Windows Phone 7 has a 15 app Push Notification limit

Only 15 apps can register for Push Notifications at one time.

Push notifications is a feature widely touted by Microsoft as a feature that  both encourages glance and go and reduced the need for multi-tasking in the OS.  It is certainly a feature we really appreciate in applications when available.

It now appears, according to Clarity Consulting, that Windows Phone 7 has a hard limit to how many apps can take advantage of this feature on one device.  After the 15th app that registers, the 16th will hit a “InvalidOperationException(Channel quota exceeded)” error, and will not be able to notifications.

The reason for this limit is not clear, but we can certainly quite easily see how we could have more than 15 apps using push notifications, so we really hope Microsoft does not intend to keep this limit in place.

Of course we can see a place for limiting how many pop-ups and toast notifications will appear on a handset, to manage the user experience, and this may have been Microsoft’s intent. There is however a further criticism that Microsoft does not provide a tool in the OS to manage applications that are registered for notifications, making it a guessing game if users run into this issue.

Do our readers think Microsoft is right in limiting how many applications can do possibly annoying notifications (which can be toasts or tile updates of course) or has Microsoft sold a feature which the OS at present just can not deliver? Let us know below.
