yeah. i use siyah 2,1,1 with smartassv2. i got 50% left after 1 day and 5 h, 1h 50 min display. and AOS at 3%, but even when used speedmod, i got AOS at 44% or higher, the battery lasted 2 days. so i wouldn;t worry to much about it if it lasts longer than 24h.
flash siyah , used setcpu, smartassv2. and see the results.

it is posible . i got 2 days , 4h screen on time. and had 12% left. depends how you use it. what's the signal, and other stuff. but it can be done.
There are a lot of factors involved. First of all, what ROM, kernel and modem you use, what governor and CPU settings you have. Battery is also affected by how many apps you automatically synk and how many are set to refresh periodically. Signal strenght in your area is also affecting battery life, as well as some settings, like brightness level (obviously), HSPA, 3G or EDGE, how many e-mail accounts you sink etc. I am sure there are many more i miss right now.
For example, I had until yesturday some serious drain with version 3.1.1. Unplugged charger at 100% and, without touching the phone, without even turning the screen on, the level dropped 10% in 2 hours.
I found out, after cheking everithing I did different since I upgraded from previous version, I found out that syncronising phone contacts with the contacts from FriendCaster was the fault. because I want my contacts synked with Facebook, I installed SNS support from Kitchen to do it and disabled the contacts synking trough FriendCaster. now everything is back to normal.
My point is, if someone experiences battery drain, ther are a lot of possible causes. So, the only way to find the cause is to digg deep, test various settings, check all your programs and, of course, do a lot of reading in the forum
