No problems so far with my PRS-505. I haven't noticed any drop in autonomy.

As battery life expectancy depends in large part on the numbers of charge/discharge cycle, E-ink reader batteries should have a very good lifetime.
I charge my reader about one time a week, and generally the battery still have some charge, so I must have a complete cycle every 10 days.

As a comparison my smartphone with a similar battery must have a charge/discharge cycle every 36H. After about 2 year, its battery is now at about 70% capacity. I will probably order a replacement soon on Ebay.

For my reader I expect the warranty to be long gone when the time comes to change the battery, and unscrewing 4 screws is no big deal.
