At the June 18 press conference in Cupertino, Apple's CEO Steve Jobs made the following announcement: "With 8 hours of talk time and 24 hours of audio playback, iPhone's battery life is longer than any other ‘Smartphone' and even longer than most MP3 players."
Here's another quote from Apple's press release:
iPhone will feature up to 8 hours of talk time, 6 hours of Internet use, 7 hours of video playback, or 24 hours of audio playback. * In addition, iPhone will feature up to 250 hours — more than 10 days — of standby time.
While it's arguable if the increase in battery life will match up to real-world use scenarios, especially since Apple itself claims that the measurements depend on network configurations and many other factors (notice the *), the company gained $4 billion more in market cap since the announcement.
Shares of Apple have surged more than 47% since the announcement of the iPhone in January (MarketWatch). At the same press conference, Apple also announced the upgrading of iPhone's screen from plastic to optical-quality glass. This, along with the power management features of OS X that iPhone will use, may as well provide the increased battery life that Apple claims (Slate.com).
However, results from CNET's lab tests have found 8 to 9 hours of talk time from many new in-market handsets. You can view the battery life charts results here. What's your opinion about the hype that's been surrounding the iPhone? Share your views.
