After iOS 17 iPhone 11 is not charging

12/14/23

We always have Background App Refresh off.

Turned off Optimum Charging.

The problem was four-fold:

1-The rubber on the Otter Box was slightly impinging on the lighting cord connection (easy to correct)

2-17.1.2 IOS Update

3-Optimum Charging off

*(after the above 3, phone charged somewhat better but not consistent, would actually show it was charging but lose battery %)

4- New Apple 20W charger was intermittent, I figured it out late night when I noticed the phone lighting up-on and off (cord verified as good)

After receiving warranty charger, pone now charges as expected.

Restored the "Optimum Charging" feature.

In my case I can't say for certain if the IOS was the culprit or a combination of the above damaging the charger.

HTH someone.

Hey, I posted a solution to this problem early in this thread. I can’t believe they don’t highlight it or something. It’s worked for a bunch of people. Goto settings-battery-battery health and charging- turn on then off both optimized battery charging and clean energy charging. This worked for me and others. You can double check my earlier post to make sure this is what I suggested earlier. Hope it helps.

I just updated my iphone12 to ios 17.7. Was working perfectly with a cable charger before, then as soon as it booted after the updated, didn't recognize the charging cable.

Tried all the advice on here, with no joy. But the thing that got it working for me .....

Settings - Battery - Turn on Low Power mode. As soon as I did this it recognised the charger.

I was able to then turn off low power mode, and it continued to recognise the charger cable.

The only other thing I did was charge it to 100% on a wireless charger before trying the low power switch.

Update: after speaking to Apple on the phone they told me to turn off optimized charging *AND* background app refresh and this has seemed to do the trick for me

update on my iPhone 11, i tried another charger and it seemed to have worked just fine, the older one charged really slow

So I got help with apple support just power off your phone all the way then power it back on and it should work it helped with my iPhone 11

THIS HELPED ME AS WELL. I had to turn opt. battery charging off, switch off the phone, switch it back on. Then go to the settings menu again, turn on and then very very fast turn back off the opt. battery charging option.

It started charging normally after!

It's not a cord, plug, or any other issue, it is an update issue. This happened to my mom, my stepdad, my son and me. We all rushed out and bought tons of money worth of brand new APPLE BRANDED cords, and plugs and nothing is working. It is happening on all of our devices. My son is using a mini ipad 5th gen, i am using an iphone 12, my mom is using an iphone 12 mini and an iphone 11, and my stepdad is using iphone se the newest generation one. We are all fully updated on ios. This issue needs to be addressed in more than just a robotic copy paste response.

After the latest IOS update my iPhone would not charge, so after going into settings on my phone I found that the charger needs to be plugged into a wall outlet! I had been using a surge protector power strip for years with no problems, after I plugged the charger into the wall it started to charge but Very Painfully Slow. Phone also charges on a wireless charger.

I've had the same thing with my XR since I "upgraded" to IOS 17.3.0. I can see the battery display lose charge while plugged in and no active use. Took into a Genius Bar appointment and their recommendation was to factory reset and start over... or upgrade to a new phone. I'm not prepared to do that now. The thing that seems to be working for me at this time is to

• turn on Low Battery Mode (I've already disabled background app refreshes),
• close off all open apps,
• turn off the phone by pressing the volume up and side button,
• swipe right to turn off phone,
• wait for the screen to go completely dark (while closing down, the screen is still dimly lit),
• then plug in the charger.

Once you've done these, the phone will charge on a cable as per normal... and go to 100%.

Apple, you need to do better. There's lots of people here on this forum and lots of online chatter outside of this community with people facing this. It needs to be fixed.

i tried a hard reset this morning, restoring from icloud and according to other threads bugs are not backed up and a fresh copy of the software gets installed

I had the same issue and then I connected it to my laptop and let it access my iPhone data. It ensured me that charging port has no issue. Same time it started charging 🤔 but slowly

👉🏼WORKS AFTER REBOOT😍

Hey there maharajg,

Thanks for reaching out to Apple Support Communities. We'll be happy to help with your iPhone. If you're running into charging issues that continue when using another charger, test a different cable, adapter, outlet or port on your computer. If the issue continues, ensure iOS is up to date.

Take care.
