Sony Xperia Z1 review

Synthetic benchmarks and performance

The Xperia Z1 is Sony's second device we meet running on the Qualcomm's latest and greatest Snapdragon 800 chipset. It is powered by a quad-core 2.2GHz Krait 400 processor, with Adreno 330 graphics and 2GB of RAM.

The Krait 400 processor clocked at 2.2GHz (2.15GHz according to GeekBench) is among the fastest processors on the market, second to only the LG G2 (2.26GHz) and the Samsung Galaxy Note 3 (2.3GHz).

Our first test is all about single-core performance, where the Xperia Z1 scored similar results to the other Krait 400-powered competitors.

It's time to test the new Adreno 330 graphic processing unit. We ran both GLBenchmark tests in off-screen mode, testing raw GPU power. The Xperia Z1 scored identical results to the Xperia Z Ultra and outpaced all other phones we've tested so far.

The Sony Xperia Z1 is one of the fastest smartphones (phablets included) available on the market right now. There's a noticeable performance lead over the Snapdragon 600 competitors and the snappy chipset makes its presence felt in almost everything you do around the Android OS. Once you get your hands on the Z1, you can't help but appreciate the muscle under the hood.

Google Now at your command

Google Now gives you a short overview of information it believes is relevant to you right now. Going to work in the morning? Google Now knows this and lets you know if there's a big traffic jam on your usual way to the office, and offers you a re-route.

It can interpret a lot of things from your search history as well. If you've been searching for, let's say, your favorite football team, Google Now will prepare a card showing you the next match the team is playing and will provide score updates once the game begins.

Google Now

Google has also integrated Voice Actions. They can handle stuff like sending messages (SMS or email), initiating a voice call, asking for directions, taking a note or opening a site. Google Now can also launch apps, check and manage your calendar and look for nearby places of interest and stuff like movie openings in theaters.

Thanks to the large resolution of the Xperia Z1 display, you can get a lot of information from Google Now with just one glance at the screen.

Google Now on the Xperia Z1 gets activated with an upward swipe from a press-and-hold of the Home button. You can either type or talk to it and the app will give you one of its info cards (if available) and read you its contents aloud (you can disable this from the app settings). If there's no card to help with the answer to your question Google Now will simply initiate a Google web search instead.
