Hmm. Actually, it IS helping. After installing it and setting it up, I intentionally rebooted the phone a few times (not including a battery pull when the thing froze up)...and it didn't seem to munch on the battery so much. On the flip side, I wound up having to get JuiceDefender Ultimate, because the regular one had a habit of randomly shutting the phone off outright, regardless of battery level, and it WOULDN'T reactivate without either a battery pull or plugging it up, lol. The Ultimate version's been pretty smooth sailing, though. But it definitely isn't making lunch outta the battery as much as it usually does. (However, I may need to get a fresh battery soon anyway...)
