My iPad Mini was running very slowly in the last few months. It took 2-3 times longer to start an app. Text showed up 1-2 seconds after I typed on a on-screen keyboard. I had only a few simple apps installed on the device. iOS and apps were all up-to-date.
I was about to throw in the towel… but I decided to give it a final try… I backed up the device and then reset it. To my surprise, it ran quite a bit faster. I repeated the process on another iPad and it also ran faster after reset.
It looks like some software configurations are causing iOS performance problem. The steps to fix them are:
1. Backup your device
2. Open Settings app
3. Select General page
4. Select Reset (at the bottom of the page)
5. Select Reset All Settings
6. Done
Hope this helps!
