Meh. I charge my phone twice a day and have never, ever had a phone that lasts a full day & evening of heavy use so the last thing I want to do is willingly cripple my battery.

I don't understand the drain to 50% and charge to 80% guys. Life's too short to baby a battery like that but sadly these phone manufacturers cause anxiety and OCD with their built-in batteries.

Just like the Ultra where you can set to only charge to 80% and not 100% unless you wish.

I only use about 20-30% of my battery everyday and do not need my battery pushed to 100% every day.
Agree. That option would be nice to keep the battery healthy, even if it's buried under some settings. Samsung has the option to stop charging at 85%.

Is anybody’s Ultra self-limiting to 80% yet?

Mine arrived on launch day. I think I’ve only charged it to 100% a single time. I charge once per day, when I shower; I don’t think it’s ever been below 25% (with 40%-ish typical), and it’s generally between 80% and 95% when I put it back on.

But it still wants to charge to 100%.

By any reasonable statistical measure, it should know damn well by now that an 80% limit is perfectly fine.

Are Apple programmers just that paranoid? Or am I missing something? Or … ?

Optimized charging seems a bit pointless on a watch unless Apple’s market research has concluded the Ultra will be even more special use case only (e.g., just while hiking) than other models of the Watch.

I only use about 20-30% of my battery everyday and do not need my battery pushed to 100% every day.
The battery should be fine. The remaining charge level may become a little inaccurate if you never use the watch to auto power-off. Otherwise, simply working the battery should prevent premature aging. Only weeks or more of sitting at a consistently very high or very low charge level can cause damage.

Just build a Shortcut and use e.g. an ikea Smart Outlet for 12€. When it reaches 80%, it switches off and it turns on below 60%. Done.

That would cause so much confusion to the general population.

I don’t get this obsession over micromanaging the battery. The optimized charging feature will manage it for you. Don’t try to outsmart it.
In general I don't think you're wrong.
However I do think it would be nice if Apple included more granular control over Optimized Charging. The biggest problem(s) Optimized Charging has is it just flat out doesn't work well if you keep an inconsistent schedule (which is also what it looks like to the device if you try and micromanage the process FYI.)
When turned on it can often require micromanagement to make sure you do have a full charge when you actually need it and conversely that your devices aren't charging to full when its completely unnecessary.

That said, I also agree that there are way too many people who think that just because they read something on the internet about how lithium ion batteries work, they're now smarter than Apple's engineers.

I believe the feature will be coming later and isn’t fully enabled yet. I’m on the 6.1 Beta and have it, so I imagine it’ll be coming soon.

I really don’t get the point behind micromanaging and willingly using half of the battery capacity.

So let’s say that we charge up to 80% and use it until 20%. You are using 60% of the capacity with a brand new phone.

1. The battery is still aging
2. You are already using only 60% of the battery, that is equivalent to a 5-6 year old phone
3. Since the battery ages anyway, the “60%” that you are using is going to be less actual use time every month/year

I can write much more, but there’s no point. Batteries are consumable parts and cost 100 to replace every 2-3 years if you want peak performance.
And if you are fine with 60% of the original capacity to begin with, why bother? The battery will reach that point after 5-6 years anyway, but at least you enjoyed 100-90-80% for quite a few years.

I think the problem is more about leaving the phone charged at 100% for a prolonged period of time. Many people simply charge their phones overnight, so the theory is that if one knows that one won't be using a lot of the battery through the day, it might be better in prolonging the battery health by having an option to charge only up to 80%.

I believe the use of a smart socket to schedule turning off charging at preset percentage is also a good option. I'm just glad Samsung has built in that function in my S21 if I wanted to do something like that 😁

It's an actual option to stop charging and not Optimise charging? Has anyone pics of this option on their Ultra's?
I think Apple called it Optimized charge limit, which put an actual limit alongside the optimized charge feature. It puts an actual hard stop at 80% while giving you the option to override it when needed. At least that's how I understand it from Apple's website. According to Apple, it might top up to 100% based on your pattern

One workaround is to use a power bank that shuts off when iPhone does not draw charge current any more.
So it shuts off i.e. in the middle of the night because iPhone learnt that you usually use it in the morning. It would "like" to charge from 80 to 100% an hour or two before you get up, but cannot because power bank shut down.
(I have such a bank that needs to re-enable the USB charger output ports with a button press).

Meh, just use your phones, people. I charged my 13PM whenever I needed, using magsafe 99% of the time, used the phone for a whole year and the battery health was at 100% at the end of that year.

Babying your battery to save it from degrading, by using less of the battery, means you're living as if the battery has already degraded. If you're using 80% of the battery, then you're manufacturing a scenario in which your phone behaves like it is at 80% battery health.
