iPhone 15 pro max reverse charging issue

Hi Robin bro, I am using iphone 15 pro max. I have charged my phone using powerbank while going to sleep. It was on 6%. And when I went to sleep it was around 46% still charging.
When I woke up in the morning found my iPhone drained to 1%. Guess this is because of the reverse charging. I checked the battery stats it shows Accessory. This is a serious issue with Apple I think , do we have option to turn off reverse charging. Or can we report this to Apple

hi bro, this issue was there with older iOS version. I remember apple fixing this issue sometime ago. Whats your current iOS version?

Hi bro ,
I am on latest stable version 17.6.1 . I spoke to Apple customer care via chat . They are saying it’s an issue with powerbank nu. But I do not believe it. I am using Oneplus powerbank which is PD certified. Cable is Apple provided one in the box. iPhone I think detects this powerbank as an accessory I guess.

with initial iOS 17 release there was a bug causing such issue bro. they fixed it around 17.1 update itself. wondering how come you are experiencing this issue even with 17.6.1 update.

once perform “Settings - general - reset - reset all settings” bro. then same powerbank 1 week use pannunga. 20% varumbothu phone charge pannunga, powerbank or power adapter as per your choice.

and see if you are seeing any difference bro.

else we can try iOS Restore once and see if that helps or not bro.

Thanks a lot brother
