iPhone XS doesn't charge after update to iOS 14.

(3.) Continuation to (FInal)

https://discussions.apple.com/thread/251804766?answerId=253562081022#253562081022

Last time I wrote I will test my iPhone with the sim card again. I tested that for about 48 hours. I played with my iPhone XS games, looked Videos, surfed in Internet and read eMails and WhatsApp. All the time Bluetooth and WiFi were switched on. Also I used my AirPods Pro and other headphones. And again, I didn't met any issues with my battery or charging.

(3.) Final summary of my tests:

My problem:

Immediately after updating my iPhone XS to iOS 14, I got the following battery issues:

• restart after few hours
• wrong battery charge level (0 - 1%)
• not able to charge with any charger anymore
• battery went empty and the iPhone went off
• not able to perform the Hard-Reset, Factory-Reset, DFU Mode or to read out the device for Apple diagnostics.

My tests and tries:

• Charge it with other charger:

I tried to charge it with other chargers, including a strong one (Anker 45W Power Delivery) - > Unsuccessful:

While putting the charger cable, the device recognizes it and the big empty battery symbol appears in the middle of the display. But also after 12 hours, the iPhone was dead. I was still not able to switch it on.

• Replacement of the battery:

I replaced the battery with other original Apple battery -> Unsuccessful:

I was able to turn on the iPhone. The problem was gone for a few hours. But then my iPhone suddenly restarted and the battery icon in the top right corner showed empty. Before restarting it was like something over the 50% of charging level.

• Factory Reset:

I backuped the iPhone, performed a factory reset (erased all data) and restored all data again -> Unsuccessful:

After these steps, my iPhone did the restart again and showed 0% battery symbol again. But I was still able to turn it on (maybe because of the new battery or "better" data on my iPhone after restored data). Perhaps you will be successful at this point, but it didn't work for me.

• Removed the sim card / turned the mobile connection off:

I removed the sim card and tested it without mobile connection (Wifi for Internet only) -> Successfull - No issues anymore

• Tested with the sim card again / mobile connection on (full load):

I installed the sim card again and tested it with full load again -> Successfull - No issues anymore

Possible reasons for this success after all these troubles:

Time-dependent success:

This high current consumption of the iPhone, due to the optimization work after updating my iPhone to iOS 14 is finished after few while i was testing my device. I started to test and analyze this issue since 25th of September and I did it until 1th of October. My first success was round about at 28th of September. The well-known optimization processes of iOS 14, which are usually carried out to improve the work of the operating system after installation of new os, is probably gone after 4-5 days (depends on how much data and apps you have installed).

Load-dependent (deactivated mobile module (without sim-card):

To high current consumption of the iPhone because of the optimization work of iOS or any other iOS 14 bugs are still there, but the overall power consumption is less due to the deactivated mobile connection module (sim card was pulled out). The battery was able to manage this high current needed for optimization work.

My conclusion and advices for people who have similar probles

After installation of the new OS, like iOS 14, the OS performs a lot of optimization work. This optimization work initiates a very high power consumption from the battery.

This high power consumption causes troubles like:

• iPhone gets hot
• the battery go empty to fast
• the battery live (Capacity in %) go to fast down ( minus 2-3% after update to new OS)
• the battery symbol shows wrong battery level (weak battery)
• the iPhone wan't be charged over x percent (e.g. 10-20%)
• the iPhone wan't be charged at all (weak battery)
• the iPhone is dead after short time after updating to new iOS, it can't be charged, it can't be switched on or read by Apple (weak battery)

My Solution for these issue:

1. Please try a different charger first. Better a stronger one, like the Mac-Book charger. Do not forget to clean the lightning onnector of your iPhone. In cases where the iPhone cannot be charged and therefore cannot be switched on, the battery must be replaced. Your iPhone is not dead. Due to the high power consumption of your battery, this battery is either damaged or cannot be charged via the iPhone charging system.
2. If you can turn on your iPhone, e.g. after replacing the battery, or if you have any of the problems listed above, e.g. if the iPhone doesn't charge above 10% -20% but your iPhone still works, then you will have to wait for your iPhone to finish all the necessary optimization work. It will take about 3-5 days. The exact duration depends on the number of your apps and media. To make this process easier for your device, please turn the Bluetooth, Wifi and mobile connections off. You can switch your iPhone to "Fly Mode", but don't switch it off completely. Also connect the charger to your iPhone. You can't use your iPhone regularly in this time. After the optimization work is finished, you will never have these problems again and can use your iPhone normally.

