Does this mean the phone only charges during the day? It won't charge at night when solar and wind are least effective and fossil fuel power is used nearly exclusively?

If that's true, it would be most inconvenient for me as I only charge my phone at night, while I'm sleeping. Seems simple enough to disable but to change the charging behavior on an update might be a bit of a shock if you expect your phone to charge at night and it didn't. I'd likely replace my charger first, which is wasteful, before checking if my phone was just "being green."

Fortunately this is answered by the linked article. (This is often a great place to check for information relevant to the discussion title.)

> When Clean Energy Charging suspends charging, a notification on the Lock Screen says when your iPhone will be fully charged. If you need to have your iPhone fully charged sooner, touch and hold the notification and then tap Charge Now.

Wind power is generally higher at night.

Can you provide a citation for that?

I can see hundreds of wind turbines from where I live (all the red lights flash in sync on the horizon, it's kinda creepy). There's definitely more wind during the day than at night here.

And/or at least a higher proportion of energy use.

In reality, Apple is making the wrong calc: it should look at what the marginal electric generation carbon output is.
