Not like they are just using battery voltage for SOC, they are coulomb counting with a shunt, so you only need to charge to 100% once in a while to account for drift.
LFP gets 2x the cycle count at 100%-0% as a NMC does at 80%-20%. Due to its lower cell voltage it has less voltage driven aging than NMC.
Elon: "I’d personally slightly opt for iron pack, as it wants to be charged to 100%, whereas nickel prefers ~90%."
