Charging issues with new IOS 16.1.1

I can confirm that for my issue, it was not the old, weak battery - it was a failing charging cable. With the new cable I received today, my charging issues are fully resolved. Thank you all for your advice!

jliza ~ The long process of applying an iOS update to an old iPhone XS model with an unnoticed weak, original battery can be the proverbial "straw that broke the camel's back." Also, your 84% max capacity can be misleading as it's only an algorithmic estimate of a dynamic chemical process. And others here have reported a battery "significantly degraded" alert at 89% max capacity!

...So, you can wait for suggestions from other users here, but I would have that aging, likely weak battery replaced:

Short answer of what worked for me: turn off Clean Energy Charging option under Battery Health & Charging (in battery settings).

Long winded answer below:

I have an iPhone 12 and recently updated to iOS 16.1.1 too and noticed when I placed my phone on my MagSafe Charger it wouldn’t charge. I did the usual checks - cable & charging block but nothing worked until I turned off Clean Energy Charging under Battery Health & Charging. Only then was I able to start charging. Reading up on it, sounds like the iPhone will selectively charge based on when lower carbon emissions electricity is available. I’m all for reducing carbon emissions but not at the expense of preventing charging my phone when I need it. I’m not sure if this was the root cause of me not charging my phone but after disabling this option, it now charges. Not sure if there’s a bug if you don’t allow all the required options to be enabled but this should not be on by default. Hope this helps others.

Liza ~ Have you tried this as previously suggested by ImAnEnjinear?...

Hey there jlizafromma,

Thanks for reaching out to the Apple Support Communities. To get started, you've done some great troubleshooting steps on your own already. To help isolate the issue further, we'd recommend going through any step you haven't already tried in this link here: If your iPhone or iPod touch won't charge - Apple Support

If your device charges slowly or won’t charge

Follow these steps and try again after each:

1. Check your charging cable and USB adapter for signs of damage, like breakage or bent prongs. Don't use damaged accessories.

2. Use a wall power outlet and check for firm connections between your charging cable, USB wall adapter, and wall outlet or AC power cable, or try a different outlet. 

3. Remove any debris from the charging port on the bottom of your device, then firmly plug your charging cable into your device. If the charging port is damaged, your device probably needs service.

4. Let your device charge for a half hour.

5. If your device is still unresponsive, force restart your device: 

- iPhone 8 or later and iPhone SE (2nd generation): Press and quickly release the volume up button. Press and quickly release the volume down button. Press and hold the side button until the Apple logo appears.

- iPhone 7, iPhone 7 Plus, and iPod touch (7th generation): Press and hold both the side (or top) button and the volume down button until the Apple logo appears. 

- iPhone 6s or earlier, iPhone SE (1st generation), and iPod touch (6th generation) or earlier: Press and hold both the side (or top) button and the Home button until the Apple logo appears.

6. Let your device charge for another half hour.

7. If your device still won't power on or charge, take your device, charging cable, and charging adapter to an Apple Store or Apple Authorized Service Provider for evaluation. You can also contact Apple Support.

If still having issues after going through the steps above, have you noticed if your iPhone feels warm to the touch while charging? We ask because, if the interior temperature of your device exceeds the normal operating range, it is possible that charging may stop or slow.

You can find this and more details at this link here: If your iPhone, iPad, or iPod touch gets too hot or too cold - Apple Support

Keep us updated with the results.

Take care!

Hi Liza, no worries we’re on the west coast so Thanksgiving dinner is hours away.

The next thing to look at is trying new cables (I’d recommend using a Apple MFi certified cable to eliminate that as a potential cause). Other than that, it may require more diagnosis with a tech. Sorry I couldn’t provide more help, good luck!

Before we conclude this is happening because of the battery, note that, as an example, my phone was at 1% charge; I inserted the charging cable, came back after 4 hours and it was still at 1%. I removed the cable, reinserted, and it charged up to 17%."

BlueFil ~ Your iPhone XS is displaying the classic symptoms of a weak, years-old original battery in need of replacement:

• Less than 80% maximum capacity

• Inconsistent ability to charge

• The long process of applying an iOS update to an old iPhone with a weak battery was the proverbial "straw that broke the camel's back."

...So have the weak, original battery replaced and all will be well:

Bluefil,

While you consider getting a new battery replacement, have you tried a new charging cable? The weak point of a cable is at the cable to connector interface from connecting/disconnecting it from your phone. The connector wire strands are soldered to pads on the corresponding connector (internal to the cable/connector) and that is a weak point that could cause intermittent contact. These are fine gauge wires that easily become dislodged or break from the pads.

Hi Liza, the charging adapter block bought in the US should work fine in Europe and other parts of the world (there’s fine print on the block itself where it states ratings for Input (going into block from socket) & Output (going to device) for both current and voltage. The input should read 100-240V or similar, which is the AC voltage range the block can use (seeing this range means it can be used across different regions). I personally prefer Anker blocks/adapters but it’s personal preference.

Since your Mac charges fine using the same electrical socket, have you tried charging your iPhone using a cable plugged into your laptop (using Mac as your power source)? Another option would be to get a rechargeable battery brick (back up power) and try charging your phone using that with a USB cable.

Lastly, trying to troubleshoot the electrical wiring in an old building would be beyond the scope of your current issue unless you know how to use a digital multi-meter and are familiar with electrical wiring. Also, the power coming out of a socket in an older building in Europe (depending on where in the EU) may not be as “pure/clean” compared to the US but that’s a separate issue altogether.

Hope your Holidays are going well minus this charging issue.

I had this exact issue - iOS 16.1.1, iPhone 12, mag safe stopped charging after about 30 seconds. Changed battery power settings like above, but then the problem continued. I am attempting to upgrade to iOS 16.1.2 right now. Also, if I charge from the USB-C/thunderbolt jack on the phone it does charge successfully. I tried rebooting the phone and no luck. As of right now I cannot charge from my iPhone 12 magsafe charger. This problem started only about 2 days ago for me (~12/2/22) out of the blue.

BlueFil ~ What's the Maximum Capacity % here?...
