Since we know you're dying to find out what's fresh, let's dive straight into the details. The Z2 features a 5.2-inch full HD (1080p) Triluminos display encased in an one-piece aluminum housing. It's the first device to include Qualcomm's new 2.3 GHz quad-core Snapdragon 801, which is supported by 3GB of RAM, 16GB of internal storage (with microSD support) and a 3,200mAh battery. Sony's using the same 20.7-megapixel Exmor RS camera found in the Z1 (although there's 4K recording support tucked away), opting for a slightly improved 2.2-megapixel shooter on the front. That's all protected from a watery demise by IP58 waterproof certification.
The end result is a handset that has been upgraded in nearly all departments. While the Xperia Z2 slightly taller and thinner than the Z1, you'd be hard pressed to identify it in a lineup alongside its younger sibling.
One area that Sony has improved is the display. In an effort to further optimize its screens, Sony's Mobile teams worked with its TV engineers to outfit the Z2's Triluminos IPS screen with BRAVIA technology. Live Color LED is one example of that, generating brighter and more consistent color using a mix of red and green phosphor as well as blue LEDs. Our short time with the handset allowed us to see the Xperia Z2 and Z1 displays side-by-side and we noticed significant improvements across the board.
Sony's strong optics make for impressive photos, but its desire to futureproof its handsets has led to developments in the video department too. The Z2 includes 4K video recording at 30 frames per second with SteadyShot image stabilisation, but videos will only play back in full HD on its 1080p screen. However, you'll still be able to zoom in and inspect the stunning detail of your recordings on the device.
If specs aren't enough, Sony's also developed made some camera tweaks to get even more mileage out of it. There's Timeshift video, which'll let you shoot and quickly edit slow motion video at 120 frames per second, better background defocus and augmented reality options are now available for video. Unfortunately, Sony's limited Timeshift videos to 720p at 120 frames per second, putting a dampener on those plans to record a slo-mo of yourself on a slip-and-slide in high(er)-definition.
A strong entertainment focus helps set Sony apart from many of its rivals, and it's looking to push that angle a little more with the Xperia Z2. If the device ticks all of the right boxes and you find yourself heading out on launch day to grab Sony's latest flagship, it'll bundle a pair of MDR NC31EM headphones in the box as a little thank you. They'll do a pretty great job at isolating ambient noise on their own but with a little help from the Z2's built-in digital noise cancelling algorithms, you'll be oblivious to most of the great outdoors.
Beyond the headphones, there's a raft of accessories available for the Xperia Z2. After it unveiled the SmartBand SWR10 (Core) at CES last month, Sony is announcing today that the wearable will go on sale in March in more than 60 countries. It'll be supported a "Lifelog" app, which'll track your movements and include when you've updated your social networking accounts, snapped photos and listened to music -- basically giving you a thorough overview of your day. If you're after professional hardware, Sony's STM10 plugs into the Xperia Z2's headphone jack to capture high quality audio with its two 120-degree microphones.
Sony tells us that for the Xperia Z2 "the difference is in the experience," but given the spec bumps across the board, it's certainly trying to appeal to consumers who want industry-leading hardware and software. The phone is light but sturdy, fast and responsive, and continues to utilize all of the best features from other Z-series smartphones. There's plenty to like about Sony's new flagship, we just hope that stays true when it our hands on it for a full review. It's set to launch globally from March, so we won't have long to wait.
