The author of this one hasn't done much research I guess. The damages claims haven't really dropped at all:
1. Damages are merely the consolation prize. They want an injunction, not damages. With an injunction they have google by the balls, and can demand a license fee *per phone* plus damages. $20 per phone, over the lifetime of android or the patents? If google sell a billion phones that's $20bn. Plus the damages.
2. The previous damages figures covered a different time period. Like, the lifetime of android. The new figure is for *past* damages only. Future damages are likely to be bigger than the past ones
