The OS: First off, let’s just say that Microsoft managed to do a pretty good job with the Windows Phone 8. It works quite smooth and is a far better interface than the previous Windows Phone 7. But then, Android 4.1 is also a huge improvement over the Android 4.0. Android is anyway the world’s most popular smartphone OS in the world, so Nokia sure has its work cut out for it with the Lumia 920. The display: The Lumia 920 comes with a stunning 4.5-inch full HD display with a 768X1920 pixels. The Xperia Z is a little bigger, with a 5-inch display with a resolution of 1080X1920pixels. No prizes in guessing which one we’d love to look into here. But, if you’re apprehensive about the massive 5-inch screen and how easy it would be to carry around, then we suggest you opt for the sleek Lumia 920 instead. Hardware: The Lumia 920 is powered by a 1.5 GHz dual-core Snapdragon processor and 1 GB of RAM. It comes with 32 GB of internal storage, but there’s no microSD card slot should you need more space on this phone. The Xperia Z is literally a powerhouse, with a quad-core 1.5 GHz Snapdragon processor and 2 GB of RAM. Although it has just 16 GB of internal storage, Sony has included a microSD card slot for those who want more storage space. Camera: While the Lumia 920 comes with an 8 MP rear camera with Nokia’s PureView technology, the Xperia Z has a more powerful 13 MP rear camera. Even the front-facing camera on the Xperia Z, a 2.2MP one, is better than the Lumia 920’s 1.3MP camera. Battery: Nokia’s put in a 2000 mAh battery that offers up to 10 hours of talktime on 3G networks, while Sony’s Xperia Z comes with a 2330 mAh battery giving it 14 hours of talktime on 3G networks. Another huge plus for the Xperia Z is that it is dust and water resistant, making it a far more sturdy device than any other smartphone presently available in the market, the Lumia 920 included.
