that's not true, charging LFP to 100% degrades it just like other batteries. LFP just degrades less. but if you charge to 80 it will degrade even less. not that it matters in practice as new cars have 8 year battery warranties so it becomes other people's problem.
the recommendation to charge to 100 started when Tesla failed to read battery % from their LFPs between 80-100%. the voltage difference ws so minute between 80-100% that the car wasn't able to give an accurate state of charge giving people inaccurate range.
so they recommended a weekly charge to 100% to calibrate the range meter.
true story.
