In The World of Foldable Smartphones, 0.1mm Can Mean Everything?

Samsung unveiled its slimmest foldable, the Galaxy Z Fold7, on July 9, 2025. But before the spotlight could settle, Honor chimed in on X, formerly known as Twitter, with a sly video. In it, ChatGPT o4-mini declares the Honor Magic V5 as the world’s thinnest foldable at just 8.8mm when folded. Samsung’s Fold7 was placed second, and Honor captioned the video with “Their words, not ours.” It’s a subtle jab, but the intent is crystal clear.

X users have had a field day debating whether this wafer-thin difference really matters. Here’s what people are saying and what I honestly think about this blink-and-you-miss-it difference.

You Bet the Internet Chimed In

Honor’s little flex didn’t go unnoticed. After posting the AI-assisted dig at Samsung, users on X flocked to the comments. Many were seen asking about the global availability of the Honor Magic V5 and the kind of software updates and support the company actually provides.

Meanwhile, others weren’t holding back. They took the opportunity to poke fun at Honor instead, questioning the ad’s credibility and blaming AI for throwing out inconsistent answers like it’s playing a game of spin the bottle.

Curiosity got the better of me, so I gave it a shot. I threw the same question at ChatGPT, and guess what? It crowned the Samsung Galaxy Z Fold7 as the top pick in the premium foldable segment.

ChatGPT’s answer to the same question

To top it off, a few users even called out Honor for stretching the truth. Not my words, by the way. That’s straight from the X community. I’m just here with the popcorn.

Is 0.1mm the New Flex in Foldable Phones?

Look, I get it. Foldables are clearly hitting the gym. Every brand, whether it’s Samsung, Honor, or Vivo, is on a mission to shave off every possible millimetre from their foldable phones. And now, “world’s slimmest” seems to be the new favourite buzzword, just like we once obsessed over how many megapixels a camera had or how fast it could charge from 0 to 100.

But between you and me, a 0.1mm difference? That’s basically the thickness of a fingernail. Are we really going to throw shade over that? Some folks on X don’t think so either, and honestly, I agree.

Sure, a sleek foldable is always nice. It feels fancy, slides into pockets like a dream, and yes, it’s a great conversation starter. But when I’m out all day running around, what I really care about is whether the phone keeps up with me. I need smooth performance, cameras that don’t mess up my one good selfie, and battery life that doesn’t force me to carry a power bank. Also, let’s not forget software. A super slim phone is great until it starts lagging when I open Instagram, or takes forever to switch between apps. Worse, if the battery doesn’t last me an entire day. That’s when reality kicks in.

So, yes, brands can continue to battle over fractions of a millimeter if they want. I’ll be over here, rooting for the phone that doesn’t give up before my day does.

Samsung Galaxy Z Fold7 Design

On the contrary, Samsung, for instance, has had over seven years to refine its fold phones. Just comparing the Fold6 to the Fold7, you can see how much has improved, not just in thickness but in usability. So if brands are improving where it counts, that’s what really matters to a customer.
