At 1200 cycles that's 600 weeks or about 11 years as a rough worst case estimate.

(Kudos to John F for referencing Battery University. Good source of factual information.)
Just to make sure I understand, 1200-1500 is half charges (according to battery U), which equates to 600-750 full charges?

And that is the 50% number. if you recharge at 25%, you are at 500-625 full charges, and if you charge at 10%, you are at 375-470 full charge cycles.

The 10% number is interesting, to me, in regards to the Oasis: a lot of short charges because people are saying they put it in the cover when they set it down.
