@jpala16
you can check the percents left in conky
time for about 10 minutes and check the conky before
and after
you will notice without batterypatch each 10 minutes 4% are gone
now each 10 minutes 1or2 % are gone (this is in my case you might have different results)

@WhiteWolf
i haven't tried the new CSSU update
but the problem is probably with the voltages
edit the file /opt/dbus-scripts/cpu_normal
and change kernel-config load overclock
to
kernel-config load $the profile which is stable with u

but the default custom profile with batterypatch are the best for battery saving
