Optimized Charging fast charges the watch to 80% and holds it there until shortly before it predicts you're going to use it, then tops it off to 100%. If your charge limit is set at 80%, Optimized Charging is redundant since it's going to stop at 80% anyway.I could have sworn with iOS 17 and the 15 pro, you could enable ‘Optimized Charging’ when setting the charge limit to 80% etc. With iOS 18 and the 16 pro, you can only enable optimized charging if the limit is set the the default 100%.
Maybe someone with a 15 pro still on iOS 17 can chime in and tell me if my memory is accurate or not.Optimized Charging fast charges the watch to 80% and holds it there until shortly before it predicts you're going to use it, then tops it off to 100%.

This never worked for me since iPhone 13!? I turned if off/on and I checked the GPS settings....etc all good but it does for my watch and my Airpods.Optimized Charging fast charges the watch to 80% and holds it there until shortly before it predicts you're going to use it, then tops it off to 100%.

I'm the same. I'm not going to obsess over my battery or make it a contest to see how long I can keep the battery health at 100%. I charge it to 100%, use it all day, and charge it to 100% again the next night using Optimized Charging and a MagSafe charger. My 13 Pro was at 79% battery health after 3 years of hard use, if I had kept it I would've replaced the battery and kept on trucking. I don't have any problem paying Apple for a new battery every 3 years if I decide I'm going to hold on to the phone longer than that (which I've never done yet, going clear back to the iPhone 3G).Maybe someone with a 15 pro still on iOS 17 can chime in and tell me if my memory is accurate or not.
I don’t see it as redundant if one has done nothing but changed the charging limit. Optimized Charging can still operate as intended with a new limit set. With iOS 18, I chose to keep ‘Optimized Charing’ enabled. I am not really worried about the battery as many here often get. If for some reason I have the phone for more than 2 years and in need of a battery, I have no problems paying Apple for the service.
I've used charge limit on my MBA, because it stays plugged in almost 100% of the time—
Theoretically you could probably last a good 10 years doing it this way! LOLWell my data point is pretty interesting.
iPhone 15 Pro Max
247 cycles
100% battery health
I have shortcut automations that keep my phone between 50 to 55 percent via a smart plug. Maybe it drops to 30 percent at most if I’m away from a desk, but I’m mostly next to a charger all day. On the weekends I let the phone charge to 80 percent and since there’s a charger in the car I may bounce back up to that a couple of times during the day.
Just checked CoconutBattery and it says I’m still at 103% of design capacity!
How are you doing this? I don't see that option on my M2 MBA battery settings on Sequoia.

I have an M3 MBA.

My MacBooks are also plugged all the time and just do it by themselves to preserve the battery
