Hi, I'm considering buying a droid, but once upon a time I swore I would never buy another Motorola phone. The reason? On my older phones, a v600 and a razr, there was no way to turn off the low battery notifications. On the v600, even when the phone was on vibrate, the low battery notification was an audio tone -- on the razr, when the phone was on vibrate OR silent, it would vibrate when the battery was low -- still really annoying. How does the droid notify you of low battery? And how often? Thanks.
