I've had mine for well over a year, going on 18-20 months I think, and I really havent noticed much in the way of diminishing battery life.
I don't use it as often as before for as long a period of time, not commuting the same way, so it doesnt really get the same usage except when Im working out or going on a long road trip, but still works pretty well in my opinion.
Anyway, I wouldnt use any other player, its just the best.
