Could calculators plot battery status?
There's an interesting thread in the HP Prime forum about calibrating batteries.
https://www.hpmuseum.org/forum/thread-14125.html

It prompts me to wonder why modern graphing calculators do so poorly at showing battery status.
I'm not thinking so much of the accuracy, but the user interface.

AFAIK all calculators are limited to a 4-segment battery status icon or similar, showing instantaneous voltage.

Programmable calculators can possibly run a program to save the status, but it would be quite simple for a calculator to save the battery/time readings - most modern phones can show a plot of battery usage.

Why can't calculators plot and perform statistical analysis of battery status?

It could be useful in physics/statistics class to have real-world data without typing in data. Other data would be useful, but depends on optional data acquisition accessories.

One counterargument in a classroom setting might be that the battery usage is personal data.
