I'm sure I'll have a lot of questions about this watch as it has a LOT more features than the 910xt, but here is the first one;

How do I set the watch to maximize battery life and ONLY function as a watch? I want to turn off GPS and Bluetooth and Ant+.

The manual states that when the watch is NOT in an activity, it goes into clock mode, but my battery is still going quickly, so something must be running in the background.

Thanks.
