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?

TBF phones and computers also take "evocative" numbers on their marketing material.

The "Up to 33 hours of video playback" for the iPhone Pro Max[0] for instance is an absolutely insane use case (nobody's letting their phone passively play local videos for a day and a half), and gives little insight into how long it can stay in sheer standby, do video meetings or handle slack.
