OK, I've done a some tests over a few days. Apparently MSN Pecan is a power sucker, the only one which works well without obvious effect on the battery life is gmail.

See attached screenshots for more info. In order:
- MSN (Pecan) + All Jabber accounts (gmail+jabber+ovi) + yahoo + skype
- MSN + ALL Jabber
- MSN alone
- gmail alone (note that one is screenshooted a bit earlier so you still see the charging period, ignore it)
- no IM at all

obviously gmail alone works well, the others suck power. AIM and ICQ don't work at all (they always say something like "network error"). Facebook-chat seems broken recently. I don't have accounts to try the other ones.

Re: Battery consumption analysis
 
My graph using MSN-Pecan 0.1.0 final (over 2G) looks pretty much the same as your gmail graph.. which pecan version is that? I'm not sure if the final is in extras yet, as mine is from extras-testing. I think there were some problems with battery consumption in the release candidate versions.

I'm using 0.1.0-0maemo2. I'm over 3G, for pecan and gmail (and everything else).

I just tried that SmartReflex hack yesteday. It worked fine, until today (just one hour ago) N900 crashed and booted.

Code:
$ cat /proc/bootreason
32wd_to
What else (logs) would be helpfull to know if the reason was SamrtReflex or something else?

I don't think there are any, but: you can be pretty sure it was SmartReflex. Many people can't enable SR without getting 32wd_to crashes.

I enabled it yesterday and had a reboot within minutes and I never get those, so it's turned back off.

I've had it enabled for several weeks now without a single crash. Guess I'm just lucky :D
