Nothing like some decent metrics to prove a point, eh Good for you.

I would consider around 85% to be about right to be honest. Even if we assume the Kobo batteries operate to specification and held 100% when sold, you cant account for deterioration through charging or usage patterns in the year between manufacture and you aquiring your device.

The sudden drop off at the end is precisely what I am seeing too albeit using the shoddy battery meter as my guide. Twice now it's indicated a decent % of power available when less than 12 hours later it had fallen below the charging threshold.
