Sadly, so many of the podcasts I used to love have really gone downhill. Or maybe I'm just getting old. I need to get back into audiobooks I guess.
Got a tip for us?

Ok, but what does that 7% get you? 5 more minutes of screen time? 10? Does it last a week longer, a month? There’s no science behind it is the point.
Unfortunately and despite having the setting enabled, my 14 doesn't seem to adhere to it and often charges to 100%. Charging to 80% will absolutely make a difference though, as demonstrated by EVs.
I am a caregiver. Rarely leave the house. No need for speed charge. 15 Pro Max usually set to 80% charge limit but try to charge when drops close to 20% and discontinue at 80. I have absolutely no schedule whatsoever to even try to use optimize charging because usage pattern and sleep schedule is completely arbitrary.
185 cycles. 100% max capacity. Low wattage brick on 3 way wireless charger for watch, AirPods and phone. Usually not charging even two items at a time personally and think it’s on a 5 watt brick.
I have read and do believe from personal experience across iPhone 14, 15 Pro Max… that charging at a slower rate has a positive impact on battery longevity. I have read people use a wireless car charger starting with a consistent high peak battery capacity and after a single use in a vehicle console drop a percent. Not every time they use it, but some say the speed charging, and also through other than Apple devices can have a greater impact sooner on peak battery cap
Anyway, givenI charge at home using a low wattage brick and I’m never in desperate need of an immediate charge and have had several consecutive years of 13, 14, 15 Pro Max with 97 or greater percent peak battery capacity after a calendar year of use when sell them feel like I can confirm slow charging plays a big role and have read similar. Granted this last year it’s mostly been indoor use but in prior years, I was indoors outdoors in cars summer winter…
Also, I’m not a gamer or doing intensive photography/video…..drawing heat on my phone….just kind of light use-though I have the more expensive version
The 80% charge limit, has its written advantages relative to not living at the dead or full charge state excessively as it relates to the chemical make up of the battery.
I think if anyone has the patience to not have to charge their device to nearly full charge in 30 minutes you might see an advantage that way, if it matters to you when charging overnight on a slow charge for people who keep a schedule where they get 4 to 8 hours of sleep regularly

Turned on 80% setting from day one. Only use USB-C, don’t even own anything MagSafe.
Manufactured: November 2033
First Use: January 2024
Cycles: 154
Maximum Capacity: 100%
Battery Health: Normal

rather be safe than sorry when it comes to breaking or losing it.
especially because I stopped using cases a few years ago. just a glass screen protector these days.
Hmmm, my understanding is that this feature is only on 15 and later phones.
Launch day 15 Pro. Optimized battery charging. No other limits selected at any time. 289 cycles, 96% battery health. My wife’s phone is at 92%, and 330 cycles.
This is a great feature and I hope that Apple expands it to MacOS in the future (to be able to use on the MacBook Air and the MacBook Pro)
I look forward to being able to use this feature on my new Series 10 Apple Watch that just got delivered via UPS yesterday (from Best Buy) going to set that up tonight and enable the setting to have the watch only charge to ‘80% limit’
Here is a screenshot of the battery health of my iPhone 15 Pro Max that I bought last October:

It doesn't do anything. It's mainly there to placate high anxiety types. My 15 Pro Max has never had any charge limit and it's at 98% health over 265 cycles. And I charged with 65w adapters or via Magsafe most of the time.
This article was not very well written and the author insists he is correct but was not even aware that Apple has added an 80% hard cap option (which is evidence in itself that it's healthier). It is not really proof of anything. It seems to be consensus among experts that high charge or discharge is more chemically degrading to the battery. Whether it's worth it to worry about that is up to you.
- My 2021 M1 MBA has 97% after 150 cycles. Always using Al Dente for 80% limit, with occasional full charges.
- My launch 15 Pro has 100% after 150 cycles. Always using 80% limit unless traveling and only use about 50% per day anyways so end the day above 20%. Slow charge overnight with low heat 12W.
It doesn't require any effort on my part except turning it off before a trip.
It's a perfect option for someone like me who doesn't usually need the full battery (and when I do I can just change it) and likes to keep devices for a long time. It may just look like a couple of percent, but the battery could start becoming unreliable around 80, so it's actually quite a difference.
But you also don't need to worry about it too much if you do need all that battery - in that case the system does what it can for you.
Just use it as you need.

My wife and I have 14pros. She charges to 100% and leaves it on the charger over night. I manually pull mine off between 90-95% and never leave it on the charger. At the end of two years.....I'm at 92% and she is at 80% battery health. At the end of one year, I was at like 97% and she was 92%.
So not going to 100% and leaving it on the charger matters. I even submitted a feature request 2 years ago for apple to add the max limit to make my life easier. I thought it would only be a software change but my 14pro with IOS18 doesn't have the feature.
When I upgrade, I will use a 90 or 95% limit. I'm not sure 80% is worth it based on what I've read here. My own data says a higher limit is fine. Age is clearly a factor based on how things accelerated in year 2.

Model: iPhone 15 Pro
Maximum capacity: 95%
Cycle count: 327
First use: October 2023
Charging optimisation: 80% (almost all the time)
Switched to “Optimised Battery Charging” less than 10 times on days I need longer mileage.

Doesn’t it have something to do with going below 20% too? I’ve always tried to keep things between the magic 20-80%. It would be interesting to hear from some folks that had the ceiling set who were also focused on the floor.
I had hoped they would extend the ceiling setting to older models. My use cases cause me to leave my devices on and plugged in for long periods and having a ceiling should help prevent damage in those situations.

My 13 Pro Max with 590 cycles (according to Coconut battery) is at 87%. For the first two years, I used to manually unplug the phone at 80%. The phone had exceptional battery life on iOS 15 and 16, so I really didn't need more than 80% in a year. iOS 17 introduced some battery drain during the night, so I stopped doing that. Apple should really add the feature to older iPhones!
If most are like me, they don't need to worry too much about going below 20% because if it gets to 30% much before bedtime I charge mine to be safe (rarely happens).
I always charge it to 100%, I don't care about the battery
My iPhone 15 Pro (non-Max) is at 94% with a 296 cycle count. I don't use the charging limit and charge almost exclusively with MagSafe.
Sounds like limiting your charge is more harmful than helpful considering you ran out of power often.
iPhone 15 pro max. Bought it on launch day.
As of today:
239 cycles
95% capacity
I used 80% almost all year. The times I didn’t were on vacations. For example, Disney World for 5 days.
IMO it was worth doing the 80% limit. I’m planning to keep my phone 3-4 years. It is annoying having 20-something% battery in the evening but I’m usually on the charger around 10%. I rarely charged more than once in a given day. We’ll have to see if I can keep it above 80 before year 4.

Goodness these things are like a bar of soap, no way I’d be without a case lol
