I'm using this since november but it's not useful it some situations. Just two hours ago I was outside home with 30% battery and as soon as I started browsing in 3.5g the battery went to 4% and after about 2 seconds the N9 turned off itself, all that before profilematic could do something. This is not acceptable for a smartphone. I think we should do a petition to request a fix for this AND for other critical bugs. Maybe Change.org?
