how can i lower my cpu usage, constantly at 50%+

[grondinm]

i think people are confusing the % that the htc task manager gives you....it shows mem usage not CPU usage...that is usually around 30% or so with nothing running....CPU usage you can see by using dotfred's task manager...these are 2 separate thing...my actual CPU usage with dotfred running is about 12% so without it it's like 3% max(with nothing else running)
