I have read reports who says more than 1000 shots on one charge... No further details.
That sounds awfully high, and with no further details, I would be quite skeptical.
I am also aware that Li-Ion chemistry should not require discharge-charge cycles, but never the less, most users get improved battery life after a few recycles. As I wrote, I suspect it could be something with cell alignment.
I don't know what you mean about 'cell alignment.' A discharge cycle simply recalibrates the battery level indicator in the camera (or laptop or whatever) to match what's actually being reported by the battery, instead of shutting down prematurely.
