iPhone charging issue after iOS 27 update

My SE 2nd gen had this problem after recent IOS 27 upgrade. Battery Max capacity 88%. I had a spare charge cable with 12V plug which did not fix the problem; tried brand new cable with house plug which did not fix the problem. Updated to IOS 27.2 which fixed the problem.

I am pleased to report that the iOS 27.2 update resolved the issue for me as well, confirming that the issue was a bug in iOS release 27.0, not a problem with the health of any of our batteries!

Had the exact same issue with my iPhone SE 2020 and it was super frustrating! But after updating to version 27.2, it's finally solved. As soon as I plugged it in after the update, the charging indicator popped right up and it's working normally again. Not sure if this will fix it for your devices too, but it's definitely worth a try!

Sorunun tıpa tıp aynısını yaşıyorum. Yorumlarda pil sağlığı vs. yorumlara aldırış etme. iOS 27 Türkiyede kullanıma sunulduğu gün kullanmaya başladım ve sorun o andan itibaren başladı. Kendim türkiyede Apple Özel Teknik Servisliği yapıyorum. Orjinal pilim 87’ydi, pili değiştirdim. Düzelmedi. Sonrasında başka Teknik Servis arkadaşlarla görüştüm. Bazıları Şarj Soketi arızalı dedi. Bazılarıda Anakart / Şarj Entegresi Arızası dedi. Herkes yazılımsal olması imkansız dedi. Sonrasında İtunes üzerinden İos 26 ya düşürdüm. Sorun düzeldi. Ondan sonra tekrar İos 27 ye güncelledim. Sorun tekrar ortaya çıkınca tekrar sürümü düşürdüm. Ancak bir gece uyurken telefonum otomatik olarak kendiliğinden İos 27.0.1 e yükselmiş. Ve sabaha kadar şarjım hiç dolmamıştı. Tekrar sürümü düşürmek istedim fakat İOS 26’ı için  desteği kesip imzaları kapattığı için düşüremedim. Düşürenler var ama jailbrek gibi işlemler yapıldığı için güvenilir bir işlem değil. O yüzden yapmadım. Şuanda yeni güncellemelerle düzelmesini bekliyorum. 27.0 ve 27.0.1 de düzelmedi. Umarım Apple bu durumun ciddiyetini farkedip SE için bu düzenlemeyi bir daha ki güncellemede yapar ve bizi bu durumdan kurtarır. Sizede tavsiyem cihazınızı onarıma vermeyin kesinlikle güncellemeyi bekleyin.

I had the Apple Store replace the battery on my iPhone SE 2nd Ed (2020) on 9/13/26 and I updated the operating system to iOS 27 a couple days later. I immediately encountered the same charging issue described here. It charges perfectly normally with any USB-A to Lightning charger, including higher-voltage USB-A fast-charging ports on my computer. But if I plug it into any USB-C to Lightning charger, it charges for exactly three seconds and then drops the connection.

Thinking the issue was a botched battery replacement, I brought it back to the Apple Store for a warranty claim on the battery service. They put in another new battery and ran full diagnostic testing and did a full software reinstall. They found no visual evidence of damage or shorting. They said it is able to accept fast charging through Mag Safe and can charge fine from USB-A, but they confirmed it will not charge from USB-C. They were unable to isolate the cause. The only explanation they could think of was short on the logic board, but they claimed there was no way this could have happened during the battery replacement.

Sounds like I falsely accused them and it was the iOS 27 update all along!

Sounds like your battery is failing. What is the battery health percentage? If it is below 80% it needs to be replaced. The other problem may be the cable itself or the port on your phone. You can have Apple perform diagnostics on your phone for free.

• Genius Bar Reservation and Apple Support Options - Apple
• Contact Apple Support - Apple Support

Not strange at all. iOS 27 is demanding, and your battery was on the verge anyway.

Check your Battery Health settings to see that the things are not "Normal" anymore with your battery.

A new battery will be about $70-80 U.S. at the Apple Store / Genius Bar or an Authorized Apple Service Provider (AASP). The Genius Bar will require reservation. Most other shops will not.

