Same here - with 2 16GB A-Data SDHC cards my battery life has been dramatically reduced - nearly dead in standby overnight. Dies completely if left on longer than that. A new battery helped some - only down by ~50% in standby overnight. I suspect that the stress on the battery killed the original one. Have started to try to remember to turn it off at the end of the day - a PITA.

Running OS2008 v. 51-3 from the internal card with fanoush's modified initrd for the custom boot menu - not a modified kernel. Should probably see what happens when booted from the flash - may be that running from the card makes a difference. Will try that and report back.

I have no metalayer-crawler in the process table. Have not disabled metalayer-crawler0 in init.d or rc?.d nor renamed anything.

Update: Tried leaving N800 booted from internal flash overnight. No difference - still down to <50% battery capacity.

Estimated battery time left
When idle: 2 days
When in use: 1 hour
