By kamal / April 9, 2013 nokiapoweruser.com First of all, someone asked in the comments about the basis of 21 million WP7.5 and WP8 devices by Q4 2012 , so here it goes. It is based on the WP smartphones volume revealed by IDC from Q4 2011, when Lumia 800 was launched through Q4 2012 , 2.75+3.3+5.4+3.6+6= 21.5 million WP7.5 and WP8 devices considering Q4 2011 to Q4 2012 figures . Now, we thought of predicting Q1 2013 once again now by taking a different approach from our last post where, we tried to calculate volume of individual smartphones . If you remember, in January statistics, WP8 had a market share of 19% which has grown to 43% in April statistics . Now, based on the above chart by volume of WP7 devices by Q4 2012 = 17 million. Now assuming in Q1 2013, Lumia WP7 devices have sold 1.5 to 2 million units (Conservative), WP7 devices volume by Q1 2013 = 18.5 million , which is 57% according to the April chart . Hence from April statistics , overall WP7 and WP8 volume by Q1 2013 = 18.5/0.57= 32.5 million units So, Total WP devices sold in Q1 2013, 32.5-21 = 11.5 million , out of which WP8 devices sold = 32.5 * 0.43 – 3.8 =10 million So, it seems if we use Adduplex data then by whichever approach, we will reach to a really encouraging 10-11 million WP smartphone sales during Q1 2013 . Out of which, Nokia can certainly claim 8 to 8.8 million unit sales . You can read our alternate approach in our previous article, http://nokiapoweruser.com/2013/04/09/nokia-q1-2013-predictions-based-on-adduplex-data-for-april-2013-lumia-920-top-sold-wp-device/ Disclaimer: It all depends on the accuracy of Adduplex data and we will certainly validate it once Nokia reveals Q1 results !!.
