OT. Typical USB A/ USB C power banks from Anker, Rav, Aukey, Xiaomi, etc

For all you battery nerds out there, how accurate or not is the led light status on them ? Charge indicator...I have a few. If I'm not traveling, my larger power banks are not used as much I try to keep the SOC at the 75%'ish charge level on the powerbank (by simply gauging the led indicator on the unit itself). Not very scientific or accurate I know. Be curious has anyone confirmed done any rough testing to confirm how accurate the led charge indicators were if not the =on board charging circuit/algorithm= and the charging cutoffs, etc.
