For Android, there are a multitude of apps, such as Wattz that will tell you the actual voltage of the battery. Full may be 4.2V or 4.35V depending on the chemistry used. ACCA (root required) will let you limit charge rates and stop charging at a certain percentage.

Staying under 4 volts (around 60% for most phone batteries) will vastly extend battery service life. 80% is a bit less extension, but still far better than charging to 100%.

i was looking for something like acca since forever

foss discoverability needs some mad work

I just use Home Assistant + smart switch

how do you do it?

Just set up an automatic to turn the switch off when the battery reaches 80%. Then back on when <75%.

that doesn't answer the question of whether there's a way to tell that their battery is limited to 80% on hardware level, though.

Unless it's lying about the voltage itself, you can be pretty sure it's not limited if it charges to 4.35V. 4.2 is a little more tricky if you don't know for sure whether 4.2 is the full voltage for the cell.
