Honestly, this is nothing FR or OM specific. Considerations valid for all
LiIon batteries apply here as well.
AFAIK, it's much more important not to push the last electron into the battery
that might fit in here, than to charge with lower current. Some notebooks
allegedly have a "treat battery nice" option, that stops charging at
~75%..90%. You could do this by adjusting the Vbat-max setting of PMU. Til
now, nobody cared about it yet.
PS: have a Nokia with a LiIon accu that's 7 Years old now, 100% uptime. Still
is good for 70% of initial capacity. So yes, obviously LiIon *can* have
longer live than just 2 years.