I’m going through the same thing right now. Hopefully this issue gets resolved.

It is either your Battery, whether it has been replaced using third party or showing a poor Health percentage, or like was previously posted a cheap charger/cable that is not MFi certified may be problematic.

It would not be unusual for every iPhone SE 2nd generation to have needed a battery replacement by now and even before the iOS update where it would be showing the Service message in the Battery Settings. It was first released 6 years ago and discontinued 4 years ago where it was only expected to last 500 Charge Cycles before needing the battery replaced.

Some days ago I also complaint here about this issue. I have just installed 27.2 and the problem is fixed. It charges both with fast and slow chargers without problem again. Thank you all for reporting and creating this conversation, I have been very close to buy a new iphone as I was desperate with the charging issue. You have saved me a lot of money :))))))))

I found another work around. If I use an USB-A lightning it charges without any problem if I use an USB-C Lightning it stops when the remaining charging time appears

FİXED AFTER İOS 27.2

Your SE is 4-6 years old depending on when you placed it into service.

The battery in the SE was designed to go 2-3 years with normal use.

You have done extremely well and it is remarkable that you have not had battery issues until now.

The battery is very likely overdue to be replaced.

That is not unusual. Your battery was failing before the update where you also likely have the Service message listed next to the battery telling you it needs replaced. Any additional demands on a failing battery, including those placed on it from an update, is going to have unexpected results.

Think of your car battery, it may be working just fine when driving around in daylight, but once it gets dark and you need to place those additional demands on it or if it gets colder than usual overnight, it may not start in the morning or even hold a charge. Of course it is not because it was dark or cold that caused your battery to fail, it was because it needed to be replaced earlier.

Have this exact issue right after ios 27 update. I also tried different cables but its not about cables. It actually charges but doesnt show the charging animation. If u leave it on charge and restart after a while it shows the real percentage. Also no problem with data transfer. Cables works just fine with data transfer. And it works normally with powerbank too , so it is a software issue that apple ignores for weeks lol. I dont know why it works just fine with powerbank but not with charging brick. I use original brick and cable and many se 2020 user experience this problem. Reminding you this started right after ios 27. It is not a battery issue , its almost brand new. i changed battery like 6 monhts ago. There is many .entries about this on reddit. I just did the last 27.0.1 update hoping it would fix it but its the same. HELP @apple

Read the last few posts (you need to set your thread sort to Oldest) yes it was fixed in iOS27.2

27.2de düzeldi benimki sonunda. sabah yaptım sorun yok şu ana kadar

I have a SE 2 which has a perfect daily charging history, until updating iOS 27/27.1, whereby battery is not charging when plugged in - my capacity is 89% - i discovered connecting the phone to my MacBook Air works way better - Apple still hasn't corrected the issue, and appears the issue is particular to SE 2 ...

I am also having Exactly same problem.

• What is your Battery Health at Settings > Battery > Battery Health?
• Did you let your phone completely discharge where it shut off? If so, it may take a slow charge, such as that with a computer, to jump start your battery so it will take the amperage of a fast charge.

It is a software issue. The workaround I found was to open the Bastet status and then plug in the charger. If not open the issue will be there when the charging time will be displayed if open it will display charging time correct and continues. So bad code and no bad battery whatever they claim

nah thats just sloppy work. this morning i did the 27.2 and it fixed now after monhts. tho when i contacted apple support they were telling me because i was using non apple battery without diognostics :D. Ive been chaging my own battery over the years and now it started to cause problem? :D. guess not buddy

Hi from Spain. Same problem here. My iPhone SE 2020 was charging perfectly and suddenly after the update to iOS 27.0.1 doesn´t charge with the charger I usually use (fast charger and cable usb-c to lightning) As others here say, I connect it , it starts charging and after about 3 seconds the charging icon in the battery disappears. After many times, randomly and only sometimes, I finally charge it, so it is is BIG problem, you don´t know whether your mobile is going to be available or not!!

PLEASE APPLE solve this issue ASAP, it is not a battery problem as many people here are reporting (I haven´t changed my battery, I have the original one and it was working perfectly for the age it has before the iOS update). I don´t want to buy a new phone due to a problem that I haven´t created!!

