Sony confirms what we’ve known about Xperia Z5 Premium’s 4K display

There has been much ado about the Sony Xperia Z5 Premium’s 4K display – the only 4K display on a smartphone out in the market today. What does it do? What does it not do? A lot of techie consumers are concerned about the battery impact of such a high pixel density screen. Well, fret you not – Sony is answering your questions, but it’s not anything you haven’t thought about before.

First up – what does it do and not do? As far as Sony is willing to say, the 4K display is only used to its full resolution on a few occasions – including viewing 4K content that you recorded on the device with the 4K-capable camera of the Xperia Z5, or when playing 4K content from streaming services. Everything else – including your homescreen and regular app usage – is displayed in Full HD (1080p).

Sony also gives us the main reason for this – which is very logical, if we may add. The reason for switching is that while Sony does have that 3,430mAh battery on the Xperia Z5, and the Qualcomm chipset pitches in with its quick charging feature, using 4K on everything will still have a big impact on battery life, so the decision to downscale to 1080p on normal usage was needed. Secondly, there are very few apps, if any, that are designed to run on 4K resolution.

That said, with these features in the phone, Sony says that it is confident that the Xperia Z5 Premium will give you prime performance when you need it, even in 4K. Sony has even put in a STAMINA Mode, where it kills off unneeded processes and connectivity when not being used. It’s going to be a few weeks still before the Xperia Z5 Premium rolls out in November, but it looks to be a monster phone – something that Sony desperately needs for its business.
