I think I will disable it, because it is not working at all on my iPhone.

I‘m even using “sleep time”, with a daily alarm set at 6:15AM , so it should be quite easy for the phone to learn my habits (at least my wake up time).
Nevertheless the charging doesn’t stop at 80% and goes right to 100%, keeping the phone fully charged for at least 5/6 hours (I’m using the fast 18W charger).

The funny thing is optimized charging is working fine on my wife’s XR and on my son’s SE.

It's a bit of a gimmick IMO anyway.

It does no harm in just regularly charging to 100% and leaving it plugged in - Especially as you unplug every morning. It doesn't keep trying to put more power into a battery that is already at max charge

Sorry but you are wrong.
In the long run a battery kept at 100% for hours will age faster.
It is not a matter of “putting more power” in it.
It is a chemical issue: better not to leave a battery fully charged (nor to deep discharge it every day, which is even worse).

The idea behind “optimized charging” is very good. The implementation is very poor.

But it's not "hours" if you unplug every morning? 3/4 at most, per night once fully charged? And the fact you're letting it discharge rather than just keeping it plugged in is healthy for it

Can I ask, how long do you plan to keep your current phone for? Any less than two years then I can put a pretty good bet that your battery will be absolutely fine for the duration of your ownership.

The battery is negatively affected the more time it spends at 100%.

If it were a "gimmick" then Apple wouldn't need to introduce Optimized Charging.

Even with a 5W adapter, the iPhone fully charges in 3 hours. The rest of the night, it's sitting at 100%. That's a lot of cumulative hours.

I’m upgrading every year 😝
big Apple fanboy here 😂

but I usually give my iPhone to my son or my wife, so I’d like to preserve the battery as much as I can.
i know it won’t change so much, but even a few months over three years could make a difference.

there is a reason for “optimized charging “...

I agree. It is broken.

How difficult can it be? I even have bedtime setup so the iPhone knows exactly when to be fully charged.

Im using the 18W charger, and my iPhone usually ends the day at 40/50%, so it is fully charged in less than an hour... and sits at 100% for 5/6 hours. I don’t like it.

Set an alarm and unplug the phone then.

Or set an alarm for when to put it on charge halfway through the night.

Stressing about battery life must really hamper your enjoyment of using an iPhone.

Wait optimized charging is supposed to stop charging @ 80%? LOL that has never been the case on my iPhone 11 Pro since I got it on every single OS update that I've done. Nice gimmick Apple.

Depends on workload and network conditions. I'm primarily on iPad and barely use my phone but since reception isn't the best at the office, my battery's usually noticeably degraded after a year due to the radios needing to work extra hard.

Remember to update us in a year on your battery health. I bet there will be no major difference.

I had no idea why my charging was being stupid ... then discovered this magical setting was on by default. Turned it off and now everything charges like normal.

Same for me. It always charges to 100% and then it stays at 100% for atleast 6 hours during the night.

At first I thought the machine learning algo was still in the training phase, but after more than a month this is not the case anymore.

Ha! The very first time I noticed the setting on my phone my first impression was “huh what nonsense” and I turned it off. so in conclusion, I don’t think I ever used it.

Same over here...just doesn’t seem to work. Put it on the charger at around midnight and taking it off around 7a.m. Trying to give that damned thing a daily routine but it just does not seem to like it. Quite sympathetic ?

If it only takes an hour to charge, why not just leave it unplugged until the morning? When I wake up, I plug my iPhone in and by the time I'm done with my shower and breakfast, it's charged.

You beat me to it only I was going to say charge it an hour before bed and unplug it before going to sleep. You’ll only lose a few percent over night so will have more than enough juice for your day.

That’s exactly what I’m doing now. It lose not more than 1% overnight.
But I was hoping “Optimize charging” was a better solution.

I've never read a comment anywhere where someone mentioned that Optimize Charging worked
It is absolutely working on my wife’s XR and on my son’s 11 ... I don’t know why not on mine ??‍♂️

I’m actually doing the opposite: charging it one hour before sleep.
But optimize charging was supposed to solve the problem.

I'm missing something, how do you know if it is charged to 100% while you're sleeping? I have the thing toggled on and am not sure I would know if it was working or not?

Umm never mind, I just found it. Sooo I must report that mine charges straight up and parks at 100% for several hours prior to waking.

Odd.

Mine seems to be going up to 80% like it’s supposed to.

There seems to have been something with the last update that causes my camera controls to become unresponsive, though.
