I am running into a persistent issue on my iPhone 15 Pro running iOS 18.1.
Whenever the machine encounters Significant Locations privacy daemon background state sleep on primary iPhone, the following diagnostic log appears in Console:

geod: [com.apple.geod:geofence] Background geo-fence evaluation skipped due to power state restriction

I verified that hardware connections are intact and tested across different power sources. What is the verified diagnostic procedure to permanently eliminate this symptom?
