iphoneX is not being charged in car via USB hub splitter

USB hubs may have limited power available, and may not be accepted by all devices as valid charging supplies. Connect your phone direct to the car’s USB port using a genuine Apple cable, or give the phone its own dedicated charging power adapter, like https://www.apple.com/shop/product/HLRQ2ZM/A/belkin-usb-c-car-charger?fnode=97&fs=f%3Dadapter-charger%26fh%3D458e%252B45b0%252B45d4

It can happen, using USB-Hubs. I would try a dedicated car charging adapter:

You have already proved the failure to charge is due to the USB hub(s), and Apple support document https://support.apple.com/en-us/HT201569 suggests a USB hub which can accept external power might work. I am not aware of any USB hubs which are designed to take external power from a car so this would probably be an unsupported and uncertified configuration using a third party 12v adapter to power your hub.

In my opinion there is no practical way to resolve the problem within an existing phone or software. If your iPhone requires more power than your USB hub can provide or it does not work with an uncertified third party charging configuration, that is not something Apple can resolve.

It appears Apple may be moving toward USB-C to replace Lightning so we will have to wait and see what appears in the next generations of iPhone, but it seems unlikely they will see a commercial reason to develop a (12v) car-powered hub for legacy USB applications. However, you can submit wishlist entries at https://www.apple.com/feedback/

I would still go with a standalone charger, at least for testing to prove the point and also as a backup if other methods leave you with a depleted battery while on the road.

Why does this hit the latest models? Maybe because they are capable of drawing more power while charging, so they are more likely to notice a low powered charging supply. I may be wrong... is it iPhone X and later can fast charge using Apple’s higher power USB-C adapters? (I know my XS can do it). This might have required some logic changes to detect different charger capability and the USB hub is confusing the phone.

Grazie Branta,

but when it happens (writing the same things, not adding anything interesting / new), I feel like a parrot :-(, and I need to apologize, as a matter of respect for my colleagues.

Keep well.

Giulio

Whoops... sorry, Branta, didn't see your reply in time :-(

Have a nice Sunday.

Buonasera Giulio. I was only 2 minutes ahead, no problem. Remarkably we both picked the same car adapter, which is the one I keep in the car as emergency reserve.
