Nokia CEO Stephen Elop has reportedly said that multi-core processors are a waste of battery, during an interview with Chinese newspaper Yangcheng Evening News. The Nokia head was quoted as saying that “The so-called dual-core, quad-core mobile phones can only waste batteries, but not be useful for consumers all the time”. Microsoft’s current line-up of Windows phones do not support multi-core processors, and that include’s Nokia’s Lumia line of smartphones. Nokia has launched the “Smoked by Windows Phone” initiative in China, where users are rewarded with 1000 yuan if they’re able to beat the newly released Lumia 900 in tasks that the users choose themselves. Elop says that the Lumia 900 has never been defeated in the challenge, even though its opponents sport dual- and quad-core processors.
