This modded Android phone brings The Witcher 3 at 1080p ultra settings, blurring the line between mobile and desktop gaming.
When Phones Start Playacting as PCs
There’s a strange thrill in seeing a device rebel against expectations. Witnessing a smartphone run The Witcher 3 at 1080p ultra settings is one of those moments. It’s a testament to just how much untapped power lurks inside our daily tech—power that, until now, was mostly kept in check by design.

Let’s be honest: modern flagship phones are absurdly powerful. Their processors, RAM, and GPUs would’ve been the stuff of desktop dreams just a handful of years ago. Yet, for most users, that performance is throttled for the sake of battery life and heat management. So what happens if you take the gloves off—if you let a smartphone truly flex its silicon muscles?
Unleashing the Nubia Z70 Ultra
You don’t get to record-breaking performance just by wishing for it. The Nubia Z70 Ultra, that Snapdragon 8 Elite beast with 24GB of RAM, became the subject of a rather daring experiment. The screen was carefully detached and relocated to the front of an acrylic custom case. Bold move, right? But this wasn’t just for show.

The brain behind this transformation—a modder going by “ntsow”—mounted not one, but two desktop-grade CPU coolers directly against the Snapdragon chip’s shielding. The goal: eliminate thermal throttling. Power delivery came courtesy of a power bank, making the rig portable in theory, though admittedly less than pocket-sized.
A Hybrid Software Wonderland
Of course, all that hardware potential would go to waste without the right software trickery. This build doesn’t just run Android. It layers a full XFCE Linux desktop through Termux, complete with GPU acceleration—now we’re talking real multitasking muscle. But that’s not all.

On top of Linux, the modder stacked Wine and Box64, tools that allow Windows applications—and yes, games—to run. The result? A phone that’s also a Linux workstation and a Windows gaming PC, all at once. It’s an ambitious fusion, and while the dream of a “single device for everything” still feels a bit futuristic, this project gets astonishingly close.
Turning Up the Heat: Why Cooling Changes Everything
How far can you push a phone when you take heat out of the equation? Turns out: surprisingly far. In the grueling 3DMark Wild Life Extreme Stress Test, this modded Nubia Z70 Ultra achieved 99% stability for 20 full loops. That’s a metric that bested even newer chipsets like the Snapdragon 8 Elite Gen 5 and Apple’s A19 Pro—at least in terms of sustained performance.

Most phones can hit impressive numbers for a minute or two, but thermal throttling soon drags them back to earth. Here, with proper cooling, that ceiling gets blown wide open.
The Witcher 3: Real Desktop Gaming on a Phone—Sort Of
Here’s the showstopper: The Witcher 3, running at 1080p on ultra settings. I’ll admit, when I first heard this claim, I was skeptical. “No way,” I thought. But the reality? The game holds steady at 20–30 fps, with occasional bursts above 30 fps when the phone is overclocked to its max. And the Adreno GPU? Pinned at 99% utilization—this isn’t a half-hearted attempt.

You hook it up to an external monitor, plug in a keyboard and mouse, and it really starts to feel like a desktop battlestation—albeit one that started life as a mobile device.
What Does This All Mean?
Beyond the novelty of running a sprawling RPG on a phone, this mod raises bigger questions about the gap between mobile and desktop computing. Is cooling really the last wall standing? This project suggests it might be.

Still, the build is not exactly portable, nor is it practical for the masses. The elaborate cooling setup, the external display, and the sheer oddity of the form factor mean that, for now, this is more proof-of-concept than consumer-ready. But the boundaries have been tested—and they’re thinner than I thought.
The Fine Print: Caveats and Surprises
As impressive as this all is, I can’t help but wonder if the process is a bit too “mad scientist” for everyday use. The phone, stripped of its screen and entombed in acrylic, loses its identity as a mobile device. There’s also the question of efficiency—how much energy is wasted on keeping things cool? And is all that complexity really worth it, or is it just a fun experiment?

At first, I dismissed the effort as another over-the-top mod. But seeing The Witcher 3 actually run at ultra on a phone-sized slab made me reconsider. Maybe we’re closer to true “pocket PCs” than I realized—if only someone dares to build them this way.
Are Phones About to Replace Your Desktop?
And so, we circle back to the big question: are we on the cusp of smartphones replacing desktops for serious work and play? Not quite yet, but the line between them is undeniably fading. Adequate cooling—and a willingness to experiment—may be the only things holding us back.

Conclusion
Sometimes it takes a wild experiment to show us what’s possible. The modded Nubia Z70 Ultra is more than a curiosity—it’s proof that today’s phones are already knocking on the door of full desktop replacement, at least when given the freedom (and cooling) to perform. Could your next gaming rig fit in your pocket? Maybe not tomorrow, but the future suddenly looks a lot closer.
FAQ
- How does the Nubia Z70 Ultra run The Witcher 3 at ultra settings?
By removing the screen and attaching desktop-grade CPU coolers, the modded phone avoids thermal throttling. Combined with software layers that support Linux and Windows apps, it’s able to handle demanding games like The Witcher 3 at 1080p ultra settings. - What performance does the modded phone achieve in games?
The Witcher 3 runs at 20–30 fps, with occasional peaks above 30 fps under overclocking. This is with ultra graphics settings at 1080p, which is astonishing for a phone. - Is this setup portable or practical for everyday use?
Not really. The build sacrifices portability for performance, turning the phone into more of a desktop hybrid. It’s a proof-of-concept rather than a consumer device. - Why was the screen removed from the original phone?
Removing the screen allowed the coolers direct access to the Snapdragon chip’s shielding, which is crucial for maximum cooling and sustained high performance. - Could this approach lead to consumer devices in the future?
It’s possible, but current consumer phones prioritize slimness and portability over extreme performance with elaborate cooling. Still, this mod shows the hardware is already close to desktop territory with the right tweaks.
