We’ve asked what happened to the Push Notification Service that iPhone Software VP, Scott Forstall first announced back at WWDC 2008. We’ve even wondered if Apple had changed their mind and gone with a true background multi-tasking approach. Or whether they’d simply scrapped the idea entirely?
Turns out Push Notification took a little longer to polish up than Apple anticipated, in addition to developers requesting features above and beyond what Apple initially expected (though, in all “truthiness”, we didn’t see anything new above the surface yet ourselves).
Apple claims to have tested Windows Mobile, Android, and other devices running background IM, and that battery drain was 80% compared with 20% for Push Notification. We’re not buying that yet, but we are happy Apple is taking their time with this. Better a rock-solid implementation than anything approaching MobileMe’s disastrous launch.
So what is Push Notification and how does it work? Read on after the break!
