It shows that your phone except for the two spikes is not sleeping. Is the charger connected? Which apps are you running, since you have a very high cpu load. To measure if sleep is working turn the phone on with no running applications and check the sleep stats after ten minutes with mce or SystemDataScope.

Regarding the Mac problem, is everything fine when you use Android?
