But what you probably do not know is that Sony plans to add a fourth member of the Xperia family Z5, at least according to Chinese cnBeta web (via Android Authority).
This new model will come to Japan with NTT DoCoMo operator, and will be an improved variant of Xperia Z5 Compact, to be called Z5 Compact Premium.
This model will carry the same Snapdragon 810 processor and look similar to Z5 Compact, but replaces the 2GB of RAM 4GB, 720p resolution screen 4.6 "with 1080p resolution, and battery capacity of 2700 mAh by 2,900 mAh.
Curiously enough, this model even has more RAM than the Xperia Premium Z5, and the truth is that it sounds a bit strange.
