iPhone Charging Slowly Or Very Slowly After iOS 16 Update?
iPhone charging slow iOS 16
iPhone charging very slowly after update? You’ve recently updated to iOS 16 or iOS 16.1 and your device is charging very slow when connected to a 20W power adapter? Battery charge increasing by only 3% in 20 minutes? You’re not alone!
iPhone Charging Slowly In iOS 16?
This issue has been reported by Mohamad (iPhone XR, iOS 16.1):
“My phone is charging very slowly using type-C to lightning cable (only 3% within 20min). The issue started after updating the iPhone from IOS 16.0 to IOS 16.1.”
We couldn’t replicate this problem for the time being, but have found a similar complaint on Reddit:
“16.1 my XR takes way longer to charge (if I’m using it, it’s 10 minutes or more for 1% without heavy load) and battery life also seems quite a bit worse.”
It’s not clear how widespread this unexpected behavior is. Both reports are mentioning the iPhone XR!
If you’re experiencing the same please mention it in the comments. Do mention iPhone model and other useful details that can help us report the bug accurately to Apple.
How To Fix iPhone Charging Slow
The first thing that you should try is rebooting your device. A fresh start could clear any minor glitches that might cause the iPhone not to charge properly.
Tip: We recommend you to use the force restart combo for quick results.
If this doesn’t work try different charging options which include:
- Charging using a computer: connect iPhone to a Mac or Windows computer using a Lightning to USB cable and the device should start charging.
- MagSafe charging (if supported): requires Apple MagSafe charger.
- Fast charging: requires 20W USB-C power adapter and USB-C to Lightning cable.
Other Fixes For iOS 16 Slow Charging
If nothing from the above works you should also check potential hardware issues:
– Clean the iPhone’s lightning port. You can use a toothbrush or a custom Lightning port cleaning kit.
– Make sure that the device is in an environment with normal temperature. If it’s too hot or directly exposed to sun it will overheat and charging might be put on hold until it cools down.
Conclusion: If nothing helps we’re most likely dealing with a software glitch that has to be fixed in an upcoming software update.

The same thing happened to me after updating to 6.1 on my iPhone XR I noticed that the rate of charging was slow in the Settings>battery graph slope. Yet when I restart the device and then check later, the rate of charging (slope) is back to normal. Unfortunately this means I’m restarting my phone several times a day now.
That must be annoying. Are you using a genuine Apple charger?
I got new lightning cables and blocks and still same thing.
Thanks for mentioning.
I’m also having to restart my phone a bunch of times as well!!
I have the same problem – my iPhone XR charges super slowly since the update to 16.1 – also charging with lightning cable via laptop is very slow
I am experiencing the same issue, my iphone XR is often not charging or charging very slow via Imac Usb-c after update to ios 16.1.1. Sometimes restarting or charging via other sources helps, but surely this is not hardware related. I am using a genuine and recently bought Apple charging cable. Very annoying, as well as are the other artifacts of update to 16.1.1 (background image lost, clock giant font size).
Thanks for the feedback Angelika. This has been reported. Please try a wall charger until this is fixed.
Can you please detail the Clock giant font size issue. Eventually, share a screenshot with us at contact[at]iphonetricks.org?
I have an IPhone13 and it charges really slow or barely at all after the IOS 16 and 16.1 and it drives me nuts. I got new lightning cables and blocks and still same thing.
Sorry to hear this. I assume that you’ve also tried to clean the charging port?
Is the charging slow for both Lightning and MagSafe?
Yes I have, even with compressed air!!
OK. Thanks for the follow up. Not sure what else to suggest. Stick with MagSafe until the next software update. Let us know if anything changes.
When is the next software update coming after IOS 16.0 coming out?
we had iOS 16.0, iOS 16.0.2, iOS 16.0.3 and now iOS 16.1. You can get the full timeline here:
https://www.iphonetricks.org/ios-16-features-list-popular-hidden-unknown/
We expect iOS 16.1.1 with bug fixes sometime in November.
iOS 16.2 is currently beta tested and expected for December 2022.
Regarding the charging options, Mag safe seems to be ok but it’s the lightning cable seems to be having the problems
Also, using my phone while it’s plugged in it charges hardly at all. It never has done that before. When I used it while it was plugged in, it would charge up really fast while I was using it.
iOS 16.1.1 has been released with bug fixes. Does it help?
Haven’t done it yet. I will tomorrow
Not even a tick of difference 🙄🙄
Sorry to hear this. Not sure what else to suggest. Do you have an Apple Store nearby to have the hardware checked out?
It’s not cleaning port or other excuses. My iPhone 13 started dong this 2 weeks ago. Drives me nuts. Only charges 10% after 2 hours. Then I use it and it drops by 5-10% after 2-3 minutes of use. There is a bug or something in 16.3 or 16.4??????
Have you managed to fix this in the meantime? You might be facing a hardware issue.
I’m having the same issue too when charging with my lightning cable to laptop. It’s taking half an hour to charge 3%! It’s marginally faster if I use a plug. I updated to iOS 16.1 last night and have an XS. I don’t have a MagSafe charger to test whether it’s faster with that or not 🙄
Thanks for confirming. I don’t recommend MagSafe charging with the XS. It’s not coming with a magnet and native support for Wi-Fi charging.
Same issue here. Charging iPhone XS on Mac Mini USB C port is often very slow. Cleaning the lightning port is not the solution, this is a software issue. Restarting the device is the only workaround.
It’s a bit strange that Apple doesn’t test stuff like this before releasing an update.
Thanks for the feedback. What’s even more strange is that it only affects a small part of devices. We couldn’t replicate it for example.
Iphone 8plus here. Same issue with charging, so far plugged in over an hour and its gained 21 percent. Never had an issue until this update of IOS 16 and 16.2
Thanks for sharing. Have you tried cleaning the Lightning port?
iPhone 12 with latest update 16.1.1 phone now very slow charging.
Have you tried force restarting the device?
I too am having slow charging issues. It was fine before update.
Can you mention iPhone model please. Does it get fixed if you restart device?
Same happening with me iphone xr, the latest update makes no difference. Cant even downgade now as apple have stopped signing ios 15😡
Sorry to hear this. I have some ‘good’ news though. You can still downgrade. Here is how to:

