Currently firing every minute is a silent notification to update the app, than a fetch in-app takes about 2 seconds.

I can't find anything on a rate limit but it's for the future of this app very important to find out what is allowed before Apple will rate limit it.

Currently it's one minute, what if we set it to 30 seconds for example?

Will that still be allowed?

For now 1440 pushes(every minute) are sent to a user per day to keep his app up to date but we want to know if this keeps working on a larger user scale.

There are some very important features concerning the rate limit:

1. You (the developer) have absolutely no control over the rate limit.

2. The rate limitation is undocumented to allow Apple the freedom of changing the behavior as often as they want.

3. The rate limit is going to change under various circumstances. One of the threatened or promised behaviors concerning silent notifications is an expontential limiting feature--the more often your application is requested to be launched, the less often the system will be willing to launch your application.

So I have to ask whether you've actually tried sending 1440 push notifications to your application without the application running in debugging mode. My expectation is that your app would not actually receive many of those notifications. Especially if you left the device to idle for about an hour or two with your application not active.
