Apple’s iPhone 3GS represents a major upgrade for the company’s smart phone lineup offering a number of improved components that boost its speed and multimedia capabilities. Unfortunately some of its software updates might be silently robbing the device of battery life leaving users in a bit of a jam.

PC World delves into what could be causing the power drain issues and what users can do about it. Here’s a look:

A possible explanation of this phenomenon comes from Wired  ’s Brian X. Chen, who says that it’s likely the iPhone 3GS units with the reported battery life problems are defective. But an interesting explanation comes from the Examiner’s Daniel Nations, who says this is a software problem related to the 3.0 software update rather than defective iPhone 3GS units.

Software updates usually resolve issues…well yeah they’re known to bring up their own fair share as well so you can’t be too harsh on the company if that’s the real cause of the power drain.
