The Huan App contains several battery saving optimizations which allow it to detect Huan Tags in the background without draining your battery. 

We have recently introduced a "High Accuracy Mode" setting to the app, which greatly increases detection accuracy and speed, and can be enabled at any time from the Settings panel. You can enable this when hiking or traveling with your pet, and keep it off while spending time at home, where there's no need to constantly detect and update your pets' location.
