Periodic creation/deletion of desktop web link nearly always drops idle consumption on mine. There have been a few days that I had to do this 3-4 times over the course of about 2 hours.

My device idle was 6mA over the weekend and about 15 now.

I've never deleted any accounts and rebooting makes it worse or so it seems for me. I don't reboot unless there is a very good reason anymore. To date, there have been no good reasons for days and days now.