The solution i found is slowly charging it through usb connected to the pc. It takes hours. It seems only fast charging from the charger is the problem. The experts here dont help. They deny reality.

Same happened to me and tried numerous attempts fortunately it will charge with USB A cable, very frustrating.

As batteries age they chemically change and become less stable and predictable. The algorithm Apple uses can’t be as accurate because the battery no longer behaves in a predictable manner. Replace the battery.

Same problem, my se 2 have just got outside battery replacement (unknown parts) for about 1 month, evey things work well in ios 26.6, but when upgrade to ios 27, i encounter the same problem as many one here, battery is actually charge but not show out, the phone need to be restarted to update the current battery status

This means you had the battery replaced NOT by Apple or an actual Apple Authorized Service Provider and you don't have an authentic battery in your phone. Take it back to whoever you paid to replace the battery. Apple won't touch an iPhone with 3rd party parts installed in it.

It’s not just an issue with SE. My iPad Air m4 and iPhone 15 both now have this problem after updating to os27. I bought a 24w usbc supply to resolve the issue but the problem still occurs intermittently and I have to unplug the devices and try several times to get a successful charge. Swapping leads has also worked. On my iPad I also get a liquid detected warning. Both devices are brand new and I had no trouble charging until after the update. Hopefully Apple will fix this, otherwise they’ll be getting back both devices.

I am also having issues with battery charging on my iPhone SE model MX992LL/A AND replaced the battery two months ago. Coincidentally, I noticed the diminished battery charging after upgrading my phone to iOS 27. The Genius Lab did not identify damages to the charging port on the phone. Several different charging cables and charging blocks have been used as well. I’ve written to Apple’s feedback page to please investigate this issues since it appears that other users are experiencing the same problem.

The iOS 27.2 update seems to have fixed the issue. Ergo, it does not seem to have (at least entirely) been the fault of old battery age, third-party chargers/cables, third-party battery replacement, etc.

I have the same issue. The phone starts charging suddenly after connecting to the charger but stops charging quickly. I tried to charge the phone using a laptop instead of a charging dock. The same thing happens. But the interesting thing is only charging stopped and phone not disconnected from laptop. Also, a normal 5A charger works. Only fast charging is not working. I'm pretty sure the problem is in the iOS software, not in the charging port.

Try going into settings, battery, turn off percentage. I’ve just done this and it has fixed the issue on my se gen 2.

was not charging through the c charger after latest iOS 27 update.

I have the exact same problem! Since updating to iOS 27, the charging animation lasts a few seconds and then stops, even though the iPhone is charging. Worst than this, is the uncertanty in the battery percentage I have left, since it always display a random percentage... I've been through a whole day, with the iPhone displaying 4% battery... This is happening on an iPhone SE 2nd generation, with a very recent battery that had no problem on iOS 26

I am having same problems. Its only charging when I am attaching the lightning to usb c cable from the iPhone to MacBook. Its presumably charging at 5W but surprisingly it charged upto 80% from under 20% in few minutes. After 80% it slowed down possibly due to optimising battery tab being on. Its not charging with 35 w wall socket apple charger. It goes green for 2-3 seconds and then stops. My battery has 100% battery health so its not a battery issue.

Does the algorithm change with iOS updates?

Yes, Apple refines the algorithm as data is acquired from each specific model battery. It’s not a one size fits all. The algorithm is also a smart algorithm, meaning it learns about your specific battery, use conditions, storage conditions and modifies the charging to best adapt to the current battery conditions.

So, after an upgrade or update, charging and battery behavior may change. In general the algorithm becomes more accurate, law of large numbers. The more information and larger the sampling group the more accurate the results.

It is ether a BUG or apple is preventing us from using random chargers. with original cable it works, but with a usb to lightning is starts charging for a second and disables. For sure it is software related. it started right after 27.0.1 update. battery health is 86%. Maybe they are trying to force us to change the battery...

I am having the same issue. It was charging okay before this update. The cables I use are fine. One of them is new. The phone was replaced by Apple a few months ago. So, it isn’t the battery. It definitely appears to be a glitch with the new update, which I hope another update with a fix is released asap.

