Yesterday I updated my iPhone to 11.4.1. I plugged it into my Belkin dock as usual in the evening. In the morning it was only at 30% charge so I thought I hadn’t docked it correctly. However this evening when I docked it I noticed the message “Unlock iPhone to use accessory” and the phone was not charging. It only charged after I unlocked it. This unannounced and pointless change is a serious personal safety issue as people will assume their phone is charged for the day.

Interestingly the Apple Discussions AI would not let me post this advice on their (its?) website

That’s strange. Both of my iPhones and iPads charge fine with non-Apple chargers. A better title for this thread would specify “Belkin dock” instead of non-Apple accessories.

This is a new security feature in iOS 11.4.1 to deter hackers from using hardwares to hack into your phone. Just unlock when you connect the phone next time.

If you still want your phone to work like before then flip that toggle.

Sounds like a poorly-designed Belkin product. I'm not quite surprised.

Your dock is asking for data access to iPhone when it doesn't need to for charging only.

That's strange, I have 2 Anker cables and a dollar store cable that all charge my iP7 just fine.

Just found this link via another forum:

Using USB accessories with iOS 11.4.1 and later
You might need to unlock your passcode-protected iPhone, iPad, or iPod touch to connect it to a Mac, PC, or a USB accessory.

I did try searching the Apple Support webpages for this advice without success. So my apologies to Apple. I have now switched on USB Accessories support (but will take care using unknown accessories as usual).

The odd thing is that Belkin Dock is just supposed to be a charging station - it has no other function - and it was apparently Apple-certified when I bought it many years ago. I have found it very handy for video conferencing since the iPhone is upright and still charging.
