Launched in May 2012, the Nokia Lumia 900 was one of the first generation high-end devices from Nokia to feature the Microsoft’s Windows Phone operating system.
Unlike previous generation Windows OS for mobile phones, Microsoft has completely redesigned the user interface. The Lumia 900 also marked a shift from the Symbian phones that were fast losing out to android and iOS devices. One of the recent versions of the Windows phones from Nokia is the Lumia 1020.
Design
Nokia has always been known for making stylish phones that feature robust build quality and this tradition does not change in either Lumia 900 or Lumia 1020. In terms of style, there is little to separate the two phones since they adopt a similar philosophy. However, the Lumia 900 is very much similar to the N series of Symbian phones.
Display
The Lumia 900 features a 4.3 inch display that packs a resolution of just 480 x 800 pixels. Being an AMOLED display, this was capable of excellent contrast ratios that made the phone screen clear even under sunlight use. The Lumia 1020 continues with the same technology, but it comes with a 4.5 inch display. It also packs in a much better resolution of 768 x 1280 pixels. This makes web browsing and watching movies a great experience on this device.
Even though previous generation phones from Nokia always came with external memory card support, the Lumia 900 and the 1020 do not offer this feature. Instead, they just come with an internal memory of 16 GB in the case of the Lumia 900 and 32 GB in the case of the Lumia 1020.
Operating System and RAM
One of the main aspects of the Windows Phone operating system is its ability to provide a uniform user experience irrespective of the class of the phone. This is true especially in case of the Lumia 900 and 1020. The Lumia 900 offers only 512 MB of RAM. As a result, it misses out on the ability to run the latest Windows Phone 8 operating system. It comes with the Windows Phone 7.5 or Mango OS. Due to its 2 GB of RAM, the Lumia 1020 is capable of supporting the latest WP8 Black edition, although it shipped initially with the Windows Phone 8.
Processor ratings are also vastly different despite the two phones being separated by a time period of just 12 months. The Lumia 1020 comes with a dual core 1.5 GHz processor from Snapdragon and it is assisted by the Adreno 225 GPU. This combined with a very efficient OS like the Windows Phone 8 makes the phone deliver great performance. The Lumia 900 comes with a 1.4 GHz Scorpion processor from the Snapdragon range. It is assisted by an Adreno 205 GPU, which is slightly inferior to the GPU on the Lumia 1020.
Battery ratings are almost similar with the Lumia 1020 featuring a 2000 mAh battery compared to the 1830 mAh battery on the Lumia 900, which retails at just $200 compared to the $420 price for the Lumia 1020.
