I was using Cyanogen RC3 but the battery drains really fast
20% of the battery gone when i turn my milestone standby for 6 hours
setCPU has been used for 500/250 during screen off
help....
Hmm.. I seem to get the same mileage as I did with 2.1. Maybe try uninstalling some apps? For me setCPU is set to 250max when screen off for me. But I really don't think that changing those values effect the drain that far off.
Maybe you could try reflashing if anything else fails?
Cheers
