1. Watch that battery life
One of our biggest complaints about the current crop of smartwatches is battery life — it's not great.

If you're after more detailed battery information, open up the Android Wear app on your phone, navigate to the settings menu, then select your watch.
Open up the 'Watch Battery' section, and you'll be presented with detailed information, including which apps are sipping up the most juice, and when it predicts your battery will run flat.
