Is “overcharging” electronics real thing and if so why is it bad for them?

Yes, overcharging is bad for batteries. Even just charging to full is bad enough to avoid if you can. Even if the device isn’t actually overcharging when plugged in, keeping the battery topped off at 100% isn’t great for longevity.
Some devices have built in protection. Certain android phones have settings to stop charging at 80%. Or it’ll keep it 80% overnight then charge to 100% before your alarm. Windows 11 can detect that you’ve been plugged in for a long time and discharges the battery to 80%.
I think some electric cars will just lie to you. When it’s brand new, 100% is actually 80% (for example). The extra 20% is locked away until the battery starts degrading and you need the extra capacity to have the same range.
