Android OS and Android System eating battery on Nexus 6P

Hi everyone!:)It's my first time posting here. I have a problem where everyday I have been getting both Android OS and Android System at the top of my battery stats.
I am running the Android N Dev 5 and getting less that 3 hours of SOT. The phone is only 4 months old.

I have tried to clear the cache and only did a factory reset only once. The reset helps a little but then creeps back. The cache clearing doesn't make a difference.. Something is eating up the battery and I have yet to try to place it on safe mode and hunt for the apps which I find such a time consuming process.

I attached a screen shot of my battery stats. I unplugged it at 11 and connected to wifi, fell asleep and woke up with 85%. Left for work and that's when I started using Data. I see that there are dots at the awake even when was asleep. It's odd and frustrating as I expected to have good battery life on the 6P but was bellow average on 6.0.1 and with N was better but not great.
Its a new phone of just 4 months and am just so tempted to have it checked out.

Any suggestions on the software side of how to fix this battery drain ?

Thanks :fingers-crossed:

CM11 Google Services eating battery

Haven't seen any other reports of this so I guess it may just be me, but when the latest CM update came out on 6/19, I installed superSU and flashed the latest update of CM and since then I've had intermittent problems with google services eating the battery on my phone.

It'll last for 30 or 60 minutes then go away but during that time battery app shows google services using 60% of battery, and it is draining around 1% of the battery every other minute. The only app I downloaded since the update was Hulu and that had already been on my phone, I just reinstalled to see if casting would work.

Anyone have any insight?
