My wife use XPERIA Z1 Compact for one year and i own XPERIA Z3 Compact for half a year. When i buy XPERIA Z3 Compact, i make little comparision of this phone and Z3C was better thanks to CPU, size, battery, display, screen recording or Ultra Stamina. But after update both phones to Android 5.0.2 Lollipop i thing that Z1 Compact is near Z3 Compact and everybody, who buy Z1C, make very good thing. Do you think about upgrade to Z3C from Z1C? For me is important that both phones have enough performance and still work without problems.

PS: i am posting here in Z1C section and Z3C section too, because it belong to both section...
