Following a video preview of Flash running on a Nexus One, Adobe rebuffed claims that the software slashes battery life. Per Electronista, several bloggers observed that the battery charge indicator dropped from the 50% level down to 25% during the eight minute video. The preview was edited, however, making it unclear how long the team actually used the phone during filming.

In order to refute the battery claims, Adobe has created another video showing a 17-minute YouTube movie which does not appear to significantly drain the battery. The battery usage chart suggests the browser only accounted for 6% of the drain while the movie was playing.

Adobe claims Flash Player 10.1 enabled video playback for “well over” three hours on a fully-charged battery.

Whether this will make its way into current or future versions of the iPhone has yet to be seen.
