Network Control Fast Dormancy to Boost Smartphone Battery Life (Implemented in iOS 4.2.1)
A new technology has emerged called NCFD or Network Control Fast Dormancy created by Nokia Siemens Networks. The technology makes the cellular network and the smartphone work together to create the best conditions for smartphones to connect quickly, yet have a long battery life and minimize network congestion.
Modern smartphones connect almost constantly to the cellular network whether user uses it or not. Actually, the device switches between active and idle states in very regular intervals to pull emails or notifications. All this disconnecting and reconnecting takes time and can cause a frustratingly slow network response. On the other hand, leaving the smartphone in an active mode all the time drains the battery very quickly.
Nokia Siemens Networks has introduced an intermediate state that allows smartphone can wake up much more quickly and needs to send far fewer signals to and from the network to start a data connection. You get a fast network response and a longer battery life.
Unlike other farfetched technology, NCFD has been utilized by Apple in its latest iOS 4.2 and Nokia also implemented the technology in its smartphones earlier this year.
Initial tests have shown NCFD can prolong substantially battery life and reduce network congestion: 11hr from 6hr and up to 50% less signaling, figures claimed by Nokia Siemens Networks.
NSN is a joint venture of Nokia of Finland and Siemens of Germany, its customer base includes 1,400 customers in 150 countries. The company recently acquired the wireless-network equipment division of Motorola for $1.2 billion
