Battery health

I need suggests at what percentage should I let my iPhone11 Die and then charge it
Most people say not to let it go below 40% and not higher than 80% when you charge. I’ve also read somewhere that unplugging between the 50-60% range is actually beneficial for your battery. No principle yet when it comes to battery care, but not doing full charge cycles each time makes a lot of sense.
