How the updated iPhone battery life claims were measured
MyiTablet has questioned how Apple came up with its improved battery life claim, and has published Apple's methodology. It's all fairly standard stuff - you'd expect their tests to be controlled in such as way as to ensure a favourable outcome.
While they've published the results in full, it really boils down to the use of preproduction iPhones and software, with a connection to a 1900MHz network, with default settings, except for call forwarding being turned on, Wi-Fi feature "Ask to Join Networks" turned off, and Auto-Brightness feature turned off.
Web browsing simulation was over Wi-Fi, on a closed network and using a dedicated web and mail server, simulating browsing to 20 popular web sites, and checking mail once an hour.
Video playback was tested on a 2h23m film from the iTunes Store, while audio testing was done on 358 unique audio tracks from a variety of sources.
Quite how much of a difference those kind of details are going to make is questionable. Far more detrimental to the life of the battery are intensive use of the features all at once, plus moving in and out of EDGE and Wi-Fi areas.
