Before the V270 became readily available, I was using a Microsoft BT mouse. It initially chewed through batteries at a great rate until I got the idea of using the plastic from the shipping blister pack as a slip cover, to make sure that a button couldn't be accidently depressed while it was in transit in my laptop bag. This improved battery life significantly.
I subsequently used one of the plastic offcuts from the butchered blister pack to make a small isolator which I could slide in between the batteries and the contact terminals in the mouse (which does turn it definitively off). This produced a further improvement in battery life.
Since getting the V270, I have been using the MS BT mouse in a normal desktop role and have noticed in that role it gets good battery life, even when left permanentky turned on.
My conclusion from this experience are:
1. If a BT mouse is just sitting out on a desktop, it seems to be much quite modest in terms of battery consumption, even if reasonably heavily used.
2. The point with being able to turning a BT mouse off, is related to having it in your carry bag in such as way that it ends up with a button depressed, because something in the bag is permanently presssing on it. Under these circumstances a BT mouse appears to be able to chew through batteries reasonably quickly. So, if you can definitively turn it off, you avoid that problem.
The fact that there are now at least two manufacturers who provide on/off switches on their recent BT mice models would seem to suggest that I wasn't the only BT mouse user who experienced excessive battery usage under mobile field use conditions with earlier BT mice that were simple adaptions of existing non-BT wireless mice!