My Verdict:

These issues are caused by Apples new Update. In my opinion, all cases need to be covered by Apple, whether or not a warranty is still available. At least, the batteries will need to be replaced for free if the iPhone cannot be turned on.

However, this is my opinion and my analysis of the subject. Without guarantee of correctness!

Than you! I'm done! :-)

Hi, Andy!

Yes, my iPhone is still working.

It seems like your iPhone has exactly the same behavior like my iPhone.

After changing the battery (original from eBay), factory reset and restoring of all my data and apps the problem was still there. But after some days without the sim card inserted, the problem was gone.

I don’t know exactly what was the problem. But what I know, the people write about optimization procedure in iOS 14. I think it was finished and now it is good!

I use my iPhone a lot. I tested it also with games, like need for speed and asphalt.

I didn‘t test it with my fast charger from Anker. Maybe I should do that for completion of my tests.

But for now, my iPhone is good!

My first battery is either defective or my iPhone can‘t charge it because of very low voltage level.

Factory Reset - will erase all your data: https://support.apple.com/en-us/HT201274

Make sure you have backup from your data first.

What do you mean with "I had the exact same problem"? Did you get this issue also immediately after updating to iOS 14?

Thank you for your advice, but I think we have to differ between "my charger is defect" and "My device won't charge and the battery is spinning".

The first one is simple. You just have to try another charger before you write your complaints here in the community.

The second one is a difficult case. If you already checked your lightning port and a lot of different chargers and you are absolutely sure that this issue appears after updating to iOS 14.

So, please don't irritate the people here and helpe with voting to make it visible for developers and Apple management.

I went to Apple, they told me, this is a hardware problem. They can do nothing with it. I didn't believe them and replaced the battery by myself. Because I was not able to charge my old battery. After that I was able to do a factory reset and charge the new battery from 45% to 100%. The problem was still there, after some days the iPhone did restart and showed 0% instead of normal level. And I was not able to charge it again. But I was able to turn my iPhone on and do a backup first. And that is the proof this is not a hardware defect.

Now, after few days thr problem is gone. Maybe because this BAD optimization that kills my first battery is already done.

I think the problem is that the CPU performs a lot of optimization work after updating the iPhone to iOS 14 and kills batteries. And that is not good. At least Apple should start a free battery replacement program for all iPhones updated to iOS 14 and fix this problem with GOOD update as fast as possible.

Hmmm...

that is maybe not the best way to do that. Because after factory reset and restoring your data, the operating system will start with this optimization again.

Better you will try one of these ways:

1. factory reset -> restore data -> optimization time (3-4) days with charger and without the sim card inserted -> normal usage with sim card and the battery level will be calibrated in this time-> done.
2. factory reset --> normal usage and the battery level will be calibrated in this time -> restore data -> optimization time (3-4) days with charger and without the sim card inserted-> put the sim card back (done)

If I were you I would choose the first one.

But there is no special way to do that. It is a Apple Magic! 😅

I wish you good luck! 🍀

If anyone find the solution, please post it here.

Apple Support, that is an huge issue!

My iPhone is just like a brick now!

Please fix it and give me a solutiuon for that!

How exactly am I not able to charge my iPhone XS...

1. I'm not able to turn it on.
2. I don't see the Apple logo at all.
3. I'm not able to get my iPhone in the DFU Mode. https://support.apple.com/library/content/dam/edam/applecare/images/en_US/iOS/ios13-iphone-xs-restore-iphone.jpg
4. ITunes doesn't recognize my iPhone at all.
5. I can see on the display only an empty battery symbol:

• with cable and flash symbol if the charger is disconected
• without cable if the charger is connected

and nothing else happens.

Please Apple fix this problem and bring my iPhone to life!
