    Default peripheral vision reacting quicker?

    ... dunno where to post that question, so typing it in here ...

    When using my "typical" Li-Ion cell charger, I notice that:
    * when directly looking at it, I can notice that there is a short interruption in the red led lighting (when the charger checks voltage) but can not say more, but
    * when looking somewhere else, I can clearly say, that in between the red led light, the color changes to green...

    is peripheral vision "quicker", than focused?

    Yes. Peripheral vision relies mostly on rod cells, which transmit lower-bandwidth greyscale video to your brain. Peripheral vision (including the miniscule amount that's actually in color) is given a higher priority for processing as well, because it's used to detect nasties sneaking up on you in the dark.
