Apple devices are generally very resilient to cellebrite methods regardless of lockdown mode. Especially recent ones (11 or newer) with even slightly old iOS versions.

Even when brute force attacks can be loaded onto their phones, they are incredibly slow (like 75 attempts per day) and very unlikely to get a 6 digit code. Lockdown probably helps prevent a brute force from being loaded, but it’s mostly moot currently.

And most recent devices can’t load a brute force client regardless of lockdown.
