I believe the underclocking is more a placebo than anything. If the phone is actually going to sleep when you turn the screen off it will go into a lower power state mode than even underclocking will. During the NBA finals I was sending text messages constantly throughout the games so about 3 hours there, alot of browsing forums using tapatalk, and newsrob, some web surfing and some light phone calls. Overall I can go 24 hours on a charge with that kind of use. I still charge it everynight because that's how I'm used to my smartphones by now.
