My 3GS battery drains significantly while playing games. For example, I just played Geodefense for 30 minutes, and my battery went down 11%. Is that normal? Here is my usage: By the way, I'm not sure why it says it was on standby for 35 minutes, while in actuality I was playing a game for 30 minutes. This is really starting to upset me, because what's the use of this beefed up iPhone, when the battery doesn't have the capacity to last through a game (even though Apple alleges that the battery lasts longer)? Is anyone experiencing this problem, or is my battery potentially the problem? Can the battery meter be the problem?
