displays DID NOT decrease battery life, the Note 4, LG G3, Nexus 6, Droid Turbo etc... All gave great battery life vs. their HD1080P predecessors.

Where in my post did I say resolution has zero impact on battery life, really annoys me when someone gets ridiculous when we are trying to have a decent debate.

"QHD displays DID NOT decrease battery life" sounds fairly incriminating.

Regardless, it matters not what I think. Let's see what a larger, more experienced organisation has to say about it... The horse's mouth:

Xperia Z5 Premium features a 4K display with a resolution of 3840x2160 pixels based on SID Standard and enables all video and image content to be enjoyed in 4K resolution. All other content is displayed at 1080P or lower resolution in order to optimise the performance and battery stamina for this device, ensuring you can enjoy the 4K resolution when you need it most.

So yeah, I'm going to go with Sony on this one .

Sorry, but it aint that easy.

Lets just be honest here, if there was a SoC that could handle 4K efficiently the Z5P would run 4K constantly. The Snapdragon 810 CPU that is found in the Z5 series has reputation for overheating, so Sony found a way to implement a 4K display while using the only SoC readily available to them that can at least do 4K content. They didn't want to find themselves in the situation LG did with the G3 last year where they put a 2K display with a SoC not optimised to run a 2K UI efficiently.

As I said before, there is a lot more to this, not just res.

You need an efficient panel, a SoC built to handle that res efficiently and so on.

GSMArena:

A 5.5 inch UHD display is a wild concept on Sony's part, but the OEM had to be careful not to go overboard with it. The pixels might be there, but the Snapdragon 810 chip inside the device and particularly its Adreno 430 GPU aren't really designed to constantly work
to push out such a huge resolution. While the silicon is capable enough of rendering the content, doing it all the time will undoubtedly lead to overheating and a major strain on the battery.

The Snapdragon 810 is not built to run a 4k mobile display.

Best believe once the SoCs that can run 4K UI arrive many of the OEMs incl. Sony will let the phones run 4K all the time. Sony wanted to get the jump on 4K Displays in mobile, and they did it in a fantastic way.

I've seen alot of Pointless things in my day but a 5.5" inch display yes Five Inches and 4K resolution is the definition of pointless.

Outside of VR applications, completely agree.

...Sony is no different than the failing HTC these days, just more established and diversified. Tim Cook has nothing to worry about. Samsung and Google? Maybe a little. Sony? LOL! Hell no. Like Nokia, Sony's best days are behind them. Just some blind loyalty and nostalgia distorts reality here. Sony overcharges from reputation, not quality. LG, Xiaomi, Meizu, ZTE, ASUS Gionee/BLU, and Oppo/OnePlus, those are future brands to watch for. All of them are already offering better price points and even surpassing Sony in features and design. Sony is part of a mobile club consisting of Nokia, Motorola, HTC, and BlackBerry. The has-beens club although Sony probably never reached the marketshare that Nokia, Motorola, and RIM once had.

Something else also distorts reality here...

for YOU

Anyone who uses VR will appreciate this.

We could go on all day about things you and me find pointless in mobile, but others would want. E.g. Music Streaming for me is pointless due to the crazy rates the mobile networks charge here.

Lets just be honest here, if there was a SoC that could handle 4K efficiently the Z5P would run 4K constantly.

On the contrary, if it switches to 4k when playing video one might argue the 810 SoC is perfectly capable of operating at 4k. That it doesn't is a choice Sony as made to preserve battery given 4k home screens are less beneficial than user-acceptable battery life.

As I said before, there is a lot more to this, not just res.

Adding variables to supplement your argument isn't going to cut it. Go back to scientific theory and know that the only variable that should change in a fair test of battery longevity would be resolution (again, see Oppo Find 7 vs Oppo Find 7a). Clearly, adding in a more powerful SoC to power a higher resolution is only going to skew the battery data and misinform results.

You need an efficient panel, a SoC built to handle that res efficiently and so on.

So you're conclusion has clauses: resolution doesn't affect battery life so long as there other bits thrown into the mix to make it so. OK then. I'd simply say it does.

I've seen alot of Pointless things in my day but a 5.5" inch display yes Five Inches and 4K resolution is the definition of pointless.

Maybe, and it wouldn't be the first less-adopted tech development we've seen. But that's the beauty of tech. Gotta keep pushing the envelope. Anyway, why not wait and see for yourself...?

What bothers me is that Sony phones aren't exactly famed for their screens. Everyone knows Samsung are leap and bounds ahead of everyone else in this department. On that basis, I have little reason to believe that Sony's 4K screen is going to be any better than the one on the Note 5/Edge+.

Prove me wrong Sony, prove me wrong.

The Snapdragon 810 proved to be a problem in running a HD1080P UI in:

LG G Flex2
Htc One M9
Xperia Z3+/Z4
And a number of other flagships, that is a crystal clear indication that running a 4K UI would be disastrous with that SoC.

You seem to forget that playing e.g. 4K vids is less demanding than running a whole UI in 4K. Android ramps up the CPU clock when you touch the screen, so e.g. web browsing, gaming etc... Would cause the Snapdragon 810 to overheat and throttle heavily if the whole UI was 4K, whereas when playing a video you have the GPU and CPU running the load at lower more manageable clocks as there is less interaction with the UI, and the load is generally well balanced out.

Yes, running a higher res requires a number of things to be done well,Samsung prove it time and time again. As much as I hate to admit, the Note 5 and S6 Edge+ with smaller batteries than the Note 4 manage equal battery life, why? This is due to them using an even better and far more efficient SoC, the 14nm Exynos7420. They manage to beat every Snapdragon 810 phone that runs a smaller display at HD1080P, that my friend is clear proof, that res is not the only factor.

Sony burnt themselves with the 810 the 1st time around, and had to do two things:

Differentiate (4k)
And Fix what went wrong (all kinds of heat dissipation solutions in Z5 series)

This forced them to run the Z5P the way they have. If the Snapdragon 820 proves to be capable of running 4K best believe Samsung and LG will jump on it and point out that Sony don't truly run 4K in the Z5P all the time, but the Galaxy Sx does and still manages X battery life.

As a galaxy vr user I can't wait for 5.1 4k on the gs7 and other then vr its a waste.
