> All of these devices lie to me, that I lost less than 20% of battery health. Where in reality it’s somewhere between 25-50%, and when they wouldn’t pretend that maximum output is any way a good indicator of the real battery life, aka how long you can use a device.

FWIW, I've only directly witnessed this so far on Oneplus devices, others have remarked the health gauge on these seem to use gacha mechanics where health % will be all over the place. (like >10% variability). I have theories as to why this happens, it's in firmware not OS as LineageOS shows same behavior.... but tough to really know for sure if this was by design or not.

Oh and charge thresholds only do so much, heat kills batteries reliably fast. Deep discharges under 20% or so seem to run more risk of electrolyte breakdown. Don't fear fast charge in bulk charge range, it causes less wear than other factors. I slammed the 65W charge into my 8T's and still got years of >80% battery, replacement wasn't too hard to do on these.
