On the MWC, SONY’s Xperia XZ2 and XZ2 Compact give us a certain surprise: the full screen, the ultra-thin border design and the back fingerprint unlock. But the Xperia XZ2 and XZ2 Compact are too thick. In fact, there are very few phones with a thickness of more than 10mm, while Xperia XZ2 and XZ2 Compact are 11.1mm thick and 12.1mm thick respectively. Because its border design is extremely thin, the back of both phones has a radian.
If the thickness is for battery capacity, it is still not advantage that XZ2 is equipped with 3180mAh battery while XZ2 Compact 2870mAh battery. After all, samsung has a 3500mAh battery in its 8.5mm Galaxy S9+.
