What's the deal with ereaders and their seeming disdain for sane battery life measurements?

Amazon boasts "up to 8 weeks on a single charge" in all their selling points, then, in the fine print states "A single charge lasts up to eight (8) weeks, based on a half hour of reading per day with wireless off and the light setting at 13".

So, it has 28 hours of actual use time, got it. Why not just say that?

Because people are dumb and don’t want a book that you have to recharge every day.

But also because it is not really 28 hours of battery life. If you just let it sit without touching it, the battery lasts for several weeks, if not longer.

It's a hard class of devices to give any sort of reasonable battery life length.

Regardless, the battery on these devices even back in 2012 was already good enough.

With light at 13 it won't last weeks. Not even 3 days.

Why would you leave a Kindle untouched with the light on for 3 days?

Because we're discussing battery life with the light at level 13.
