Sony Xperia Z5 Premium with 4K Prowess to Get into Action Only When Playing Media

September 22, 2015, By Sanjeev Ramachandran

About two weeks ago, Sony made a massive announcement that put their seemingly sinking smartphone ship back under the limelight.

With many in the smartphone community still to experience QHD viewing, Sony revealed the first ever UHD-powered smartphone, Xperia Z5 Premium.

But as it seems, the new display beast is turning out to be good news, and is not essentially 4K all the time. Rather, the 4K viewing ushers up only when you scroll through images and videos.


In a reply to a query by guys at PhoneArena, Sony explained that the smartphone will indeed pack 3840×2160 pixels, but will be put into action only when viewing photos or videos in the device. And in all other cases, the display will hammer its resolution to either 1080p, or even less.

It means that your normal webpage surfing or gaming experiences won’t have the sharpness of even a QHD display. The reason pointed out by Sony is that it ensures a better battery and overall performance for Xperia Z5 Premium.

That explains how they have managed to claim a battery life of two days for the device, even with having a 3430mAh battery and UHD resolution.

The device will automatically switch to 4K when it matters the most, says Sony. Unfortunately, what matters are only videos and images.


The display was introduced by Sony earlier this month as the world’s first UHD display for smartphones. With a size of 5.5-inches, it’s also the smallest display running on a 4K resolution, raking up a massive pixel count of above 800 ppi.

Xperia Z5 Premium is expected to make its debut during November, with Sony expected to launch the flagship Xperia Z5 a month earlier.
