I can't really say. Until it completely broke my connectivity I was using the nightly builds and there were sometimes other problems with the battery life (like wireless not really sleeping) so it's not easy to say if the drains were caused by loqui or other stuff.

On the newest 1.2 image I have no data connectivity and can only use it with wifi. As that is normally in places where I have a stationary desktop with a client I am not really using it at the moment.
