Battery Lifetime

I just installed script, and made a menu command for it to see what it 
does to my battery. However, the phone wakes up inside a few minutes. 
Someone earlier wrote:

That's currently the crux of the problem, and why I don't yet use suspend. It 
resumes on cell registration messages, and each resume is another chance to 
fail. It also has to resume to accept a call, and not being able to reliably 
resume makes it an unreliable phone.

So is the cell registration the problem? Is it normal that it wakes up 
from susped this often, which pretty much voids any benefits atm. I know 
it's under development, just curious.
