Your iPhone will charge slower depending on when your geographical area's power grid has the most carbon usage. That could be 1-5am, but not necessarily.
Edit: Some research showed most carbon energy is produced during the day, so the situation is the exact opposite of what you're saying. Iphones with this setting will be charging more slowly during the day.

Reply to comment by MVPizzle in If you noticed your iPhone is charging a little slower it may be due to a new setting Apple added in iOS 16.1 — Clean Energy Charging. With it turned on, iOS will only recharge the iPhone's battery when the electrical grid uses cleaner energy sources like solar or wind. by RonSwazy
