I am running into a persistent issue on my iPhone 15 Plus running iOS 18.0.2.
Whenever the machine encounters Regional carbon forecast algorithm holding battery level, the following diagnostic log appears in Console:

PowerUI: [CleanEnergy] Scheduling charge hold based on regional grid emission forecast

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