Sony: This Is How Xperia Z5 Premium Delivers 2-Day Battery Life

At IFA 2015 a few weeks ago, Sony unveiled the Xperia Z5 Premium, the world’s first smartphone to come with a 4K display and 800+ pixel density on board. Sony also said that customers should expect the Xperia Z5 Premium to be able to deliver a battery life of up to 2 days.

Still, some of you might have wondered how that could even be possible. An advanced 4K panel like the one on the Xperia Z5 Premium will put a big toll on battery life, so the claim that the phone could support such a long life cycle seemed pretty questionable. Well, this week, Sony comes to clarify the issue. We’ve been hearing that the Xperia Z5 Premium’s resolution is not always 4K, and now the producing company acknowledges this is indeed the case (as spotted at Phone Arena).

The Xperia Z5 Premium will usually operate at 1080p

The Japanese device maker explains that the Xperia Z5 Premium features a 4K display with resolution of 3840 x 2160 pixels based on SID Standard, which enables all video and image content to be enjoyed in 4K resolution. However, all other content is displayed at 1080p or lower in order to optimize the performance and battery life for the device. The smartphone features a 5.5-inch IPS LCD capacitive touchscreen and includes TRILUMINOS Display for mobile technology. Hardware-wise, the Xperia Z5 Premium is powered by a 64-bit octa-core Snapdragon 810 processor, complemented by an Adreno 430 graphics processing unit and 3GB of RAM.

The flagship handset features 32GB storage inside, which can be further expanded up to 200GB via microSD card slot. On the back lives a 23MP camera sporting a Sony Exmor sensor that can capture 4K video. It also features LED flash and autofocus. In the front there’s a secondary 5.1MP camera for selfies and video calls. It’s also worth mentioning that the Xperia Z5 Premium relies on a 3,430 mAh battery which is larger than what the Xperia Z5 and Xperia Z5 Compact boast inside.

Even with the official explanation out and about, it still remains to be seen whether the Xperia Z5 Premium will be able to deliver a 2-day battery life in real life conditions.
