The Nokia Lumia 800 is delivered with Windows Phone 7.5 (Mango), and this platform’s exceptional flexibility essentially guarantees the option of upgrading to Windows Phone 8 once it is launched — this is expected to occur in the second half of the year.
The single-core 1.4 GHz Qualcomm Snapdragon is powerful enough a chipset to make everything run smoothly. Windows Phone 7.5 is a well-optimized operating system which will work immaculately with far slower processors, but the Lumia 800 is a versatile top model and its users will consume a lot of multimedia files, play demanding games, download complex web sites… A dual core processor is usually standard for these activities, but we did not come across a task that ran slowly or with glitches on the Lumia 800, despite its single-core central chip.
The thing is that Microsoft has still not built in support for the most demanding software into Windows Phone, so Internet Explorer does not support Flash elements nor Microsoft Silverlight. It is true that neither does the iPhone, but lack of support for their own technology is a huge flaw for Microsoft. This flaw is present for all smartphone manufacturers who use Windows Phone, Nokia included, because of Microsoft itself. The Lumia 800 is an exceptionally fast device, but partially this is because the tasks which frequently slow down a smartphone most cannot be performed on it either.
Windows Phone is a rather strictly defined platform, almost entirely closed down to all manufacturers when it comes to modifying the user interface, and the Lumia 800 is not different than other Mango devices in this regard.
Still, apart from its design, this smartphone differs from non-Nokia devices with Microsoft’s operating system as it comes with free Nokia Maps and Nokia Drive. If these are not enough, it also also has Bing Maps, which makes this a fully functional GPS device which can be used for offline navigation as well, free of charge. Depending on personal tastes and what individual user wants from GPS, these three applications are quite sufficient and provide answers to every wish. Thus, the Lumia 800, just like many other Nokia smartphones of the new generation, is the best smartphone for those who frequently use satellite navigation.
The 8-megapixel rear-facing camera with F/2.2 of aperture creates photographs of above-average quality, especially compared to the previous Windows Phones. Even under poor lighting conditions, the images are solidly sharp and the colors are realistically interpreted, while those taken with good lighting and in sunlight can be compared to the photos taken by iPhone 4S when it comes to the quality. And it records 720p video clips, also offering above-average quality.
The Lumia 800 does not have a secondary front-facing camera. This is a clear limitation, and not one that can be blamed on Microsoft
The Lumia 800’s battery has nearly the same capacity as the one on iPhone 4/4S, but will last nearly twice as long with the same usage intensity. Such optimization of the platform, with such a display and a processor are quite merciful towards the battery. You should expect less energy frugality from the Lumia 900.
