When it was conveyed that iphone will have 8 hours of talktime, I myself was in a little bit of doubt, but seems like apple very very well understood the concern and has revealed , how the testing was done and added it on technical specification page of Iphone.
Here are the steps :
- Eight hours of talk was measured on the 1900MHz band with Wi-Fi network scanning off.
- Six hours of Internet browsing was done over Wi-Fi or 1900MHz EDGE, on a closed network with dedicated Web and mail server, simulating “browsing to 20 URLS and checking mail once an hour.” (Hahahahah “Once an Hour”!)
- Video playback life of seven hours was measured by playing back a 2:23-hour-long movie, which iLounge thinks is Pirates of the Caribbean: Curse of the Black Pearl, over and over again.
- Twenty-four hours of audio life was measured by playing 358 tracks over and over again, with content from both CDs and iTunes.
Throughout the test, Wi-Fi auto searching of networks was off, for screen intensive tasks, the auto-dimming was off.
