Apple Inc. just had a success, making their shares rise in value. They just announced that the highly anticipated iPhone will have a longer lasting battery life than expected. According to the company the cell phone would have up to eight hours of mobile phone talk time or six hours of Internet navigation. Previous statements said that five hours of talk time were expected and the current extra three hours are a great improvement.

Another recent improvement shows upgrades in optical-quality glass from plastic. This makes it more resistance to scratches. As it was stated before, the iPhone will be released on June 29 and it will be available for sale in AT&T Inc. stores and Apple Inc. stores.

The recent announcement of Apple Inc. comes as cell phone manufacturers from around the world are struggling to increase battery life. Communication with radio broadcast tends to drain power and this is becoming a reality in all new sites. Handling Web navigation, music and video playback and talking also drains battery life faster than usual. The closest battery life to the iPhone is Samsung’s Upstage with 6.3 hours while the Blackjack from the same manufacturer only has 5.5 hours of talk time.
