My query still hasn't been resolved. The first response was very unsatisfactory. I replied within hours and still haven't had a response 4/5 days later!Please don't preach to me about how to reduce battery consumption like I'm some kind of fool. I know very well how to save battery, it's nothing to do with that, purely that the battery is messed up. I need a replacement battery. I paid £519.99 for my watch, I expect more from Garmin than this.
