How does Sturdy work against False Swipe or Hold Back?

Question

Basically, does a move have to deal more damage than the opposing Pokemon's HP to make it activate Sturdy? Or a Focus Sash?

Answer 1

A move has to deal equal to or more than a Pokémon's max HP to activate Sturdy, and it has to be from full health. False Swipe and Hold Back always leave the target with 1 HP regardless of all other factors (stat drops/boosts, crits, etc.), so Sturdy is irrelevant in this scenario.
