Microsoft Touch Mouse Question

Anyone knows if the touch mouse goes to standby automatically as like every modern $20+ wireless mouse? I just had to replace my first battery set after 3 weeks, the Logitech mouse it replaces (3 yr old) had a battery life of around 8 months and I'm one heavy computer user (10+ a day). I've noticed that the blue-track led does dims and blinks after a while of been idle, but it never seems to go off completely.

This mouse fits very nice in my hands and has great tracking but its got to be one of the worst Microsoft products ever. Gesture sensitivity varies a lot from app to app and you are really better of just using the default drivers that comes with Windows 8, scrolling is a royal pain with most apps.
