My N9 is now consuming 37/76ma (idle/avg)
My UI is pathetically slow - seonds to bring up the keyboard.
The charge lasts less than a day (it used to clear 2 days easy, and only consume 4% overnight.)
Many built-in apps like Mail and video player bring up the "Not responding" message.
My feed area is duplicating posts 10x+ times.
My driving app search no longer works (no results) but the maps app finds the route fine.
Facebook routinely tells me "Account disabled" or fails to load photos.

Half of these issues seem to be hardware related, the other half I think are coming from software neglect. I'm thinking about ditching this phone and moving to a iOS or Android one.

Has anyone seen these issues and suggest fixes? I only have a few additional apps installed. I've loved this phone but in the last 2-3 weeks it's taken a nose-dive.

EDIT: this past weekend was my breaking point. I was out and could not get driving directions to the destination. I missed my appointment. :-/
