When are all 4 cores needed?
Ok so, i have the app Battery Doctor on my s4. It's got some cool features, but the verdict is still out on whether it actually saves me battery life.
Anyway, there was a feature added to throttle down cpu speeds when the phone is idle. Its not that intricate, it's on or off.
So i had the app running and ur able to see all 4 cores. I noticed that only the first core was doing something. For example : it stayed running around 380mhz and jump to 1600 when i touched the screen or something simple.
But i noticed that the other 3 cores remained "sleeping. " so i started running a few other apps, even started up a game with the other apps running in the background, went back to battery doc, and STILL only one core active. The second core jumped for a second or two, but that was it...
What i DID see is my active app widget turn red(bad).
So what the hell is up? When do the other cores wake up and do something??
Sure, maybe it was a misreading from the battery doc app but like i said, i did see the phone start to get bogged down.
Is this normal? Bc it's got me wondering if this may be the reason my phone gets unbelievably hot...
