I didn't find any app for tracking charging cycles.
So I'll make some notes manually:

Sunday 11:35 pm to Monday 02:05 am CET = 2.5 hours, down from 100% to 77%.
WiFi on all the time. Mainly checking news, browsing the web. I've read articles about half the time, which should have low battery consumption.
23% down in 2.5 hours. This would indicate close to 11 hours (linear extrapolation, which isn't correct of course) of total battery life. I'll keep track. First impression: The more time I spend reading, the longer the battery seems to last. No surprise here, that's what most of you stated (and which is not my average usage pattern. I don't read books on iPad, only news and magazines).

Ongoing: (Between sessions leaving iPad in standby, not turning it off)
Down 23% in 150 minutes = indicating 10.9 hours. (Reading a lot)
Down 29% in 175 minutes = indicating 10.1 hours. (Downloading a lot)

Before going to bed a quick check: While in standby, in 1 hour iPad has lost 2% (may not be accurate of course). That's surprisingly high. Some of my ePaper readers can conserve battery for weeks in standby (whereas others run dry within a week, due to faulty standby mode).
