title: Should i use push notifications for all new instant messages
body: <p>I am using a custom php webserver for an im program to send push messages, for now i can send push notifications to mobile phone but i am not sure about how to use it properly.</p>
  
  <p>By this i mean should i send all messages as push notifications, is it possible to do that? Is there any limitations about push notification's size? Or should i start a timer to check new messages after first notification and finish the timer when the activity is closed?
  So what would be the most proper way to get instant messages from the server?</p>
