Xperia Z5 Premium does not display 4K all the time

xperia-z5-premium-4k

Since the release of the Xperia Z5 Premium there has been conversation about the 4K resolution not being rendered all the time. Now Sony has commented the debate.

At IFA 2015 Sony offered a very limited hands-on time with the Xperia Z5 Premium. Still some screenshots were taken and they revealed the fact that the UI is not rendered in 4K. This has launched a lot of discussion and now Sony has answered:

Xperia Z5 Premium features a 4K display with a resolution of 3840×2160 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.

It looks like the 4K is only used in Sony’s own photo and video apps and rest of the content is in 1080p. This reduces the load on the CPU and GPU and saves battery. The UI doesn’t need to be rendered in 4K, neither the web browser as we have all the responsive sites that display content ridiculously big anyways. The resolution downgrade makes sense until the point that many people use other apps to view content that would benefit from the 4K resolution.

We understand the reason behind this, battery life. What we don’t understand is the lack of customization. Why can’t the user choose how to stress the SoC and waste the battery. Sony already offers the great power saving tools that are customizable, why can’t the resolution downgrade be optional? Google Photos and YouTube should also take an advantage of the high resolution display.

In the Xperia UI, the user can choose which apps can use internet connection when the screen is turned off. It would be perfect if Sony could implement the same kind of settings to choose which apps can render in native 4K.

Sony Releases Three Xperia Z5 Models

Sony has just released three Xperia Z5 models, normal, Compact and the Premium with a 4K display. 

Sony started the Xperia Z5 keynote by talking about the camera. Sony sensors are not only used in Sony phones. Samsung and others have used Sony sensors for a while now and the new Xperia Z5 uses the latest version of the Exmor RS sensor. 23 megapixel camera also takes the image stabilization to the new level. The autofocus is Sony’s fastest yet with 30ms focusing. The camera should also be able to 5 times zoom in without loosing details and it should handle low light situations better. The front facing shooter is 5MP wide angle one and it can shoot 1080p video.

The most noticeable difference between the three model is the size. The Xperia Z5 has a 5.2″ 1080p display, the Z5 Compact packs a 4.6″ 720p display and the Premium model has a stunning 5.5″ 2160p 4K display with Sony’s 4K upscaling for sub-4K content. All the devices have the same 23 megapixel camera module, the side mounted fingerprint scanner and a two day battery life.

The Xperia Z5 has an octa-core Snapdragon 810 SoC with 3GB of RAM, 32GB of storage and a 2900mAh battery. The Z5 Premium packs a 3430mAh battery and the ridiculous 806 PPI 5.5″ 4K Triluminos display. The Compact model has only 2GB of RAM and a 2700mAh battery.

Sony hasn’t still been able to shrink down the bezels as all the models have the IP68 and IP65 certifications. The Z5 comes in 146 x 72 x 7.3mm and 154g, the Premium measures at 154.4 x 76.0 x 7.8mm and 180g and the Compact is smaller in 127 x 65 x 8.9mm and 138g.

The color lineups differ between the models. The Z5 comes in Graphite Black, Gold, White and Green. The Z5 Premium will be available in Chrome, Black and Gold and the Compact has color options of Graphite Black, Yellow, White and Coral.

All the models support the LTE Cat 6 networks and the usual Bluetooth 4.1, NFC,MHL, DLNA and WiFi MIMO. The new Xperias also support MicroSD cards up to 200GB.

Three Xperia Z5 Variants Leaked

Sony is apparently bringing its new flagship in three different screen sizes. The Xperia Z5 Premium will have a 4K display.

An unofficial Sony Georgia Facebook site has released the picture above with a text that reveals new information about the upcoming Sony flagships.

The original text is in Georgian but Evleaks has put it through Google Translate and found out that there’s some new information. By the looks of it, Sony will bring three variants of their next flagship instead of the usual two. With the normal sized and the Compact model there’s a new Premium model with bigger screen. The screen is not only larger but it has four times the pixels of the normal Z5. The Z5 is going to have a 5.2″ 1080p Full HD display and the Z5 Premium will have a 5.5″ 2160p 4K UHD display. Z5 Compact is going to have a 4.6″ 720p HD display.

The Facebook post also suggests a 23 megapixel camera with F1.8 aperture, OIS and super-fast focusing. As we already know from the previous leaks, the Z5 and the Z5 Compact will have a fingerprint scanner on the side and the post also confirms the same scanner in the Premium model. Previously there’s been leaks suggesting that the Z5 will have the Snapdragon 810 SoC and 3 or 4GB of RAM.

These leaks are very interesting. Sony was one of the firsts to put a 1080p display on a smartphone and now they are doing the same with 4K. The phones are presumably released next week and launched later. As usual, pricing and availability are a big question especially in the US. Sony doesn’t have very good record in bringing their devices to the States but hopefully they have figured it out. Personally I can say that if these leaks are true, the Premium model will most likely end up in my pocket as my daily driver.
