On some devices, we need to apply heuristics to determine whether the device is docked on a wireless charger because the charging circuits do not provide sufficient information to know whether the device is on the charger unless it is actually receiving power. The previous heuristics only considered the battery level to suppress spurious dock signals. The new heuristics also take into account whether the device appears to have moved from its previous position on the dock. Bug: 7744185 Change-Id: I5ba885dac25b37840b6db46b8a0f30968a06776c
