Just an fyi...using the brighter flash for anymore than a few seconds will completely wig out your battery meter. My meter stated 80% before...having it on for 20 seconds resulted in the red lined battery and low power warning to come on....
yeah, my battery has been going a little wacky as well.
Yeah, I'd be careful with the bright mode, I don't think the LED was designed to run in bright mode for more than a second or two at a time.
I'll probably put stronger wording in the "Help" section of the app warning about bright mode usage when I do the next update (looks like the Behold and Galaxy use a similar flash control mechanism, so was easy to add support for them, next release should work on those).
