The new battery patch uses new profiles based on default voltages. To use Karam's custom profile, save it to /home/user/.kernel as something meaningful (name it what ever you want as long as you remember its name, then edit /opt/dbus-scripts/cpu_normal with what ever text editor you want. E.g.

Nano /opt/dbus-scripts/cpu_normal

Now change the line that says kernel-config load overclock to
Kernel-config load *Karam's custom profile* (I.e. whatever you have named it).

Now when you unlock the device it will use that profile instead.

I am unsure what difference the cpu governor actually makes (not seen much difference on my device) but if you want to change it, edit the profile you have set to overclock (E.g. nano /home/user/.kernel/karam) and change GOVERNOR=ondemand to GOVERNOR=conservative and see if you get better continuous usage.

I must warn you though, if you are unsure about anything here, you are probably best to leave it. You could end up giving yourself random reboots if your kernel profile is not set correctly. Although, you can just go back to using overclock in cpu_normal which should fix it.
