And yes, I have my cal synced through the exact same z-push server, thanks to owncloud - but that isn't the point of the thread...
Have you tried IMAP IDLE on an iPhone or blackberry on 3G? Obviously not due to your comments.... it is *far* from being a "poor man's push" service...
If you think Blackberry holds the patent on push email, give this a read:
http://en.wikipedia.org/wiki/Push_email
then get back to me, because what is written in the RIM section is *exactly* what z-phone does. |
And you get your information from wikipedia ? Come on... Every car has an engine and 4 wheels, doesn't mean they are the same. Everyone can claim they do push, but nobody does push like RIM. They are the real deal. Everyone else has weaker methods. That's why a Blackberry's battery can last for days and not die.
Here it is explained in more detail than that Wikipedia article says. They don't even define "push" properly.

The BES monitors the email server, and when it sees new email for a BlackBerry user, it retrieves (pulls) a copy and then pushes it to the BlackBerry handheld device over the wireless network.

With Activesync the device maintains a connection to the Exchange/Z-push server and gets notified when a new mail arrives.
With BES, the BES server polls the inbox, forwards the message to RIM's Mail Hub in Canada/US which then contacts your carrier which in turn truly pushes the message from the tower to the device.
Activesync "push" is just a marketing gimmick.
Second of all, you are doing something wrong or seeing some skewed results somehow. There is no logical reason for an application that connects one time every 20 minutes to check mail, to take up more power than an application that maintains a connection open all the time. In fact, on my S3 I keep it on check every 5 minutes because "push" really kills my battery. And yes, I run z-push as well with Calendar, Contacts & Tasks synced up.
