Set charging limit to 96%, and the phone still charges to 100%.
Tried setting it to 97%, and it still charges to 100%.
Running NSTools, and same thing.

Edit: have run this with stock ROM and the latest CM9. Works 100%, using:
sio/interactive/generic hotplug/SQlite/Turn loger off/Enable fast USB charge and 384/1344.
