Have had fewer wifi drops on the few remaining I have. So far no noticeable improvement in battery life for the most frequently used after firmware update; it is lasting at best one day before needing to be docked. Also, all of the remotes have a 'waking' message dialog that shows up for 4-5 seconds when using for first time after a longer period of time with no use. That has to be new as wasn't getting that message before.
