If you're not aware of the iPhone battery issues that have been doing the rounds online for the last few weeks, then it's fair to say that you've either been on a manned mission to Mars, or living under a rather large and particularly solid rock.
With the various reports of Apple's latest smartphone sapping battery life faster than a vacuum, the company's engineers are said to be scrambling for a fix.
The recently released PwnageTool / Redsn0w jailbreak tools for iOS 4.2.1 requires you to transfer iPad’s 3.2.2 baseband to your iPhone 3GS & 3G in order to unlock it using Ultrasn0w 1.2. This has resulted in poor battery performance as has been experienced by many users. Some users have also complained about their device becoming very hot when in use.
There is now a new jailbreak application available on Cydia which helps in extending battery life on iPhone 4, 3GS and 3G. Available by the name of Auto3G on BigBoss repository, this app basically turns off the 3G radio and switches to 2G (EDGE) when you lock your phone, and turns it back on as soon as you slide-to-unlock your phone again.
There is no doubt about the fact that iPhone is one of the most popular cell phone out there. The argument for a longer battery life on the iPhone is relative in terms of its user requirement. If used as a cell phone, for the primary purpose that it has been designed for, the battery life would be fine and will last probably all day. However, if someone likes to use it as portable computer which I assume most iPhone users are doing, for checking email, web browsing, playing games etc, then the battery is comparable to that of any standard notebook at best.
