iPad Pro 9.7 iPhone 7 I installed iOS 10 6 days ago (release day mid-day) on my iPad Pro. iPhone 7 was setup around noon on Friday Both devices stayed plugged in all weekend, my iPad Pro was plugged in all day during work hours. I have 86,501 photos in iCloud Photos. Photos & Videos takes up 525 gigabytes of data on iCloud. It's Monday at 4:30PM and both devices are still struggling to scan the library: I intentionally left both devices plugged in and locked for 3 straight days and they're still not done. This would be a full week for the iPad working 16 hours a day and it still hasn't finished scanning. I'll also add that on day one of scanning, I had to switch to the wall-plug for both devices because they would actually lose battery life despite being plugged in to my USB 3.0 powered outlet. Also, both devices are noticeably hot every time I pick them up to check the status w/o a case. My devices are plugged in at my desk, in the car and at night while I'm sleeping. I really thought they'd be done by now. I don't use them during the day since I have a computer. Is this normal?
