Before, I would take the 770 out, take the cover off and it was instantly on and connected. Now I take the 810 out of the sleve and find it has instantly drained its battery and now unusable when I want it.
Now I am thinking what is the point taking it anywhere? the only way I can guarantee it that it is going to work is if I switch it off before, making it much less instantly on than the 770 was.
