Li-Ion battery life optimization is complicated.
2
There are MANY factors involved, including how close to 100% you charge, how low to 0% you let it go, how quickly you charge, the temperature, and the electronics built into the battery charging circuit (which can be very "smart"). All these combine to make it impossible to predict how any one action will impact battery life - except for one: overheating will damage the battery structure and ultimately reduce battery life.
Charge the phone in a way that works best for you - if you spend a lot of time worrying about "optimization" you will be spending a lot of effort for a tiny (if any) improvement.
But avoid overheating.
