I'm looking to get some tips on how other users utilize their governor / CPU Policy in order to gain performance and increase battery life.

I've installed Diablo Turbo, but have not done anything to change governor settings. Does this mean I'm using the default setting --- which would be on demand, right?? I basically understand what on demand, conservative, and performance do, but what does null and powersave do?

Currently I am rotating 2 OEM batteries using an external charger so that when one is drained I shut down my N810 and swap it will the full one. This is basically the only time I ever shut down my N810. The rest of the time I keep it in offline mode whenever possible, and keep bluetooth and GPS turned off virtually all the time. When I'm not using it I keep it in offline mode with the screen and keys locked. So far I'm happy with the battery life, but if I can use the CPU policy to increase it even more than that's all good. As far as performance goes, I'd love to have more if possible when internet browsing.

I'm not great with terminal, but I know there are different GUI options for changing these settings ---- ASUI and Advanced Power specifically. Do they both set CPU policy the same way? Does it matter which one is used? I don't use SSH or VPN so I don't necessarily need all of the functionality of ASUI, but I understand it is more efficient than Advanced Power.

Any tips or suggestions would be appreciated. Thanks!
