Tests by Nokia Siemens Networks have shown that iPhone iOs 4.2 supports a technology called "Network Controlled Fast Dormancy," which makes the network and the handset work together to create the best conditions for smartphones to work quickly, yet have a long battery life and minimize network congestion.

"Smartphones connect constantly to network, often driven by apps. But this creates a huge amount of signalling as smartphones switch from an idle mode to an active state so that they can interact with network, for e.g. to get emails or pull in the latest tweets.

When it has gathered the info it needs, some smartphones then switch immediately into the idle state in order to conserve battery power.[...]

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," explains Nokia Siemens.

The new Apple software release supports this way of working on networks that've the technology implemented.

Nokia also implemented the technology in its smartphones earlier this year.
