I have the MH-C9000 (best AA/AAA smart charger on the planet) & one of it's routines for optimizing the battery (break-in mode).
Is a sequence of discharging & recharging....
It doesn't have a huge impact, but is beneficial for the LT condition of the battery.
Got to a forum like candlepower and all the battery nuts there will say the same.
However it could be that this won't apply to Li-Ion batteries in the N9, because of the controller chip & how it regulates charge.
i don't think this is something "electronic", controller driven. rather strikes me as a "chemical" feature of Li-ion.
it doesn't have a "memory effect" but rather can go thru a limited number of charge cycles
thus applying to any Li-ion battery, no matter how it is charged.

two caveats:
  • emptying / discharging the battery down to 50%, recharging it, emptying it to 50% and charging it again counts as one cycle
  • if the battery stays discharged too long (weeks, months?) it loses it "energy storing" capabilities.
i'm not a chemist, thus i don't know the science behind this but that's what i gathered from Apple & Dell's Q&A about (Li-ion) batteries
