hahaha, yeah seldom reply lately as there're far lots developers within the droid world...
some suggestions for whoever using the Perseus Kernel:

1. You can get 100mv UV for all CPU and GPU and Memory (stable with >1 month used)

2. UV for CPU on 200MHz can safely UV down till 750mV (>100mV compare to other freq)

3. You can set your CPU hotplug for the 3rd and 4th core to be turn on when @1100MHz, this will direct force you CPU just use max 2 cores whenever you switch to Power Saving Mode (good in critical power saving needed)

4. You can further power saving by install the Android Tuner (get it from Play) and set the Active Tweak on the Screen Off behaviour the max freq when screen off to 1GHz and with this mean whenever u switch off the screen the CPU will work max 1GHz and with only 2 cores active (you need to set the #3 above on hotplug)

5. If you no need immediate social/mail update then you can use the Deep Sleep Battery Saver (get it from Play) and set to use 30mins on for 1mins (Gentle Profile), this will help A LOT on the 3G/Wifi data power comsumption.

With all the above you can easily out last your battery for max without having major impact on performance.

If all above apply you should seeing your batt will drop ~1% per hour on wifi in standby and ~2% per hour on 3g data... what I say here is MINIMUM and from what my usage my batt drop ~1% in every 2 hours on wifi and from 9AM till 6PM (9 hours working with normal minimum usage) my batt fall from 100% to 94%...

Tested the GPS navigation with 3g and BT on (screen brightness about 50% with auto on) I get ~5%~6% drop in 30mins using the Papago and calculated easily can get >8 hours active navigation time...

Hope these information usefull for some battery geeks out there...
