Why does my Pawfit turn itself off without sending me a low battery alert/notification?

Question

My Pawfit turns itself off without sending me a low battery alert notification.

Answer

If the phone coverage is poor, it may not be able to notify you with the low battery alert. If the poor phone signal lasts longer than the remaining battery life, it may result in turning itself off without you receiving a notification. 

This can happen if the remaining battery of your Pawfit is limited (i.e. 1 bar left) and it is actively tracking in a poor phone coverage area. The current it draws is high and this can result in the battery draining quickly. This can also happen during cold weather/winter periods, when the performance of the lithium battery in the Pawfit Tracker degrades. If you find that this is the case, please charge your Pawfit tracker when the battery drops down to 1 bar.
