My question- is this normal?
My iPhone 8 charges fine while in motion. Maybe a bad connection that disconnects due to vibration? Check both ends of the cable, and make sure the phone connects securely, and your case isn’t interfering.
My money is on case interference
More info needed. Are you using USB cables or did you get a Qi Charger? If a Qi charger, which brand?
I use a USB cable. As this is not normal (not to charge while in motion) I'll investigate. Many thanks for your help.
I charge 4 phones while driving.
The iPhone must be unlocked and open to charge. If you plug it in without opening it, it won't charge.
Have you tried all 4 USB ports ?
Unless I’m wrong, the fronts are data ports, the first time you plug an iPhone in you have to allow connection on the phone. The rear ports are power only and will charge no matter what.
Just Plug it in and unlock your iphone to charge.
