    This is centred on electric vehicles, but the Li-ion chemistry is
    generally the same as in out devices. (ish - some recipe's have
    different Ni amounts and crystal structures).

    The best way to "kill li-ion batteries" is to start with too small of a
    battery capacity, which will cause the number of charge/discharge cycles to skyrocket - all else being equal.

    There's really nothing more important than capacity, but once you have six
    or seven amp hours of capacity, then you can start doing the little things.

    Most phones nowadays only need charging once every few days before they get
    to about fifty percent but don't go a week where it will drop below 10%.

    When you charge, just employ any of the existing native intelligent charge limitation settings that both iOS and Android have had for a few years now.

    I've discovered "low power mode" which runs the (samsung) phone with
    just a few chosen apps on the home screen. It's currently saying it can
    run for nearly six days on 62% charge.

    The point of the video is not so much stretching a given charge for
    hours of use as adopting charging (or storage) strategies that prolong
    the overall life of the battery.

    Nevertheless you can prolong the life of a battery by using it less.

    Prolonging the life of a battery that started as too small a capacity is
    like prolonging the life of a pair of shoes that started 2 sizes too small.

    Nowadays most smartphone batteries are six and seven amp hours, so you
    don't even have to *think* about prolonging their overall life as the
    number of charge cycles for a 7 amp hour battery is less than half the
    number of charge cycles for a 3 amp hour battery (all else being equal).

    You put it on the fast charger that was in the box only when it needs it.
