One, do a wipe and re-install from backups. If the device doesn't really have much of importance on it, just wipe it and start fresh.
Two, discharge the iPad until it shuts off, then fully charge it and leave it plugged in for several hours after that. That will update the battery capacity gauge.
You can see the internal battery stats by plugging the iPad into a Mac and running any of a couple of different utilities - one free one is coconutbattery.
My point being that you can't really change those batteries on demand.
Something tells me you're not really being honest with us, for the sake of a "apple suxx" story.
The battery health is also included occasionally in the analytics the iPad sends to Apple if you have sending analytics. In Settings go to Privacy & Security/Analytics and Improvements/Analytics Data.
That takes you to a list of various recent analytics files that have been sent to Apple. If battery health was included it will be in one of the files "log-aggregated" files (iPadOS < 16) or "Analytics" files (iPadOS 16).
Battery health isn't always included in the analytics uploads so you might not have it in any of the files. Then you just have to keep checking as new files appear.
Here's a video I found talking about this [2]. The author of the video has written a shortcut [3] that shows up in the shar sheet. When viewing an analytics file you can share it with that shortcut and the shortcut will try to find battery information in that file and display it.
I just gave it a try but my logs don't currently have health information so I don't know how well it actually works for that. It did get cycle count from my logs and that matches what Coconut Battery shows.

If you have a charger at your desk/car then honestly you could likely go even longer.
I've seen people struggling after 2 years though so it's rather random.
Just a random N=1 sample for you
That was with a few hours of screen time - I found that it didn't matter to me because I'd just plug it in at home/work. I'd call it "servicable" but certainly not great - but for 5 years I was personally surprised.
Why will I replace my phone if it's in just fine working condition and is sufficient for my needs, that too in just 4 years?
Battery replacement will work well for me once it's below 80%.

> This hasn’t worked for lithium batteries, partly because so many formats exist. “These batteries are all over the place in different sizes,” he said. A related challenge is that the technology for lithium batteries changes rapidly — every one to two years, he said.
(edit: I found a working link to the article: https://link.springer.com/article/10.1007/s41745-021-00269-7)
Apple is not throwing lithium batteries into landfills, and it is the one doing the replacement. Tesla is definitely not doing this, so what is left?
Probably those lithium rechargeable batteries you can buy on Amazon?
If you say that the comparison isn't relevant, I'll say yes: the whole point is that the industry has been innovating for computing power and computing power only. Cheaper versions exist to target low price. But no work is done to target long battery life because it's not considered profitable.
1) Firefox on mobile, with addons. Battery consumption is reduced a lot with less javascript, less ads downloaded, less domains contacted etc. From my quick tests, Firefox was perhaps efficient as a default installation compared to Chrome, or on a wifi with a pihole/nextdns type setup. But out and about in the world
2) Downloaded videos, podcasts, music or books. If I store my stuff on the device by downloading at home on wifi, it uses way less power than streaming over mobile data. My battery lasts for really long time playing videos from storage compared to for example Youtube.
I often wonder how much the battery life of a phone is a function of battery size and phone cpu & screen technology, vs web technologies and website design/performance. I can sort-of control for the latter.
I also find Brave a lot simpler than Firefox + installing add-ons, and it uses uBO lists by default which is mostly what I care about.
Not how long battery lasts before needing charge, but how many years it lasts before dropping to say 80% of original capacity that it needs to be replaced or the phone needs to be updated.
Most, if not all, modern phones are performant enough that I won’t need to update for a long time, if not for the battery issues. At least for my use case.
