Aren't SSD's over provisioned in this manner? You sell a drive with a terabyte of storage, but actually ship more than a terabyte of chips in the case to accommodate degradation over the life of the device.
Because the last time they tried "silently manage the battery without the user being part of the decision" it didn't go over real well?
Some EVs do something similar: the Nissan Leaf, when the battery gets really low(and I mean it, far past the point where you lost all percentage and mileage indicators), will enter a reduced power mode (or popularly called "turtle mode"). This allows it to eke out a few more miles out of an otherwise mostly dead battery. There is a "turtle" that lights up on the screen, maybe Apple could just do that.
Turns out batteries hate when they are almost empty and you are trying to extract full power from them, voltage drops even more. So there are some compromises that have to be made.
Without power management, when a high demand task came alone and the CPU tried to draw more power, the phone would crash or shut-down.
The firmware update capped performance not to extend the run-time when the batteries were low, but to allow the phone to run reliably when the batteries were worn.
TIL. I thought I was pushing it coming home with 2 miles left…
No offense, but for me it is like the Mac is taking my hand and guiding me threw a mess. However sometimes I know the way better than the Mac but it is not letting me. It actually makes it really hard to „go my way“.
For example the “only trusted developer program“ can be run . I understand why it makes sense for most people but I want an option to decide it mysel who is to be trusted. To be fair I had to google a bit for a terminal command to fix this but either way it leaves a bitter taste. I fear that I may lose this “fix“
Now back to the battery health. Why not allow being transparent? If most of users want the 100% showing then make it default.
I think that’s what boils it down for me. Having no choice with OS X. Now I know some will say that’s how it is for Mac but do you think it is too much to ask for this (really stable) system to support choices?
"Gatekeeper", the ‘only trusted developers’ setting is a setting in System Preferences. Windows also ships with an equivalent setting in the default.
A fun side effect of this is that the tablet can boot while at '0%' battery, and then it will automatically shut off a little bit later to avoid dipping below the safe range - presumably '0%' is actually like 10% or so.
The Verge piece on this says that this is what will happen.

I seem to remember it being something like the hardware capacity is one number but there's a software upsell that you normally need to pay to unlock full capacity. But it may have also been a "we'll push the normal operating parameters to give you this extra boost", don't quite remember.
This whole discussion is colored by confusiin between the heavily simplified model presented by the charge indicator with the raw battery properties.
Fun fact: there is no "80%" level either as seen from the battery controller POV, that's just a forecast about how much energy the battery might be able produce if run until the cut-off level (and the 0% level here is also a fair bit above the chemical empty state), and the battery controller is constantly updating its model about how the battery behaves when discharging to keep the forecast accuracy reasonable when the battery ages. When the batteries come from the factory, the calibrations for 0%, 80%, 100% are at certain voltages, and they constantly move throughout the life of the battery. (Maybe not the 0% voltage)
Besides that, we have proper units for binary multiples: KiB, MiB, and so on. I've only seen KDE use them properly so far, and it's a shame.
Approximately 0 average users know about them, and of the technical users, only the truly irritatingly pedantic are going to use them (which may be why they've shown up in Linux).
Calling it a a "2 TiB disk" when it's actually a 2,000,000,000,000 B disk would be a blatant ripoff.
