    Hi,

    I just tried juicedefender today and after a while, I checked the battery usage and it shows that the cell standby is on all the time. I know its because to receive calls and txts. But does data use the same radio on a CDMA phone? If so, does juicedefender still save battery?

    Thanks!

    There's only one radio transceiver in the phone.

    Data and voice on CDMA use different signal coding.

    CDMA EV-DO requires more power from the phone, so it might as well some power on that.
