Microsoft Clarifies Windows Phone 7 Push Notification Limit
A few Windows Phone 7 users may have started to panic earlier this week when word got out that the operating system has a hard limit on the number of of apps that can receive push notifications, capped relatively low at 15. Microsoft has now responded to user concerns, explaining in detail exactly how the limitation plays out and what to do about it if it begins to affect you.
The key bit to remember is that the push limit is not going to keep you from installing new apps, nor will it force you to remove all your live tiles to free up space. Anything that comes with the phone will not count towards the limit, so you’re not helping anything by shutting down Outlook. Only third-party programs you install will count against the 15.
You can install as many apps capable of receiving push updates as you’d like, so long as they let you choose whether or not push is enabled; only 15 can be using the system at any one time. When you go over the limit, developers will likely have their apps alert you that you’ll need to disable push for another app before turning it on for the new one.
Microsoft defended the limit by saying it’s in place to conserve phone resources, and that it decided on 15 only after studying plenty of user behavior. If it turns out that there’s a real demand for letting a greater number of apps get push updates, Microsoft said it’s possible for the number to later be increased. A change definitely isn’t in store for the next WP7 update, but it’s something we could see later down the road if the limit becomes a real problem.
