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
