Each update requires GPS signal (direct view of the sky), GSM signal (mobile reception) and movement. Without these three necessities the tracker will not update or give accurate location updates. E.g., When the cat is indoor. In this case, the app will just show the last locked GPS location (outside) before the cat went indoors or show a weak GPS signal update from afar. In other cases, if the cat is close to an building or property and just lazing on the deck or driveway this can also trigger inaccurate GPS sway points which can be up to 200 metres or more off its location, this is because when movement is minimal and the tracker is wedged between the neck and the ground signals can be blocked. Basically, GPS trackers work best when outside and on the move but a full guide is given to help you determine its accuracy based on signal strength. 

Geo-fencing may trigger false alarms due to inaccurate GPS sway points as explained above, this is not a fault but a characteristic of bad GPS signal when indoor or when the tracker is wedged between the pet and the ground/fence etc. Users are advised to set a Geo-fence zone not too close to homes to reduce false alarms. 

The accuracy of each update depends on the GPS signal strength and the accuracy of Google map in the area and can vary from 0.5-30m+. Inaccuracies occur most often if the tracker isn't moving much or is wedged between the wall or ground. Poor GPS signal which occur indoors or under shelter can provide inaccuracies of up to 200m+ or even 1000m in certain environments. This is the characteristic of all real time GPS trackers as they work best when "on the move" and why we stress that you must always check the GPS signal strength before determining the accuracy of each update.

Battery life varies between 4 hours to 4 days depending on how active your cat or dog is, reception strength, and update mode. For example, if your cat stays indoor all the time where reception is poor and GPS signal is blocked indoor while on urgent mode, you’ll likely get around 4-5 hours. If your cat is outside where reception is good and is lazing around all day in power saving mode, you’ll get around 3-4 days in one charge. Charging takes around an hour with a proper USB outlet, do not use your laptop or PC USB port.
