Default [Q] Does P780 enter deep sleep mode while charging?

Hi all. I wanna ask does your guys P780 will enter deep sleep mode while charging? Because mine did not enter deep sleep while charging, CPU frequency constantly runs @ 497MHz while charging, but if unplugged it will enter deep sleep mode. Just wondering is it normal? By the way I am on stock Vibe ROM 4.2.2 but rooted. And what's the temperature of your batteries while charging? Mine staying @ 45C while charging which is quite warm, ambient temperature is around 29-30C.
