Default A little problem after update latest Kitkat

After i updated latest kitkat i got little problem

When i receive a message from messenger my HH still awake until i open it or push unlock button
this make my handphone drain my battery, makes my HH overheat until 45 degree, where im not using it.
but this problem only happen in sview, when i open the cover is normal

once in the night my HH have 70% battery after i wake up my HH only have 7%battery, i expect because i receive a message and my HH awake all night, not only when i receive message also when i got notification
heres my consumption battery
