I’d love to see the science that actually justifies this. How about setting this up on all those eco friendly electric vehicles that people think don’t use “dirty energy”. They just trade gas for the coal at our parent plants.

Bring back nuclear power plants and let’s move on with real sustainable power that’s safer and less polluting!

It really depends on where you live but in CA only 3% of our power usage comes from coal.

Agree. This seems to require a huge amount of backend infrastructure to make a truly negligible change.
My quick calculation shows that charging an iPhone battery requires about 0.015kWh of energy (assuming about 75% efficiency). Assuming you have to charge your phone once a day, this is effectively way less than one percent of most People's daily usage. And yet the number of engineers that had to be fed in order to add this so-called feature probably will not ever recoup the energy deferment (because they're just shifting the charge time)

maybe I'm missing something, but this doesn't do anything about energy production - it just shifts around consumption. So if e.g. 30% of energy is from renewables at a specific time of day and 70% is not, everyone starts charging their phones and overall consumption goes up - that additional consumption has to come from non-renewables. That is assuming that the energy provider prioritizes renewable energy, i.e. renewable fraction is always at the max that can be supplied. So your phone is charged from renewables while now your TV uses non-renewable.
 
Using any electronics is dirty-strip mining, child and slave labor, poisonous byproduct dumping, e-waste, etc. No need to act all high and mighty now.
And by using a computer to post this gibberish, you're helping all those happening, right?

Move into the woods and cut communication to the outside then, bye.

My PC consumes 400W 12hr/day, TV 300W 6hr/day, home LED lightings 300W 8hr/day, electric car 8000W 4hr/day, oven 6000W 0.5hr/day, refrigerator compressor 200W 4hr/day, home server 100W 24/7. Even my WiFi router consumes 20W for 24/7. 20W 1hr/day by iPhone charger is too small to save carbon footprint.

Update: I use 1,000kWh / month. iPhone charger takes 20W x 30 days x 1 hr = 0.6kWh. 0.06% total of my house electric bill.

I care deeply about the future of the planet, but I’m turning this off. Only 15% of the lifetime emissions for an iPhone (from birth to the used market to the recycling robots) comes from actually using the phone. Even all of the energy ever used in an iPhone for its lifetime is 9kg of carbon (similar burning a single gallon of gasoline in your car). Reusing instead of throwing away a single plastic bottle does more for the planet than being at all inconvenienced by this.

Agree. I didn’t know who thought this was a good idea. It seems really rather pointless and to turn it on from default speaks a lot about how they are running the company. Don’t worry though, I’m pretty sure there will be a lot of reports about phones taking hours to charge which will make Apple disable this
