Many of you will have heard that the Sony Xperia Z5 Premium was announced at IFA 2015 with the world’s first 4K display in a smartphone. Overkill perhaps, but Sony claimed that their device would still be able to last 2 days on its sizeable, but not gargantuan, 3,430mAh battery – naturally, we thought something was amiss, but this perceived mismatch has a very logical explanation. That reason is that the display on the Sony Xperia Z5 Premium isn’t actually operating as a 4K display all the time – rather, it’s 1080p during normal operating and only 4K when it needs to be.
That’s rather genius, for quite a few reasons – most of you will know that when you increase a device’s resolution, you make your device’s processor work harder to do the same things, just with more pixels. This is why devices with the first Quad HD displays, like the LG G3, performed so badly on benchmarks back then compared to devices with 1080p resolution. In this way, the Z5 Premium will continue to perform optimally during everyday tasks, and when you are watching media or playing games, scales up to 4K for the short period that you’re doing it. Not bad, Sony; not bad at all.
