This is the world's thinnest curved screen smartphone in the Techno Slim. It measures in at just 5.95 millimeters thick, which puts it in the same category as the Galaxy S25 Edge. Except while Samsung was only able to squeeze in a 3900 mAh battery, Techno somehow equipped the Slim with a massive 5,160 mAh unit. Now, we've got a number of tests lined up for this phone, putting it head-to-head against the S25 Edge. But first, let's take a look at what's inside the box where in addition to sending us the phone, Techno is also sponsoring this video where right on top you get a case for the phone. It's nothing fancy, but you know, hey, it's included. Obviously, you get the phone
itself. And unlike most phones nowadays, Techno actually includes a power brick that's capable of charging the phone at up to 45 watts along with the included USBC cable. But here is the Slim itself. And man, this thing just lives up to its name. I mean, it is incredibly thin where, you know, I know on paper it's not technically any thinner than the S25 Edge, but because of the curved edges and the curved screen, it just feels that way. I mean, like the phone can literally hide behind a pencil. And when you have it in your pocket, it's almost like it isn't there. And a big part of that isn't just because of how thin it is, but also how light it is. With it weighing in at just 158 g, which
combined with the 6.78 in screen makes this arguably one of the most comfortable big screen smartphones out there with it having the highest screen size to weights ratio that I've ever seen. Speaking of the screen, the bezels on here are pretty slim. Like they're not the thinnest in the world, but they're right in line with what you'd expect with this price point. And the panel itself though is solid. It's an AMOLED display with a 1.5K resolution. And Techno says it's capable of reaching up to 4500 nits of peak brightness. Of course, I think global brightness is arguably the more important spec when it comes to brightness, where the entire screen is lit up instead of like a small
little window. And in this category, the Slim actually did better than I was expecting. In our sustained brightness test, it was actually brighter than the Edge for the first 3 minutes at around460 nits versus 1320. But by minutes 4 and 5, it did dim down to 622, which brought its average to 1,184 compared to the Edges 1,320, which isn't bad at all, especially considering that this thing has a 144 hertz refresh rate instead of the typical 120 Hz that you see. Like I don't know if that's something that most people can see. I certainly can't see the difference between 120 and 144, but some people swear that they can. And you know, at the very least, it does give this phone some bragging rights, which
on a similar note, let's talk about these lights on the back of the camera system or what Techno is calling mood lighting. Now, I'll be honest, this is probably not going to be the most practical thing that you use on a day-to-day basis, but it does give the phone a little bit of personality. And you know, to be fair, Techno did try to bake in some actual functionality. For example, it'll light up when you get calls and notifications. You get different animations when the phone is charging. There's a low battery reminder, a startup sequence, and there's even this flip to flash gesture. But for me, the main draw of this is just the way it looks, especially with this white and like the clean bar that goes across the top. It just makes this
phone feel futuristic. It's kind of like a phone that you'd expect to see in a sci-fi movie. But here in reality, I think the big story with the Technos Slim is actually its battery. Because usually when you get a phone that's this thin, you expect to give up some capacity. We certainly see that with the S25 Edge only having 3,900 mAh. So, at least on paper, this phone having 5,160 mAh is impressive. Of course, capacity alone doesn't tell you the whole story. Battery life also depends on other factors like the display, the efficiency of the chip, and a bunch of other software optimizations where the S25 Edge does have the advantage of that 3nm Snapdragon 8 Elite versus the 6nm Demenity 6400 on the slim. So, to see
how things actually play out in the real world, we put both phones through our signature 2-day battery test. Starting off with a 1-hour phone call where the slim only dropped by one point compared to the S25 edg's four point drop. Now, we have seen plenty of phones over represent on their battery early on, so I wouldn't read too much into this results, but it does give the slim an early lead. Here in messaging, we have our automated chatbot texting back and forth with each phone, where this time the S25 Edge does better, cutting the gap down to just two percentage points. here in email. It's worth noting that we've calibrated the displays on both phones to 200 nits, so everything is
going to be as fair as possible where after an hour of scrolling through the same set of emails, the Galaxy's comeback continues with it now pulling just one point behind the slim. But it's this browser test that will be telling because we're actually taxing the chipsets more than in the previous tests by randomly cycling through the same set of websites where this time the Techno does better, increasing his lead back up to three points, which is kind of surprising. I was expecting the opposite to happen there during the more CPU inensive task, but it looks like that Demenity 6400 was pretty efficient there. Here in Instagram, we're just scrolling through the home feed like you
would in real life, where I'm not sure how that 144 hertz panel on the slim is going to be able to ramp itself down between the scrolls compared to the Galaxy's LPO display where 1 hour later the Galaxy did have the advantage pulling back within one point of the slim as we move on to the 16-hour standby. Now, everything else being equal, usually it's the phone with a bigger battery that outperforms here in standby. And that is exactly what we see with the Slim doing one point better. Meaning heading into YouTube, the Slim has a twopoint advantage. One thing worth noting here in YouTube is we calibrate the speakers on each phone to the nearest decel count. It's measured
