At the end of 2015, Sony Mobile Indonesia brings Xperia Z5 Compact, Xperia Z5 and Xperia Z5 Premium which powered by the notoriously hot Snapdragon 810. The display is the thing that sets these phones apart from Z5 Premium which has the highest 4K resolution.
Unlike Xperia Z5 and Z5 which have compact frosted glass backside, Z5 Premium has clear-shiny glass backside with gold and silver color. The Dual-SIM (support 4G) and microSD slot has protection cap and located on the left side, micro USB port and lanyard slot is on the bottom side, audio jack is on the top side while shutter, volume, and power button are all on the right side. It’s more convenient to use with two hands since it has a square design, large dimension and it weighs 180 gram.
Even so, male users should have no problem using this phone with one hand. We don’t discuss much Z5 Premium UI since it has the same UI and already discussed in Xperia Z5 compact video. Basically, this phone runs similar to Xperia UI which is based on Android 5.1.1 and consumes 1.5GB of RAM. Xperia Z5 Premium is the first smartphone boasting 4K resolution and 806 ppi. But that’s not its native resolution. 4K resolution is only active when watching 4K video. So when users are browsing, playing games or watching the standard video, the display maximum resolution is full HD.
It’s Sony way to reduce battery drain as well as to prevent the phone from overheating. When we try to play 4K video from YouTube, the highest resolution option is Full HD due to YouTube apps recognize Z5 Premium native resolution as Full HD instead of 4K. So we try to shot 4K video using the phone rear camera and expect to see 4K video upscaled from full HD. Unfortunately, we can’t see any difference between full HD and 4K resolution on such a small screen.
Despite its very high resolution, the 5.5-inch display with Triluminos Display technology is without a doubt state of the art. Xperia Z5 Premium is still powered by Snapdragon 810 2GHz octa-core CPU, Adreno 430 GPU, 32GB internal storage and 3GB of RAM, not 4GB as we expected.
AnTuTu Benchmark v6.0 result shows that this phone scores 53150 points. That’s not a high score at all, especially compare to another flagship smartphone with lower price tag. But its real life performance such as running Sniper X: Jason Statham game is incomparable. Gaming and watching video is more fun not only because it has the superb display but also because it has dual-speaker with clear and detail sound.
Heat is still a problem for the smartphone with Snapdragon 810 CPU. Although this phone is equipped with the dual heat pipe cooling system, the heat still jumps above 40° celsius after playing a game for more than 10 minutes. Xperia Z5 Premium G lens is not so different from the previous generation unless it has the different specification.

The rear camera has 23MP with hybrid autofocus which works fast and produces detail photo with perfect color compare to Samsung Galaxy S6 and LG G4. There’s one weakness, though, the camera is struggling to focus on the very close object. Just like all Xperia Z5 series, Z5 Premium is not suitable for creating depth of field photo with blurred background. Taking video shot is another story. The camera quality is high up there with iPhone 6 Plus. You can choose to shot 30 fps 4K video or 60 fps Full HD video. Focus switching is fast and smooth and the intelligent steady shot feature will reduce the shaky effect.
