Right, a normal app (from the store) is not allowed to block suspend at all.

The only thing that is currently waking up the phone (from our
userspace) is the push-client, and that gets used once you set up an
account (it wakes up the device at every 5 minutes).

I'm trying to profile it here to see what is going on, but I'm getting
~4,3% per hour (with radio enabled, not using the phone).
