Apple's new M4 iPad Pro and M2 iPad Air models feature a battery health setting that is new to iPads and when enabled prevents the devices from charging beyond 80% at all times, which can extend battery lifespan.

When the 80% hard limit is enabled, the iPad will never charge beyond that percentage, except on rare occasions to "maintain accurate battery state-of-charge estimates," according to Apple. Apple says reducing the time that a battery is fully charged can reduce the wear on the battery and improve its lifespan.
From Apple's support document:
How to Set an 80% iPad Battery Charge Limit
- Open the Settings app on your M4 iPad Pro or M2 iPad Air.
- Tap Battery ➝ Battery Health.
Tap the switch next to 80% Limit to turn on the feature.Note that from the new Battery Health settings menu you can also view the manufacture date of your iPad's battery, as well as the month and year on which it was first used.![]()
On M4 iPad Pro and M2 iPad Air models, you can also find out the cycle count of your device's battery. To learn why this matters, be sure to check out our dedicated how-to article.

The thing is, the same type of non-user-replaceable batteries can be found in so many devices today, and most aren’t failing in a year, let alone 3+ years. There just isn’t the need to make user-replaceable batteries that there once was. Ask me how I know - I’m old enough to have been an adult when the first bag phones, then handheld cell phones came to market. I’ve owned so many including multiple phones where I did have extra batteries I had to carry with me while traveling for work. It was bad enough that most of these batteries lasted just a couple of hours, but to add insult to injury, when you were opening the back case to get the battery out on a regular basis, that back stopped locking in place, eventually failing and then requiring tape to hold it on. And this was within a year of far less use that phones get today.yeah i’m sure like everything else replaceable battery technology would also remain stagnant for decades
selling disposable products is simply more profitable otherwise we would have replaceable batteries in just as thin devices
keep up the yearly cycle i’m sure it will last forever

For the VAST majority of people, the battery isn’t the sole or main reason they upgrade to a new device, it’s often the fact that the device is so old that it doesn’t do what new devices can. Sure, for some, the battery doesn’t last as long, after 3-4 years of daily use, but it still doesn’t make as much sense to get a new battery installed, compared to upgrading to a new device, so that you can get a device that is more powerful, offers better screen and cameras, and also lasts the whole day of use.
I think he was trying to say is Lithium batteries have memory and over charging it mess up the memory of the battery. So the battery start charging it and stop at different charge cycle.This is the sort of nonsense that wouldn’t fly with Steve Jobs still around.
It’s amazing to me that people limit their devices to 80% capacity in get a longer lifespan for their batteries. When my devices dip to 80%, I look to change the batteries. And I’m pretty sure that used to be apples recommendation. People limiting to 80% have the experience I can’t stand from day one. I’m glad it works for them.
…and we also need it for all iPhones. Not only iPhone 15. Would be great, will not happen. 🙄😑🤷♂️We need this for the Mac: Automatic, off and 80% charge limit. The current automatic setting works surprisingly badly compared to iOS.
So I guess this is another way of saying the battery can be overcharged... I thought battery overcharging is a thing of the past...
Because it’s doing whatever it wants. The limit is a fixed limit, decided by the user. I‘d really like to have it. But I would never trade in the size of my 13 Mini for it 🤣.Only 80% limit? Why no optimized setting?
The device isn’t limited if you don’t need to use 100% of the battery between charges. This is the crucial point a lot of people seem to be missing. If I wake up with 80% and put the device on charge at night with 30%, my experience has not been limited, but my battery has experienced less stress. Also, if you need 100% occasionally you can just charge it to 100% in those cases.
I’m typing this on an iPhone XS which is coming up to 6 years old. My next phone will last another 6 years. My phone has a minor crack in the screen which would need to be repaired in order for Apple to replace the battery. I have no interest in an aftermarket battery which probably has less capacity than my degraded battery.
It makes literally zero sense for me to charge the battery more than I need, pay for screen replacements, pay for battery replacements, when I can extend the life of my battery for free with zero limitations.
This is unusual, something is wrong with your battery.Biggest waste of time/battery power.
I used this feature with my new Iphone 15 PM from day one and after 3 months was already down to 97% after 35 cycles!
Got an iPhone SE through work over a year ago and charged it as and when needed to 100% and it still shows 100% capacity.
Too bad that it is available only on the latest iPads
Absolutely. My 15pro has just gone to 99% after 8 months..usually it would be like 95%
Always... you phone loses the water resistant ability... My friend learnt the hard way, despite having his phone repaired by Apple...2.Some don't want Apple to open their phones to replace the battery. Whenever you hand over your device and someone opens it to replace something, there is always a risk of screwing things up.
No, their testing changed but the battery remained the same type. Imagine if there was new tech that doubles battery endurance from one year to the next, this would be major news.I think the battery tech has improved this year as well, as evidenced by them upgrading the charge cycles post-launch.

In reality all Apple did was realize that their arbitrary 80% health limit can still be accomplished after 1000 cycles which isn't surprising because at 80% the battery is long done for already. No iPhone battery is in great shape after 500 cycles but it will usually still be above the useless 80% threshold.
