It slows down and times its charging to reach the 100% right before you get up in the morning, rather than immediately after you plug it in (which would make it 100% all night long).
So in other words, the limiting only works overnight.
So, again, what is the difference from what you quoted? Is it the implication that it might work at other times of day when the phone is "normally idle"? I don't even know if that implication is true or not, since it depends on exactly how the phone calculates your schedule. But if that's your complaint, it seems pretty small to me, not enough to throw the rest of the article into question.
It doesn’t work if I plug my phone in at 9am in the morning. It will charge my phone to 100% immediately in that case. Even if I leave it connected to power all day. Breaking my battery.
Optimized charging is based on learning and thus unpredictable and hard to influence. It only works if you have rigid habits.
The article says it only works in that situation, not that being in that situation is a guarantee of it working. I think the phrasing is fine. Do you disagree?
Like, if I say my car only starts when it has gas, I'm not promising it always starts as long as it has gas.
It's far from a comprehensive list of things that break the feature, but it gets the point across that the existing feature does a fraction of the job at best.
No, it works any time of the day. It just depends on your charging habits. And it also depends on your location, if you’re away from your primary location, it still charges to 100% when plugged in during your normal charging times.
The article says it only "kicks in" at certain times.
If your argument is that it "works" all the time even when it's not affecting charging, therefore the article is wrong, you are splitting hairs in the worst possible way. And if you're not arguing the article is wrong you might need to reread the comment thread.
Please say what the difference is, then?
