Battery draining fast after kitkat update

[sunny sharma13]

Hi,
My smartphone's battery is lasting only for 6-8 hrs after kitkat update while earlier it used to last for 1 day with the same use.
The difference I notice is screen is using almost 40% of battery after kitkat update and earlier it used to use 16-18%.
I've tried wipe cache also but no benefit.
Can someone please help me how to resolve this issue?

Thanks in advance

Just to clarify, you wiped cache in recovery?

yes, I've done the wiped cache in recovery mode.
Another thing I notice is that screen becomes hot after using it for few minutes
