I have a desk job that I'm pretty much at my desk 90% of the time and was wondering if I have it hooked up to my PC through USB cable and have it fully charged all day, is that okay to do? Meaning I rather siphon off the power from the PC instead of the battery which might conserve it in the long run from not cycling as much. I use to do that with my Iphone 3g and my battery was still good after using it for almost 2 years. I wasn't sure how the power management was handled on the Captivate meaning is it sucking power from the battery and it's constantly recharging or if it sees that it's connected via USB, it powers the phone from the PC or outlet. Please let me know... I don't want to damage my battery if this isn't good for it.
