iPhones not charging with Apple cables after iOS 26.3

Hello everyone,

I’m experiencing a strange charging issue after updating to iOS 26.3 and would like to know if anyone else has encountered something similar.

Devices:

• iPhone 15 - iOS 26.3
• iPhone 16 Pro - iOS 26.3
• AirPods Pro (2nd generation, USB-C)
• Original Apple USB-C power adapter
• Two original Apple USB-C cables (from two different iPhones)

Description of the issue:

After updating to iOS 26.3, both iPhones started having problems charging with the original Apple USB-C cables.

Here is the behavior:

1. When the phone is powered on, it does not charge with the original Apple cable.
2. The Apple cable only works:

• In one specific orientation (if I flip the USB-C connector, it does not charge).
• And only if the phone is powered off.

1. If I connect the charger while the phone is turned off:

• The phone turns on automatically and starts charging.
• If I then disconnect it, I cannot charge it again using the original cable unless I reboot the phone.

1. I tested two different original Apple cables - same behavior.
2. If I use a third-party USB-C cable:

• Both iPhones charge normally.
• Charging works in both connector orientations.
• No need to reboot.

1. AirPods Pro 2 charge normally with third-party cables as well.

This makes me think the issue could be software-related, possibly introduced in iOS 26.3, rather than a hardware defect - especially since:

• The problem appears on two different iPhones.
• Diagnostics performed by Apple Support showed no hardware issues.
• The issue started after the update.

Apple Support suggested visiting an official store, but diagnostics didn’t detect any hardware failure.

I could downgrade to iOS 26.2 to test whether this is firmware-related (possibly something affecting the USB-C power controller), but I prefer not to risk losing data.

Has anyone experienced a similar issue after updating to iOS 26.3?

Any suggestions or insights would be greatly appreciated.

Thank you.
