I'm inclined to believe what I have experienced. I have never before experienced my 2020 iPad Pro to be remotely slow. I use it for some web browsing and YouTube viewing, so I really don't need a lot of computing power. Now that I'm running the iOS 26 beta, I frequently feel animations going slowly or hitching. It's not terrible, but for the first time, I have the feeling that my experience using my iPad would be not…
Liquid Glass? That's what your M4 CPU is for

#62Written before any beta showed up. Works fine on my M1 Macs sooooo whatever.

#64There's some truth to that, in the sense of "the hardware can handle it now" (but he also mentions Vista, which came out like 20 years ago...)
If it's actually resource intensive, then the logic would probably be "let's make all last-gen devices a bit slower to encourage people to upgrade..."
At least, that's been my experience when upgrading iOS. It's basically the same thing except mysteriously way slower. (I wonder if the CPU throttling thing was part of the iOS upgrade that made my phone slow to a crawl a few years ago.)

#65Earlier quoted context omitted.
If that's so, can't he explain it ELI5 style instead of calling people idiots? I have a hard time believing that the GPU is somehow magically energy efficient, so that computing this glass stuff uses barely any energy (talking about battery drain here, not "unused cycles").
My generous interpretation is that he means the GPU is magically energy efficient compared to the CPU. I wouldn't dispute that. But Apple went down that xPU-taxing path a long time ago when they added the blur to views beneath other views (I don't remember what that was called).

#67As long as it can be disabled it is a complete nothing burger. If it can't be disabled and ends up crippling my otherwise perfectly adequate M1 it will accelerate me to switch to daily use of Asahi Linux. Edit: That's assuming the effects are even expensive for the GPU.
Defaults matter. Most people never change them.

#68IMO the actual reason for Liquid Glass is that they can do it natively. 3rd party UI frameworks can't copy it without a massive performance hit. This brings a more clear divide between fully native iOS applications and React Native -style "build once and cross-compile" -platforms.
Looking back at the announcement, it's more likely that the Management had to decide on the key message for the unveiling prior to the event, and there wasn't much "media-disruptive" to choose from.
So Liquid Glass got elevated to top priority and then all teams got the order to ensure it is present in as many apps as possible.

#69Wasn't that even before the beta was released...?

#70Anyone else get strong GPT5 vibes from this article?
But at this point I'm seeing it everywhere... the "Trash question? Trash answer" format posed as poetry EVERYWHERE and it is correlated with slop and I'm finding it very annoying to read. I might (to my own detriment perhaps) start factoring that in into what I'm gonna continue reading.
Examples of that question format in this article: - Liquid Glass? That's what your M4 CPU is for - That glassy transparency and window animations? A notorious resource hog that brought mid-2000s hardware to its knees - The moment a single tile wiggles? The entire UI crawls - Checking mail? Browsing? Streaming? Your M4 is bored out of its silicon mind - That whole section on: Battery life? ... Thermals? ... Future-proofing? ... Real workloads? ... ugh. - Is it worth it? For Apple’s vibe? Probably. But next time your fan whispers or your battery dips faster than expected… maybe blame the glass.
And apart from that question format, there's another thing but I can't quite figure out the pattern behind it but is slop: (I would really love to figure out what my brain thinks as "off" in these - maybe sentence length variability, maybe colons, or maybe trying to be poetic or dramatic or too self-assured with basically no data/substance underneath it, idk): - Let’s be real: eye candy always comes at a price. - When the system’s stressed, the pretty things break first. - They chew through GPU/CPU time. Always have. - Here’s my hot take: Apple knows exactly what they’re doing - It's stealth bloat. - You might not feel the drag today. That’s the point! The M4’s raw power is the perfect smokescreen. But those cycles aren’t free - TL;DR: Liquid Glass is gorgeous tech debt. Your M4 can afford it… for now. But never forget: fancy pixels demand fancy math.
Basically the entire article at this point. There was one place which was a bit personalized about the web app he built for his kids where I was like OK at least something seems OK, but as another user pointed out "It has those tiles that animate when you hover on them" doesn't make any sense. What tiles. How are we supposed to know.
