Along with the water-resistant design and camera, this phone also stands out for its overall performance. Quick to power up, it launched heavy apps with ease. Even though the camera app consumed a lot of resources, multitasking and browsing were smooth. On the Quadrant Benchmark test the Xperia Z clocked 8117, much higher than the new HTC Butterfly’s 7674. The battery easily gave us a day with the average use.
