Right off the bat, the new Sony Xperia Z3+ looks very much like the Sony Xperia Z3, down to the 5.2-inch, 1080 x 1920 resolution screen. Inside, though, Sony has opted to go ahead and power the device with the 64-bit Snapdragon 810 SoC which features an octa-core CPU and the Adreno 430 GPU. 3GB of RAM is inside. The rear camera is the same 20.7MP snapper employed on the Xperia Z3 (still no OIS) but the front camera has been bumped from 2MP to 5MP in order to take better selfies. Sony has trimmed the sails on the battery, choosing to enlist a 2900mAh juicer rather than the 3100mAh cell that powered the Xperia Z3. But the smaller battery allowed Sony to cut the thickness of the phone to a svelte 6.9mm from 7.3mm.
The water and dust-resistant Xperia Z2 comes only six months after the previous Xperia Z1 flagship was released. Although it’s quick update, the Xperia Z2 features a larger, 5.2-inch IPS display that boasts a new imaging technology, called Live Color LED. Of course, the screen is not the only improvement over its predecessor. Although it’s even thinner and lighter, the Xperia Z2 runs on the brand new 2.3 GHz quad-core Snapdragon 801 chipset, paired with a fantastic 3 GB of RAM. The 20.7MP camera on its back is capable of 4K recording, slow-motion video, and adding real-time effects. Stereo speakers are now available, as well as noise cancellation and many more software and hardware extras. The Xperia Z2 is powered by a 3200mAh battery, which considerably improves talk time. It runs the latest Android version, 4.4 KitKat. All things considered, the Z2 is an improvement in every way.
