- Some images look unnaturally vivid
- Not worth upgrading from Z1
The Sony Xperia Z2 was released only several months after the Xperia Z1, but many critics view the latest update to Sony's flagship phone to be markedly better than its predecessor. Design-wise, reviewers can hardly tell the difference between the Z1 and the Z2 except for its weight and thickness. The Z2 is 7 grams lighter than the Z1 weighing in at 163 grams and 0.01 inches thinner at 0.32 inches. As with the Z1, the Xperia Z2's body is constructed from an aluminum frame and tempered glass front and rear panel. Sony also boosted the device's ruggedness by upping its IP certification to IP58, allowing it to be dust resistant and water resistant for up to 30 minutes in 1 meter of water.
Despite its lighter weight and thinner body, the Z2 manages to pack additional features. At 5.2 inches, the Z2 beats out its predecessor by 0.2 inches. With that being said, most critics could barely tell the difference not only in size but quality as well.
The LCD display offers the same HD resolution of 1080 x 1920 and a pixel density of 423ppi. Sony has improved upon the display by adding IPS technology and proprietary color technology called Live Color LED which adds red and green phosphors to widen the color gamut. According to Sony, the technology allows users to boost colors without oversaturating. In real life testing, critics were impressed with the vivid colors, contrast and excellent viewing angles though Expert Reviews states, "some example photos we saw looked unnaturally vivid."
Running the smartphone is a 2.3GHz quad-core processor and 3GB of RAM. PCPro describes the performance as "exceedingly snappy" though they go on to mention that the gaming performance remains the same as the graphics chip has not been updated from the Z1. Generally, however, fast speed was enjoyed and there was no noticeable lag even when utilizing more processor intensive apps. The device also comes equipped with 16GB of internal storage and a 3200mAh battery.
Despite all of these improvements, Sony opted to keep the same 20.7 megapixel camera from the Z1. In addition to many of the same camera apps, it also offers SteadyShot image stabilization. When tested, experts did notice a significant reduction in visible camera shake. Much of Sony's focus went more into video recording as evidenced by the Z2's ability to record 4K video and new Timeshift Video feature that enables users to capture 720p video at 120 frames per second.
As a whole, most critics were impressed with the Z2. Expert Reviews states, "Sony appears to have listened to its critics and genuinely improved its flagship smartphone for the Xperia Z2." KnowYourMobile adds that the new display and faster processor has made "a great handset even greater." Tech Radar, on the other hand, is a bit more reserved about their praise noting, "…it's too much like the Xperia Z1 – albeit a better version."
