If it's considered proper to charge a cellphone only to 80%, what about
other devices that use batteries. Today I got a rechargeable bluetooth >speaker to use with my cellpphone, and the instructions say to charge
it, until the red light turns blue. Isn't that 100%, not 80%. Am i
damaging the speaker battery by charging it until the liught turns blue?
For that matter, what about people who leave their phone plugged into
the charger or sitting on the wireless charger all night? Doesn't it
go to 100% and sit there,
still charging even after it's reached 100%.

No.
The batteries have a charge controller which will make sure, that the
battery will not get overcharged.
However, you should not keep a battery charget at 100% all the time -
this is what will degrade batteries as well. But charging the up to 100%
when you intend to *use* the device after that, it should not be a
problem at all, since the charge will be depleted below 90 or 80% very soon.
As a rule of thumb: if you want to store a device with rechargable
lithium batteries without using it, you should charge it less than
70-80%. But if you want to *use* a device, you may of course charge it
up to 100% since the batteries will get discharged to "safe" levels
within a few hours (or even sooner) anyway.
For that matter, what about people who leave their phone plugged into
the charger or sitting on the wireless charger all night? Doesn't it
go to 100% and sit there, still charging even after it's reached 100%.
No. It will just stay around 100%.

On most devices, you have no control.

Most devices will limit the charge, probably stopping it.
My Motorola G52 detects that it is an overnight charge, and calculates
an strategy to have it fully charged by the time the alarm goes off. >Initially, it charges up to 80% and holds there, then charges the
remaining 20% just in time. And it knows the capacity of the USB charger
you are using. It knows I am using an 1U, thus it will charge slowly always.
If I try to charge it at a different time of day, it will charge as fast
as it can to 100%.
So, it will depend on what the makers of your phone decided for you.

I believe most newer Android devices have similar strategies implemented
and reduce the charging current to a lower level for overnight charging
but use the maximum power during daytime. I experience a similar
behaviour with my Google Pixel 6a - in daytime it charges faster than
during the night.
Which means that there could be an app to limit the charge to 80%. The hardware to do this is already in place.
