Why doesn't my AirTag show battery level in Find My?

I believe this was changed with a recent firmware update. Mine used to show battery percentage at all times, but now only show when battery is low.
However my third party Find My trackers do still show battery percentages at all times.
My personal uneducated guess:
Inspecting the CR2032 battery discharge curve, it looks challenging to accurately determine the battery level simply by voltage.
Taking different ambient temperatures into account, it seems difficult to even get 20% steps right.
But at the curve's end, the decrease (voltage drop) is significant enough to push a substantiated "low" warning.
Perhaps the AirTag percentage readings were too inaccurate and Apple therefore chose the safe way out.
EDIT: AirTag specifications list the same temperature range as stated in the graph which is automatically accompanied by notable readout fluctuations:

It's probably not a bad idea to set a reminder to replace the battery every 12 months. By the time the low battery warning appears, the AirTag may not be functioning reliably, and worse, the battery may be low when you are trying to locate the AirTag.
Yeah I just bought a new AirTags and I’m dying to know how much battery it has left.
To give you an idea just how late you guys are to the party: #127
iOS 15.6, July of last year was when Apple removed that from AirTags. (note - licensees may still support it - Chipolo does).
Obviously, Apple decided it wasn't accurate enough, so instead only sends you the low battery notification.
The CR2032's are about $1, so I wouldn't waste any more cycles on this.

Ha ha true. I only bought AirTags last week because of iOS 17 family sharing (though I still have no use for that feature since I’m always with my wife so AirTags would never ring). Have to buy them before Apple change to rechargeable batteries next version. 🙂
I wouldn't want a rechargeable version. You would probably need to charge them every night like an Apple Watch! 🤔😬👀
No you wouldnt. A CR2032 is still just a 3V DC source with 210mAh of capacity. Adding a rechargeable battery of the same spec wouldn't suddenly make the AirTag consume any more energy.
I guess your post is intended to be a joke, but just in case it isnt...
How often do you think it would need to be recharged? Would a rechargable battery give you the same days/months of use as a standard CR2032?
Most rechargeable CR2032s are around 40mAh. So 1/5th of the lifespan of a non-rechargable lithium cell of the exact same form factor. You could use rechargable CR2032s in Airtags today provided you used your own external charger.
If Apple were to integrate a charging circuit into the Airtag, they probably wouldn't stick to the CR2032 form factor, so the lifetime of a standalone rechargeable Airtag would just depend on what kind of chemistry/capacity/size of the cell used internally.
So instead of just dropping my AirTag in my suitcases and only caring about it when the warning pops up, taking a couple of minutes to change the battery, I would have to remember to charge it monthly, charge it just before a trip.
No thanks.
Why monthly? I travel a lot. Have an AirTag in my wallet and back-bag. I change the battery like once a year?
1/5th isnt one month, but, okay.
Remember, i was responding to whoever said an Airtag would need to be recharged as often as an Apple Watch, which is not true either.

Rechargeable. Every month or so. before your trip to be safe. As opposed to the current battery that you change once a year. Rechargeable are great, depending on the application. An AirTag is not a good use case.
Fine, every 2 months.
Right now, my AirTags sit in my suitcase in my storage locker. Once in while, one tells me it needs a new battery. With rechargeable, I would have to constantly keep it charged.
