Q: iOS 10 photo face recognition not working with apple smart battery case on iPhone 6

This is a Bug,but I think if you agreed to share your device status  info to Apple ,they already know the problem

The battery pack does not count as connected to power.  It is an annoying usability problem, not exactly a bug. But report it anyway.

You can use this feedback form:                   iPhone      

The faces scan takes a very long time anyway,if the photos need downloading from iCloud Photo Library. My iPhone only finished 1000 photos to scan since I installed the iOS 10 upgrade day before yesterday.

i'm having a similar problem. It scanned most of the photos, but stalled. It has said to plug in and lock the phone to scan the remaining photos for two days. I thought maybe it had something to do with where I had it plugged in, so I used the charger I had it plugged into when it scanned the first batch and left it alone for an hour and the photo count had not changed. I've rebooted my phone twice and no difference.

The faces scan can only scan the photos stored locally. Is your library an iCloud Photo Library? Then it will need Wi-Fi as well to download the photos from iCloud. The progress is at a snail's pace. Every morning I'm finding a few additional person's thumbnails to name when I click the "Add Persons" button.

I'm having the same issue, but without a battery pack or something like that.

After upgrading to ios 10 my iPhone 6S began to scan my photos, which are stored local on the phone.

There are around 26000 photos on my iPhone and it finished scanning around 2500 of them, but now it is not continuing.

Only new photos are scaned immediately after i have taken them.

Until now i tried the following things, but nothing helped.

- connected to original iPhone Power Supply with WiFi diasbled

- connected to original iPhone Power Supply with WiFi enabled

- connected to original iPhone Power Supply in Flight Mode

- rebooted the device

kind regards

Thanks Léonie,

I reported it. It is confusing however since all other apps (including updating IOS) consider the battery pack as being connected to the power outlet.

After connecting directly to power charger it took about 2h to scrub through my 2800 pictures.

Works fine since. It did heat up the iPhone 6 quite seriously in doing so. I noticed the same heat build up when I connected it to the charger the next night but not since. There seem to be some pretty hefty processing going on after upgrading to IOS 10. (but that's another topic)

kr,

Xavier

I seem to have the same problem on my Mac and iPhone :/
