    Diagnostic Hardware Specs: iPhone 16 Pro Max | OS Version: iOS 18.1 | Archive Source: Apple Support Community #256387934

    I am running into a persistent issue on my iPhone 16 Pro Max 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?

    1. Navigate to Settings > Battery > Charging Optimization.
    2. Toggle Clean Energy Charging to OFF.
    3. For an immediate top-off, long press the lock screen notification and select Charge to 100% Now.

    Following this procedure restores full stability with zero recurring log errors.
