Q: A couple of my friends are saying that a charging mode on the Apple iPhone’s latest iOS release is “woke” and “virtue charging”. What the heck are they complaining about?
A: Let’s start with some basic concepts.
First off, not every source of energy is equal in terms of its environmental cost. Some have more impact due to greater or more noxious emissions, while others require scarcer resources. Further, as every EV car owner knows, the cost of power is partially based on demand; electric vehicles typically defer charging overnight until electric is at its lowest cost.
It’s reasonable to observe that environmental cost isn’t the only factor to be considered when it comes to charging a car or a phone. If you’re running out of power at lunchtime, the last thing you want is for your device to refuse to charge until 3:30 a.m. when power’s least expensive.Which brings us to Apple Corporation. For many years, the company has been experimenting with various charge features to both minimize the cost of drawing power from the grid and maximize battery life.
Apple also has an unfortunate track record of implementing changes without notifying customers. A few years ago the hullabaloo was about iPhones slowing down charges to eke more life out of a older batteries.
Clean Energy Charging
Which brings us to the latest addition to the iPhone, as enabled for everyone who updates their iPhone to iOS 16.1. Located in Settings > Battery > Battery Health & Charging, “Clean Energy Charging” is described by Apple as:
“In your region, iPhone will try to reduce your carbon footprint by selectively charging when lower carbon emission electricity is available.”
Does that mean that your phone will refuse to charge when that “lower carbon emission electricity” is not available? No, it doesn’t. As Apple further explains; “iPhone learns from your daily charging routine so it can reach full charge before you need to use it.”
In other words, even…
