The press release, announcing better duration time for the iPhone battery created a lot of skepticism in the media. But Apple posted more details on their website to avoid anymore speculation.

Here are the highlights of what they said:

Talk Time: Testing was done connected to a 1900MHz network.

Standby: Nothing specific, the just let the iPhone sit on a table for ten days.

Internet over WiFi: Internet over WiFi testing conducted using a closed network and dedicated web and mail server, simulating browsing to 20 popular URLs and checking mail once an hour.

Internet over EDGE: Internet over EDGE testing conducted over a 1900 MHz EDGE, using a dedicated web and mail server, simulating browsing to 20 popular URLs and checking mail once an hour. (Once an hour? This is way not enough for me!)

Video Playback: Video content was a repeated 2 hour 23 minute movie purchased from the iTunes Store.

Audio Playback: The playlist consisted of 358 unique audio tracks, a combination of content imported from CDs using iTunes (128-Kbps AAC encoding) and content purchased from the iTunes Store (128-Kbps AAC encoding).

Testing were conducted by Apple in May and June 2007 using preproduction iPhones and software. All settings were default except: Call Forwarding was turned on; the WiFi feature Ask to Join Networks and Auto-Brightness were turned off.
