> The difference is that Optimized Charging kicks in only when your iPhone is normally idle, typically overnight. The new 80% charging feature (that’s limited to iPhone 15 models) doesn’t try to be as smart, and simply works all day long. That’s not how the Optimized Battery feature works, according to the help text displayed right next to the feature in the Battery Health settings. I question the whole premise of th…

It’s close enough for the purpose of the article.

Related: for MacOS, AlDente allows you to set a battery charge limit. https://apphousekitchen.com/ I've been using it successfully for around a year. It works pretty well sans a couple quirks due to hardware limitations e.g. if you plug in with the screen closed (sleep mode) it will charge fully to 100%.

Wondering if third-party software like this, when not baked into the OS, will have other longterm side effects. Since it can't really put a hard-stop on charging, can it?

I have an iPhone 13 mini as my "work phone "and it's indisputably a fantastic, efficient, small phone. However, I am kind of OCD about keeping it between 40-80% charged, which is a lot of manual toil. Conversely, I also have an Android Galaxy S22+ for my personal phone. The "Battery Protect" feature limits charging to 85%. Life is easy with this device and it causes me a lot less anxiety. Really now, why can't Apple…

My Pixel 6 doesn't seem to have this option.. I never looked into third-party apps for it though.

I highly recommend AccuBattery for Android. I have been using it for a few years now and I saw a noticeable difference on my Pixel 3a XL compared to use on previous smart phones. I now have a Pixel 6 and its nearly 2-years old and the battery lasts well beyond 30-hrs with combined use.

i barely get through the day with a fully charged phone, and i don't get enough runtime if my laptop is not fully charged. so i'd like to know more about the science behind this. how much does the battery life actually improve by doing this. is the trade off worth the inconvenience of a shorter runtime before i need to recharge?

It's for people who only use like 40-50% each day. Going from 50% to 100% puts more strain on the battery than going from 30% to 80%, so limiting the total charge allows the maximum capacity to last longer (in terms of years) than otherwise. And if you do ever need all 100%, just turn off the limit the day before. For me it's a no-brainer: 85% on my current (brand-new) Android phone lasts around 50-55 hours.

I wish they made the batteries slightly larger, then made 100% on the battery meter secretly be 80% of the increased capacity so I could have my cake and eat it.

This makes sense. There are 3 “ways” a battery charges.

1. OS’s battery driver does the charging. This is possible when the computer is on and the driver has control. 2. Firmware driven charging. Typically used in sleep mode 3. Analog Trickle charge - no intelligence, no code is executing. Charge slowly from a dead battery so as to not damage any components.

#1 is the only case where an app. Can control any aspect of charging.

Earlier quoted context omitted.

Going from 85%-25% instead of 100%-25% can increase the capacity by ~25%: https://batteryuniversity.com/img/content/capacity-retention... [0] https://batteryuniversity.com/article/bu-808-how-to-prolong-...

> Going from 85%-25% instead of 100%-25% can increase the capacity by ~25% Capacity or longevity?

Both, as a battery ages from use its capacity diminishes which is why it runs out faster.

That's the point. Apple wants other models' batteries to degrade fast so that the users can upgrade to 15

My X (bought new phone in December when it was released) was at 85+% on the battery. I replace it with a 15 because it was dropping off the OS bandwagon, needed more storage, battery life, lightning port getting fiddly. The OS support was the stake in the heart. If not for that I would have looked into getting the phone serviced with a new battery and port, and cleaned up some storage.

I’m still getting OS updates on my X

Could the decision to support the 80% charging limit for only iPhone 15 be related to changes in battery chemistry? Does the iPhone 15 use a different battery chemistry? I ask because I have noticed my iPhone 15 charges to 80% way faster than my other phones and devices

I just use my phone. The battery can be replaced.
