Same. I don't feel the negative effect of jailbreaking. I run Lockinfo, HTC Plugin for Lockinfo, SBSettings, Winterboard with nexus neuro live wallpaper on both lockscreen and homescreen, OpenSSH, BiteSMS, and I'm sure I forget a few.
I don't feel much difference from before I jailbreak my iPhone. During a few of my tinkering sessions of about 2 hours each, battery has gone from 100% to around 75%. However, I think this is understandable as during the 2 hours of tinkering, I'm constantly downloading from Cydia or SSH, removing applications, and the countless restarting of the springboard while trying different tricks and combinations.
On daily usage, I rarely drop into the 50% battery range by the end of the day.
