From my experience, 23071/75 builds have terrible battery life.
My phone would die from a full charge over night.
I got a hold of SYS 23081 and battery life seems to be very good.
Using
nuePowerCPL after a fresh restart.
23081 had the following discharge rates:
125 mA on wake
75 mA on idle
57 mA on dim
13 mA during sleep*
*When my phone woke up, it showed 13 before jumping to 125.
I tested with titanium only and then with SPBMS3.5.
Both tests had the same numbers.
Feel free to compare with what you have.
