Had not read anything, it had been on the screensaver the whole time and the backlight was at 0.
The useful lifetime of a Li-Ion battery is very hard to judge.

Depending on use patterns (depth of discharge, frequency of re-charge, price of tea in China) their storage capacity can degrade, and perhaps faster than expected.

So what you are seeing may be "normal" -
What is your nominal temperature where the device is kept?
How old is the device?
How often do you recharge it?
How low do you let the capacity fall before you recharge it?
What are you recharging it with (slow: USB port, fast: wall charger)?
How often and long do you use it over what period of time between recharges?

Indexer related questions (*)-
How many books are on it?
Have you added, removed, or reorganized them recently?

(*) the kindle is normally very close to off (most of it is powered down, not running) -
Even while reading a book (it wakes to turn the page, or when the beer gets warm).
But the indexer and anything else that keeps it "awake" more than usual will show in the time between when a recharge is required.
The Kindle has about 4 hours of "runtime" on a good, full capacity, fully charged battery and you are seeing 2 days.
