Tesla Wall Charger Question

You need to configure Wall Charger itself. It should be set according to the wiring gauge used and circuit breaker.
It doesn't really matter what amp you choose in the app in terms of the battery life. Level 2 charging is not going to hurt the battery.

You can reduce the charging amperage if you want but this just extends the charging time and is slightly less efficient. There is no evidence that charging at Level 1 (120V) or Level 2 (240V) at any amperage up to 48A will any cause measurable battery degradation. Most battery degradation is due to the battery aging, especially over the first 5 years.
The option for reducing the charging amperage is there in case you repeatedly encounter an issue while charging that trips the circuit breaker. This can happen when charging at Level 1 (120V) using a circuit that is not dedicated to charging the Tesla. When charging using Level 2 the circuit should not normally ever be overloaded, trip the breaker. When using the the Wall Connector the circuit is dedicated (by code there can be no other equipment sharing the same branch circuit.) If properly configured during installation the Wall Connector will never enable the Tesla vehicle to exceed the maximum charging amperage, 80% of the maximum amperage for the circuit. If there is an overload that trips the breaker then there is an issue with the wiring or the Wall Connector is faulty.
