I usually sell my phone for around $950 each year, unlike the morons that get brainwashed into paying monthly for an iPhone for 24 months or 36 months, or claim they get a free upgrade while they are paying for the highest plan. I just don't want the battery health to drop as much not many people will buy an iPhone for $950 with 90% battery health.You get a new one every year? So what does any of this matter to you? Why cripple your phone's battery for the 12 months you own it?
You will put up with a phone that only has 80% battery capacity in order to prevent the battery of a phone you'll soon be getting rid of from having 80% battery capacity 3 or 4 years down the line. Madness!
Do you also put covers on the interior of your car to keep the seats factory fresh for the next owner?
I don’t know if this has been asked. But what hardware limitations do iPhone models prior to iPhone 15 have that this option isn’t available to the rest of us?

It's purely software. You could manually switch off your charger when the battery reaches 80%.I don’t know if this has been asked. But what hardware limitations do iPhone models prior to iPhone 15 have that this option isn’t available to the rest of us?
I turned it on for me as I drive a lot and my phone is constantly on the charger due to CarPlay.I usually sell my phone for around $950 each year, unlike the morons that get brainwashed into paying monthly for an iPhone for 24 months or 36 months, or claim they get a free upgrade while they are paying for the highest plan.

The Option itselfs says „charge to approximately 80%“ so it can be slightly higher.I can tell you that 80% limit does not work. Mine charged to 86% when I took it out from the magsafe charger.
Keeping it for an extended period: use the 80% setting.Short answer I have is NO. I see no reason to even worry about the battery health of a phone as I consider it a consumable item. I also don't keep my phones over a couple years and sometimes I only go a year when I want to have some feature that the newer phones have.
I don't understand how this will help anything.
From my understanding, these batteries degrade based on charge cycles. So charging up to 80% and using 50% of the battery will give you half a charge cycle. But charging to 100% and using 50% of the battery will also give you half a charge cycle.
What's the difference?
I have noticed my MBP is being held at 80%. For my work the last few months, it's sat around plugged in and I'll grab it to do some quick work on it. The battery has 67 cycles and has 89% design capacity, according to CoconutBattery. macOS's settings says 94% maximum capacity.
Thanks for the update and the reply. Yeah I’m anxious to get mine. I do so much photography on my iPhone and at first I wasn’t going to upgrade because I didn’t feel that the Apple event clarified that the new phones are any better than the 14 pro max that I have. However, after Playing with one in the local AT&T store, quickly realize that it’s quite special. So I went ahead and paid my next up fee to upgrade early on both of my phones. Now all I have to do is wait. I should probably stay away from these forums for a while because seeing everybody getting their new phone causes a little bit of anxiety as I’m waiting for mine. Lol.My launch day iPhone 14 Pro dropped from 100% to 99% capacity about 4 weeks ago. Last week, I sold it to a company (that wanted it to have at least 80% capacity) for ~70% what I paid for it last year. For context, and none of this is directed towards you and your experience, I lived in a hot country for a lot of this year, and I charged the iPhone overnight almost every night on the MagSafe charger of a Belkin BoostCharge Pro charger. I barely ever used a cable, and it was used often with wireless CarPlay. Needless to say, I didn't really go out of my way to look after it, yet it was still on 100% at around the 11-month period. I didn't put it on charge when it was almost full, though, and it rarely ever got very low. My wife charged her launch day iPhone 14 Pro the same way, and it has 98% capacity now.
In general, echoing a lot of what others have said, my point is that it's likely just not worth worrying too much about it. I do care, and I want to look after my devices, but I managed to find a sensible (for me) balance this past year. What I don't see many people mentioning when discussing battery capacity is what they actually do on the phone between unplugging it in the morning and plugging it in at night. They can trickle charge it on the slowest charger all they want, but if they're hammering multiplayer games at full brightness on a 5G connection, pushing the device to its limit, they're likely doing more harm to the battery than leaving it plugged in overnight.
Enjoy your new iPhone when it arrives! I got an iPhone 15 Pro on Friday and I love it.
The graphite anode in li-ion batteries also literally expands and contracts with the charge level by about 10 percent. This physically stresses and decomposes the material. This is why cycling within the midrange is healthier ... you aren't "blowing the balloon" up to 100 percent.Heat, staying at higher voltage (100%) or 0% for long periods have a negative effect on battery health in addition to the normal wear you get from using up charge cycles.
Valid point! Hence the option to go to 100% on busy days. Every day a busy day? Just ignore my advice and go 100% all the way. Tweaking option: get a smart plug and program your phone to charge to 60%, stop and resume charging two hours before you need the phone. it really works.The problem is, by only charging the phone to 80%, you increase the chance to end up below 25% 😂
Today's update:iPhone 15 Pro (Blue 128 GB) first opened and used Friday night (9/22, 7 PM PT)
Plugged into USB while restoring via Quick Setup after first installing the 17.0.2 update. That process is quite smooth and took 2 hours for a 120 GB restore.
Cycle count at that point was 1.
Next day I went around and used it normally to break it in, took pictures. Didn't allow the battery to drop below 50%, plugged it in or used MagSafe battery pack at various points to top it off. Towards the end of the night, I checked the cycle count and it was 2. Then I went into Settings > Battery and changed it to the 80% threshold. I left it on the battery pack before I went to sleep.
Next morning the cycle count was 3. Battery was at 80% as expected. MagSafe battery pack was fully discharged.
While I appreciate the information Apple is providing with this, I'm certain that at some point I'm going to stop worrying about it because I expect to replace the battery in two years assuming that I keep the phone. I also own a decade-old EV with less than 100 miles of range, so I LIVE battery anxiety.
It’s all pretty simple really, but the majority don’t seem to understand what it’s actually for.Hmmm after reading 7 pages of posts I still don't know, if this feature is useful or not, if it makes an impact on the battery life of my 15Pro or not...confusion 🤪
