Last year LG came out with an advanced battery tech that increased the numbere of recharge cycles on a Lithium-Polymer battery to 800 charge cycles but I doubt they're using those in e-readers. And don't forget that simple age also diminishes a battery's life.
But with the frequency of charging an e-reader normally sees we'ree still talking about years of use without any huge impact on performance and would be almost impossible to get that bad of a performance.
Also the reason batteries enter into the consumables category is because they do have a limited lifespan based on usage. It can still be faulty though and should enter under warranty if it's obviously disfunctional.
You can also argue that if it's dropping that much in standby it is not actually a problem with the battery but rather the device which isn't properly powering down while in standby and is therefore warranty covered issue.
