Sony has released the new family of Z5 smartphones, consisting of a Premium phablet with a 4K display, a normal and smaller smartphone and the Compact version, which is the smallest phone from this line. The Galaxy S6 edge Plus is the larger version of the first Samsung smartphone with a dual-edge display. So, which phablet do you prefer: the one that has a 4K display, or the other one with a screen which is curved on both sides?

Designs and Displays

The Xperia Z5 Premium inherited the OmniBalance style, but its edges are flatter and the fingerprint sensor is placed on the side power button. The metal frame combines perfectly with the glass backing, which comes in three variants of colors: Chrome, Black, Gold, but what needs to be mentioned is the IP68 certification, which makes the Z5 Premium resistant to dust and water. The device’s dimensions are 154.4 x 75.8 x 7.8 mm, it weights 180 grams and its 5.5-inch IPS LCD screen supports a 4K resolution, which translates to 2160 x 3840 pixels at 806 ppi. This means that the images are extremely sharp, but the colors are natural and when the users are watching videos, the deep blacks look perfect.

The Galaxy S6 edge+ has also a glass back, but its variants of colors are White Pearl, Black Sapphire, Gold Platinum and Green Emerald, and the metal frame runs around the curved screen which has a size of 5.7-inch and it uses the Super AMOLED technology, which makes the colors vibrant, oversaturated. The display is sharp enough with the 2K resolution of 1440 x 2560 pixels at 518 ppi, but what’s interesting about it is that it allows the users to set the left or right side of the screen as the active edge which is designated for specific actions, while the Edge Status bar shows you the things you want to check without waking the entire screen (notifications, alarms, clock etc.). The only protection that the Galaxy S6 Edge Plus benefits from is the Gorilla Glass 4, which is found on both panels, while the physical dimensions of the device are 154.4 x 75.8 x 6.9 mm and the weight is 153 grams.


The 23MP main camera of the Z5 Premium has the sensor at 1/2.3in and the aperture is f/2.0. Also, the focus is much faster, as it takes only 0.03 seconds to focus in normal conditions, and thanks to the new Super Resolution Technology, the camera gives up to 5x zoom. The 5.1MP front camera has six-element 24mm wide-angle lens which supports ISO up to 12800.

The Galaxy S6 Edge Plus offers a 16MP Sony IMX240 sensor which supports an aperture of f/1.9, 28mm, it has the sensor at 1/2.6in and the list of features includes Optical Image Stabilization, autofocus, LED flash, auto HDR and 4K video recording. The front camera is 5MP and supports an aperture of f/1.9, 22mm and 4K video capture. Samsung has optimized its camera software and it provides better results.


The Sony Xperia Z5 Premium is powered by the most powerful Qualcomm processor that has been released in 2015, Snapdragon 810, which has four cores clocked at 1.5GHz, while the other four cores run at 2GHz. The processor is backed by 3GB of RAM and the only variant of internal memory supports expansion from 32GB up to 200GB. The Galaxy S6 Edge Plus is speedier with its proprietary Exynos 7420 octa core processor consisting of a quad core processor clocked at 1.5GHz and a quad core processor which runs at 2.1GHz. The Galaxy S6 came with 3GB of RAM, but the Edge Plus version received an extra gig of RAM, for a better performance. The internal memory can’t be expanded, but it’s available in two variants of 32GB and 64GB.

The Xperia Z5 Premium has a larger battery of 3430mAh with Sony’s Stamina Mode for better endurance, while the 3000mAh battery of the Galaxy S6 Edge Plus supports wireless charging and it lasts an entire day under a normal use.
