    Enabling Siri doesn't use more battery, but using Siri uses more battery. Using an app requires the battery to drain a little, this goes for every app, not just Siri.

    It actually does.. I noticed I get around a hour more battery life without siri.

    This is probably due to Siri audio processing daemon running in the background - it consumes some CPU cycles.

    I have Siri turned on on my 4S, but I rarely use it. So far I have really good battery life.

    That daemon isn't active until Siri is used. Then when Siri is no longer in use, it kills itself.

    No idea why I got nearly a hour of standby without Siri.

    You must have killed the roving bug by turning off Siri.
