Much like the signal issues with the iPhone 4 release last June, the launch of Apple's much-improved dual-core model has been dogged with problems - the battery being the main culprit this time around.
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.
One of the many complaints leveled at the iPhone design is the closed case, with no user-serviceable batteries. This has spawned multiple cases with inbuilt power supplies for extending the iPhone's sometimes anaemic battery life. Granted the iPhone 4 is a great improvement over past models in the power department, but every little helps. But what if you don't want a case with the added bulk of a battery?
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.
Battery Percentage meter option is officially available on iPhone 3GS only running firmware 3.0 and above; however, there is a small tweak available in Cydia which can enable this functionality natively on the original iPhone and iPhone 3G running firmware 3.0 and above. You will need to have a jailbroken iPhone for this to work.
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.