I contacted Apple official support, the person was very polite and tried the most to be helpful.

I described exactly this issue, send videos, photos, etc.

To my great surprise I was told that there is no official complaint, worlwide, regarding this issue.

The best way to get Apple to release a fix for this is if everyone having this problem reaches out to the official support channels.

I conducted a thorough search of this forum using the term 'Charging Issues after iOS' and uncovered numerous posts detailing similar issues across various iOS updates. This suggests that iOS updates may not consistently be the root cause. Below are a handful of examples extracted from the search results:

These are just a few examples....

Reports of device lag appear across all models and iOS versions in this forum, suggesting the issue is device-specific rather than tied to any particular iOS version or model.

Seems like the same issue as here: Problem charging iPhone se2 in ios27 - Apple Community.

This is an iOS 27 issue regardless of battery age.

Not a battery issue

Read bnt789’s comment above. It’s not an “old battery” or “unauthorized battery” issue. It’s an issue with 27.0.1 and I wish I had not updated!

This discussion thread may help you --> iPhone SE (2020) charging issue after iOS… - Apple Community

I have a similar issue on iPhone SE2 iOS 27.0.1.

When charging via USB‑C PD fast charger, the hardware charges normally, but the system UI fails to refresh: no lightning icon in status bar, lock screen battery percentage stays frozen. The real battery level only updates after reboot.

I have the same problem with an iPad 9th Gen that has a newer battery, it charged perfectly before the latest iOS 27 update. Now after the 27.0.1 update it won’t wake up from a discharged battery to charge.

I am also having Exactly same problem. Today morning I updated my iPhone 14pro to iOS27 and after that my iPhone is not charging when I plugged in it gets charge and quickly not charging. This issue is only iOS 27 and right I am regretting to get an iPhone and also update to iOS 27.

Right now I am so frustrated and my work got stucked, what to do now I don’t know and when apple gives us new software update to fix this problem

Hi, i am using mopai kt393 which is listed on apple mfi devices list in web. My phone is 14 pro(ios 27) and cannot be charged via mopai kt393. I tried to use another phones : 14 pro(ios 18), 13 basic(ios 26), they were charged normally. Is this a bug of ios27? or new rules on ios 27? or mopai kt393 is actually not a mfi device? Anyone has this issue too?

I am also have iphone SE 2020 and when I am plugging in charger it start charging for 2-3 second then stop charging and I need to unplug and replug at least 4-5 times sometimes 15-20 times to make charging stable. This issue started occuring after ios 27 update before ios update I have not faced any such issue. I tried changing data cable as well as charger adapter but same issue.

Same problem, my se 2 have just got outside battery replacement (unknown parts) for about 1 month, evey things work well in ios 26.6, but when upgrade to ios 27, i encounter the same problem as many one here, battery is actually charge but not show out, the phone need to be restarted to update the current battery status

I have the same exact issue with the same iPhone model and iOS version, except that mine doesn’t charge from the laptop at all anymore immediately after upgrading. I normally charge the phone from my laptop as I work and only top up later if required but I now always also need a brick and a wall power point to charge. But even that is a pain to get it work sometimes!

Why will it charge correct when you open battery status before charging ? It fails only if battery status is not open and then exactly at the time when it will display the charging time. Bad code is the conclusion

I’m having the same exact issue with my iPhoneSE since the iOS 27.0 update and it doesn’t matter what charger I use—actually my old slow charger is the only one that currently doesn’t constantly drop the charge. My battery health says 97%.

Yes, thanks, we know now, we didn't in September.

Yeah, my battery health is below 80% but then it was working perfect until I updated to iOS 27, that very strange.

Same, never had an issue until this update.

Me too. I have an iPhone SE 2gen

agreed, it definitely looks like an iOS 27 issue.

But the issue didn't start till AFTER the iOS update.

Does the algorithm change with iOS updates?

I’m going through the same thing right now. Hopefully this issue gets resolved.

Same here. Happening to almost every device running it and days at most after updating each one it begins. Happening to multiple generations of iPad Pros including my 2024 one.
