The mobile phone manufacturers decided this 2025 would be the year of ultra-thin smartphoneseven if no one had asked for them. And we know that’s true, because most of them sell for less than old, stale bread at a bakery. However, brands have decided to start their career and more and more are joining together.
The most famous representatives of this segment are the iPhone Air and Galaxy S25 Edge, but What other options are there? This is what we will talk about in this article, in which you will learn the five thinnest phones in 2025 which, moreover, are not foldable.
Huawei Mate 70 Air: a huge battery and the best cameras
The Mate 70 Air opens this article because Its thickness of 6.6mm is the largest. However, there are two elements that influence this parameter and seem like a gigantic result to us: the cameras and the battery, which are the best on the list.
Huawei provided this device three rear cameras of 50 MP + 12 MP + 8 MP. All with exceptional quality and including a telephoto lens (it is the only ultra-thin cell phone with this type of camera).
Meanwhile, the battery has a capacity of no less than 6500 mAh and with 66 W fast charging. That’s really crazy for such a thin smartphone! And mind you, the Mate 70 Air has a Full HD+ OLED screen, frequency up to 120 Hz with LTPO and a peak brightness of up to 4000 nits. Yes, it’s a very comprehensive panel, but there are still things to say.
Among its other notable specifications are up to 16GB of RAM and up to 512GB of storageHiRes audio, IP68/IP69 protection, HarmonyOS 5.1 and satellite connection (in China). Its price? Starting from €510 at the exchange rate, although we doubt it will ever arrive in Spain.
Motorola Edge 70: a point of balance in many things
Against a thickness of 6 mm and a weight of just 159 gramsthe Edge 70 is the lightest phone on this list. However, we dare to say that this is the least of it. Why? Because Motorola sometimes goes crazy with its prices, but other times they shine. The Edge 70 is in the latter group because, Despite costing €800, it is a device that shines with its own light.
In it you will find three 50 MP cameras (two behind), 68W fast charging and 15W wireless charging4800 mAh battery, 12 GB of RAM and up to 512 GB of storage space, in addition to pure Android 16. Furthermore, an excellent processor such as the Snapdragon 7 Gen 4, a 120 Hz and Full HD+ P-OLED screen, as well as Dolby Atmos sound.
And in case you were worried about its durability, it turns out that it is It has IP68/IP69 protectionbut also MIL-STD-810H certification. Come on, it’s a rock.
Nubia Air: the cheapest ultraslim ever
The air of Nubia It is only 5.9 mm thickwhich leaves it as the center point of this list. However, with a price of only €180 (currently)It’s also the cheapest and most modest in specs.
This device has a Unisoc T8300, an entry-level chip that works very well in basic tasks, but not for much else. Even so, the Nubia Air has 8GB RAM, 256GB storage Yes 120 Hz AMOLED screen with Full HD+ resolutionso it compensates for that detail of the SoC very well.
Its rear camera is 50 MP and has a couple of additional supporting sensors, while the front camera is 20 MP. Don’t expect magnanimous image quality, but remember that it costs less than €200. Furthermore, the 5000mAh battery is incredibly good For such a slim phone, it comes with 33W fast charging and also has IP68/IP69K protection.
Samsung Galaxy S25 Edge: with a 200 MP camera and the only one capable of recording in 8K
We have reached the end of this list and the silver medal goes to the Galaxy S25 Edge with a thickness of only 5.8 mm. Its price starts from 1,259 euros.which makes it the most expensive on this list.
However, its processor is the Snapdragon 8 Elite, an unstoppable beast. Furthermore, its main camera is the same as the Galaxy S25 Ultra, a giant 200MP sensor capable of recording in 8K. And not having enough, Its AMOLED screen is the best on the listWhy It also has a QHD+ resolution (with LTPO included).
With it you will also log in seven years of updatesin addition to 15W wireless charging and the best connectivity of the moment. The 3900 mAh battery is perhaps the only flaw, because it consumes really quickly.
Apple iPhone Air: the king of fitness, even if there are those who doubt it
At just 5.6mm thick, the iPhone Air is the thinnest phone 2025. However, there are people who take this statement with a grain of salt. The reason? Unlike the competition, Apple’s measurements do not include the camera module, because if it did it would be a 9.5mm smartphone. But hey, we’re not here to discuss that.
The iPhone Aria It is available for €1,169 at the time of writing this article. However, Its A19 Pro chip also makes it the most powerful and it’s not even that he’s one-handed in other senses.
For example, its 12 GB of RAM brings iOS 26 back, its Super Retina XDR OLED screen with a frequency of 120 Hz is fantastic and Its single 48MP rear camera has brutal performance. Furthermore, this mobile phone does not lose ground compared to its bigger brothers in terms of connectivity and functionality.
It is a machine on all levels, even having the smallest battery of all, with just 3149 mAh of capacity. But this is not a big deal, because iPhone consumption is very well controlled.
And you… What do you think is the best slim smartphone of the moment?
