Sony Xperia XZ4 specs leak: Snapdragon 855, 256GB of storage, and 3,900mAh battery
In regards to other details, the smartphone will reportedly come equipped with 6GB of RAM. This will then be combined with either 64GB or 256GB of internal storage depending on the model purchased. Furthermore, much like the Xperia XZ3 the upcoming Xperia XZ4 will arrive with Android 9 Pie straight out of the box. The flagship is also said to include a respectable 3,900mAh battery.
On the external side of things, Sony looks set to swap out the Xperia XZ3's 18:9 5.8-inch curved edge AMOLED display for a significantly taller 21:9 flat panel that sits at 6.55-inches in size. According to the information, this will be manufactured by LG.
Although Sony hasn’t yet confirmed the existence of the Xperia XZ4, the smartphone will most likely make its debut in late February at MWC, just like previous-generation Sony flagships.
