    The CPU on my iPhone 6 has been solidly 100% since the update for about ten minutes now.

    The same thing happened a few weeks ago when I upgraded my iPad. It eventually settled down after about half an hour.

    What the heck is the system DOING? Is there any way to find out? The System Status app is great at telling us the CPU is being used, but doesn't tell us on what.
