Reviews Word on the street

Xperia Z  vs Optimus G Pro 

Fans of the Xperia line and Sony's software will no doubt love the phone, with the possible exception of battery life, but those who aren't loyal to the brand may find the durable metal casing and better display on the HTC One and the myriad features and replaceable battery on the Samsung Galaxy S4 more captivating.
Xperia Z

That sounds pretty good, but keep in mind that if you regularly use your phone for more “advanced” stuff like camera, GPS, video playback or gaming, the battery life will quickly drop to one full day.
