Recent iOS updates turned off the throttling of phones with old batteries. Apple initially said this throttling was necessary to prevent unexpected shutdowns of older phones. Now that the throttling is gone, have we seen a rash of unexpected shutdowns?

I haven't heard of this happening, which leads me to believe the excuse was bs in the first place.

EDIT: To be clear, I know that iPhones have always been known to unexpectedly shut down. Throttling performance was ostensibly meant to prevent these unexpected shutdowns. My question is whether or not the incidence of unexpected shutdowns increased once Apple lifted the throttle.
