I've been reading and hearing about Locale. Seems like a very powerful application. How much does it affect battery life while using GPS for the location-based profiles?
Locale is listed by my Droid as having used 41% of my battery in the last 18 hours.
I think it may be wise to find an alternative app, or perhaps not use any rules based on GPS. (e.g. instead of "switch my phone to vibrate when I'm at work" make it "switch my phone to vibrate between 8AM and 5PM M-F")
I read about a time-based locale alternative for exactly this reason (battery usage), but I don't recall the name! Anyone know what it is?
