Battery drain and handsfree problem

Hi, i have a custom rom android 4.4.4 KK pacman dorian's build and i have 2 issues.
One of them is that my phone battery is draining fast..i've turned down google location...i reinstalled the android but...it didn't work
Another one is that i can't talk on the phone with the handsfree. Is there any solution to fix that?
Thanks.
