Just got my BLF A6 in the mail now.
Does the Half Press really wont feel even a light click or I should feel the end of the half press before hearing the very audible Full Press Click? Its not the same with the Nitecore MH20 Half Press where you’ll feel the end of the half press before finally hearing the audible long press click? Thank you.
You just push it far enough for the light to go out. You will not hear or feel a “click” with a half press.
I received my BLF A6 a few months ago, and it’s “barely press” to change brightness. If I hold the light with 4 fingers and lightly tap the switch with my thumb it will change.
Thanks pilotdog and jch! Great to know my unit is ok. If I turn on memory mode, will it use or drain the battery even if its the light is off?
No, the BLF A6 uses a mechanical switch & not an electronic switch, therefore when it is off it is Definitely OFF. So NO battery drain when it is Off. 
Best Regards,

It won’t use power when the mode memory is turned on.
Usually flashlights with mode memory store the last used mode on a tiny computer inside it called a microcontroller, which keeps the information it’s told to remember safe even when it loses power. The technology to store information without power made it onto modern microcontrollers. The type of flashlight you’re using also has a type of switch called a mechanical switch that completely cuts the power when its turned off or even in its half-press state.
One fun fact is that this flashlight can’t tell the difference between a half-press or a really quick on-off toggle if they’re both done as quickly as each other because of this.
Thanks! I thought its like the nitecore tip when in lock mode it has parasitic drain. Even the ec11 when fully turned off has parasitic drain.
Nope, thank goodness. When you physically break the electric circuit —- mechanical switch, or unscrewing the tailcap far enough — there’s no current flowing, so no parasite.
Any electronic switch is —- depending on how well the electrical engineer/designer/circuit builder did their jobs — going to take at least a little bit of current flow.
And the bad ones suck battery power right fast.
