I am on 1.0.9.58 as well whith no negative effect on battery life. Still 10 days to charge. But what I am missing is the connection as a communication device. It's turned off in bluetooth of my phone. When I make a phonecall I cannot route it to the watch. I have to enable the "phone" option in the phone's BT connection to the watch manually, and THEN I can route the call to the phone. Before this was enabled all the time. But it's a different story...
