For lithium batteries (phone batteries) it’s actually more important than draining to 0. Many studies indicate that the average phone battery should last several thousand cycles while only losing 5-10% of total capacity provided it is never charged above 80%. Minimum % (even down to 0%) and charge rate below 70% is also unrestricted.
The tl;dr is that everytime you charge to 100% is the same as 50-100 charges to 80%. Draining a lithium chemistry battery to 0 isn’t an issue as long as you don’t leave it in a discharged state (immediately charging).
16% is pretty good. the ones at three to one percent are the weirdos.
To prolong your battery’s lifespan you shouldn’t let it drain below 20%.
Also charging it fully but I don’t know how important that one is.

Just as important. And most phones these days have a setting to prevent it from charging to 100%. E.g. I set mine to stop at 90%.
Don’t phone battery indicators lie to you now so that 0% displayed is actually about 20% specifically because of this?
I really hate and avoid when my phone switches into battery saver at 15%, so in my mind 16% is like 1%