from 2 ft out from the center of the phone screens where because we got the Slim with early pre-release software, there was a bug causing that top earpiece speaker to not work properly. meaning we had to crank the volume up from the bottom firing speaker louder than usual in order to be able to match the Galaxy's dec. But 1 hour later, it didn't really seem to hurt it with the Slim doing it three points better this time. Although I expect the Galaxy to have the advantage here in Alto's Adventure since while Altos isn't the most intensive game out there, it is taxing the GPUs on each phone where that 3nm Snapdragon 8 Elite might have the advantage. But 1 hour later, no, it's the Slim that does better, pulling
another two points ahead. Honestly, I don't know if that was due to efficiency or if the Galaxy's indicator is just being more realistic now. But either way, we are starting to see some real separation with the Slim adding yet another point to its lead after an hour of simulated navigation. In Spotify, we have our robots listening to music where again it's worth noting that the speaker outputs were calibrated to the nearest decel count where 60 minutes later the S25 edg's fall continues with it falling another four points behind. Meaning 26 hours into testing the Slim now has a 12point lead. Of course, things might change here in Snapchat, where this task is just super intensive with the
screens, the cameras, the microphone, and the speakers, and even the Wi-Fi on each phone all being used in a loop, where 59 minutes into the test, the S25 Edges, 22% that it started with fully depletes, at which point the Slim still has 21% left to go. So, there you have it. a 21point advantage for the Slim, which not only allows it to finish with Snapchat, but it also went on to app cycle where we open and close apps in a loop with it being able to go for a full 1 hour and 47 minutes, actually tying the result that we got from the iPhone 15 Pro Max. So, really impressive results there. Now, when it comes to charging the phones back up, the Slim comes with that 45 watt fast charger in
the box, while the S25 Edge supports up to 25 watts, where because the Edge has that smaller battery, it actually makes the two phones look like they're charging at the same rate with each phone hitting 52% after 30 minutes. But in reality, of course, the Slim has a much bigger battery to charge. And as we saw in the battery test, that same 52% will obviously last you a lot longer. But battery life is only part of a phone, right? like performance is arguably just as important. And this is where the Slim takes a slightly different approach to what Samsung is doing with the S25 Edge where while the Edge is powered by Qualcomm Snapdragon 8 Elite, the 5G version of the Slim here
is powered by MediaTek's mid-range Demenity 6400. It also comes with just 8 GB of RAM instead of 12 GB like on the Galaxy, although they do include an option to expand that RAM virtually if you want by another 8 GB if you want. But I'd say the biggest critique I have here isn't the RAM or even the chip, but the storage speed. With Techno going with UFS 2.2 instead of the faster UFS 4.0 that you'll find on the Galaxy, which means you're not going to see those blazing fast app launches or file transfers. But, you know, for everyday stuff like messaging, social media, and browsing, it still is able to get the job done. I mean, I even tried out playing some games like Subway Surfers
and Call of Duty. And while you won't get maxed out settings, the experience on here is still totally playable. And that philosophy kind of carries over to the back where you get a 15 megapixel main camera. And you know, in good lighting, the main camera can deliver some pretty solid results. I got a number of good-looking shots in a short little photo session. But in low light, you do start to see some of the limitations of the sensor. But the good news is Techno added a bunch of AI photo editing tools on here where you have stuff like AI eraser to remove unwanted objects. There's image extender that can add to your background. And there's even a sharpness tool to clean up your shots
if you need it, which you know, considering that the camera isn't the main focus on here is nice to have. All right, so last couple of things I wanted to talk about in terms of hardware is upfront the Slim's display is protected by Corning's Gorilla Glass with Techno saying that the phone also meets militarygrade shockresistance standards. So it should be fairly durable, especially considering how light it is. On the back, inside of the camera housing, you also get an IR blaster, meaning you'll be able to control your TV or other devices, which is always a nice bonus. And then in terms of software, the Slim is running on Android 15 with Techno's iOS over top. So, as you'd expect from a phone in 2025, it
comes with a bunch of AI features. For example, there's an AI call assistant that can answer your calls for you and help filter out spammers. You also get AI writing tools pretty much anywhere that you can type. And Techno even has their own AI assistant on here called Ella, which is powered by DeepSeek, meaning you actually get two LLMs on here, considering that Google's Gemini obviously is deeply integrated. As far as software updates go, Techno is only promising one year of OS updates and two years of security patches. So definitely on the low end of the update spectrum. So I think it's really going to come down to how Techno will ultimately price this thing and you know how much you
care about software updates. But once I have pricing details, I'll update the description down below. But yeah, that is the Techno Slim. I think this is an interesting option for anybody who just wants a big screen experience in a device that's light and comfortable to hold while also having some personality to it. And you know, with its stellar battery life, I think it sets the bar on that front for Samsung and the upcoming iPhone 17 Air, at least in terms of what's possible in this crazy thin and light form factor. But anyways, that is it for me in this video. Big thanks to Techno for sponsoring the showcase.
Thank you guys for watching and as always, I'll see you in the very next
