In my experience it's not bad enough to worry about. I have: - Signal - Whatsapp - Etesync - Conversations.im - Syncthing all whitelisted from battery optimisation, and I've not noticed any huge drain (I expected it to be unusable and have to go back to google play services or micro-g).

Signal uses gcm to push to the phone thus waking it so it can download any messages. Not sure about the others though.

  If you don't have Google Play Services, it doesn't use GCM.
