Anyone else experiencing more than almost 10 minutes after turning on their devices? It appears to take this long on my iPad 4 (4th generation model) and my iPhone 5. =T It has never taken this long and I had been updating with a developer account the last few months. I've never had it run this slow where I'm afraid sometimes the device won't even turn on.
iPhone and iPad both taking longer times to load since iOS update
on my iphone 6 im experiencing around 5 min. waits to start and once it does it will freeze on a random app and then ill have to go through the whole restart process again.
I've noticed the same thing, lag is incredibly long, almost wished I didn't update...
Try to restore without backup... These problems appears sometimes when inherited data from previous versions are incompatible and/or invalid. Probably, newer versions will fix it doing some data conversion.
