I’ve seen the reports of the XS and XS Max charging issue where they won’t charge if they’re asleep and you have to raise to wake them first. I’m not experiencing that issue however I am experiencing a more bizarre issue in that out of the two mobile power packs I have (1) and older RAVPower 16,750mAh pack with a 2.1 and 2.4A USB A ports and a newer (2) TUMI 6,000mAh pack with a built in lightning connector cable and an extra USB A port.
The RAVPower works just fine when connected by USB A to Lightning cable to my iPhone XS regardless of whether its awake, unlocked or otherwise. The TUMI however (and this seemed to start happening after the most recent 12.1 update I think) is that when it’s connected to the built in lightning cable doesn’t register it at all. The TUMI starts to flash briefly indicating it’s charging the device, but the iPhone doens’t show it’s charging and even after leaving it connected for hours doesn’t charge. However, if I connect my wife’s iPad Pro 9.7 or her iPhone 7 to that same built in cable, it starts charging those devices right away. Furthermore, if I use a separate cable and the USB A port on the pack and connect it to my iPhone XS it starts charging so I know it’s not an issue with the power pack or the cable but given it is only the built in cable and my iPhone XS that wont work together I can’t figure out why this would be the case.
As far as I know the built in cable is at minimum a 2.1A 5V current so it shouldn’t have any issue charging the iPhone XS. Plus the fact that it charges an iPad Pro 9.7 or the iPhone 7 means it’s obviously working.
I’ve tried resetting my iPhone XS, turning off the USB security in settings, everything I could think of but nothing fixes the problem. Furthermore, my iPhone XS seems to work with the RAVPower or any other third party charger/cable I have laying around.
Any ideas what could be causing such an isolated issue with this one particular power pack?
Note: I tried to post this as separate question but this community forum wont let me post saying ”I’m not allowed to create or post content” for some reason which is just another frustrating experience. It’s not like I’ve posted anything innapropriate or whatever that would have got me banned. So I was able to post it here as a reply.
