iPhone Xs and Xs max charging issue effecting all phones

I am having a similar issue, although I have raise to wake enabled. My phone very randomly won’t recognize a charger, but if I unplug it and replug it, it works fine. Also yesterday I plugged it in and it wasn’t recognized until about 2 minutes later. This morning I had to touch my screen to get it to recognize the charger. This is all via the wall plug (not a PC USB) I have also used 2 different official cables and one 3rd party cable, also have used 2 different 5w bricks and the 12w brick, all apple brand. I have the same issue on all of the above accessories.

It is Not working how it should. I can simply hit my power button to turn off the screen and the cable is not recognized. Screen must be awake for it to charge. This is after a couple of seconds of the screen being off, not the new security feature they added to the port.

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.

Note some devices are, for whatever reason, not compatible with the Xs/Xs Max. In particular, the Belkin Valet and PowerHouse were not.

You may want to check with the manufacturers of your power packs to see if they have made any statements regarding compatibility.

Also make sure you have updated your phone to iOS 12.1.

Here's another useful link: If your iPhone, iPad, or iPod touch won't charge - Apple Support

Especially the section "if your device stopped charging at 80%"

Note also that charging slows considerably above 80% to prevent overcharging. It can take a couple of hours to go from 80% to 100%. So you might try charging it overnight and see if it is at 100% by morning. Overnight charging is a best practice, anyway. If you enable automatic backups in iCloud settings the phone will create a daily backup when the phone is connected to power and Wi-Fi, and the screen is locked.

You should report your concerns to Apple using either the feedback page or by contacting customer service.

Applying this information and expanding on it.

iPhones since the 5s can use more than the 1000 ma, so they will charge faster using a 12 watt power source. The 5s will use 1500 ma if available. The 7 and 8 will use 2000 ma. The X and later can also charge at 2000 ma, and also at a higher current and voltage using a USB-C power source. As you point out, the devices will only charge at the maximum rate until the stat of charge reaches 80%; it then slows to prevent overcharging and overheating, shutting off completely at 100%. So it is safe to leave it connected after it reaches full charge.

The XS has a 2700 ma-hr battery, and the Max a 3200 ma battery. So using the included 1 amp power source a Max should take about 3 hours to reach 80% taking into consideration that charging is never 100% efficient, and probably another hour or two before reaching 100%. Using a 12 watt iPad power source will halve the time to reach 80%.

These values assume that the phone is not being used while charging; if it is the charge time will be longer.

Sorry if I’m not in the correct forum. But I’m in the uk and had this problem from getting the phone out of the box.

If I use the wireless charging never have an issue. However if I use chargers on occasions it charges on occasion it doesn’t.

I have contacted Apple on the first day already and spoke to a technician who had never heard the fault. But did say I can have a replacement but none in stock and no idea when I’d get a replacement.

However I don’t believe it’s hardware but more software.

I’ve plugged in lightning headphones and even the work with out unlocking the phone each time.

What also puzzles me. I paid £100 for a Belkin Valet to only find that doesn’t work with XSMax, XR, XS.

So I’m not impressed at that. So my question is. What has apple done to the charging port, what has apple done to the Belkin to stop that from working as a apple 5W charger works fine and the bekin is more powerful.

Has apple altered something on the port it self to make it less crackable. Would apple also like to pay me £100 for a product I can’t use but it has a compatible MFI port.

All my power banks work fine so why not Belkin and why not when it’s a sleep. Shouldn’t the phone be able to know what’s a charger and what isn’t. Or is the phone looking at something in iOS 12 or is there a design flaw ?

Well, the charging bug is still with us (as of 10/19/2018), although it may be more subtle now.

I have an XS Max, running iOS 12.0.1, and last night the phone did not charge at all. Coincidentally this morning I had to enter my passcode to unlock the phone, because the Face ID had timed out (you know, one has to enter the passcode after continuously using Face ID for 156 hours).

I suspect that the phone did not charge because of the Face ID timeout.

Since updating to iOS 12.1 my phone stops charging both wirelessly and with the standard lightning cable at 81% but the most if any it’ll go to is 87% and no further. Contacted support and all they could tell me was to do a factory reset and see if that fixes the issue.

Does Battery Health show any issues?

some issue here with my XS Max - friend of mine does also have the XS Max but his phone does not have any problems...

there is another thread already:

iPhone XS Max lightning port charging issue

The situation you describe may be as designed:

Lightning-Based Charging May Not Work If Your Device Has Been Idle over an Hour or You Did Not Use a Cable Within the past Three Days

Its most likely that you have dirt in your Lightning port. Get a bright light and a toothpick and clean it out.

The Belkin valet issue is being addressed by Belkin; they explicitly state the Valet is incompatible with the new phones but they are making efforts to give credits to existing owners towards purchase of a new compatible Valet. The offers differ by person, so contact them and find out what they are willing to do for you.

Read the link I posted immediately above your post to learn more about why you may need to change settings to get charging via a Lightning cord to work the way you are used to.
