Sony Xperia XZ1  caters to those longing for a premium Android mini, who were disappointed by the X Compact and its lower standing. The full-sized XZ1 on the other hand will try and serve a niche with much fiercer competition.

key Features

4GB of built-in UFS storage and a microSD card slot.
13MP, 1/3.06" front-facing autofocus camera.
Single and dual-SIM models (market dependent).
Snapdragon 835 chipset: octa-core Kryo 280 CPU (4x2.46GHz +4x1.9GHz); Adreno 540 GPU; 4GB of RAM.
5.2" Triluminos display, 1080p resolution (1,080 x 1,920px), HDR video support.
It builds on the XZ Premium Loop surface design and its Motion Eye camera by adding smoother edges and new smoother modes. The 4K screen has gone missing in action, but that had its fair share of doubters at the 5.5" diagonal of the Premium, so it probably won't have seen much love at all here at 5.2". Plus, Sony made it clear the the XZ1 is the direct successor to the Xperia XZ and will bring the Motion Eye goodness even to the markets that didn't get the XZs.



Miscellaneous

The battery is a 2,700mAh non-removable battery, QuickCharge 3.0 support, Qnovo adaptive charging, Battery Care smart charging,no wireless charging available.

the battery capacity usually is not the problem you might have a high battery capacity coupled with a processor that drains a lot of it. on average, the 835 will use around 25% less power, which will lead to a direct increase to battery life.
