I was wondering if anyone can confirm the following for me. I have an AT&T Galaxy SIII running Samsung's stock Android 4.1.2 ROM. The phone is not rooted, it's 100% pure stock. My question is does this phone's CPU always run at max speed unless the CPU Power Saving option is enabled? I'm asking because when running Cyanogenmod 10.1 M1 I get significantly better battery life and I'm wondering if Samsung's stock ROM is not automatically adjusting the processor's speed based on workload like I'm assuming Cyanogenmod does. My phone has a 4500mah extended battery and with Samsung's stock ROM the battery is down to 20% after 10 hours even if the phone is idling with the screen off most of that time. With the previously mentioned Cyanogenmod ROM my phone's battery is down to 55-60% after 10 hours. Can anyone confirm this behavior?

Get better battery stats. It will show you what is draining it so fast.

you did not read the OP did you....

He said he is bone stock. therefore no custom kernel, no root, no over clocking ability.