I am having problems charging my 13 pro after I installed 16.1.1 update. It never used to have these problems before. I have tried changing chargers and rebooting its not working
Thanks for reporting. You’ve updated from iOS 16.1? It’s still signed. You can opt to downgrade.
Im having the same problem charging really slowly after update, i have an iPhone XR. although its charging fine when i charge it from my iPad.. not sure if its the iPhone or update on my macbook.
Thanks for sharing. Someone suggested that charging works at normal pace if the phone is switched off before connecting to the power source. Of course, that this isn’t an acceptable workaround, but can you test it out please and let us know if you get the same behavior?
I’m having the same problem charging really slowly after update to 16.1.1 i have an iPhone XR (10). Charge it with lightning on iMac. I have tried restart and clean but no different. Took all night to get to 75%. Agree it is Apple software.
Thanks for confirming. What happens if you try a wall charger?
This slow charging is occurring with my iPhone 13 Pro. As soon as I updated my phone to 16.1, it started and continues. Right now, I have 16.1.1 and it’s still slow. This is BS and I miss Steve Jobs everyday!
Thanks for sharing Marcus. Can you please try to switch your device off and plug it in while turned Off. A reader suggested this workaround, until a permanent fix is issued. We’re curious to find out if it works for you too.
IPhone 12 Max Pro – IOS- 16.1.1 – 1st thing noticed wasn’t charging through port. Powered down and restarted. Still not able to through port. Was able to charge through wireless pad but it was slow. Today it is charging through port but very very slowly. It is also getting very hot. I’m will to help troubleshoot if you have ideas.
Try to clean install iOS 16.1.1. Reinstall using computer:

I have iPhone XR and iPhone XS, both are experiencing very slow charging as reported by others. But I am experiencing it only if I try to charge via my M1 Mac Pro, if I connect lighting cable to wall adaptor (Anker) then it is charging fast.
That’s an interesting information. So this looks more like a macOS Ventura issue.
After updating to ios 16.1.1, iphone 14 pro max is charging very slow. From 30% to 96% in 4 hours.
Thanks for reporting. What charging option are you using? Wired, wall outlet?
I’m having the same issue on my XR after updating to iOS 16.
I have many usb C to lightning cables and have tried from either Mac or my battery pack, and my phone hasn’t been at 100% in days.
Thanks for reporting. Is charging from a wall charger working normally, at least?
14 pro here. Unable to fast charge now using a PD charger and MFI certified cable. Charging at 9-12W (Measured using Charger Master)
Thanks for reporting. You’ll have to use the cable that came with your iPhone until a new software update will address this issue.
I’m having the same issue on my iPhone 11pro. 0 to 30 percent takes 1 hour . And full charge takes almost 3 hours. And stucks on 95 percent the in restart my phone and its 98 or 100. But the the battery doesnt drain fast and works reallly good. Im on ios 16.5 and i use genuine apple 20w charcher with apple type c to lightning cable.
Have you ever replaced the battery? What’s the health of it?
