Since, Verizon already begins the testing of 5G networks in select regions in the US, commercial rollout is expected to take place in 2019. Because of the built-in dedicated AI processing chil of Snapdragon 855 chipset, the Sony XZ4 flagship will process data much faster and provide better user experience. HDR images and Potrait images will be processed quickly through Image Signal Processor and Hexagon 690.

The Adreno 640 GPU of SD855 is very much improved over its predecessor both in terms of power consumption and performance. The chipset also comes with Quick Charge 4+ support to enhance charging speed and minimize overheating.

The predecessor of XZ4 flagship is powered by 3,330 mAh battery which is beefy, indeed. The XZ2 Premium sports 3,540 mAh battery, but in battery tests and also in real world use, XZ3 is outperforming XZ2 Premium as the Premium flagship sports QHD+ resolution. As XZ4 come with OLED display and FHD+ resolution, Sony may use battery of 3,900 mAh capacity in the flagship.

Albeit, Sony flagships outperform most other flagships in battery life tests, but lag far behind in charging time. The Xperia XZ3 flagship takes nearly 2 hours and 50 mins to go fill completely drained battery. But rivals like Pixel 2, Galaxy S9+ and iPhone X take less than two hours to fullup the battery from zero level. So the Japanese tech giant really needs to adapt new Qualcomm Quick Charge 4+ technology in its next flagship and supply necessary quick charge.

The Snapdragon 8150 chipset is built on TSMC’s 7mm process and offers huge performance improvement and also battery efficient. As Sony will optimize the chipset further to boost performance, Xperia XZ4 benchmark scores might be higher than the above scores.
