One of the chart showed the life cycle for various depths of discharge which basically showed that shallower discharges allowed more discharge/charge cycles (a 50% charge cycle giving about 2400 cycles). So if you read enough each day to result in 50% battery use and plug your ereader into a charger when you go to bed you should get around 6 years before the battery reaches EOL.

Wow those are nice stats! Do you have a link to suggest so I can read more about that? Is it the same for all lithium-ion batteries? Very nice. So if I get it right, I could charge it every night and would still have 50% battery after 6 and a half year (2400/365)? Seems really good.
