A minor OTA update for Motorola DROID users earlier this week could turn out to be more impressive than expected.  Initially believed to address some basic Facebook issues on the Android 2.0 smartphone, some users are now reporting that the new firmware makes a noticeable improvement to battery life.

The DROID’s excellent 3.7-inch LCD display is one of its key strengths, but it’s also a significant guzzler of power.  Heavy use of the smartphone can see it expire well before the day is through. The update is yet to arrive for installation on every DROID out there; anybody finding their phone has a new lease of life come the evening?
