Apple's promotion to number one in the 2011 table of 100 most valuable global brands has not been part of a wider positive trend for smartphone providers, according to the 2011 annual figures.
BlackBerry is valued at $24bn, down 20%, while Nokia was down 28% to $11bn.
Apple’s brand value rose 84% to $153bn.
This is the sixth annual Millward Brown Optimor BrandZ Top 100 Most Valuable Global Brands study.
It identifies and ranks the world’s most valuable 100 brands by their dollar value and is used by businesses to assess: how much brand drives revenues, growth and market capitalisation and builds long-term financial value.
Nokia, which had a dominant position in the mobile market three years ago, has lost share to rivals who have produced more appealing smartphones, such as Apple and HTC.
Nokia's internal problems were aired publicly in February with the leak of a memo written to staff by its new chief executive Stephen Elop, trying to get them to realise the degree of trouble the company found itself in.
Elop wrote: "The first iPhone shipped in 2007, and we still don't have a product that is close to their experience. Android came on the scene just over two years ago, and this week they took our leadership position in smartphone volumes. Unbelievable."
The week after, Elop took Nokia into a strategic software alliance with Microsoft, which partly sidelined its own Symbian operating system.
The company shed 1,700 jobs in the year to November 2010, and last month announced another 7,000, including 700 in the UK, would go.
Likewise, BlackBerry has been affected by the rise of Apple and Google's Android operating system.
Its brand value decline comes despite it posting record profits in the third quarter of 2010. It has been attempting to appeal to a wider customer base than its original business audience, and is preparing the launch of its first tablet.
However, there are signs that not all is well at Research in Motion, the brand owner - it parted company with its chief marketing officer Keith Pardy in March.

Other technology companies, meanwhile, have also reported mixed performances this year.
Facebook was one of eight new entrants in the top 100 and the highest newcomer, coming in at 35, with a valuation of $19bn.
Vodafone was down two places to 12 while US telecoms brand Verizon was up seven places to 13. HP was down six places to number 18.
Nintendo, the maker of the Wii and Nintendo DS, was the second biggest faller in top 100, plummeting 47 places to number 79.
Millward Brown claims its survey is the only brand valuation study in the world that takes into account what people think about the brands they buy alongside rigorous analysis of financial data, market valuations, analyst reports and risk profiles.
