GrapheneOS doesn't have a centralized push notification service integrated into the OS. If you install Signal in a profile where you haven't installed sandboxed Google Play, it will only use Signal's own servers for push.
Signal's push implementation isn't power efficient and will drain a lot more power than Google's Firebase Cloud Messaging. However, there's a fork of Signal called Molly supporting using an arbitrary push provider with efficient implementations available.
