    Diagnostic Hardware Specs: iPhone 15 Plus | OS Version: iOS 18.1 | Archive Source: Apple Support Community #256333422

    I am running into a persistent issue on my iPhone 15 Plus running iOS 18.1.
    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?
