Are you using TaskKiller? I use it to monitor "suspicious" services on my Adnroid. That helped me to disable many "old" apps that just run-out my battery.
I used to use TaskKiller for memory clearing purposes. Haven't used it since I upgraded to CM 10
I am working on data sync service, mainly sync data between cloud and mobile. 30% of apps installed on my Android do data sync. This thing is killing battery.
