Just some feedback regarding my watch battery issue. I had a phone call from Tag yesterday and they made some changes within the developers settings and have asked me to monitor battery life over next day or so. As you may have read I've been getting 10% drop every hour with the lightest of usage.
The battery level has only dropped 10% in 3 hours this morning which, although early days, is a massive improvement over previous days. So if it continues at this rate, the promised 25 hours is achievable. There is hope yet...
