Data aggregated from the Windows Phone App Store Download Behavior reveals that high-end Windows Phone devices aren’t selling well. Very few people own such devices and the majority of the Windows Phone users have entry-level devices with 512 MB of RAM.
About 70% of the devices accessing the Windows Phone store are from the budget segment that majorly comprises of the Nokia Lumia 520 and the Lumia 530. The Nokia Lumia 520 alone accounts for 25% of all App downloads from the Windows Phone Store.
Only about 20% of the devices accessing the store are from the high-end Nokia Lumia series.
Microsoft provided the data through a series of blog post in a move directed towards encouraging developers to optimize their Apps to support low memory devices.
Low Memory devices is a term used to describe Windows Phone 8 devices with 512 MB of RAM and Windows 7.5/7.8 devices that running 256 MB of RAM.
Windows 8.1 now runs on 65% of all Windows Phone devices, Windows 8 runs on 30% while Windows Phone 7 takes the remaining part. Developers can therefore, now optimize their Apps for the latest version of the Windows Phone OS.
As mentioned above, the Nokia Lumia 520 and 530 are the two most popular Windows Phone devices in the ecosystem. The Lumia 625, 630 and 635, are the three most popular Windows Phone mid-range devices. The high-memory segment is shared almost equally between the Nokia Lumia 1020 and 920.
The Windows Phone Store is now available in 191 markets with the US and China being the markets with the most downloads.
