It’s worth it, especially if you are going to have the device for a few years. Battery health will last longer.

iPad Pro 80% Battery Limit worth it?

iOS 18 does in fact allow users to set the limit in 5% increments down to 80 percent.
Not sure what other point you were trying to make … just because there’s a continuum of potential choices doesn’t invalidate the benefit. This is a well known enough logical fallacy that it has a name.
Continuum fallacy
The continuum fallacy (also known as the sorites fallacy or the fallacy of grey) is the fallacy of assuming that the existence of a continuum of possible states between two binary positions means that said positions are not different. It is a form of equivocation: treating as equivalent two...
Definitely. I’ve seen a marked difference in battery aging on the devices that support it. Since I plan to keep this iPad for many more years than my previous models (it’s vastly overpowered for my needs), if I can extend battery life it’ll definitely be worth it. I do charge to 100 before I travel, but for daily use? 80% is fine.
What’s funny is you think I’m fretting over details and I think you are… “make sure it’s set to an 80% limit” looks a bit specific to me. My position would be: just take it as it comes and touch some grass in life.

My point was not that a continuum invalidates the point, it was that obsessing specifically over 80% without knowing what that relates to in the physical electro chemistry of the battery is getting very focused on a number without meaning. Apple can change what 100% means tomorrow, as they did with signal strength, or change the battery construction, or a dozen other things and 80% suddenly means something different.
It really depends on whether you plan to keep the device for a while and whether you are someone who used most of your battery every single day. A lot of us use significantly less than 80% of charge on a normal day so there is no downside to turning on the 80% limit. It has no impact on how we use our phones. The benefit is better battery life when the device gets older. There are still some days when I want more battery and I can turn it up to 100%. that preserves my ability to get 100% even when the device is older.
Same with me. Using a Tapo smart plug to charge my M1 iPP to 80% and it works great. The battery degradation seems less to me watching this with coconut battery. On my MacBook I am using Energiza for the same purpose. Especially when you leave your device on power for a longer time this is very useful…
I am doing it since I am driving a Tesla EV. Doing the same with the car and that improved my knowledge about batteries…
Very good explanation!I seem to be using about 50% charge daily on my iPad Pro M4, so going from 80% to 30% rather than 100% to 50% seems like a no-brainer for my use case. When I think I’ll need more I’ll go to 100% of course, I don’t lose sight of the fact that it’s there to serve me, rather than vice versa.
And soon your 80% will be 70% in time frame then what ya going to do?
Use the whole 100% while you got it available to you.
80%now say 8 hours
80% later say 6 hours when things wear down a bit.

Having on at least 2 occasions been caught off guard and ended up in hospital with no powerbank, that 20% may be needed.
I start the day with 80% and at the end of the day, it's still 80% since the devices are always plugged in at the office. 🤷♀️
I use it on devices that support it because it more than halves the wear and tear on the battery. Charging from 0% to approximately 91% has the same cycle wear on a battery as charging from 91%-100%.
Apple’s battery controls on the Mac are limited and mainly an automated setting that is supposed to limit the battery charge level but many of us find that it never quite gets there.
Al Dente is a third-party utility that lets you set the specific charge level you want and it maintains that. There are other features but I only use the charge limiter.
Do you have a source for this, because I'd be interested in seeing how that test was done.
The source was from a battery health app on my previous Android phone which had a slider showing the charge cycle wear vs percentage charged. It was 0.5 cycles at 91%. The app may have been called battery pro or something similar, I don't remember. So I don't know the science behind it or whether or not their numbers were vetted.
Yeah, I'd like to see a technical reference. An app like that is kind of motivated by a belief system.
Every technical reference I find makes it clear that this is not a simple relationship in any way and it's driven by too many variables to focus on any one. Even capacity doesn't have a simple definition-- one paper suggests that charging to higher voltages reduces the charge capacity, but charging to lower voltages increases the internal resistance which leads to lower power capacity. The battery chemistry and physical design impacts the aging impacts of both time and cycling. There are several short term impacts as internal structures form that mean you can't easily experiment with a new battery to look for trends.
80% of maximum capacity of the battery that is inside your device. Apple can’t change that, that is a fixed value for each battery. Don’t overthink it. Using this setting prolongs battery health.
If you're planning on keeping your iPad till obsolete status, it's definitely would be worth it. I've never had luck getting my iPad batteries replaced even though there is definite real world loss of battery run time AND coconut battery also reporting battery wear to less than 80% capacity which SHOULD result in a battery replacement. Apple's diagnostic software always reports 10% higher capacity than coconut battery on iPads which I find odd as iPhones and MacBooks read about the same on coconut battery vs Apple's diagnostic software. I just took it in again 2 weeks ago as it now randomly shuts off. NOW Apple's diagnostic software reports a bad battery at 65% battery capacity. Now the iPad Air 2 is obsolete and they can't change the battery out anymore. What a crock.
No, you’re just complicating something that’s not that important. There’s a setting on your iPhones and iPads that makes your battery last longer. It works. That’s all there is to it. That’s what the OP asked - does it make a difference? Yes it does.
