iOS 26.2.1 has rendered my phone unusable

Hello,


Since updating to iOS 26.2.1, my iPhone has effectively become unusable.


The update now requires approximately 30GB of free storage, and despite deleting apps and files repeatedly, the issue persists. Almost all of my apps crash, freeze, or become completely unresponsive. The only temporary workaround is rebooting the phone, but the same problems return within 10 minutes.


This cycle repeats constantly:


  • Apps crashing or freezing
  • Forced reboot
  • Temporary functionality
  • Failure again shortly after


No amount of deleting apps or files resolves the issue. This update has made basic phone usage impossible.

This is extremely disappointing and feels like a major regression from previous iOS versions, which were stable and reliable on this same device. iOS 26.2.1 has significantly reduced functionality and usability, and I strongly urge Apple to address this issue or roll back to a more stable version.


At the moment, this update feels unfinished and seriously flawed.

iPhone 14, iOS 26

Yes, I suspect it is your System Data that is growing on your device and gets difficult to manage yourself when you have run into a storage issue and trying to free up space. Apps would crash when there was no room to store their cache data or perform memory swaps, then when you free up space there is room to store those cache files so it fills up again. Any iCloud data that previously was unable to sync to your device would then be able to use that space too.


And to top it off, when you mark data to be deleted, it is not actually removed immediately. Freeing the space so that it can be used for another purpose requires a background process to go through and zero the data that you previously said you want deleted, and that is done when the OS determines it is most convenient by not interfering with what you are doing. The Restore using a computer will get you back on track.

I updated my iPhone SE in December of last year and it died overnight. It could no longer charge, no matter what I did, past 1%.

The post you replied to was for iOS 26.2.1 and that was released January 26 so it is not related to your update and the user was not having a charging issue.


Sounds like a component in your phone failed and that can happen on any device at any time. Since Apple does not do component repairs on the motherboard, the replacement of the motherboard is what would be required. In most cases, it would make more sense to purchase a new phone then spend the money to replace the motherboard. If you had AppleCare, they would have likely proceeded with the repair since it would be covered.

I literally have had this happen on two iphone 14 pro maxes, one had a display issue that caused the screen to mess up, which initialy made me think the issue was the bad screen, but i got a replacement phone , exact same one, via the express replacement service, and it literally crashes editing widgets or editing home screen icons, I can't make up how horrible ios has been across every device I own, crashes in any enviroment constantly and i agree is a major step back.

I was not informed when I got my iPhone, that I also would need to get a computer so that the iPhone would work properly.
so, to eliminate this catastrophic failure. I had to either buy, “AppleCare+” or buy a computer.
green texts are taking over

Huh? A computer is not required for an iPhone to work properly. But a computer can come in handy if you brick your phone from a forgotten passcode, which can help you erase them restore the phone.


AppleCare+ is an extended warranty against accidental damage, so I have no clue what this has to do with anything.


And what does "green texts are taking over mean?" Green texts simply mean they are being sent through your carrier not via iMessage.


Altogether, your post makes no sense. Care to explain what your issue is?

I disagree LD150. My iPhone 11 worked completely fine before the upgrade. Once upgraded, the freeezing, sluggish odd
behaviour occurred and started randomly restarting with increased frequency over the first 48 hours to a point that my battery started to swell. Being an older iPhone 11, I don’t have Apple Care. I made an appointment and took it to Apple Store to which I was told that couldn’t help because the battery was no good. That’s true, but it easily held a full days work prior to upgrade and it wasnt swollen!

Sorry, but you're complaining about a phone released in 2019, seven years ago. If it had the original battery, the update didn't cause the battery to swell. Age and use caused the battery to swell. The battery in your phone likely should have been replaced a long time ago, when its battery health dipped to 80%. You may not like to hear it but neglect is your issue, not an update.

In response to LD150, it may have worked on many other iPhones but Apple pushed this update on old hardware that was working perfectly fine before the update. My iPhone 11 battery health was 97% yet after so much freezing, crashing auto shutdown and restart repeatedly, the battery then swelled and damaged the phone to the point of death. It was a perfectly good phone, good battery, plenty of storage. It only took a few days for post upgrade to deteriorate.


So don’t claim it to be the phones fault, it wasn’t. It was Apple’s. I am on an even older iPhone now as my backup and they still continue to push me to update every day.

I don't buy it. If the battery swelled, it was severely depleted as healthy batteries rarely if ever swell. If it's health was at or below 80%, which was easy to check in Settings > Battery > Battery Health, it needed to be replaced. And there was likely a notification that Service for the battery was required. Could the update have pushed the battery to it's end, yes. But that's not because of an update. It's because the phone wasn't really being maintained.

Agreed! An iPhone 11 that was released 7 years ago and only designed for 500 charge cycles before its Battery Health falls below 80%, is not going to be showing 97% Battery Health unless it was artificially boosted. A replacement of a non-genuine battery may also cause swelling and be a Safety Risk as Apple advises. I suspect the battery needed replaced with a genuine part long ago.


It may have been that the user purchased this phone used and had no idea that the battery had been "boosted" in order to get them to pay more, or had previously been refurbished and not using genuine parts. In either case, that is not the fault of the iOS update and would explain their experience. Sadly, the phone was not properly maintained, whether that was by the user or not.
