OK so first off, I'm new here. I am the furthest possible thing from a blind hater (or fanboy for that matter).
Apple is just a company, made up of a lot of people.
Not only have I had only an iPhone as my primary mobile device since the 3G / 3GS; I've also had the iPad since the very first one. (I just unearthed my original one, actually!!)
Not only that; currently, in active use / service in my house, we have 13 iDevices.
THIRTEEN.
All actively in use (in different ways & by different people. YES, I need to trim that down because it is ridiculous. Don't judge me...)
I feel this is important so you know I am a long time user of Apple products, and in fact firmly believe they are the best mobile devices + Mobile OS on the market, period.
That said;
iOS 26, has, without a doubt, been the absolute worst, most awful, terrible, steaming pile of garbage I've ever seen Apple release in almost 20 years.
The very first version of iOS 26 released by Apple last fall; lets say its 26.0.0; was not even Alpha software. It was so awfully unstable, buggy, glitchy. It literally KILLED my 11" M1 iPad pro & I STILL regret updating that iPad, to this day. I did NOT update my 13" M4 ipad, and never will let iOS 26 touch my M4 iPad. Not sure if i'll even update to iOS 27. Apple has destroyed my trust in them to release an OS that isn't a nuclear disaster.
Specifically; iOS 26 on my 11" M1 iPad Pro (a fine, if no longer cutting edge device; but it ran iOS 18 perfectly fine) KILLED the battery. My 11" M1 iPad went from a typical 10+ hour battery, to 3-4 hours - TOPS. Probably even less.
I was too upset to sit & time it with a stopwatch. I could literally watch the battery tick down fast.
The past week, on multiple occasions, my wife & I have been sitting right next to each other, and both our phones got so hot to the point they overheated & shut down temporarily, which was PERFECT timing right in the middle of my child's play. Thanks apple.
Never had that happen before, esp. not when I was literally sitting & just taking some photos & video. And I've definitely never had the same thing happen to both mine & my wife's phones at the same time. Yes of course, I restarted them (I restart all our iDevices multiple times per week just to keep them all running smoothly).
FINALLY just now, the other day, when iOS 26.5 came out, FINALLY it improved the battery, so it lasts more than just 3-4 hours - on my iPhone 16 Pro and iPad 11" M1.
Another super annoying issue that persists across all iOS 26.X updates and on both my iPhone 16 Pro and 11" M1 iPad Pro is rearranging / re-organizing home screen icons feels like the device is stuck in molasses, with some gravel throwin in for good measure. Basically and overall; the #1 top thing I've always appreciated about iOS over Android; how buttery smooth that is; Apple clearly internally changed their definition of "smooth" to include molasses, tar, sand & gravel.
Little things (which aren't quite so little in practice) like the search button / box / bar shows in totally different places across apps. Searching inside the Apple Reminder app is mostly an exercise in futility. I need to either go to another device & search, or force quit & re-launch the app, or just clear out & re-type my search query multiple times.
I do absolutely LOVE how Apple finally created "urgent" reminders (alarms) in the reminders app. That has truly, literally been a game & life-changer. Combine that with Fantastical's support of the same for calendar events and honestly; it's seriously improved my life & work in meaningful ways. Truly.
Other significant bugs in iOS 26 (and DEFINITELY iOS 26); anytime I've been on any sort of a call; phone (cellular); Teams, Google Meet, Zoom; anything; anytime an alert / alarm fires, or is about to fire (about 1-2 seconds before) the call audio goes all crackly & staticky and fully cuts out as the alarm / alert is firing. This is not just me; many MANY others I've been on calls with have said; "excuse me? You cut out; are you still there?"
So its NOT just me / my perception.
I can absolutely keep going, but I'll stop there.
Summary; iOS 26 is hot garbage (or cold garbage; whatever you find more offensive).
I am very glad to hear that iOS 27 is supposed to be a "focus on performance & bug fixes, not so many new features" release.
I've also always been incensed at how Apple seems to CONSTANTLY - with almost EVERY iOS update; not just major releases like going from 18 to 26, but 26.0; 26.0.1; 26.0.2; 26.2; etc. etc; apple seems to CONSTANTLY roll out new emojis, wallpaper & similar banal garbage like that.
IDC how few people work on that; those people's jobs either shouldn't exist, or they should be repurposed to, oh, IDK, making sure that my almost $2k phone can, you know.....MAKE PHONE CALLS......
