This app basically keep alive the push connection on your phone. It avoids the tcp connection timeout that can occurs on some wifi routers or on some mobile carriers.
● How does PNF solve this problem?
Every x minutes the app invokes an android activity that will send an heartbeat network packet on the push connection. Sending an heartbeat every 5 minutes should be enough to always keep the connection alive and all your push notifications will be instantly.
● How do I restore the default heartbeat interval value?
Android heartbeats values are not modified by this app, just uninstall this app.
Android heartbeats values are not modified by this app, just uninstall this app.
The battery should not be much impacted over a day.
Q: Does this app drain battery in background? Does lowering the heartbeat interval too much cause more battery drain?A: It should have not a big impact on the battery during your daily use. I recommend hearbeat set to 5 minutes, it should be enough to make you receive instantly notifications.
Q: What does mean "set the heartbeat to x minutes" ?
A: It means only that android will send a network packet over the push connection every x minutes instead of the default 15/28 minutes to keep alive that connection. It does NOT mean that you receive push notification every x minutes. Notifications are instantly if the push connection is alive.
Q: Why Whatsapp messages are still delayed sometimes?
A: Whatsapp, and some others apps, don't completely rely on google push service (GCM). Those apps start their own connection when you open the application, and the messages come through this connection. The heartbeat is sent by android only on the push connection on the port 5228, and so it only keep-alive that particular connection. Blame those apps that doesn't have a keep-alive mechanism for their connection or that doesn't use full push messaging.
A workaround for whatsapp is to swipe it away from the recent apps when your finished a chat session. In this way it's connection is dropped and you will be notified of new messages through google push notifications.
