I just got a new iPhone 2g because the power button on my old one broke and the genius at the Apple Store gave me a new phone under AppleCare. However, the battery life just seems horrendous. I can rarely make it through a single day without having to recharge. Are there any benchmarks that I can test it against. For example, I should be able to run Pandora over EDGE for X hours or something? Is there any sort of utility that I could use to measure the battery's remaining capacity? I would hope that it's in the 90-100% range because I just got the phone a couple weeks ago, but who knows. My phone is jailbroken, so I can probably install an app, if it exists. Thanks!
