With the Sony Xperia Z3 having failed to follow the LG G3 down the QHD display route, Sony has suggested adding a 2K screen to a phone is not worth the hit to battery life.

While some have been left disappointed by the iterative updates made to the newly confirmed Xperia Z3 over the Xperia Z2, Sony has claimed the omission of a 2K display is actually a benefit to consumers.

“Perhaps the most important thing to say about the screen is what we haven’t done,” Calum MacDougall, Sony’s Director of Xperia Marketing said speaking to TrustedReviews. “What we haven’t done is make it a 2K screen.

“ We have made the decision to continue with a Full HD, 1080p screen for the Xperia Z3, although we see in the marketplace some of our competitors bringing in 2K screens. ”

With the damaging affects to battery life the primary reason for this lack of technical progressions, MacDougall has suggested there are further thoughts behind not making the move to a 2K screen.

“Why have we made that decision? Well, there are three important reasons,” he told us.

“Firstly, if we think of this size of screen, even up to 8-inches, they are relatively small screens and it is very difficult for the human eye to discern the difference between 2K and Full HD.

“Thinking again about user-motivated innovation, we see from the user experience point of view that the differences are minimal, particularly if you add on top our Sony TV technologies which are reason number two.”

He added: “We have brought into the screen, as before, a Triluminous display for mobile which widens the colour gamut, X-Reality for mobile which is the equivalent of DSEHX for TV – it up-rates your pictures – and this gives us a 600 candela screen, a really bright, vivid screen with IPS that works in direct sunlight without having to implement a 2K screen.”

Finally, battery life is the key. With the Xperia Z3, Sony has managed to extend the staying power of its flagship phone to two days, a key benefit over rival devices.

“The final point goes back to battery consumption,” MacDougall said.

“If we believe that a key part of the user experience for consumers is to have a longer term battery, and if we believe we can deliver a great screen with Full HD and our Sony technologies, we don’t believe the trade-off between having a 2K screen and battery consumption is the right trade-off for a consumer.”
