The actually additions drill resets block break progress while being recharged, which is a real pain while you're mining. From what I understand there's an "easy" fix for it. Items have a function called shouldCauseBlockReset that causes items to reset block break progress when their NBT changes. If you override it, however, the item wouldn't reset block breaking progress and therefore keeping a batter on recharge mode should be more convenient rather than just a bother because you have to toggle it on and off.
