Sony: Here’s the secret behind Xperia Z5 Premium’s 2-day battery life

By  | 

Sony made headlines with the announcement of its Xperia Z5 Premium featuring 4K display establishing itself as the first company to fit 4K display in such small form factor.

What followed was a mixed set of feeling from the proponents and opponents of 4K display in a smartphone and while the debate was raging on, there was one group of people that questioned Sony’s claim that Xperia Z5 Premium was capable of full 2 days of battery life. How can a smartphone having a battery-intensive 4K display manage 2 days of batter life?

Further, those who managed to get their hands on one of the handsets for review purpose quickly started noticing the difference between display when normal content was viewed vs. images and video files. It was becoming apparent that there was something going on. And just as people starting questioning this and the long-lasting battery claims, Sony made it clear why it is making those claims.

Xperia Z5 Premium doesn’t actually show you everything in 4K and that’s the reason Sony can claim that the phone has a 2-day battery life. While you will certainly enjoy images and videos in a whopping 4K clarity (files that are actually of those resolution), the Z5 Premium has a nifty trick under its sleeves when it comes to displaying other content like email, web pages, apps, etc. It will revert to a more battery-conserving 1080p display or even less resolution depending on the content for all content other than media thereby saving you the much required battery juice.

This is the statement from Sony:

Xperia Z5 Premium features a 4K display with a resolution of 3840×2160 pixels based on SID Standard and enables all video and image content to be enjoyed in 4K resolution. All other content is displayed at 1080P or lower resolution in order to optimise the performance and battery stamina for this device, ensuring you can enjoy the 4K resolution when you need it most.

Fancy getting one for yourself? You can pre-order it on Amazon and have it delivered on December 1, 2015.
