TIL. How does Signal sends push notifications without GCM?
- MayeulC 5y agoJust like how google services handle push notifications on your phone: a persistent connection. Without GCM though, every app needs to maintain a separate connection, which drains more battery. That's why we need more alternatives to GCM, like UnifiedPush.
