I want to know how to underclock or undervolt my phone so as to slow down battery drain. Please help. Setcpu doesnt work - I just discovered that it's one of those fake processor apps.

You need a kernel that supports underclocking & undervolting. Assuming you have such kernel, use No-Frills CPU Control app. It can underclock your CPU, gives you some statistical data about clocking frequency & change governor & I/O Schedular.
I was previously using SetCPU on my phone, and it worked fine. Probably you didn't have proper kernel (plus HTC devices have Perflock) or app may be incompatible.
