There are rumors, whispers and speculations: 2025 is supposed to be the year of ultra-thin smartphones, where thinness means more than just design – it means a blueprint for the future of foldable devices. While most of the details - ultra-thin phones 2025 - remain shrouded in a fog of rumors, the iPhone 17 Air and Galaxy S25 Edge already hint at a new era of lightness and flexibility.
Ultra-thin phones 2025?! If you believe the rumors – and let's face it, in the tech world we often have no other choice – then get ready for a new era of smartphones, where thinness will not just be a fashion accessory, but a strategic step into a new era.
iPhone 17 Air, Galaxy S25 Edge and, of course Motorola Razr Plus 2025 are the main stars of this year's casting. While most of these devices only exist in the form of sketches, renders, and leaked measurements (at best on YouTube and Xu), the trend is clear: the phones will thinner, lighter and – at least we hope – smarter.
Ultra-thin phones 2025?! Why is everyone getting thin? Short answer: because it's time for a change.
Ultra-thin smartphones are the logical next step after years of phones getting thicker, heavier, and—let's be honest—quite cumbersome. Advances in materials (read: more titanium, less clunky alloys) and the efficiency of new processors (3nm and beyond) are allowing manufacturers to create something that's both stylish and powerful.
And yet – almost everything we know about these devices today comes from semi-official sources: leakers like Sonny Dickson, analysts like Ross Young, and the occasional misguided “forgotten” YouTuber. The real specs? Still far from confirmed.
iPhone 17 Air: Future-proofing
The iPhone 17 Air is said to be ultra-thin (~5.5mm), with just a single 48MP rear camera and a modest 3,500mAh battery. Some sources say it's a minimalist attempt to conquer the market, while others see a deeper plan: make the iPhone thin enough to go foldable next yearSo – Apple will make 1/2 of the future foldable phone this year.
If the rumors are correct, then the Air isn't just the thinnest iPhone ever—it's introduction into the first Apple foldable device, expected around 2026.
Aluminum frame? Cheaper, lighter, perhaps less durable – but perfect for a thin and flexible design.
Galaxy S25 Edge: Samsung's beautiful but perhaps imperfect solution
Samsung is also playing the thinness card with the Galaxy S25 Edge (~5.8 mm thick), with Snapdragon 8 Elite and dual camera.
Critics are already noting: it lacks an ultra-wide lens, the battery is “only” 3,900 mAh, and while the design is impeccable, the question remains: how much functionality are we willing to sacrifice for beauty?
And again – everything we know is based on renders, rumors, and slightly overly optimistic “inside” sources.
Motorola Razr Plus 2025: The only one with a plan (and already implementing it)
While Apple and Samsung are still negotiating their ultra-thin philosophies, Motorola is already delivering. The Razr Plus 2025 is said to feature a 4,275 mAh battery, a triple camera, and an improved foldable design.
Sure – we're talking about leaked specs. But Motorola has proven over the years that it can bring innovation to market before others even understand what they're looking at.
If you're looking for a device that's lightweight, powerful, and future-proof, then the Razr Plus 2025 looks like the safest bet.
Why this isn't (yet) the finished story: Ultra-thin phones 2025
It is important to emphasize: most of the information is based on rumorsAnd in the world of smartphones, that means two things:
- 80 % of this will be true somehow.
- 20 % of this will be completely wrong (and we will all be surprised, of course).
But the trend is strong enough to be ignored. Thinness, lightness, preparation for foldables – all of these will shape smartphones in the years to come.
Ultra-thin phones are “in” again – but this time they’re not just a fashion accessory. They’re pre-preparation to devices that will soon be more flexible, smarter and, hopefully, a little less boring than those giant “phablets” we’ve been carrying around for the last decade.
Conclusion: A Bright Future – Ultra-Thin Phones 2025, with Some Tough Questions
2025 will be the year that phones start losing weight again – both physically and literally.
Although today we only know most of the details through social media noise and "confidential" PowerPoints, one thing is clear: ultra-thin phones are not just a nostalgic homage to the past, but a bridge to the future.
And the next time you hear rumors about an iPhone that's so thin you could use it as a bookmark in a book - don't be surprised. This is just the beginning.
