Nope, didn't find the time to do the expected >500 charge/discharge cycles ;-)
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.
