What does the low battery figure in Insights show?
Low battery shows the share of devices reporting a battery level below a set point. It helps you spot tablets that will go silent soon, since a flat device cannot sync or report location. Skie states no figures for battery impact of its own; the figure only reports what devices say.
A flat battery is the most common reason for a device to go quiet. Insights gives you the low battery share so you can see it coming rather than finding out when the device goes silent.
Each device reports its battery level as part of its regular check-in, and the figure counts those below the set point. Because it rides on the check-in, it is only as fresh as the last-seen time. A device that is already silent can't tell you its battery is low, which is why a rise in low battery often shows up a little before a rise in silence.
The practical use is operational. In a school, a low battery share at midday points to charging trouble in a trolley or a classroom. In a hostel, it points to students not charging overnight. For a delivery fleet or field team, it points to chargers in vehicles that are not working. In each case the right response is a person with a charger, not a change in rules.
Skie does not publish figures for how much battery its own service uses, and results depend on device model and use. During a pilot, compare a few devices with and without heavy use, and see how the figures behave on your hardware. See run a pilot.
Practical tip: look at low battery alongside the online and silent share. If both rise together on the same group, charging is the first thing to check.
