Sony Xperia Z5 Premium pushes the world’s first 4K resolution smart phone


The display is the most looked at component on a smart phone, and Sony’s latest and greatest has broken all conventions with the new Xperia Z5 Premium. It packs a 4K display at the front which is basically 3840×2160 pixels crammed into a 5.5″ screen, giving an insane pixel density of 806 pixels per inch. If you can’t imagine how big a deal this is, it is like squeezing 4x Full HD displays into a single smart phone.

This a huge leap not only for Sony but also for the smart phone industry where most players are still reluctant to jump onto the Quad HD bandwagon due to power and cost practicality.

With a display allowing you to watch 4K content in its intended resolution, the Xperia Z5 Premium also gets a newer 23MP 1/2.3″ Exmor RS sensor with a f/2.0 lens. This is a fully upgraded camera since the Xperia Z1 that came with a 20.7MP shooter until its recent Xperia Z3+. It records 4K videos and despite having no Optical Image Stabilisation, the Inteligent Active Steady Shot technology helps to remove unintended shakes from your footages. With a Hybrid AutoFocus system that first featured on the Xperia M5, you can capture moments quicker with its 0.03 second focus time. For the front, it gets a 5MP camera that could also record Full HD videos.


Under the hood, it gets the same Qualcomm Snapdragon 810 processor as the rest of the Xperia Z5 series and it is mated to 3GB of RAM along with 32GB of on-board storage. Being a 4K consuming and creating device, it allows storage expansion with microSD up to 200GB.

In the audio department, the Xperia Z5 Premium has no compromises with its High-Res Audio support, DSEE HX upscaling and built-in Digital Noise Cancellation. For better audio playback, it gets an S-Force Front Surround speakers and it also records audio in stereo format.

Even with such a high resolution display, the Xperia Z5 Premium still maintain’s Sony’s phenomenal up to 2 days of battery life thanks to a much larger 3,430mAh capacity battery. The long battery life is achieved with a built-in memory on the display which cuts down processor utilisation when the screen isn’t refreshed. To juice up faster, it supports QuickCharge 2.0 that could give you 5.5 hours of use with just a 10 minute charge.


In terms of design, it is slightly thicker at 7.8mm and it weighs 180 grams. On the right side, the iconic physical power button has been replaced with a capacitive unit which doubles up as a one touch fingerprint scanner. To live up to its Premium name, the device comes with a stainless steel frame and it comes with a mirror finish Black, Gold and Chrome colours. As always, the Xperia Z5 Premium is also water and dust resistant with a capless micro USB charging port with IP68 rating. In terms of availability, the Xperia Z5 Premium will be available from November 2015 and it comes in both Single and Dual SIM variants.
