    Let me start by saying that even I'm skeptical of the claim I'm making because it seems so improbable. However, I can't help but make this association because for the past week my battery life has been terrible and the only thing I've changed is that I put a case on my iPhone 4S. This is the case.

    For example, my battery life is at 23% with 3 hours and 30 minutes of usage and 7 hours of standby. I'm tweeting, messaging, instragramming, and browsing the web every so often. This is all on 3G, but it's basically what I do every day and have no problem getting a good 5.5 hours of usage out of. Then I usually make it home with around 30% and get on wifi. Tomorrow I'm going to take the case off for the day and see if I get different results.

    Anyone ever have a similar experience or can chime in?

    I can't imagine a reason why. If a case effects it then so would it being in your pocket. Do you think the battery goes flat faster with it in your pocket?

    I get what you're saying, but no I don't think that. I mean, I used to have my phone naked and it'd be in my pocket all the time and I didn't experience any sort of problems.

    maybe because it is harder for the cell signal to travel through the case?

    This thought ran across my mind. There doesn't seem to be a loss of bars, but would this matter? Would there be a way to test this?

    Not that I know of. It is not the loss of bars, but rather the extra strength required to penetrate the leather (?)

    Yes, use field test mode a few times both with the case on and off and average the dbm and compare.

    I ran the test five times with and five times without the case with the following results:

    With Case: 1. -64 2. -64 3. -64 4. -64 5. -64 Average = -64

    Without Case: 1. -65 2. -65 3. -53 4. -53 5. -71 Average = -61.4

    That's nothing. Its not the case effecting your signal. You have amazing reception btw...-53 is really good.

    Yeah, AT&T is really good here in Baltimore so it's hard for me to understand when people complain about it. But anyhow, this is still irking me. I really want to know what's going on. Guess I'll just go without a case for the next few days and see if it changes anything.
