I wouldn't know to be honest, I've only ever used mine with the original charger and generally let it run down before recharging it (not intentionally just the way I use it I don't actually plug it in very much unless I'm relying on it at a Disco gig when it's playing lighting controller, then it's plugged in the whole time .
This is mine at 14 months old - a lot less cycles than yours however!! My SP3 is not used daily.
EDIT : just realise the previous screen shot was not yours and a 435 cycles was still giving good performance
